Hi Ward
Welcome to the site. Making the decision between tissue valve or mechanical valve is possibly the biggest decision you will have to make in your life. Unfortunately, there is no perfect solution or choice.
It really boils down to a mechanical valve + coumadin for the rest of your life or a tissue valve (including an allograft) with no lifestyle restrictions or drugs but a reasonable possibility of a re-op down the track.
All the coumadin people on this site will tell you that if they had their time over again, they would still make the same choice. I think the tissue people would say the same. That's because we have all learnt to live with our respective fates and so few of us have done both, so we can't compare.
Anyway, a few thoughts to consider :- We humans are very resilient and we get used to almost anything, no matter how daunting it might seem beforehand. (If you have never brushed your teeth before and were told you had to start this twice daily routine, you'd think what an imposition).
Modern cardiac surgery is pretty straightforward and routine. In my case, I was in hospital 1 week then 1 week feeling a bit sorry for myself and then I started getting back to normal. I was back at work 6 weeks after surgery. I have friends who have been inconvenience or "suffered" more due to broken limbs or torn muscles. So for me, the prospect of another surgery doesn't hold the fear that it does with some others.
Bottom line :- draw up a list of pros and cons for each option and decide which of those factors has the greatest impact (positive & negative) on YOU personally. Ask questions, read articles and you will know when you are ready to make a choice which you feel is RIGHT FOR YOU. It's a personal decision for every one of us and what was right for me may not be right for you.
Hope this helps
Regards
