Hey all - I too am struggling with the decision of whether to get a mechanical or tissue valve. Just found out I have a ascending aortic aneurysm and a leaking BAV approximately one month ago after a visit to ER thinking I was having a heart attack. Never knew I had any heart issues or BAV and am now scheduled for surgery July 28, 2010 - which also happens to be my birthday! I am not going to lie - the whole thing is a bit overwhelming. I am 45, female, healthy, non-smoker, not overweight, etc. so I am in shock a bit. I have been reading all your posts and am so confused. First I was thinking mechanical, but I am scared of being on Coumadin for the rest of my life which could easily be 45+ years (my grandmother is 98!) and has anyone had a mechanical valve for that long without reoperation? Heck half the time I cant even remember to take my thyroid medicine! Now I am thinking maybe a tissue valve which may get me to 55-60 yrs old and then do mechanical. But the thought of another surgery scares me. I hear of people talking of hearing the ticking of their valves and irregular heart beats and that is freaking me out!! The only symptoms I have now are some shortness of breath and some chest pains. Maybe I should try to push off surgery a year or two to buy me time - I AM TERRIFIED and CONFUSED!!!
