Dr. Geirsson

"Excellent experience. Dr Geirsson had a great bedside manner. I felt very comfortable at our first meeting. He answered all my questions. All of the doctors and nurses on the Cardiac floor were great!

With regard to my procedure, I had non-invasive Robotic Surgery on Tuesday December 20th and was able to go home 2 days later. After my first night home, I was able to transition to Extra Strength Tylenol, only, for pain management.

It's unbelievable that you can have open heart surgery and be home 2 days later. I feel great and expect to be back to work in less than 2 weeks from my surgery date.

Dr Geirsson is the man! I highly recommend him."

"I was diagnosed with mitral regurgitation many years ago. So, I had been in “watchful waiting” for quite some time. When I became symptomatic with water retention, shortness of breath and fatigue, I knew it was time for surgery. As a 52-year-old single mom of teenage twins, I was nervous. At times, I was terrified. For those reasons, I did A LOT of research about my treatment options. I also met with several doctors.

Thankfully, I connected with Dr. Geirsson at Yale New Haven Hospital. Doctor Geirsson helped me understand the benefits of getting a mitral valve repair (with a ring) compared to a mitral valve replacement. Plus, Dr. Geirsson was the only surgeon in my area who was trained in minimally invasive, robotic-assisted mitral valve repair techniques.

The surgery was a complete success!!! I had very little pain. In fact, I was off pain medications on the third day. I was only in the hospital for four days. I entered the hospital on Tuesday and was discharged on Friday. I was driving just one week after surgery. Most importantly, I feel so much better and I have so much more energy. My family and friends could not believe that I had heart surgery.

Many thanks to Dr. Geirsson and his awesome team at Yale New Haven Hospital!"
