As a tissue advocate, I have to say that there have been significant advances:
1) The Bovine pericardial valve is now stretching towards 20 years of use, with excellent results in adults. Common stats are 80% chance of seeing 20 years (bear in mind, that is all the data available)
2) The Homograft is also approaching 20 years with similar results. The preservation techniques have advanced dramatically. Again, that is all the data available, but it could last forever.
I do not take coumadin, and at 10 weeks post I am beginning to believe this event is getting behind me. I do not think it takes a year to recover - maybe a year to forget. None of us will ever fully get past the assault on our chest! My biggest lingering effect is an accelerated heart rate and higher BP, but there are no other abnormalities in the EKG and it is expected to return to normal (compare pre-op: resting pulse 75, BP 115/75 - post-op: resting 96-120, BP 140/100). We are trying Cardizem again to slow it down.
Perhaps I am fortunate in my recovery, but I also believe that you should have surgery BEFORE you are sick! I was in pretty good health to start with, altho no athlete, and had no other risk factors. I was also highly motivated to make this work - it was not an option to have valve replacement, so I committed myself to the course with a positive mind set and a plan to recover.
I am working full time, in every sense of the word. Real estate is a full-on proposition if you are making a living at it. I have 3 teenagers, we have a full schedule, I go to rehab 3x a week... in short, life is not just getting back to normal, it is better than normal. I gladly accept the soreness in the chest for the increased blood flow and energy.
I don't think one should be so quick to dismiss the tissue option. And Exanta may not be the magic bullet everyone thinks it is. And Coumadin, while certainly a manageable drug, is still a significant lifestyle-altering regime.
Anyway, that is my thinking on the subject - of course, I HAVE a Homograft, so I will certainly defend it
