I was born with a bicuspid aortic valve and had a commisurotomy in 1967 and had the valve replaced in 1975, when I was 12. Last year (age 54), I found I had an ascending aortic aneurysm and had to have the aorta and the valve replaced (again). Yes...it's scary but you need to make sure you find a surgeon you are comfortable with and can trust. My wife still can not understand how I could have gone in for the surgery and not be scared. I told her that there was a reason that I found out about the aneurysm (I had no symptoms and actually found out about it on the web) and then found this particular surgeon. I knew that with all of that in my favor, I would be fine. I had the surgery on 9/11 and now we don't have to worry about it. So..what I am saying is go get it fixed and you won't have it hanging over your head. It's worth it!
Thanks for the link. i was just diagnosed with mitral valve stenosis with severe mitral valve regurgitation and was told my only option was to have my valve replaced. Since that time i have been doing as much research on my condition as i could. Since i can no longer work and have all the time in the world to think about this. I was also told that since i am having symptoms it is very important to get the surgery done fairly quickly by a cardiologist which is rather scary.
