I too have a leaking mitral valve after 15 years. I was 55 at the time, I am now 70 years old, I am active, walk from 10-15 miles a week, can do aerobics, dance, etc. My repair was by Davinci robotic surgery, 4 years ago my valve began leaking moderately, it is now moderate to severe. I have moved from Atlanta and am now in Jacksonville; I saw a cardiologist at Mayo Clinic Jacksonville who did an ECHO, a Nuclear stress test and I will be having a TEE soon. From the ECHO, my anterior leaflet is causing the leaking and I was told valve cannot be repaired; it will have to be mechanical. I would like to think the Dr is wrong and the TEE will show I can wait awhile, but I also want to be healthy enough to have the surgery. I want to be able to understand the monitoring of my INR, etc. However, I will dread the surgery. Last time it was the Davinci Robotic minimally invasive, under my right arm. This time either under arm or through chest. Ugh!! Please let me know what to expect and types of valves to research, if I even have a choice. A friend told me with medicare, one must go with the options. Thank you and it's nice to be back on this forum again learning and sharing.
