Hello! My name is Dr. Marc Gerdisch and I am a cardiac surgeon having graduated from Loyola University Stritch School of Medicine in 1987. To date, I have performed approximately 5,000 cardiac surgeries, of which 3,750 involved heart valve procedures. I regularly perform surgery at hospitals including Franciscan St. Francis Health Heart Center and Franciscan St. Francis Health Heart Valve Center. Read more...
I believe my greatest strength is my relationships with my partners, associates, staff and patients. During the past several years, my practice has become 90% valve surgery. I have developed a specialized set of operative skills that allow me to reconstruct the heart. My creativity coupled with an understanding of the inter-dependence of the heart structures has directed my unique experience as an individual surgeon. Returning someone to their life is an incredible experience that I share with my entire team and the patient. Perhaps beyond my surgical expertise, my greatest strength is my central role in developing a program with a pervasive theme of excellence in the diagnosis and treatment of heart valve disease. I have the luxury and my patients have the benefit, of being part of a process based on excellent communication and partnership among some of the finest health care professionals working in cardiac care. My practice spans from minimally invasive valve procedures to complex multi-valve operations in patients with advanced disease. Preserving and restoring cardiac architecture and function is my highest priority. I have had the good fortune to participate in trials and research that have enhanced our ability to achieve these goals. We currently have studies on-going with next generation heart valves, treatment of atrial fibrillation and the use of extra-cellular matrix (ECM) in tissue reconstruction. In 2007, we were the first in the world to use the ECM bio-scaffold to rebuild or replace cardiac tissue and in 2008 we performed the first operations using ECM in patients with valve disease. In the lab, we are evaluating mechanisms for cardiac tissue re-growth that we hope will have a profound impact on the future. My team and I deliver the care we would want for our own family. Our patients know our commitment, and our greatest reward is their health and life-long friendship.

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!"
-- Brian Brown, Aortic Valve, Valve Replacement, 04/28/2016
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."
-- Jack Newman, Mitral Valve, Tricuspid Valve, Valve Repair, Maze Procedure, 04/18/2016
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! "

-- Dwight Rice, Mitral Valve, Valve Repair, Robotic Surgery, 07/30/2015
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. The other advantage that Dr. Gerdisch has and offers is Franciscan St. Francis hospital in Indianapolis. I had, by far, the best treatment of any place that I am familiar with.
All told, you couldn't be in better hands."
-- Jay Siegel, Mitral Valve, Valve Repair, 07/17/2015
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."
-- Jeffrey Roberson, Aortic Valve, Valve Replacement, 07/13/2015
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! "

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."
-- Ethan Luo, Mitral Valve, Valve Repair, 06/19/2015
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 hospital and surgeon, I felt a strong appreciation of the Franciscan St. Francis Hospital surgical care model, their ranking as one of the top hospitals for cardiac care nationally, and the 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-surgergical 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. "

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!!!"

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."

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 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."

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."
-- RICHARD PERKINS, Mitral Valve, Valve Repair, 06/13/2014
My surgery was classified as high risk and I would recommend this man and his team to anyone needing heart surgery."
-- charles grubbs, Aortic Valve, Valve Replacement, 06/09/2014
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 at St. Francis Hospital in Indianapolis, Indiana.
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."

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!"
-- Dwight Armitage, Mitral Valve, Valve Replacement, 02/22/2014
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."

-- Connie Hicks, Mitral Valve, Valve Replacement, Median Sternotomy, Maze Procedure, 01/27/2014
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!"

Chief among those would be Dr. Marc Gerdisch of Franciscan St. Francis Health 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 of the Franciscan St. Francis Heart Center, the expression of competence and care I received was seamless. A totally curative environment and experience. "

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."
