From what I just learned, you don't have surgery for the prolapse, only if it progresses to severe regurgitation or if you progress to other associated problems like atrial fibrillation, enlarged left ventricle, CHF, SOB with minimal exertion, etc. The docs told me I'd never have a heart attack, but if I pushed myself too hard I could have too much backflow of blood in my heart and I could pass out. I never thought I'd go into atrial fib and require the surgery so young though. It was a big monkey on my back that always loomed in the front of my mind and is now over and done with, and for that I'm glad. The surgery was tough to go through, physically painful and very emotional.
I had chest pains pre surgery for a few years. Docs told me it wasn't angina, as my coronaries were clear. They said it could be the chords that open and close the valve being stretched, it could be psychological because now I know I have a heart condition, and I am a neurotic/worrier type guy, and I have a stressful job (police officer), or my chest pains could be a combination of both. I was never given a definitive answer for my chest pains.
