20 years ago I had a St. Jude Aortic valve put in. I am doing very well. I also have A-Fib which I have livedcwith for at least 10 years. I was on a medication for the A-Fib which worked for a while, then had 2oblations to try and get it back in rythym that did not work. So, I have lived with it for 10 years. Everything (all my medications and exercise and watchful eating) seems to be working well. I just wonder what is the life expectancy of my valve.
