I'm sure you've got more to read than time to do it Michele so I'll limit this post to second the recommendation to have a Second Valve Choice in mind before going in for surgery.
After considerable discussion with respected physicians and reading the pro's and con's of Tissue vs. Mechanical, I decided I would like to have a Bovine Pericardial Tissue Valve from Carpentier-Edwards. My surgeon agreed to this wish and all was set, or so I thought.
When I came to, the first thing my surgeon said to me was that he implanted a St. Jude Mechanical Valve (which of course meant Coumadin for Life). My family was in tears.
Then he said, "and I don't think you would survive a third surgery". You can imagine how I feel about facing a third surgery now that my Mitral Valve is barely functioning! (The concensus is that surgeon #2 meant that he didn't think I would survive having my Aortic Valve replaced and that is why he implanted a mechanical valve with excellent durability).
Severe scaring from Radiation Threatments decades ago fried my heart and is responsible for most of my heart issues. The point of my story is that the surgeon can't really know for sure what he will find until he gets in there, hence the value of expressing your second choice in advance.
FWIW, day to day living on Coumadin has not been much of a problem (except when my 50 lb. puppy pulled me into a tree, or the BP Cuff Maxed out during my last hospital stay).
I was VERY concerned about having other invasive procedures due to the necessity of going off Coumadin briefly for the procedure (a.k.a. Bridging Therapy) which has proven to be much less of an issue than I feared. I've had a colonoscopy, upper endoscopy, and yep, a heart cath since being on Coumadin, with NO problems from any of the procedures. (I actually fell asleep for 15 minutes during the Cath!
That said, I'm VERY impressed with the third generation On-X pryolitic carbon mechanical valve and have informed the surgeon I selected for my MVR that is my first choice, followed by another St. Jude Mechanical Valve if the On-X is not viable.
