I don't know -- I never really liked peaches and cream. . . but I DO love life post-valve replacement. I had a tissue valve implanted just over 6 years ago, at age 63. I'm not yet worrying about how long it will last, as there is nothing to be gained by doing so. Like Vincent, I believe that I would be dead by now had I not had the surgery. I take some meds, but not due to the valve. I take meds for blood pressure control and lipid control - just as I did before the valve surgery, and I take some other meds for other unrelated conditions. My valve really doesn't impact my daily life. I do have a pacemaker, which brings its own cautions and complications, but that is not related to your question. My valve is pretty much invisible to my daily life. So much so that my surgical scar is almost impossible to see, especially when I've been out in the sun a bit.
Once I got past the initial healing, I did cardio rehab and then went back to my regular 5 days a week gym schedule. The only thing I've had to do is to ensure that my pacemaker is adjusted properly to allow aerobic exercise (it is set to automatically raise my heart rate when my body needs it). I'm getting close to 70 now and still working 50+ hours a week, travelling, working around the house, polishing cars by hand, going to the gym. . . just living the heck out of my life.
The biggest reminders to me of all this are the two appointments I have with my cardio each year. One time we do an echo and consultation, the other is just an office consultation.
the first couple of months of my recovery were a train wreck due to the impact the surgery and meds had on my digestive system (about brought it to a full stop), but once we got that back under control, life has quickly returned to a new normal that is better than it was before surgery.
