"Great surgeon. He was able to repair my mitral valve instead of replacing it. This was no easy task considering how badly my valve was damaged. Doctor Gang and his team visited me every day and answered all my questions. They were very kind and caring. It has been three weeks since my surgery and I feel great. "
-- David Merrrick, Mitral Valve, Valve Repair, 11/20/2019
"Dr. Gang was excellent!! A "5-Star" procedure!!!"
-- jack burke, Mitral Valve, Valve Replacement, 10/21/2019
"Dr. Gang saved my life! I was not worried about the procedure at all. His skills are amazing and he checked on me - even during the weekend. His team works like a well oiled machine."
-- Jasen Beymer, Mitral Valve, Valve Repair, 09/17/2019
"I was very pleased with Dr. Gang, PA Casey and the entire surgical team. I was well-informed prior to and after surgery and my hospital care was excellent."
-- Norman Niedergang, Aortic Valve, Valve Replacement, 09/11/2019
"I had known for some time that I needed to have this surgery but, I was unsure of where and who was going to perform it. I made an appointment to see Dr. Gang and was surprised at how soon I could see him. I had done my homework, reading his qualifications and reviews and had made a list of questions for him.
When my wife and I first met him we were both impressed at how he listened to my account of my medical condition. He was so patient and didn't seem to be in a hurry to see his next patient. His experience with the type of surgery I needed was comforting. Finally my wife asked if he would be willing to do my surgery, and he said, "Certainly". He explained the risks, and proceeded to answer all my questions. I actually felt relieved that I had found the right surgeon.
After the successful surgery, he saw me every day and his bedside manner was so calming, I felt he really cared about me as a person and not just another patient. Dr. Gang and his team always included me in my treatment, keeping me informed. I am home and recuperating now, looking forward to the future. I forgot to mention I am 73 years old. I would highly recommend Dr. Gang as my surgeon and my wife and I are glad that we chose him and his service."
-- Richard Cosco, Tricuspid Valve, Valve Repair, 08/19/2019
"My entire experience from beginning to end was incredible. From the first meeting with Dr.Gang I knew he was the surgeon for me, he was confident, calm & informative. The surgery itself went perfectly, he was prepared, and even though my repair surgery was more complicated than most, he fixed my broken heart. After the surgery he was there explaining things and checking on me, and encouraging me to begin my recovery, which has gone better than anyone could have expected. I was up walking that day, and am almost ready to return to my normal life 2 weeks out. Gratefully, Dawn Aldaz"
-- Dawn Aldaz, Mitral Valve, Valve Repair, 08/14/2019
"After researching all the thoracic surgeons and hospitals in the area, my family and I felt confident with the team of Dr. Gang and Dr. Tomasko at Central Dupage Hospital in Winfield. The doctor ordered all the pre-tests and we felt that he was prepared to discuss the results with us in great detail, but that we could easliy understand, at my first consultation, and we never felt like we were rushed, as we had many questions during this appointment. It was easy to schedule the surgery date, the doctor was very flexible with my crazy schedule. The day of surgery, the entire team took great care of me, prior to, during and after surgery and my family with frequent updates during the procedure. Each day post-op I was visited by one of the many cardiologists or surgeons in the group to check on my status and answer any questions I may have had. I only needed 2 post-op appointments with the surgeon, to see how I was doing, check my incision site, and provided feedback to my questions and/or concerns. In the event of any cardiac event in the future, I would hope that this team would be on call, or available to take care of me, but I feel I have learned enough from them to make the appropriate changes in my life that I would prevent me from crossing this path anytime in the future."
-- CHeryl Taylor, Mitral Valve, Valve Repair, 07/02/2019
"Dr. Gang was extremely professional throughout the entire process from diagnosis to surgery to after surgery follows-up. He explained my valve issues and the required surgical procedures clearly. He also described my expected after surgery results and long term benefits of the procedure. Dr. Gang and his team at Central DuPage Hospital were exceptional in both the surgery and after surgery care in ICU. My recovery time period has exceeded my expectations and I am well on my way to return to the golf course and bike riding. I highly recommend Dr. Gang and Central DuPage Hospital."
-- robert settles, Aortic Valve, Mitral Valve, Tricuspid Valve, Valve Repair, Valve Replacement, 06/26/2019
"Dr. Gang is the best cardiac surgeon in Chicago-land. He and his team performed a life-saving procedure on me that replaced my calcified bicuspid aortic valve and at the same time repaired an aneurysm in my aorta. I owe my life to him and his excellent team. The results of the surgery were nothing short of perfection. I really did not experience much pain or discomfort after the surgery. I was off of pain medication within 2 days of the procedure. Dr. Gang's bedside manner is the best and I always felt safe in his hands throughout the procedure and post op, If I had this to do over again I would definitely pick Dr. Gang to do it and I would highly recommend him to anyone facing heart surgery. "
-- Raymond Feld, Aortic Valve, Valve Replacement, Root Replacement, 06/18/2019
"As a senior, I have experienced those that produce shoddy, incomplete or must do over work, and have found many that produce good work. Then there are the masters of their craft, Dr. Gang is a master. He performed four surgeries in ‘one’ on me. A Maze procedure, replaced the Aortic valve and repaired the Bicuspid & Tricuspid valves. In addition to his talent, he is a caring, compassionate man, and checked in every day after surgery. After a few weeks, I am back to everyday activities. Thank You Dr. Gang for extending my life!"
-- Jim F, Aortic Valve, Mitral Valve, Tricuspid Valve, Valve Repair, Valve Replacement, Maze Procedure, 06/17/2019
"Dr. Gang and his group are fantastic. He discussed and helped me choose the right valve for me. He is a great surgeon-my incision is smaller than expected and healing very well and I happily did not require blood transfusions. Recovery is going extremely well and I am thankful everyday that he was my surgeon."
-- Heidi Rockwood, Aortic Valve, Valve Replacement, Median Sternotomy, Bloodless Surgery, 06/05/2019
"Dr. Gang was PERFECT! Couldn’t be happier. Would highly recommend Dr. Gang."
-- Kenneth Niemeyer , Aortic Valve, Valve Replacement, Maze Procedure, 05/24/2019
"From my introductory visit, through pre-op and post-op, I never felt in better hands than with Dr. Gang and his team. The initial visit with Dr. Gang put my wife at ease and validated my research that he was the surgeon to conduct my Aortic Valve Replacement and to repair the aneurism on my aorta. The entire process with Dr. Gang and his team was a well conducted symphony with everything in harmony. Every step of the process was well coordinated, professional and executed with precision and accuracy. My operation took approximately 3.75 hours, I was out of intensive care within 24 hours, was walking within 48 hours and I was back home within 4 days to start my recovery. During this time Dr. Gang exhibited an outstanding bedside demeanor as did his staff and associates. I could have not have been more pleased with Dr. Gang and the outstanding results that he delivered. In short, Dr. Gang, his team and associates can best be describes as "Best-in-Class." I owe him and his team a better and extended life. Should I ever need any similar surgery in the future, he is my guy!"
-- Gary Gadzinski, Aortic Valve, Valve Replacement, 05/15/2019
"On May 14, 2019, I had my aortic valve replaced as well as having my heart muscle trimmed. On July 23rd, I hiked in the mountains of Colorado to 12,848 feet. It was great! I could not have done it before the surgery. Dr. Gang was great with a very positive outcome."
-- Stanley Grismore, Aortic Valve, Valve Replacement, 05/14/2019

-- Thonas Rimac, Aortic Valve, Valve Replacement, 03/12/2019
"Dr. Gang is an incredible surgeon. I interviewed a couple of different surgeons and Dr. Gang above all was the best. He explains everything that is going to happen before the procedure. During the surgery and after the surgery he makes you feel like he is part of your family and really cares about you.
My procedure went well and by week 4 I was driving, no pain meds and started rehab to get back to exercising.
Dr Gang his staff and Central DuPage/ Northwestern Hospital are the best. Thank to Dr. Gang , his staff and the Hospital. "
-- Carole Feigley, Aortic Valve, Valve Replacement, 02/25/2019

"Dr. Gang's bedside manner was great. He and his staff listened well and answered all questions I had. The surgery was on a Tuesday and was home by Friday. I was able to go back to work part-time at 6 weeks post-surgery and will be full-time at 8 weeks post-surgery."
-- Laura Oscarson, Mitral Valve, Valve Repair, 01/15/2019
"Easy to talk with. A calming influence in the face of significant surgery. The entire team works very smoothly. The operation was very successful as well as mostly pretty comfortable. Granted they opened my chest but my knee operations were more “noticeable “ than my valve replacement has been. Thanks to all!"
-- David Altekruse, Aortic Valve, Valve Replacement, 01/04/2019
"I would truly recommend Dr. Gang to any and everyone that would need heart surgery. Dr. Gang gave my wife and I an explanation for what was going to be done during the surgery in terms we could easily understand. He took the time to answer all of our questions. Dr. Gang made gave me 110% of his knowledge and abilities. His bedside manner is phenomenal. Again, explained everything and answered every question. I am very happy with the results of my surgery. "
-- Dan Polka, Aortic Valve, Valve Replacement, Root Replacement, 12/17/2018
"Dr Gang "fixed the unfixable". My bicuspid aorta had deteriorated to the point where he said that he didn't know how I walked in. He is my hero!"
-- Charles Libby, Aortic Valve, Valve Replacement, 12/12/2018
"Dr. Gyu Gang and his staff have been amazing. They have been wonderful at addressing all questions and concerns. He replaced my aorta, fixed an aneurysm and performed a double bypass. Had it been a week later there is a very good chance I wouldn't be here. I could not have had a better experience."
-- Charles Libby, Aortic Valve, Valve Replacement, 12/12/2018
"Dr. Gang made a welcoming and comforting presentation, on how he would do his procedure / tasks. Then, with good follow up visits, (including a drainage on lung), he & his team of service providers helped me feel good again so I can return to employer and live on!"
-- william degorski, Aortic Valve, Valve Replacement, 11/19/2018
"Finding Dr. Gang was a blessing. I immediately realized he was an excellent surgeon. His intelligence, expertise and confidence made it an easy decision to proceed with valve replacement surgery. He explained everything that would happen. His positive attitude and vast experience gave me the peace of mind I needed. I trusted him with my life and he delivered by performing perfect surgery. He followed up afterwards with attention and care. He has the best job in the world... saving and extending lives! I am forever in his debt. I would recommend Dr. Gang to anyone needing valve replacement. You can look far and wide but you will not find a better surgeon than he is. I could never give him enough thanks and praise. He truly is the best!"
-- William Sebestik, Aortic Valve, Valve Replacement, 11/13/2018
"I knew the first time I met with Dr. Gang that he was the surgeon I wanted. I had a level 4 (very bad) leaking mitral valve. He is such a highly skilled and well trained surgeon. Northwestern is very lucky to have him. My surgery was open-heart. He was very good at explaining what he was going to do. My recovery went very well. My wife and I knew I was in the right hands. My surgery was on a Friday. He came to visit me on Saturday and Sunday. I was able to go home on Monday. I love Dr. Gang. So does my whole family."
-- Allan Stover, Mitral Valve, Valve Repair, 11/09/2018
"He is a great surgeon and his staff are wonderful. They will take all the time in the world to listen and answer your questions. The ICU staff is wonderful."
-- kim Jacobs, Aortic Valve, Valve Replacement, 10/16/2018
"My stepdad was the patient, but with our very first visit with Dr. Gang I was confident we had the right doctor. He was nothing but informative and reassuring through the whole process, I was more impressed with the many times he checked on my Dad in ICU the day of and next day after surgery. He was nothing but attentive."
-- Tracy Feece, Aortic Valve, Valve Replacement, 09/25/2018
"Dr. Gang was always very professional, yet personable. The surgery was performed in the amount of time that had been estimated without any complications. The results have been great and I've been recovering faster than expected. Follow up with Dr. Gang after the surgery was very positive and helpful. He's been available when we need him to be and ensures we understand everything we need to know. I would definitely recommend Dr. Gang to anybody in need of a valve replacement and most likely any other heart surgery."
-- Dennis O'Malley, Aortic Valve, Valve Replacement, 09/14/2018
"I interviewed Dr. Gang previous to my surgery and found him to be not only extremely knowledgeable regarding what I needed done (Mitral valve and Aortic valve replacement as well as a double bypass of the Right Coronary artery - 100% blocked and Left Descending Coronary artery -90% blocked) but also found he is very experienced in successfully performing surgery to fix these complicated problems.
He was very reassuring as to what the positive result would be which gave me the needed confidence to move forward. He has a good sense of humor and friendly manner that immediately put my wife and I at ease and coupled with his extensive positive track record and technical expertise, I willingly put my life into his very capable hands. The operation was a success and while recovering has it's ups and downs I was able to contact or meet with him and his very capable staff at any time to ensure I was on the right path and healing properly.
I highly recommend Dr. Gang and his staff for this type of complicated life saving surgery and gladly state that I am living proof of his formidable capabilities in this area of medicine."
-- Roger Harmon, Aortic Valve, Mitral Valve, Valve Replacement, 09/05/2018
"Dr. Gang is an exceptionally skilled surgeon with a knack for putting patients and family at ease. He answers all questions thoroughly and completely and explains all expected outcomes or potential complications. Both pre and post surgery visits were very helpful. I highly recommend him for any heart surgery... In fact, I wouldn't recommend anyone else."
-- Steve Bosak, Mitral Valve, Valve Replacement, 08/29/2018

"From the moment I met Dr. Gyu Gang I felt at peace with his smile and ease of surgical explanation. He reassured me that all was good, nothing to worry about and that he would take excellent care of me. The surgery went well indeed and I was very blessed to have Dr. Gang as my surgeon.
His nurse Morgan was so amazing. She was there from the beginning of surgery, ICU, cardio ward, and my first office follow up visit. Everyone in the office was so professional and supportive during this emotional time.
Dr. Gang showed me confidence and trust needed to get through this surgery. I would highly recommend him to anyone considering heart surgery. He is the absolute best and has an outstanding support staff!"
-- Jeffrey Mallory, Aortic Valve, Valve Replacement, Root Replacement, 06/20/2018
"On June 6,2018, Dr Gang and his team performed a highly successful open heart surgery to repair the mitral valve and provide two by-passes for my heart. Dr. Gang is very professional and has excellent skills.
I feel great , and Dr Gang released me from his care on June 28th. Dr. Gang's operation and recovery procedures really exceeded my expections .He deserves the highest 5 STAR rating.
I highly recommend Dr Gang for open heart surgery."
-- David Opferman, Mitral Valve, Valve Repair, 06/06/2018
"Dr. Gang did an outstanding job. He was very professional and encouraging, did a remarkably fast surgery and during our first checkup was very encouraging. His confidence is high and he backs it up with a 100 percent great job. I would always recommend him in the future. His staff also did a wonderful job in every area."

-- Leonard Kelleher, Aortic Valve, Valve Replacement, Median Sternotomy, 05/21/2018
"Dr. Gang is very caring and thorough in describing the high risk surgery with me and my friends and family. He visited me at least once every day I was in the ICU and cardiac hospital floor. He performed this very specialized valve repair using my own tissue so I did not face rejection and let me know regularly how well I came through the procedure. I would recommend his expertise to anyone needing a heart surgeon."
-- Marcia Early, Tricuspid Valve, Valve Repair, Median Sternotomy, 05/01/2018
"There couldn't be a more caring, concerned surgeon than Dr. Gang. He explained my procedures thoroughly and answered every question I had. Thanks to his expertise, my recovery is without complications."
-- Jayne Hoalt, Aortic Valve, Valve Replacement, 04/06/2018
"Dr Gang clearly had read my file in detail before meeting me for the first time. He is an excellent listener and responded to all questions in detail - from all of my family. He explained things in terms that everyone understood and took as much time as was necessary to satisfy everyone, showing diagrams and imaging to help demonstrate the need for the surgery. He gave me great confidence that I was in good hands and he gave me the impression that I was his most important patient. I have no hesitation in recommending Dr Gang to anyone considering open heart surgery."
-- Edward Jacob, Aortic Valve, Valve Replacement, 03/23/2018
"Dr. Gang is the best if not one of the best in this field. Hearing that I'll will have an open heart triple bypass surgery was like "end of the world" scenario for me at first. But after Dr. Gang talked to me and my wife and explain/answer every questions we have about the procedure, we know we have the right Dr. His whole team is exceptional. From the office secretary to every member of his staff. His bedside manner is very professional but at the same time personal with the patient. He listen and attends to the patient's needs and concern. Now, 4 weeks after surgery, I'm brisk walking the treadmill for 30 minutes daily and pretty much getting ready to be back to my "normal" daily routines. Getting better each day. If you need surgery concerning your heart, you can never go wrong with Dr. Gyu I. Gang and his team at Northwestern Medicine. Highly recommended."

-- Julia/Ronald Hoppe, Aortic Valve, Valve Replacement, 02/19/2018
"Dr. Gang is the only doctor I would recommend for any issue with your heart. Dr. Gang was compassionate knowing how I feared any surgery. He took his time to explain the procedure and after I saw other doctors I knew that I would be in the best hands possible with Dr. Gang.
And, of course most of us know that Northwestern is "tops" in many fields of medicine including heart issues. Besides Dr. Gang's skilled hands he has a support staff that is always available for any questions or concerns.
Dr. Gang's nurse Morgan certainly helped me through a most stressful and scary time and like any "business" the "boss" has to have a great support staff, many doctors do not have a great support staff and believe me the support staff is VERY important especially during recovery.
The medical world is blessed to have Dr. Gang!"
-- Betty Loren Maltese, Aortic Valve, Mitral Valve, Valve Replacement, 02/06/2018
"Dr. Gang is an EXCELLENT surgeon. He explained the procedure to me in detail. I had every confidence in him. I had the Aortic Valve replaced and he repaired the Mitral Valve. I am extremely pleased with the result. You will be in good hands if Dr. Gang is your Heart Surgeon. "
-- Robert Cardinell, Aortic Valve, Mitral Valve, Valve Repair, Valve Replacement, 02/05/2018
"My surgery went amazing due to Dr. Gang and his wonderful caring team. He has a caring heart so I can't imagine why all his heart patients wouldn't heal quick! He cares more than I have ever seen a doctor care about his patients--and I do know I'm his favorite!!!"
-- Toni Young, Mitral Valve, Valve Repair, 01/09/2018
"I came to Dr. Gang after finding out that I needed another valve surgery. He and his staff were great right from the start. He recommended a mechanical valve which I completely agreed with, since the tissue valve I had done had failed 3 years ago. My surgery went really well and the nursing staff had me up and walking the next day! Dr. Gang, Whitney and Morgan stopped by every day during recover to see how I was doing. The nursing staff at the hospital were exceptional. I felt so much better after surgery than the first time I had it done which was pretty rough. I want to thank Dr. Gang, Whitney and Morgan for their top rate care and professionalism. I will definitely recommend them to anybody I meet who needs any heart surgery."
-- John Baker, Aortic Valve, Valve Replacement, 12/28/2017
"Dr. Gang is a fantastic doctor and surgeon. He is extremely down to earth and humble, with a bedside manner second to none. Additionally he is an extremely nice man. There were a few surprises with my surgery, especially with the aortic valve replacement, which was actually a re-replacement. He came to see me every day I was in the hospital, which was for 10 days. His concern for me and my wife were very genuine and much appreciated. Too often cardio vascular surgeons lose sight of whose important in the whole scheme of things. Dr. Gang did not. He was very detailed about the surprises that came up during my surgery, along with a very genuine concern for me, the patient. I can't imagine going through what I did with anyone but Dr. Gang. I would, without hesitation, recommend him to anyone who is looking at any kind of heart valve surgery. They won't find anyone better."
-- Bill Kalnes, Aortic Valve, Mitral Valve, Valve Replacement, 10/17/2017
"Dr. Gang turned what could have been a life threatening experience into an unbelievable life change. I can’t thank him enough."
-- Peter Kollias, Aortic Valve, Valve Replacement, 09/23/2017
"Dr. Gang is a wonderful and attentive surgeon. He is the reason I am able to write this recommendation today. When I first met Dr. Gang, I was frightened by the prospect of open heart surgery. Dr. Gang clearly explained to me what was wrong(in fact it was the clearest explanation I had ever received) as well as the treatment plan. He was by my sided when I came in for surgery and continually checked on me after the operation. Dr. Gang is a compassionate surgeon and is the reason I have a new lease on life!"
-- David Magee, Aortic Valve, Valve Replacement, Root Replacement, 09/20/2017
"I would first like to say that Dr. Gang saved my life. So for that I will always be grateful! He was extremely knowledgeable, thorough in explaining my surgery and took his time explaining any questions I had. I recommend him for a heart surgeon, you will be in great hands."
-- Christina Kowalczyk, Aortic Valve, Valve Replacement, 09/19/2017
"Dr. Gang and his team are awesome! I can honestly say that I was nervous at first not knowing what to expect, Dr. Gang made me very comfortable, was very informative, and answered and all my questions. I wouldn’t hesitate for a moment to recommend Dr. Gang! He is truly a great surgeon supported by a great group of highly skilled and professional nurses."
-- Margaret Lunquist, Mitral Valve, Valve Repair, 09/18/2017
"Dr. Gyu Gang did a fantastic job. I have several medical issues and he spent a considerable amount of time discussing my concerns and how we were going to get through a challenging surgery. Dr. Gang was with me every step of the way and I'm doing great. "
-- Deborah Walton, Mitral Valve, Valve Repair, 12/20/2011
"Like most surgeons, Dr. Gang was brisk but took all of the time necessary to answer my questions both pre and post op. The surgery was flawless and I was out of the hospital in three days and am back to running my 7 miles daily."
-- Patrick Miller, Aortic Valve, Valve Replacement, 11/10/2010
"Dr. Gang has performed hundreds of valve replacements and the only reason he has not yet done thousands is that he's young. He is a good listener and very well versed in the range of surgical and valve options. He did not hesitate to recommend a tissue valve for me. He stressed the need for a patient to shop around and feel comfortable with their surgeon - as a "sacred trust" is required. He also stressed that if I were to have any complications or issues that he "doesn't run" and he's fully responsible, accountable and owns up to his work. His office staff was swift and efficient with my short term medical leave paperwork. He is very confident and reassuring. Lastly, he also suspects I will outlive my valve and said he uses certain techniques to make it easier for the next valve replacement. "
