About Dr. Marc Gerdisch,
Heart Surgeon

"Dr. Gerdisch is truly a blessing for cardiac patients. Having had my first stethoscope at the age of 22, I have listened to my mitral valve go from mild to severe murmur over the years.

My first visit gave me confidence that I would be all right by his calm demeanor and confident attitude that he could help me. After my first visit, I felt reassured for the first time that having open heart surgery would truly help preserve my health.

My post-op recovery was amazing having the minimally-invasive port assess surgery. I would have never guessed that 3 days later I would feel good enough to go home.

Even though I was not symptomatic prior to surgery, I feel tremendously better after surgery. My cough that I had for 5 years immediately resolved after my valve repair. It was truly a miracle to listen to my heartbeat normally after years of slowly developing my murmur.

I would highly recommend Dr Gerdisch and his staff. Dr. Gerdisch put me at ease knowing everything is going to be ok."

"Dr. Marc Gerdisch is an incredible surgeon and has a first class surgical support team. He and his team were involved with my care from the first diagnosis indicating the required surgery and all were easily accessible during the prep (several months) to and thru the day of and the hospital stay.

There was never a time that I (and my wife) had any difficulty with information, care needs or help.

Dr. Gerdisch provided a total pain free open heart experience. I just had my 8 week after surgery appointment, I have had no problems, pain or limitations to my recovery.

I am feeling great, back on my bike (indoor cycling trainer) and riding is almost totally back to normal. I highly recommend Dr. Gerdisch and his team, they are the best!"

"I am now 2 weeks post-op and feel the worst is over. Dr. Gerdisch and his staff were great. I am so thankful I waited the 4 months necessary for him to perform it.

Their post-op pain relief program really amazed me. Between the spinal blocks that last 72-78 hours and the incision cryo nerve blocks that last about 2 weeks, I was able to get around and be driven home on day 5 without much pain. It was an 8-hour drive and we did 4 hours each day. I now think all the blocks have worn off and my pain is easily managed with Tylenol 3x's per day. I am really thankful to have this behind me.

They did a re-do repair of the mitral valve, a bovine tissue replacement of the aortic valve and a MAZE procedure. Even though it was the week before Christmas, their team acted like it just a normal fully staffed week with little regard for the holiday. My family was totally kept in the loop the day of surgery and each day we were there.

I would highly recommend Dr. Gerdisch!"

"In September of 2024, I brought my father to Indianapolis from southern New Hampshire to have major heart surgery performed by Dr. Gerdisch. It was a great success!

Five months later, I took him to have an ingrown toenail removed. The morning after this 'procedure'… I heard him yell from his living room- "Jeezum Crow! This hurts more than the heart surgery did!" and it's important to note that he took no pharmaceutical pain relievers after the surgery. Not even a Tylenol!

Why Dr. Gerdisch?

To describe how dedicated, knowledgeable and down to earth this specialist is. You can read about all of his surgical accomplishments. But, to a lay person- that information is difficult to truly understand. It becomes crystal clear, however, when all the assistants, nurses and therapists who are connected to his patients share their admiration.

Why go to Indianapolis?

We live in southern New Hampshire... the most logical place to go for the "best possible" surgery would be Boston. What I did not consider and was not aware of until we had been in Indianapolis for a week was how easy and non-stressful it was to navigate that area for those who are supporting the patient… (versus traveling an hour (or more) into and out of Boston every day would have been a literal nightmare).

Indianapolis is flat. The roads are a grid. A choice of very decent accommodations within a mile of the hospital and restaurants of every culinary culture are abundant… I never factored this into our decision- but it is a big plus that future patients should be aware of.

We were so lucky to find Dr. Gerdisch. He easily gets five stars… Wish we could give him TEN. ⭐️ ⭐️ ⭐️ ⭐️ ⭐️"

"Dr. Gerdisch was amazing from our first meeting until our last post-op appointment. He is very informative and honest, and his confidence makes you feel ready and confident as well.

My surgery went great and the staff helped get my recovery off to a great start! If you have the opportunity to get Dr. Gerdisch and his group to perform your surgery, grab it! He is the best."

"I chose Dr. Marc Gerdisch as my surgeon because he offered everything I was looking for - his expertise, his highly skilled team and the rapid recovery program.

He repaired my valve, I was extubated in the OR, he was able to use a new approach, using port access, which spared my breast implant, and every step of the way he was there, even after my discharge!

My surgery was on Friday and I was discharged on Monday. I've been a healthcare provider for 50 years so I knew what I wanted. Dr. Gerdisch and his team are one in a million! I highly recommend this team!"

"I don't know that I can adequately express my thankfulness and appreciation for Dr. Gerdisch and his entire team. One of the top surgeons in cardio-thoracic surgery in the country, Dr. Gerdisch, instilled confidence from our first appointment through his impeccable bed side manner and direct approach.

His reputation as a skilled surgeon did not disappoint and I was feeling better on day three post-op than I had the entire previous year. There were more repairs to be done than we knew once he was operating but he was able to repair my badly shredded mitral valve, apply a left atrial appendage clip and restore my quality of life even very early on.

The attention to detail by his entire team to avoid infection and complications is unmatched. I felt completely confident and prepared by the pre-surgical team and post surgery was given personal cell numbers for himself.

After care has been amazing from being encouraged to call for any concerns to home health care nursing visits at home. I've appreciated the no opioid approach to recovery and rigid sternal fixation plate closure to my sternotomy has allowed me to use my arms since day 2 and has no doubt made my recovery easier.

I cannot thank this team enough and I'd repeat and highly recommend this team over and over again!"

"Very kind. Detailed thorough description of each aspect of the procedure prior to surgery. Exceptional post operative care and attention to detail from Dr. Gerdisch and staff. Minimal post-op pain and discomfort."

"Dr. Gerdisch and his staff are spectacular!"

"Absolutely remarkable! Dr. Gerdisch and his entire team are the epitome of world-class. They described the procedures and the recovery in perfect detail, and executed their portion.

The recovery was nearly painless. I was never above a 1 on a 1-10 scale with 10 being the most painful. Everything happened as they described prior to the procedures.

What a wonderful group of people and the best cardiac care you could ever hope to find. Thank you to them all! You would be foolish to receive your care from any other group/team/hospital."

"Dr. Gerdisch removed any fears I had pre- or post- operation.

Extensive explanation and handling of my questions. 100 percent successful aortic valve replacement, mitral valve repair, closure of the left atrial sinus node and closure of persistent left superior vena cava with drainage into the left atrium. Closure by rigid sternal fixation. Virtually pain-free post-op and recovery."

"100% the best experience under the circumstances. I was in the best hands from my initial appointment to my post-op release appointment. The Rapid Recovery Protocol 2.0 works! I can't imagine going through this any other way. Dr. Gerdisch and his staff are the absolute best.

The bed side manner is professional yet personal. Dr. Gerdisch and his staff saved my life and I have no words to express how grateful I feel.

I knew the day I left the first appointment that Dr. Gerdisch was the right surgeon and has an enormous heart and respect for his patients and their families wellbeing. I am so grateful and the surgery was a 100% success."

"Dr. Gerdisch did an amazing job repairing three valves. His entire staff is top notch and caring. He was able to repair three valves with no replacements necessary. My recovery was much easier than anticipated and hospital stay was only 3 days. I was back to work by week 3. No issue with pain and no pain medication needed. He is remarkable!"

"I can't thank Dr. Gerdisch enough for giving me a normal heart again. I did a lot of research when I found out I needed surgery and after meeting with him for the consult. I immediately felt he was the one that I was going to trust my heart with. His expertise is amazing, ready to answer any question, and calm any fear.

My experience from consult to post-op follow up was seamless thanks to Dr. Gerdisch's knowledge and concern for the perfect surgery for you. If you are needing heart surgery, I highly recommend Dr Gerdisch and his wonderful team.

The Enhanced Recovery After Cardiac Surgery (ERAS) protocol is nothing short of brilliant. I never imagined you could have open heart surgery with no pain and with the rigid sternal fixation, be able to get back to a normal lifestyle so quickly.

Thank you Dr. Marc Gerdisch."

"Dr. Gerdisch is an extremely skilled surgeon who has performed 6,000+ valve surgeries. He very clearly explains heart procedures and answers all questions. His entire staff is very focused on patient care. I love that Dr. Gerdisch's priority is on repairing the heart valve if at all possible before considering replacing the valve.

The recovery was very fast because he was able to perform minimally invasive surgery and used a nerve block to control pain. For me, this meant that I did not require a prescription for pain medication after the surgery. I was back to normal activities within two weeks! I highly recommend Dr. Gerdisch."

"First appointment we had with Dr. Gerdisch, I knew he was the one to do my aortic valve replacement, ascending aorta replacement, and left atrial appendage procedure. He displayed professionalism, knowledge, compassion and just being honest and down to earth. I didn't even consider a second opinion. I looked at a couple things in needing a second opinion. 1) test results, if those are questionable, 2) the experience with the doctor. Tests results are usually numbers, opinions, etc. Another set of tests wasn't going to change the facts based on my symptoms.

The doctor was a slam dunk. I researched him on this website and immediately learned I hit the jackpot.

My surgery, 4 days in hospital, and discharge was magnificent. Couldn't have gone any better. Minor things going on that's usually expected but Dr. Gerdisch, nurses, technicians, etc was top notch. I told them the reason I'm here isn't great but the way I was treated with care and compassion was excellent.

That's the memory I'll take away. Dr. Gerdisch and team has got this heart valve surgery journey fine tuned. It would be hard pressed to find other heart centers any better."

"Dr. Gerdisch is the best. I did some research on HeartValveSurgery.com and in watching his interviews with Adam really felt like he was going to be the right fit for me. I live in Kansas City and we have a good heart team but not the world class team that Dr. Gerdisch has assembled.

Everyone in his office is amazing and the care is top shelf. Don't be afraid to travel - there are plenty of hotels nearby and of course you have to go to St. Elmo's for their shrimp cocktail and steak before surgery. I had a flailing mitral valve for years with quite a bit of regurgitation. Also enlargement of the heart.

One year later I have zero regurgitation, EF of .60 and heart back to normal size. And a 4-inch scar on my right pec that you can barely notice. Everything was in network with United Choice Plus and zero surprise billings or hassles."

"Dr. Gerdisch was great, his whole team was great. I was extremely impressed. My surgery (an aortic valve replacement with On-X valve & aortic aneurysm repair) went incredibly well. I had rigid sternal fixation and was up and going the next day.

The pain was extremely low, I would call it a 2 on a scale of 1 to 10. A lot of times I had no pain at all. I largely followed the staff's recommendations and made sure I ate even though I didn't want to.

I did the exercises (e.g. walking as I was told) and was sure to put in my whole effort. I ended up being released after 3 days. All the nurses, therapists, doctors (I want to specifically shoutout my anesthesiologist) and advocates were a pleasure to work with. I can't recommend Dr Gerdisch and his team highly enough. A 10 out of 10!!! Extremely knowledgeable, kind, & helpful!!!"

"I had consults with two other surgeons from top-notch well known hospitals before my consult with Dr. Gerdisch. Halfway through my consult with Dr. Gerdisch, I knew I wanted him to do my surgery.

He is personable, explains things well, and is really genuine. I could tell that he is really passionate about what he does. I flew from Florida to Indiana for the surgery, and I have absolutely no regrets. The care that I received was amazing! When I started to get a migraine in the hospital, Dr. Gerdisch allowed my fiance to bring in my prescription medication and the team got it approved for me quickly so I could get relief.

Dr. Gerdisch and his office staff really care about their patients, and go the extra mile to make sure you are well taken care of. I had stomach issues after I was discharged (my sensitive stomach didn't like all of the meds), and Dr. Gerdisch and his nurse practitioner were easy to reach and showed compassion and concern as they helped find a solution. My dad wasn't able to visit me in the hospital, but he still says that if I ever have to have heart surgery again, it has to be Dr. Gerdisch! I agree!"

"Dr. Gerdisch was amazing! He was direct and answered all of my questions. He made me feel important and as though I was his only patient. He was definitely hands on throughout the process. Saved my life ❤️"

"From day one, Dr. Gerdisch was great. His staff were awesome. He did a great job. I have no complaints at all."

"It's without question that Dr. Gerdisch is one of the best heart surgeons in the world. Not only is he an amazing surgeon but he has an amazing team. You can trust they will do their very best for you, and thankfully their "best" is world-class. They are masters of their craft, but what makes this team so special is their ACCESSIBILITY.

When you meet Dr. Gerdisch, you can tell he's just a genuinely good man. He might not remember, but soon after I sent in my TEE disk, Dr. Gerdisch called me himself while sitting in his office reviewing it. After discharge, Dr. Gerdisch gave me his cellphone numbers before I left Indianapolis.

Bottom line, if you're their patient, this team has your back. I don't think there could be a more comforting feeling when navigating such a serious life event. I will forever be grateful for this team, and I know and believe God put my care in their hands for a reason.

Technical Notes (I know I would want them from a review):

• I had a very loud murmur related to mitral valve prolapse with severe regurgitation

• My 1 month post-op ECHO showed NO regurgitation

• I'm over two months post-op with NO audible murmur upon auscultation/by stethoscope (yep, I'm a nurse 😁)

• I had a mini-thoracotomy. I have a 2.5 inch scar on my right chest (yep, right side) that healed great and I'm sure will fade nicely with some silicone.

• I had no real pain post-op. I received a nerve block in the operation room. Two months out and I still feel a little numb under my right armpit and around my right nipple.

• I'm mid-30s. Going into surgery my BMI was approx. 25, I was exercising moderately 2-3 days per week, and would regard myself as in good health.

Get Prepared:

• Start eating heart healthy several months before surgery

• Stop alcohol (and smoking of course)

• Talk to your friends and family and talk to God about this major decision.

I pray that whoever reads this will experience God's peace, guidance and comfort during this challenging time in your life. It's OKAY to be anxious and scared. I certainly was. Take it to Christ."

"His bed side manner is fabulous !!!!!

Repaired or fixed the following: Ascending artery aneurysm, bi-pass blocked vein, leaking valve and one other thing but don't know what it is called. He is the greatest and referred to me by Dr. Kerry Ettensohn. Should anyone wish to speak with me about Dr. Gerdisch, I would be honored. Thank you Dr.Gerdisch and Dr. Ettensohn!!!!!"

"A highly skilled, experienced and caring cardiac surgeon describes Dr. Gerdisch. The team that surrounded him during surgery was, like him, specialist in their fields.

Dr. Gerdisch sits attentively beside you as he responds to questions and explains procedures you will undergo in a calm, confident manner.

Both the pre- and post-operative instructions from all staff were thorough and clear. I highly recommend Dr. Gerdisch."

"There are not enough words to describe how wonderful our experience was with Dr. Gerdisch.

Everyone has been so compassionate, patient, accessible, and have really held our hand through this experience. Learning about Dr. Gerdisch's expertise with the HAART annuloplasty ring, rigid sternal fixation, non-narcotic pain management, and involvement with other ongoing studies gave us confidence he was the surgeon we needed.

In addition, we heard personal testimonies about his skill but, equally important, his surgical judgment. He was confident and prepared to handle my husband's relatively rare case. His follow up with my husband in the hospital, willingness to call me outside of his rounds, and everything else has been so reassuring.

We are thrilled that my husband's aortic valve and congenital aneurysm have been repaired and addressed, respectively. THANK YOU!!!!!"

"All went well. Dr Gerdisch is easy to talk to as well as his staff."

"We were getting ready to move to South Carolina in 3 weeks and I went to see Dr. Gerdisch to get an aortic valve replacement before our move. He recommend a open heart valve replacement because of my age (68) and that I was in good health.

Dr. Gerdisch told me if I did the surgery that I would never regret it and I would be able to make the trip to South Carolina in 2 weeks. He was absolutely right. I came through the surgery better than I could have ever imagined.

Little to no pain after surgery with a quick recovery. I was in South Carolina 2 weeks to the day after my surgery. Everything that Dr. Gerdisch said was absolutely true. Dr. Gerdisch kept my wife informed during the surgery. Six weeks after my surgery, I feel so much better and have no regrets about doing the surgery.

Dr. Gerdisch has perfected his own surgical procedure and it is amazing. My scar is also amazing. No railroad track scare and it is already getting hard to see.

If any of my loved ones or anyone I know needs heart surgery, I will see that Dr. Gerdisch does it. My wife and I both feel Dr. Gerdisch is amazing."

"Dr. Gerdisch did minimally-invasive aortic heart valve replacement and it went great. He is friendly and really cares about you.

More importantly, he is a great surgeon. I was walking 7 miles a day 3 weeks post surgery with little to no pain. Much better than having chest bone cut and having 8 or more weeks to heal."

"I did not have a full sternotomy. Dr. Gerdisch is a very experienced surgeon. He knew about new heart valves and surgery."

"All I can say is that Dr. Gerdisch is amazing. He said he had never seen a heart quite like mine, but he took extra time and was able to figure out how to do the repair. My small incision has almost disappeared. I was swinging a golf club after only 4 weeks. I would and will recommend him to anyone that needs heart surgery."

"Dr. Gerdisch was great. He answered all the questions I had and he explained the procedure in a simple matter. Surgery went better than I could have expected and I had no pain at any time after surgery."

"Dr. Gerdisch and his team were wonderful. They explained everything so well I felt totally at ease before the surgery.

The surgery went very well. My recovery has been borderline miraculous. On the first day home form the hospital, I was able to care for myself. I have 17 steps to get to my apartment and that was no problem for me. I actually went up and down several times that first day.

When the visiting nurse service showed up the next day, the nurse told me I didn't qualify for the service since I was so healthy. Six weeks after the surgery, I was back to playing volleyball. I've had little to no pain in my chest.

His office has always been prompt with answering calls and answering any questions I had. I highly recommend Dr. Gerdisch and his team of professionals."

"This man is simply amazing!!! I will always be grateful to him for saving my life!! I highly recommend him and his team very professional and personable! He took on my surgery when others wouldn't. He's very confident yet humble! Has a true passion for what he does and more important the patient! My surgery was a huge success thanks to him! I thank God for him everyday! Love him!!!"

"After seeing Dr. Gerdisch on an interview, I called his office and his wonderful office manger immediately transferred my problems to him. He asked for all my test records and he then called me himself to discuss what he can do.

I have been suffering for 17 months with extreme shortness of breath and no one would order a TEE test that would explain my problem. I had a TAVR done in 2017 that did not last, and the doctors would not admit there could be a problem. I was told to learn to live with it.

Dr. Gerdisch went out of his way to ensure me that my problem can be corrected. His staff are top notch, the hospital nurses were amazing, and I can't say enough about how wonderful Dr. Gerdisch is.

In surgery, at bedside, or in the office. It is now 9 weeks after surgery and he called me to see how I am doing. I had tears in my eyes that a busy surgeon would take the time to do that.

Oh by the way, I traveled from North Carolina to Indianapolis just for him to do the surgery. And it was the best decision I ever made."

"Dr. Gerdisch is a very professional doctor that truly cares about the well being of his patient. I highly recommend this doctor!"

"After a false positive for autoimmune hemolytic anemia and told to take steroids following open heart AVR 22 May, 2018 to rid the problem, I got a second opinion & it was found that I had a leak in the new valve destroying red blood cells. I had records changed over and a consult with Dr. Gerdisch. It was determined after cath that the sure way to fix was a redo of the aortic valve replacement. On August 21, 2019 I was fortunate enough to have Dr. Gerdisch do the Open Heart procedure and redo the 1st valve replacement.

My stay in the hospital was 4 days. After 4 days home I was released by visiting nurses and within a week was back on the treadmill. What a different experience! With Biomet plates instead of wire holding chest together I was able to move arms and exercise. Not to mention being able to sleep. I have not taken the first pain pill and am now after 3 weeks back up to 7 miles 4 days a week. No 18 wks. rehab or physical therapy like last time. I can not thank Dr. Gerdisch, his staff and nurses there for taking all the fear out of my experience. From my personal view, I can honestly say I now know the difference in procedures and if I ever need anything done, my hope is that Dr. Gerdisch and his staff will take my case on."

"I had a minimally-invasive heart valve replacement. So relieved that Dr. Gerdisch had the knowledge and skills to do this surgery. He made me laugh at times. Also, he was very honest about what will be done. Thank you Dr. Gerdisch!"

"Dr. Gerdisch was recommended by an unaffiliated cardiologist as an excellent surgeon who specializes in minimally invasive valve repair/replacement. He explained what he felt he could do surgically to improve the situation and was very patient with all the questions I and my family members had for him. He explained the risks, yet conveyed confidence at his ability to achieve a successful surgical outcome. He, his colleagues and hospital staff provided excellent care and delivered on a successful outcome."

"Amazing Doctor... Feel very blessed and lucky that we chose Dr. Gerdisch, recommended to us by Dr. Hogan, Logansport Memorial Hospital. Very awesome team of Doctors and Nurses. Thank you to all that helped and took great care of me. Surgery went as the Doctor said and the recovery was quick, no pain and hardly a scar for a reminder. Thank you Dr. Gerdisch from our family! 💗 The Clark's"

"Dr Gerdisch said that I was not his typical patient. So, he got me enrolled in a FDA clinical trial involving a beating heart surgery with Rechord. The recovery had been pain-free and smooth. I can not say enough positive things about my whole experience with the cardiologists, the surgeon, and the nursing staff that was associated with my recovery."

"I had a right-side mini-thoracotomy access to repair both my mitral and tricuspid valves which were severely leaking by the time I finally found my top-notch surgeon and yielded to surgery. After having watched many online lectures by surgeons, immediately upon watching his medical video, I knew that he was the right doctor for me! I traveled by train for two days and nights to Indiana (the flying pressure would have been too much for me then) and stayed for nearly a month of medical and emotional preparation and getting to know my surgeon. He, his office staff and medical team were very accessible, welcoming and professional. He is a rare surgeon who is willing to discuss questions, ideas and options and I appreciated it as it greatly comforted me prior to surgery. His "light touch" of both personal perceptiveness and engaging, "light-hearted" humor brings a manner that quickly lessens tension! My family had encouraged me to go to a large, famous hospital, but I doubt if their staff would have had the luxury of tolerating my intellectual curiosity given their very large caseload and tight consultation and surgical schedules. Dr. Gerdisch is very pleased with my results as I am on the road to recovery now! Only half-joking, I proudly say that I am now good for another 200 years of active living!"

"I stayed in the hospital five days taking only Tylenol for pain. When discharged, I was told I could move my arms and lift 10 pounds, They installed SternaLock brackets to hold my sternum together. I had no pain or loss of movement. After 3 weeks, I played tennis and served without problems. Still working on my strength. But, I'm able to run some. Dr. Gerdisch was super with his communications to my family and myself. He gave us his personal number to call if needed."

"Completely amazing, supportive, positive, informative and so, so nice. The entire staff including Dr. Gerdisch were awesome. I don't want to do this again but if I had to I would choose Dr. Gerdisch 10 times out of 10 and his staff. Thank you so much for giving me a better, healthier life."

"Dr. Marc Gerdisch did a great job explaining what would occur during my surgery. In my opinion, he is a very talented surgeon. The results of my surgery has exceeded my expectations. My hospital stay was only three days and I have had no pain or problems. I have been released to go off after only eight weeks after surgery. I am feeling a lot better and have much more energy. My motto is a "ton of gain with zero pain." I would highly recommend Dr. Gerdisch and his team. They were wonderful."

"I have nothing but good things to say about Dr. Marc Gerdisch. I first met him in 2007 after my 1 and only afib experience. After a cardioversion the afib was gone. My cardiologist recommended I at least meet with Dr. Gerdisch because in time he would be fixing my heart. I was sent to talk to him again in early 2018 by my cardiologist Dr. Rao. He was excited that he believed my aortic valve could be repaired and saved by Dr. Gerdisch. We met and came to the conclusion that it was time to replace my aortic root which was now 5.0cm and repair my moderate to severe leaking aortic valve. Dr. Gerdisch has a fantastic bedside manner and is always ready to answer all of my questions. He has a great way of making you feel comfortable. He has done thousands of heart valve surgeries and to me is a pioneer in his field. He did successfully repair and save my aortic valve as well as replacing my aortic root too. After surgery he told me that my valve had no leak anymore. My recovery has been great and I've had little to no pain since I've been home. I had my follow up with Dr. Gerdisch today and he said my echo looks perfect and I have NO leak at my aortic valve and he can no longer even hear a murmur. I'm 1 month out from surgery and can drive and do most things. I'm just starting cardiac rehab to make sure I can be in the best shape as soon as possible. I feel great. Dr. Marc Gerdisch has been nothing short of amazing. I highly recommend him. He has saved my life and I look forward to a long full life to enjoy with my wife and daughter. God Bless you all!"

"Surgery was actually for my 85 year old father, Harold Demerly. Our entire family was treated with kindness & professionalism. Hospital staff was friendly, we were greeted with smiles and personally escorted to the appropriate area of hospital, after registering. It was a great feeling to know, staff enjoy their jobs.

We have NEVER experienced this kind treatment in Lafayette, Indiana. Dr. Gerdisch's staff was kind and made us feel like we have known them all for a long time, even though we were just meeting them. The team work between Dr. Shaikh & his staff and Dr. Gerdisch & his staff made my father and our family feel comfortable that we were where we should be. We made a few trips for tests in preparation of the TAVR Surgery, and every trip was a WOW experience. The entire team relieved our stress that comes along with a family member having surgery. We will recommend BOTH of these doctors. Thank you so much for the wonderful care you gave my father and the best Christmas present possible, giving my father a better quality of life. God Bless!"

"The diagnosis after my angina warning scared me! I bought Adam Pick's book (wow, he went through a lot of issues), fired up the web and talked with many acquaintances that had undergone heart surgery. I knew that I wanted the least invasive approach to my needed aortic valve replacement and was not satisfied with the answers received at local hospitals (good institutional stats but not nearly enough surgical experience and recommended full-sternotomy there). However, I had plenty of time to research, and I did! All the major heart-valve hospitals were reviewed, regardless of distance, and many of the major surgeons.

Now I know that my choice of Dr. Marc Gerdisch as the surgeon for my severely stenotic aortic valve replacement was the right one. His practice is not in my area so I had all tests done at a local hospital and sent the results to him for review. In my case, he was able to perform a minimally-invasive procedure (with a horizontal incision about three inches long) which is resulting in a shorter recovery period (eleven days now since operation, six of them in the hospital). NO PAIN MEDICATION since discharge.

Sure, Gerdisch has a number of "firsts" in the field and is, obviously, an intelligent researcher; but he's also a dedicated, hard-working guy! Surgery was scheduled over a major holiday (because during my office visit he determined that time was a factor) and I was surprised that he asked one nurse to call him with a lab result at 4:00 AM and called in at 4:00 AM another time to inquire about another lab result which required some coordination. So, do the research necessary for your particular circumstance! But if Dr. Marc Gerdisch comes into your browser, give him a serious look. I feel that you will be glad you did!"

"Dr Gerdisch is one of the best cardiovascular surgeons in the country! I had an ascending aortic aneurysm that needed repaired and needed an aortic mechanical onyx valve placed. Dr Gerdisch was flawless and did a remarkable job in performing my surgery as well as the care I was given afterwards in the SICU by Dr Gerdisch and all of his staff!

I had researched many surgeons and as an RN, Luckily I knew by word of mouth in my profession that Dr Gerdisch was the best! I was completely at ease going into this surgery! I knew I had the best surgeon for what I needed done! He is so articulate, smart, professional and caring! You could not go wrong by picking Dr Gerdisch! I would reccomend him to anyone! He exceeds all standards as does his staff! He expects the best from his colleagues and they are all very goal oriented when it comes to his patients and the care they receive! I am truly blessed to have known to go to Dr Gerdisch! He is one in a million! Thank you so much Dr Gerdisch for everything you have done for me!"

"I was diagnosed with aortic stenosis. I had a genetic valve defect. Dr. Gerdisch took the time to explain to me everything that was going on and what he would be doing. He encouraged me to ask any questions that I might have. He even explained to me that my children had a chance of having the same defect. My daughter was with me and he took the time to listen to her heart and order a test for her. Dr. Gerdisch replaced my valve and did quadruple bypass. I was in the hospital for 6 days. I had wonderful treatment while I was there.

I am now 7 weeks post surgery. I am doing great. I am back to work part time and getting stronger every day. If I have any questions I feel very comfortable calling his office. He and his staff are wonderful.

I would recommend Dr. Gerdisch to anyone who needs heart surgery. I have recommended him to friends and they love him as much as I do."

"This was a very informed and good experience. Dr. Marc Gerdisch could not have been better. I would highly recommend his services."

"Outstanding experience and excellent bedside manner. Dr. Gerdisch is an awesome doctor and surgical results were great."

"Good bedside manner. Great staff. Exceptional surgeon."

"I can't imagine a more perfect experience. Dr Gerdisch's bedside manner and my surgical results were wonderful."

"I'm very lucky that i was able to have my HEART in the hands of Dr. Gerdisch. He has given me several more years to enjoy my family and precious time with my six grandchildren. His assistant, Tara was always very helpful giving me the confidence that my progress was on tract. I feel the pre-op care I received prepared me to have a speedy recovery. I was only in intensive care for 26 hours and was able to walk to my new room and was able to be released 5 days after surgery. This had nothing to do with insurance, it was all about the excellent care I received. Once again, Dr. Gerdisch thank you for saving my life."

"Dr. Gerdisch is excellent! Not only is he a skilled surgeon, he has a wonderful bedside manner. He is very personable and always answered my questions in a manner that was easy to understand. His office staff was very helpful every time that I called and during my hospital stay I received exceptional care from the nursing staff. The surgery was a complete success and I feel great!"

"Dr. Gerdisch is amazing!

At age 55, this was my second mitral valve surgery, and my last... My new valve has restored my quality of life, and I have an active life! Dr. Gerdisch used sternal plates, which reduced my post-surgery pain by at least 50%. I was able to use my arms right away, and I feel it reduced my recovery time by at least 2 weeks.

Thank you Dr. Gerdisch!!"

"Dr Gerdisch is Awesome and I owe him my life!!! He was wonderful and very caring. Once I met him, I knew I was in great hands. I am a complicated case as I am told, I am dialysis patient, prior open heart - 7 bypass, double leg amputee, vascular disease, Gillian barre and cancer survivor with many drug allergies. Dr Gerdisch stated that he did something that he has not performed before. He did not want to open up my sternum because I need my arms to transfer since I am an amputee. The recovery time would be too long and rigorous. He went in to the side of my chest to repair a valve and through the neck to replace a valve in one surgery. I was home for Christmas!!! Everyone on his staff is also Great and personable. I would recommend him."

"Dr. Marc Gerdisch and associates provided top-notch care for my mother throughout the whole process. She was diagnosed with severe mitral valve regurgitation and her cardiologist recommended surgery. I did not want the open heart surgery if possible, but that was the only option in my mother's immediate area. My mother doesn't drive and lives in northern Indiana; I live in Chicago. I searched for a highly respected doctor within my mother's network who wasn't too far away. We eventually found Dr. Gerdsich and associates. They were very accommodating with our needs and were able to work around our schedules effortlessly. I'm writing this in the days leading up to my wedding, and we had picked Dr. Gerdisch based off overwhelming recommendations and the fact that he could do a minimally invasive procedure to reduce rehab time leading up to the wedding. Needless to say, the procedure was a great success and the whole process was handled very well. Fast forward to today, and my mother is happy, healthy, and ready to celebrate my wedding day! I thank Dr. Gerdisch and his associates very much for all their help and kindness. I highly recommend them to anyone who may require heart valve surgery. They not only do the job medically, but they really care for their patients as not just patients, but family whom they are helping get back on their feet!"

"I could tell he was A-1......have been told not every surgeon could have fixed me. I don't even know what all he corrected as I have had some depression issues since the surgery....my husband passed away in 2016 also. But I healed up fast and was able to use my arms right away. Unfortunately, I had Seratonin Syndrome, and it has affected much more than the surgery.

Dr. Gerdisch is top level."

"I was diagnosed with an ascending aortic valve aneurism. I was born with a bicuspid aorta valve which started leaking. I am 62 years old. This leakage caused an aneurism 5.8cm. I am a non-smoker and always took good care of myself. I was shocked after learning the diagnosis. I was experiencing tiredness and shortness of breath. Within 2 weeks I was scheduled for surgery which I feel saved my life. I received an onyx valve and a new artery. Very pleased with Dr. Gerdisch and his staff.

I am out 6 weeks, involved in rehab, my life is getting back to normal. Never felt better! I would recommend Dr. Gerdisch. This was a very good experience under very stressing times."

"Dr. Gerdisch treated me with the utmost care and respect. His thorough analysis and surgical skill have restored my relative good health and dramatically improved my quality of life."

"I give Dr. Gerdisch and his team the strongest of recommendations. I did extensive research using the incredible HeartValveSurgery.com website and selected Dr. Gerdisch because: (1) I wanted a minimally-invasive thoracotomy procedure; and (2) Dr. Gerdisch received superior ratings from his patients. His excellent office team was compassionate, helpful and efficient. When I spoke with Dr. Gerdisch, he addressed all of my questions, and his expertise produced the highest level of confidence for me. He's very caring, and has an excellent bedside manner. If you do research on Dr. Gerdisch, you'll discover he has developed very innovative surgical approaches that produce the best possible outcomes for patients. I had high hopes for a smooth and quick recovery, but I have to say my aggressive expectations were exceeded! I'm still surprised that my recovery has been so rapid and smooth. I live in Washington, DC, and traveled to Indianapolis because I knew Dr. Gerdisch was the best surgeon for me. I am eternally grateful to have found such an excellent cardiac surgeon!"

"I felt very lucky to have Dr. Gerdisch do my surgery. He was able to do 2 procedures that other surgeons could not have done. I was very happy with the whole experience."

"Explained in detail the whole surgery. Came around after surgery several times but also he has a team of caring and knowledgeable cardiologists that kept checking on my recovery until I was dismissed. Going on three years without any problems. My cardiologist in Ft Wayne, IN looked at last echocardiogram and said he could not tell I had a valve replacement and was using it in training his students."

"Dr. Gerdisch is a great surgeon. The best in the state."

"Dr. Gerdisch repaired a >6 cm. ascending aortic aneurysm as well as replacing my failing bicuspid aortic valve with a new On-X mechanical valve. The surgery was flawless and I spent only four days in the hospital before being released. Dr. Gerdisch used titanium plates and screws to close and hold my sternum together, a vast improvement over wiring the sternum. My recovery has been remarkable with very little pain. Five weeks after the surgery I am almost back to all my activities from before. Thanks Dr. Gerdisch for a perfectly performed surgery and your kind bedside manner. I can, without qualification, recommend this renowned surgeon."

"The first time that Dr. Gerdisch saw me he told me in a confident, but humble manner that he was the best man to do the type of surgery that I required. My first thought was, "Whether that is true or not, it had better be true when you step up to the table to work on me." It turns out that he is confident for a reason. He is the best.

My case was complicated by the fact that I have Parkinsons Disease, also. Fortunately, my caregiver is a retired RN who just happens to be my wife. I was impressed by how he respectfully listened to her input and included her in the plan. Dr. Gerdisch didn't just blow her off as being unimportant as some other doctors may have. Upon release from the hospital, he took the time to explain the care plan with her.

I would recommend Dr. Gerdisch and his team any and every day."

"Dr. Gerdisch called me personally and talked to me over the phone about my situation before I even made an appointment. He gave an excellent explanation of what was going to happen, with confidence and a willingness to answer all my questions. Everything went as explained and everyone on the care team was wonderful. My recovery has been great and the incision is minimal (through right side). Not having a sternotomy played a huge part in my quick recovery. He is an amazing surgeon."

"Dr. Gerdisch is a wonderfully talented surgeon. He is also truly interested in patient outcome and progress. My surgery went very well with excellent results.

I highly recommend him."

"I had a quad CABG in 2001. June of this year, I had a valve and CABG done by Dr. Gerdisch. I only wish he could have performed the surgery in 2001. I had very little pain and the recovery time was extremely shorter than my first surgery. If I need and further surgery, you can bet I will seek out Dr. Gerdisch. Have nothing but high regards and confidence in him."

"I am one of Jehovahs Witnesses and Dr. Gerdisch quickly assured me of his willingness to work with me regarding bloodless surgery to replace my aortic heart valve. He welcomed our questions and answered them all to our satisfaction. I had complete confidence I had found the best surgeon and my date was set for June 1, 2016. I was in the hospital for 5 days. He saw that I was given excellent care, my echocardiogram revealed excellent results and I know from experience I did make the best choice, He is kind, caring, and a very skilled surgeon. I had no doubt he would honor my convictions regarding my faith and that was the most important quality to me. I would recommend him with full confidence to anyone needing a serious surgical procedure."

"I'm a 53-year old male, heavy duty truck mechanic, with Fibromyalgia, Diabetes, and a few other problems. My new family doctor recommended Dr. Gerdisch. I have known about my deteriorating bicuspid heart valve for about a year and a half. I have enough body aches and pains that I did not want to get the surgery done due to that they split your chest open. My family doctor asked me just to see the surgeon and talk with him.

Let me tell you that I am really glad I did go talk to Dr. Marc Gerdisch. He said there were three ways to do the surgery. First, a full chest split. Second, a partial chest split. Third, a newer type surgery a 3" to 4" incision on the right side, using special tools they can go in and replace it. But, it all depends on the results of the CT scan. My result came back came back with the right location of the heart valve.

I was concerned about time off from work. He said with this procedure anywhere from a month to three months depending how your body heals. After the surgery I was in the hospital 5 days. The last day or two was trying to get my blood (INR) at the right level. The entire operation went great. I remember going into the operating and that was it.

I am very thankful that I listened to my primary care physician and that he recommended Dr. Gerdisch. There are not enough nice and great things I can say about Dr. Gerdisch. He is down to Earth and was easy to talk to. You just get that comfortable feeling like you have known him forever when talking to him. I went into the operation with 100% confidence that everything was going to be ok. It's just the way Dr. Gerdisch and his staff make you feel. It seems like everyone has heard of him and nothing but positive things to said about him. Even medical personal from other hospitals have heard of him and had nothing but good things to say about him. Whether you are from Indiana or Florida, California, Alaska, Maine or wherever don't do it without seeing Dr Gerdisch. Google his name and read about him. It's been seven weeks and I'm doing great just waiting to get clearance from D.O.T then I'm back to work. In a brief closing statement. This new type surgery is the way to go. Not much pain after and a shorter down time. Dr Marc Gerdisch Thank you!"

"Dr. Marc Gerdisch and his support staff are outstanding. I am so glad that he was selected as my surgeon. During my operation, he performed several procedures including repairing the mitral valve, tricuspid valve, performed the maze procedure for A-fib and reduced the size of my enlarge atrial chambers back to the normal size. I understand it is rare that this many procedures are performed in one surgery. but with his thousands of successful surgeries as his experience, he performed them successfully.

At 8 weeks, I am walking over 5000 steps per day, enrolled in a rehab program, and feel very good. I have every reason to believe that I will make a full recovery.

Thanks to Dr. Marc Gerdisch and his excellent support staff for their expertise, professionalism and unbelievable skills. I would recommend Dr, Gerdisch to anyone who knows they have one chance to get it right, so why not go to the best."

"I cannot thank Dr. Gerdisch and his staff enough. Dr. Gerdisch was very personable every time I met with him, both before and after the operation. I had done lot of research before my operation on who is the best at what he does and his name kept coming up. And for a good reason. He is the best! My mitral valve was very bad, he called it a Barlow valve. Most other surgeons would have had to put in a mechanical valve, but Dr. Gerdisch repaired it and it now functions with no regurgitation.

That is why I came to him. He also performed an ascending aortic repair. I would recommend Dr. Gerdisch to anyone that needs heart surgery. Besides being a great surgeon, he has very good beside manners and a very good sense of humor. I can't thank him enough for restoring my heart and life so I can enjoy it with my wife and kids!"

"Dr. Gerdisch had a bed side manner that was very friendly. He answered all our questions (and we had a long list) and ended up using an incision under my right breast instead of doing a right-sided thoracotomy which helped with heeling faster. My results are great! Was back to jogging after my one month post-op with him."

"The manner in which Dr. Gerdisch operates his practice gives high confidence that one's particular case is receiving personal attention and that alleviates the natural anxiety of significant surgery. His intensity, attention, and clarity give one absolute confidence that one is in the right hands for a major life event. Nurse Practitioner, Tara Lowe, was also especially helpful at various stages of this lengthy process. Whenever I contacted Dr. Gerdisch's office someone was immediately available and helpful. The level of professionalism and empathy I experienced in every encounter was truly special. Dr. Gerdisch performed four procedures on my diseased heart, correcting all the issues. He predicts with high confidence that my heart will now outlast the rest of my body. I am recovering very well on a supervised exercise program."

"Dr. Gerdisch was wonderful throughout the procedure. He answered our questions, visited after the surgery, and followed up after after we returned home. The hospital staff were professional, friendly and always positive. I was home taking walks in the park two weeks after surgery. We highly recommend this team."

"100% satisfied. Dr. Gerdisch spent a lot of time repairing my mitral valve. He is very easy to talk with, answered all my questions and kept me informed. All of his staff pre and post surgery were great."

"The expertise and reputation of Dr. Gerdisch made me very comfortable and confident with my choice of him as my heart surgeon.100% satisfaction with everything before and after my surgery. I can't imagine a better experience than I've enjoyed with Dr. Gerdisch. I highly recommend him to anyone facing these most serious medical procedures."

"My experience with Dr. Gerdisch, and his bedside manner, was good. My surgical result was excellent. I would recommend Dr. Gerdisch to others."

"I am so thankful to have had Dr. Gerdisch preform my surgery!"

"Outstanding! Dr. Gerdisch is the best! Very kind, understanding and easy to talk to. (He has a great sense of humor, too!) Made me feel like I was his only patient. He also found and repaired an aneurysm in my aorta that I didn't know I had. I was home in less than 5 whole days. I had my surgery about 8:00 a.m. on Monday and was released to go home the following Friday by 3 pm. I can't say enough good things about Dr. Gerdisch and his staff. I would highly recommend him to anyone facing heart surgery."

"I highly recommend Dr. Gerdisch!"

"Diagnosed with severe aortic stenosis. Referred to Dr. Gerdisch for the surgery. I had a lot of anxiety about what I was about to undergo but after meeting with Dr. Gerdisch i found him to be very reassuring and thorough in his explanation of what I was about to experience. He is a very positive and pleasant physician who has outstanding credentials. I would recommend Dr. Gerdisch."

"Dr. Gerdisch is and his team are at the top of the list. He is caring and excellent at his job. Words just don't describe how grateful we are. Thank you all very much."

"Can't say enough about Dr. Gerdisch. Doesn't take much of an internet search to learn that he's a superstar. He has an amazing bedside manner, very humble, takes any time you need and no question seems beneath him.

I can't express how grateful I am to have him here so close. I would have definitely traveled to experience his gifts and talents."

"Couldn't of had a better experience with my surgeon, Dr. Marc Gerdisch. If you have heart valve problems, I highly recommend him."

"Marc Gerdisch is outstanding. I would recommend that someone who needs valve surgery should come and get him to do it. The surgery was a complete success. Marc is known nationally and goes all around speaking about his techniques, some of which he pioneered.

Dr. Gerdisch's number one concern is the patient. He has great empathy for his patients. He is glib with a great sense of humor that cannot help but put you at ease. He explains things thoroughly and always answers questions.

Dr. Gerdisch is also surrounded by an outstanding group of surgeons, cardiologists, and nurses. They are so supportive and are a real team. I had, by far, the best treatment of any place that I am familiar with.

All told, you couldn't be in better hands."

"After thorough research, it was a no brainer to go with Dr Gerdisch for my AVR. His credentials and accomplishments are impressive. With over 2,500 valve repair/replacements, he is a true pioneer involved with everything concerning the heart and it is truly obvious, he loves and has a deep passion for what he does.

I felt really comfortable talking with him pre-operation and definitely knew I would be in the very best of hands during my surgery. Dr Gerdisch is very competent and confident in his practice and leads his entire team to give their utmost best for the patient while expecting no less. It doesn't take long to realize this. During my journey of office visits, I noticed that anyone familiar with him spoke nothing but very highly in his regard. You could tell that he is respected in every way throughout the outpatient and inpatient care community.

Furthermore, my entire family was astonished with the communication, care, compassion, and consideration given during my surgery. I would recommend Dr Gerdisch without reservation to anyone needing any type of heart surgery."

"Dr. Gerdisch tailored my surgery to my specific needs by using a less invasive procedure, which enabled me to return to work in four weeks. My surgical results are amazing. Adverse morphological changes in my heart that occurred due to my bad valve have already begun repairing. My heart is now within normal functional limits and expected to continue improving for the next two years. I feel great.

Dr. Gerdisch spent all the time necessary with me to explain and answer all questions. His demeanor, experience and his knowledge of the latest relevant research provided a high degree of comfort and confidence that I would receive the best care possible. Thank you Dr. Gerdisch!"

"This man is a God-given blessing. He is personable, and explains the procedure to you completely. His work is impeccable, and definitely shortens your recovery from start to finish. His staff is caring and efficient in all aspects of the procedure. I came through with no pain, and home in 6 days. Oh did I mention he is no. 2 in the NATION? You can reach him at: Cardiac Surgery Associates, S.C. 5255 East Stop 11 Road Ste. 200 Indianapolis, In. 46237 (317)851-2331"

"Dr. Gerdisch has excellent bedside manner, always dressed impeccably when he met patients, he showed a lot of respect for his patients and his position, He is very patient and gave expert answers to all my questions before and after the surgery.

My mitral was in pretty bad shape judging by the severe back flow I had at the time, looking at the picture before surgery part of it already loose from its detachment. As an expert in "aggressive heart valve repairment" Marc was able to save and repair it instead of doing a valve replacement, I am very grateful for that.

The surgery went smoothly ( include mitral valve repair and reinforcement, a single bypass) and took 4-5 hours. So far five and a half week from surgery, my incision is healing nicely thanks to Marc's craftsmanship my heart has not had the slightest discomfort.

From my opinion Dr. Marc Gerdisch is a genius at what he does. Some nurses told me Marc is like a machine on surgical table because of his quickness, his precision and his many unique ways of doing things. looking at the picture of my valve after repair, looking at how well my incision was sutured I feel Mark is also an artist, he has truly elevated his work to a new level."

"Selecting a surgeon to re-do my aortic valve replacement was difficult and challenging as most surgeons seemed to have a "specialty" valve or technique that they used routinely.

I had a very bad experience with my first aortic valve replacement in 2010. The bovine tissue valve showed a rapid calcification and deteriorated quickly. In selecting a surgeon, I considered the track record of Dr. Marc Gerdisch's surgical accomplishments.

A colleague of mine, who is a physician that had worked with Dr. Gerdisch, strongly recommended him as a top-notch cardiac surgeon. Dr. Gerdisch's upbeat communication style gave me confidence that he was versatile and sufficiently skilled to successfully insert any valve that I chose. He patiently answered all of my questions, no matter what time of day I contacted him. Most impressively, he listened to my numerous concerns that were based on my previous experience and addressed each one, thereby minimizing the post-surgical complications and distress. I had the On-X mechanical valve implanted in June.

My progress toward recovery is significantly more rapid and less painful than the first surgery - note "re-do" surgeries are typically higher risk and often associated with more complications and longer recovery times. My most recent visit at 7 weeks post, confirmed good valve placement, excellent heart function based on the echocardiogram, normal sinus heart rhythm, good lung function, and rapidly-healing incisions and sternum.

I already feel better than I did going into surgery. With confidence, I can definitely recommend Dr. Gerdisch based on my experience."

"Top notch!! Dr. Gerdisch is not only a great surgeon but a great man as well. He cares for the family as well as the patient. I probably would not be here today if it wasn't for Dr. Gerdisch."

"Dr. Gerdisch and his team was very professional. They made sure we understood all the procedures and treatments before and during and after the surgery. I am very pleased with the results. I have more energy now that the valves have been repaired. I have had very little side effects and am getting my strength back as I go through the rehab sessions. I can not say enought about Dr. Gerdisch and his team. I would recommend them to anyone facing heart susrgery. They are the best."

"Outstanding. From diagnosis to testing to surgery to recovery to rehab. Obviously not a fun experience, but the professionalism and care were more than I could hope for. Thank you to Dr. Gerdisch and all involved."

"No better surgeon than Dr. Gerdisch."

"My cardiovascular surgeon is one of the finest surgeons you will find any where in the United States and he should be at the top of any one list seeking to have heart valve surgery!! Doctor Gerdisch performed my aortic valve surgery and had me on my feet and feeling like a new man within a few days!!

Surgery was the morning of March 16th 2015 and by the 19th day of March, I was walking out of the hospital feeling great!! What do you offer a man that has given you another chance at life?? He and the other doctors and the nurses there were awesome!!! From my first appointment to my most recent appointment this morning!! I had an echocardiogram and everything was great!! I am a happy man today thanks to this fine team of what I believe is the 'Best of the Best' cardiovascular team any where!! And the nurses and the technicians were very helpful caring and explained things in a way that I could understand. Also, my family had a comfortable place to wait during my surgery! I could not have asked for better quicker and more caring service from the receptionist to the housekeepers to the kitchen service and great meals and service to the nurses and doctors!! Thanks for taking good care of me. My family was also impressed and we would highly recommend Doctor Gerdisch and his team to anyone any time!

From the bottom of my Heart thank you all you all were Awesome!!!"

"I cannot recommend Dr Gerdisch enough. He is so experienced and so professional. I was impressed from the first meeting and everything went so well. Comforting to have someone like him in your corner."

"Dr. Gerdisch did an excellent job explaining what to expect prior to the aortic valve replacement. I am pleased that his skills allowed me to recover faster and have less of a scar."

"I was in the hospital only 3 days. I felt great without pain or discomfort. The hospital is excellent from admission to discharge. a very caring and patient orientated staff. I would also recommend the anesthesiologist is very adaptive in using procedures that are best for his patient. Dr Gerdisch is ranked as one of the top heart surgeons in the nation. I would definitely agree. I would recommend him for his skill and his personal caring manner."

"Very compassionate but also very business like. Always came in with a smile and answered any questions I had, I recommend him highly."

"I was very impressed with Dr. Gerdisch and everyone on his staff. A very high level of care. His NP Tara is excellent, and very helpful. Anytime I call the office, someone either gets an answer for me right then, or they call me back quickly. He explains things, and takes the time to listen to you. I highly recomend him."

"Dr. Gerdisch is a pro at what he does. I felt like I was in the hands of the very best. He answered all my questions and gave me all the information I needed to make well informed decisions concerning my surgery. I had excellent results and would not hesitate to recommend him very highly. If and when my valve needs replaced again, he would be my first choice."

"What a wonderful experience with a world-class surgeon and person. The entire experience was nothing but exceptional, from surgery, to the hospital stay, to the follow-up care. If you desire a surgeon that you can have confidence in, this is THE ONE!"

"Dr. Gerdisch and his entire staff were amazing. I had multiple surgeries in 2001 at a different hospital with a different surgeon that did not go nearly as smooth as this one. Dr. Gerdisch and Dr. Labin, my newcardiologist, actually discovered some flaws in my heart that my other doctors had over looked for about 3 to 4 years. If they did not jump all over my case as quick as they did, I would not have made to this years Thanksgiving.

They literally saved my life. My recovery, the surgery and everything leading up to and following the operation was also made smooth and easy by the Dr. Gerdisch staff. After meeting and talking to him, I was actually calmed by the fact he was doing the operation because he truly cares about helping people and is he very confident about what he does. Do all the research you want, the more you read, the more impressed you will become.

Dr. Gerdisch is the man and I am very thankful for him."

"On Nov. 14, 2014, Dr Marc Gerdisch replaced my aortic valve. He also did a graft bypass at the same time. This is my second open heart. Plus, I have 7 previous stents. On day 5, I was able to go home and back to work. On December 22, I'm feeling great. Dr Gerdisch explained everything in great detail before and after the surgery in a personal, caring manner. His staff is also top of the line. I HIGHLY recommend Dr Gerdisch for any heart valve surgery. He also travels world wide to train other valve surgeons on best procedures."

"I found after much research that Dr. Gerdisch is the best surgeon in the Midwest for valve replacement and Maze procedure. I had a quite complicated and serious open heart procedure. Dr. Gerdisch was a perfect match and is so kind, caring, and genuinely interested in me as a patient. The recuperation will take some time for me to return to my old self and activities, but it is expected with major surgery. Dr. Gerdisch is concerned about every little detail in my surgery and recuperation. The scar is the very minimal, and the surgery itself was literally pain free. I would highly recommend Dr. Gerdisch as a surgeon and thank God every day for sending me to him. They both saved my life!"

"Dr. Gerdisch did a fantastic job! I was scared about all of this at my young age! He gave me a book to read on the surgery and gave assurance that I would do fine. I could not have asked for a better doctor! I am doing great now! Thank You Dr. Gerdisch!"

"Dr. Gerdisch was detailed regarding the surgery and how I would feel afterwards; he is very personable. He took his time in our pre-surgery appointment and answered all our questions. There was only a seven centimeter cut through the sternum, not through the length of the sternum.

I was unbelievably pleased with recovery and the nursing team. They all kept pain to a minimum. Their goal was to keep pain at or near 3 on a scale of 1-10, with 10 being the worst. Pain was manageable; they never allowed it to get bad. I went into the surgery with a great deal of pain in my left foot from the results of long term rheumatoid arthritis. All through recovery the pain in my foot far exceeded the pain from the surgery. It would be impossible for me to recommend Dr. Gerdisch too highly."

"I feel vary privileged to have had such a talented surgeon. He and his team are true healers. As of to date I am back in action and looking forward to every day due to their dedication and care.

I would highly recommend any one with heart problems to seek out Dr. Marc Gerdisch and his outstanding team. Thank you for my second chance at life."

"Unlike any other operation that I have had, Dr Gerdisch explained the operation in easy to understand English that I understood what he was going to do, answered all my questions and I had many. He took the time to put my mind at ease. GREAT bedside manners. Once out of surgery and my family was able to see me they notice right away there was a change, my face wasn't bright red it was normal (flush tone). Now that I'm up and moving around and exercising I'm not struggling to take in oxygen.

I haven't felt this good in years. Sept 29 is my new BIRTHDAY. Thru GOD and GOD working thru Dr Gerdisch I could not imagine feeling this good . I would HIGHLY RECOMMEND Dr Gerdisch. Thank You Dr Gerdisch!!!!"

"Today, I celebrate my 69th birthday due to the skill of Dr. Gerdisch. God blessed this man with a humble nature and incredible skills and wisdom."

"Dr. Marc Gerdisch... You can look up all the facts and statistics, but what you can't find online is what an amazing human being this man is. When I needed open heart surgery to save my life, I was fortunate to have one of the worlds best in my own neighborhood. He and his entire staff made me feel comfortable the minute I met them. My mind was put at ease immediately. If you're not fortunate enough to live in Indianapolis, and need his expertise I highly recommend travelling here."

"Great!, fantastic, super. I was so glad I was lucky enough to have Dr. Gerdisch for my doctor. My surgery went fantastic, I feel so much better. Dr. Gerdisch was so good to explain what was going to happen. He made me feel like I was in good hands and I was. Bedside manners were awesome."

"I had aortic valve replacement surgery by Dr. Marc Gerdisch on August 8, 2014 with an excellent result. I experienced little to no discomfort during the post-operative period. Dr. Gerdisch was very professional and always willing to discuss my concerns and ask if I had any questions. There was always a person available by phone to help or direct you without the foolishness of an extended phone menu."

"Dr Gerdisch was not only a great surgeon but had a wonderful and friendly bedside manner. I owe him and the Lord my life."

"My experience with Dr. Marc Gerdisch was TOTALLY AWESOME from beginning to end. He is a human dynamo, while at the same time an humble and unassuming gentleman. He is eager to answer questions in understandable terms. He appears driven to treat his patients in the best possible manner. He has the admirable trait of giving credit for his success to his family, friends, patients and associates. Dr. Gerdisch has earned the utmost respect from his colleagues. He has a genuine smile which he uses often and effectively.

After Dr. Gerdisch accepted me as a patient, I had such a deep feeling that I was in good hands! From that moment on, I can say with no reservation, there was absolutely no trepidation. A calm peaceful feeling that remains with me to this day. I feel that God guides his every thought, diagnosis, decision, counsel with patients and his hands during surgery.

Dr. Gerdisch chose to repair my mitral valve. He explained exactly what he would be doing during my surgery. Everything went as planned! And my recovery has been better than expected and the scar is minimal."

"Everything was perfect from the pre-surgery through the post-surgery. Dr. Gerdisch and his team are like a well oiled machine.

My surgery was classified as high risk and I would recommend this man and his team to anyone needing heart surgery."

"Early this year, I found out that I was going to need a aortic valve replacement. I also had a ascending aortic aneurysm and some other thing to be fixed.

My heart doctor highly recommended Dr Gerdisch, though my family still wanted to do some research on other doctors and hospitals. In my 73 years, I've been very lucky and never had any kind of surgery before. Now, here I was looking at open heart surgery and it was scary. I didn't just want a good doctor, I wanted the best.

After all the research, we decided to go with Dr. Gerdisch.

Our first meeting with Dr. Gerdisch, he had us feeling 100% better about having the surgery. He has a great bedside manner. You can tell that he takes pride in what he does. He answered all of our questions and explained what he would be doing. We left his office feeling good.

My surgery was set up for May 14, 2014 at 7:30 AM. Everything went great. I never had any problems nor did I have the first bit of pain. I was out of the hospital in four days and four weeks later i was walking two miles.

Dr. Gerdisch and his staff did a great job. If any of the people I love would need any heart valve surgery I would want them in the hands of this doctor. Thank you Dr. Gerdisch for all you have done."

"Wow, everything went great! Five weeks out from surgery and I am feeling fairly normal now -- even with a setback of atrial fibrillation. Dr. Gerdisch and his staff were wonderful, very attentive to my needs. I highly recommend Dr. Gerdisch for this type of surgery."

"Dr. Gerdisch and his team performed my mitral valve surgery nearly 6 weeks ago. The entire team was wonderful to me from the initial meeting, through surgery, to post-op visits. Dr. Gerdisch was always engaging with me and my family and would listen to any concerns we had as well take time to answer questions. He was always friendly and comforting. I felt at ease with him and confident in his skills to perform my surgery.

I'm confident he not only extended my life but also is giving me an opportunity to have a higher quality of life. I can't thank him and his team enough. I highly recommend Dr. Gerdisch."

"Excellent experience. Marc is straight forward with explanations and takes the time required for full understanding of what is going to happen. Very personable."

"The mitral valve repair went very well and required very little time to recover. Dr. Gerdisch explained what was done and showed me pictures of the repair. I recommend Marc as a surgeon to anyone who needs heart surgery."

"Dr. Gerdisch has been very straight-forward with his comments, both before and after the surgery. His bedside manner has been such that this patient gained confidence in his ability to do the surgery.

It is my opinion that he has saved my life with two high risk heart surgeries, one performed in Nov 2008 and this last procedure done in Feb 2014. I am now being told that my heart is functioning at a level greater than before 2008.

I would recommend Dr. Gerdisch to any individual from around the world who is needing heart surgery or valve replacement. He is the best!"

"Dr. Gerdisch is not only an outstanding surgeon but he is a concerned and caring man as well. He performed surgery on a truly sick heart and remained dedicated to the healing of both the heart and the patient as well.

He was always honest about all aspects and expectations and provided all the answers to our questions and concerns with patience. His team was equally as forthright with their visits and gave us all a feeling of hopefulness and positivity for a full recovery during some worrisome moments.

He is a remarkable doctor and if ever anyone needs a heart procedure this Doctor is our choice. Trust is most important when facing the magnitude of heart surgery and if you choose Dr. Marc Gerdisch you are getting the best total care possible. Thank you from the entire Oliver family."

"I am very pleased with Dr. Gerdisch and his staff. They were very informative before my surgery, which put me at ease. They were also informative and helpful afterward -- which helped me prepare for my healing process and what to expect.

It has been 7 weeks since my surgery and I feel pretty good. I absolutely recommend Dr. Gerdisch for your heart valve needs!!!"

"I and my family feel that Dr Marc Gerdisch is one of the best heart surgeons in Indiana's history. We are very thankful to him and his staff for the thorough, skilled care we have received during this stressful time.

His follow-up, his bedside manner, his professionalism exceeds all standards and as a community we are very blessed. Thank you so much to Dr. Gerdisch and his wonderful, caring staff."

"Dr. Marc Gerdisch made such a difference in my life. Nine years ago I had an aortic valve replacement. The valve was leaking and deteriorating rapidly and I was advised that there was nothing further that could be done.

I had numerous issues as a result of the leaking valve, I was unable to walk any distance, had trouble breathing and sleeping and was told that due to my current health condition that I could not undergo further surgery.

I heard great things about Dr. Gerdisch and made an appointment to meet with him. After my first visit with Dr. Gerdisch he throughly and carefully explained in length what could be done, along with the risks that were involved. On January 22, 2014, Dr. Gerdisch replaced the aortic valve, the procedure went fantastic and was a miracle to me.

I came out of surgery feeling great and spent only four days in the hospital. I cannot thank Dr. Gerdisch enough for the new life which he has given to an 84 year old female!"

"I was amazed that this life and death situation went off so smoothly. Thanks Dr. Gerdisch!"

"Dr. Gerdisch was excellent in every way."

"I would highly recommend without reservation Dr. Gerdisch for any heart surgery. My surgery was extremely high risk. I had been declined surgery by two other surgeons. After meeting with Dr. Gerdisch and the confidence he exuded, my mind was put at ease that he was the man and that I had hope!

Nine months later I feel better than I have felt in five or six years and am so appreciative of his expertise. In three days, I will see my 62nd birthday which the other surgeons thought wouldn't happen. I am a survivor due to his superior talent and confidence and that of his staff!"

"I was very impressed with Dr Gerdisch's accomplishments and skills. His work, bedside manner and personality are all excellent and no one could ask for a better surgeon. My results are astounding."

"Dr. Gerdisch is a world-renowned heart surgeon whom I had complete trust in to do my Valve Repair and Bypass Surgery. A year later I feel better than I ever have. He is more than a great surgeon, he takes personal care in my well being. God blessed me with the best!"

"Dr. Gerdisch replaced my aortic valve and performed a full Maze procedure in February 2015. He was great in my pre-surgery consultation, while in the hospital and my 6 week check-up. I have complete confidence in his abilities. I am now 2 years post-op and am back to living a very active life."

"Dr. Gerdisch is a very accomplished surgeon and researcher, but he was also a very pleasant person--not always common in the type-A surgery ranks. He was patient in answering my questions, and it was clear that he had the skills and experience to handle my case. He performed a surgery that was complicated by two previous surgeries that had left significant scar tissue and damage. In pre-op visits as well as post op, he was always pleasant to talk to, and he put me at ease every time I saw him (he even did a mini-surgery in his office to remove a suture that poked through the skin during healing). I would recommend Dr. Gerdish to ANYONE in the Indianapolis area, and if I ever need another cutting I will try to get him to do it."

"Dr. Marc Gerdisch is the most wonderful and caring heart surgeon. I can say that because this was my 2nd heart surgery. Dr. Gerdisch and his staff treated me and my family like family. He truly has a great love for what he does and his patients. Thank you Dr. Gerdisch for making my life better."

"Dr. Gerdisch took the time to answer my many many questions. He explain what needed to be done and why and how. After that visit I knew I was in the best of care. I have been doing great since that surgery."

"As I approach the one year anniversary of my surgery to repair a diseased aortic valve I am reminded of a number of things. The first is that I am blest with each new day and thankful to God for the ongoing enjoyment of life. Along the way however, from the very first realization that I had a problem, to the understanding of the extent of the damage to my valve, to replacing the valve, to today when I feel so blessed, there are many who have contributed to the success.

Chief among those would be Dr. Marc Gerdisch and his team for the fine job on removing my damaged aortic valve and replacing it with the On-X valve. The great surgical skill that was displayed during the surgery, further evidenced during my recovery and the manner which my incision has healed are evidence of the great care taken throughout the procedure. The healing of my incision has left me with essentially no lingering effects, neither physical nor cosmetic. For this I am very thankful.

The skill of Dr. Gerdisch was not relegated to surgery alone. The pre and post operative care was just that, concerned care. Dr. Gerdisch is a care giver fully aware of the trust that I sought in my surgeon at such a critical time when life seemed so frail and fragile. That trust was never violated and has only grown as my vitality has increased. This entire experience bodes well for an active life for many years.

The caring spirit of Dr. Gerdisch would have been welcome anywhere. However, as a part of the excellent care and service, the expression of competence and care I received was seamless. A totally curative environment and experience."

"Dr. Marc Gerdisch's bedside manner was impeccable. All of my questions were answered before and after my mitral valve repair.

I haven't felt this healthy in 15 years! I feel youthful and energetic. I feel like I have my life back but even better than before."

"It's been 5 years since Dr. Marc Gerdisch replaced my mitral valve. I am doing super! Feeling better than I have for years... Thank you doc!!"

"On November 7, 2009, I became one of Dr. Gerdisch's patients. Dr. Gerdisch evaluated me and immediately realized that unless I had immediate surgical intervention that my life was at great risk. I had no idea that I was in atrial fibrillation and heart failure. On November 9, Dr. Gerdisch repaired my mitral valve, replaced my aortic valve and performed the Maze procedure. I know that Dr. Gerdisch through his training, expertise, talent, concern and compassion saved my life. Dr. Gerdisch also cared for my family both pre and post operation in that he patiently explained the surgical procedure to them, answered their many questions, and reported to them immediately after the operation concluded. My operation has been a complete success and my family and I will be forever grateful."

"I recently dropped off one of the first copies of a book that I have just written at Dr. Gerdisch's office. In it I wrote a very simple yet heartfelt expression of appreciation: "Thank you for saving my life." I had walked around for a few weeks wondering if my next step would be my last and learned later that in fact I would have died in a very short period of time had the surgery not been performed. My experience was excellent in all respects without exception.

Dr. Marc Gerdisch is a very special person. He is at the absolute peak of his profession and has an exceptional ability to relate to his patients and to others. While I was in the hospital post surgery a great many persons expressed to me how talented they thought he was. I later learned that Dr. Gerdisch is a world renowned heart surgeon who in addition to performing surgeries travels extensively worldwide to lecture and train other heart surgeons. He has been in the forefront and a pioneer in developing new concepts and new techniques. He is the current President of the 21st Century Cardiothoracic Surgical Society which is an organization of the leading heart surgeons in the world. Membership is limited to 65 surgeons.

I am still an athlete and compete with and against much younger athletes playing full court basketball. Following surgery I was restricted from playing for a period of 13 weeks. When that recovery period ended I went back to playing the next day and had no difficulty doing so. I was able to return quickly because of the condition I was in prior to surgery and the effort I had put into rehabilitation. I should also note that I was released from the hospital in four days, which my cardiologist described as "absolutely amazing." I am commenting on this not to pat myself on the back but to give encouragement to others. The book that I have written is entitled "Racing the Wind; Seventy-seven and Still Playing Full-Court, Fast-Break Basketball: Achieving Athletic Longevity, A Gift That Keeps on Giving." A vignette in the book describes my experience as an open heart surgery patient in more detail.

Again I would like to express my sincere gratitude to Dr. Gerdisch."

"Dr. Marc Gerdisch was an amazingly gifted surgeon. Doctor Gerdisch was able to not only explain to me what valve I needed but also got my insurance company to understand the new valves. He actually gave me his personal cell number while I was fighting with the insurance company. Doctor Gerdisch saved my life and got me back to my normal life."
