Explore less invasive surgery. Theydon't always have to open you up to do a valve. But not all the docs know how or are qualified. Opening the chest takes a long time to heal and never really heals completely.
That said, I think the valve is more important than the bow, even though I hate to say that. Last year I had endocarditis from an infection and a murmur. I have a borderline Mitral valve I was born with and it's the place everything goes. I don't need it replaced yet, but someday........Hoping by that time, they will have perfected the less invasive surgery and everyone will do that. Anyway, I had no strenth at all and could hardly walk once I got done. So I started back last Nov with a 20# bow, then a 25# Wing, (nice thing is that you get to shoot a lot of neat old bows and work on form -- my little guy still shoots the Wing) and each time I went up 3-5 lbs depending on the bow I could find. As I progressed, each step up went faster. 4 weeks to 3 weeks, to 2 weekts etc. So now I'm at 55# and shooting 50 -100 arrows a day like nothing. Patience. And good luck
