There can also be a point at which what could have been a repair becomes a replacement. I also remember my surgeon telling me that if a repair was done prior to the onset of significant symptoms (e.g. Afib), then I would be essentially cured and my life expectancy would be the same as if I had never had my mitral valve problem, whereas, if I waited until after my heart started to fail, it still may be able to be repaired (or replaced), but my life expectancy would have already been adversely impacted. He illustrated his point by bouncing a pen toward the edge of the desk and showing that I was hovering near the edge. As he dropped the pen over the edge, he said, "should we wait until you go over the edge?". He also emphasized his point by asking, "when is your valve/heart going to fail?" or "when are you going to go into Afib?". To which I obviously said,"I don't know.". He said, "oh yeah...[smacking his forehead]...neither do I.". I was not happy about having surgery...especially because I have a 3 year old daughter with a stay-at-home dad...I provide all of the financial support for our family. Now that I'm on the other side, I am soon happy to have this ordeal over with. I was healthy going in, so I've gotten back to "normal" fairly quickly (almost 6 weeks, post MV repair). That being said, my cardio did "protect me" from the big bad surgeons for the five years leading up to my surgery by monitoring me very closely for any changes. That's my experience...for what it's worth...
