Patient Review of Dr. T. Sloane Guy

"I read that Dr. Guy was one of the best robotic heart surgeons in the country. It made the most sense for us to make the trip back down from Minnesota, and it was definitely worth it. Just two days after the surgery, I was leaving the hospital and feeling great. I can’t believe what the team was able to do through these tiny incisions. I remember when my brother had open heart surgery, and this is a totally different experience."

-- Bill Mayfield, heart valve surgery patient

"I had a mitral valve repair and cardiac ablation performed by Dr. Guy eight weeks ago.

I had been experiencing prolonged episodes of palpitations on any given day for many years, that were negatively affecting my life. In short, they were driving me crazy. When they occurred, I didn’t feel well.

I’m a doctor and after hearing about Dr. Guy, I did my research. Among other things, I listened to his lectures to other cardiothoracic surgeons on the Internet, and was impressed. I came to realize that he is one of the best in the world at performing robotic mitral valve surgery. I had consultations with several different doctors who practice in the area in which I live, but after speaking with Dr. Guy on a video consultation, I knew he was the one that was going to perform the surgery. He was very confident and concise. He spent a lot of time with me explaining the procedure and answering my questions.

I flew from Pennsylvania to Georgia for surgery in August 2023. I was discharged from the hospital several days post op . At two weeks post op, I was back in the gym lifting weights, taking it easy of course. At eight weeks post op, I feel great. The troublesome palpitations are gone and I feel better than I have in years. I’m in the gym 1 1/2 hours a day, three days a week with no limitations.

Dr. Guy is a brilliant, caring surgeon with a great personality, and an amazing staff. I would highly recommend him to anyone in need of mitral valve surgery."
