I wrote an extensive review of Dr. Guy and his fabulous after care staff, especially the ICU unit. I could not have been in better hands for my 5 day stay. He should be considered the top 2 Robotic heart surgeons in NYC, and I am living proof of his mastery. The entire process of surgery had intelligent, competent and moreover friendly professionals attending my new experience, putting me at ease. I am out of the hospital recovering at home, and I'm feeling better every day.

Great doc. I'd trust him with my life (again). Just a plain old good guy who seems to genuinely care about his patients. Never once got the feeling he had somewhere else he'd rather be.

In a word, Doctor Guy is awesome! He is careful, smart, skilled, experienced and an exceptionally nice person.
in New York, NY |
Dr. Guy is a surgeon of consummate skill, and equally importantly, an accessible, truly nice person. He performed a difficult mitral valve repair using robotically assisted minimally invasive methods, and my surgical experience, hospitalization and outcome could not have been better. He is new to New York City and we are extremely fortunate to have him here.

I had researched the best possible alternatives for Mitral Valve repair and Dr Guy and Weill Cornell came out the best choice for me . His skill in Minimally Invasive Robotic Surgery , his experience as a Field surgeon for the US Military were the major factors that made me consider him first for as the best surgeon for my repair procedure . The team he has surrounded himself were equally impressive .

A Doctor who is courteous, knowledgeable in his field, articulate and one who truly cares about his patients well being. He explains in detail so nothing is done without my full understanding of the health issues, risks and the outcomes of surgery. He is easy to talk to and is an extremely competent Heart Specialist. Further, the staff is professional and courteous. I would recommend him to friends and family.
in Lebanon, NJ |
Dr Guy and his team are the ideal staff to work with. I have no doubt that Dr Guy could have handled any unforeseen development They will explain everything and take as much time as you need. No rushing to get to the next patient. You feel like one of the family . Everyone is so very friendly. They focus on being minimally invasive and then pain management. The process of tests and admittance was fast and seamless. Then the nurses attending to you could not be better.
in Ann Arbor, MI |
Dr. Guy has superior expertise and skill in thoracic surgery. He performed my triple bypass operation very beautifully with a great success. I was treated me exceptionally well. He very nicely and respectfully responded to quite a few questions from my family and me. He also made a special effort to help us find a facility where I could stay after discharge. I will certainly recommend him to my family members, friends, and others without any hesitation, when they need a thoracic surgery.

Dr. Guy's Care Philosophy

As a cardiovascular surgeon, my goal is to help my patients and their families with cardiac disease requiring surgery with a high level of commitment and quality.

Dr. Guy says...

My primary focus is on the treatment of mitral valve disease using the latest minimally invasive and robotic techniques.  I also specialize in the treatment of hypertrophic cardiomyopathy, aortic valve disease, aortic aneurysms, surgery for heart failure, and many others.  As a specialist in the treatment of mitral valve disease, I repair a very high percentage of the valves I operate on and in most patients, perform the procedure endoscopically with robotic assistance.  I also have experience with catheter-based treatments for mitral valve conditions.

Dr. Guy says...

I perform totally endoscopic robotic mitral valve repair on a routine basis.  I also have experience with catheter-based techniques to treat mitral valve conditions.  I also perform minimally invasive surgery for the aortic valve and have experience wtih TAVR (transcatheter aortic valve replacement).  Additionally, I have performed a high volume of standard cardiac surgery procedures including aortic aneurysm surgery, aortic dissection, heart transplant, ventricular assist devices, the total artificial heart, and many others.  I have a great deal of experience performed redo heart surgery (heart surgery in patients who have had previous heart surgery).
