Where I am at today - long hemming and hawing post
Dr. Miller is out of town until the night before my surgery, so I talked with a surgical colleague today. He was quite open. My reading of our discussion is that he agreed that despite the strong preference Dr. Miller expressed for a mechanical valve based on the likelihood of reoperation with bio at my "young" age, it is a close call when you consider all other variables. Anticoagulation is not inoccuous or completely effective. He expressed hope for better alternatives to Coumadin, but noted he was saying that 10 years ago. Reoperation could be handled, perhaps with newer approaches that wouldn't require OHS, and he didn't paint reoperation as a big problem for them, at least. We talked about the valves they use routinely. They are happy to put in whatever I want, but they have most experience with and routinely stock the SJM Regent mechanical and the Edward's Piermount Magna bio valve. If I wanted the SJM Biocor, for example, they would have to order it (no problem with a few day's notice) but he was very upfront that they have little experience with it and his view is that the Edwards valve has some features that are better, but it's not worth going into, as I see this all as largely an issue of personal preference.
I've been going over and over this in my head. My conlussion is the data needed to make these choices unequivocally are simply not there. For example, the SJM Biocor valve seems to have the most published data on durability, but after looking it over I think it is rather disappointingly meager and fraught with patient population issues such that it really does not apply well to me. There is no magic about that valve that should make it any more durable than the alternative newish biologics. I read a discussion by the author of one of the SJM studies in which he basically says all the different new generation valves are just variations on the same theme and probably not significantly different in terms of durability, whether there is published data or not (my interpretation).

Conversely, although the On-X valve appears based on company claims to have superior features that should lead to superior results compared to the older SJM valve dsigns, there is no substantial data. It may be great, but it's all supposition at this pont.
So, the underlying problem with making a sound decision is that not only is this a complicated subject, but the information you would need to make a concretely rational call is just not there. The bio valves appeal to me based on "lifestyle" and to some extent, safety issues around anticoagulation (granted this does not appear to be a problem for most patients). Yes, there is the known issue of reoperation, be it 5-10 or 15-20 years. Should I live as long as I expect to, I will certainly require reoperation. So, in a general way, it boils down to which do you WANT.
So, my leaning at this point is to not quivel much over getting a particular mechancial valve or particular bio valve but to use what they favor, as I don't see good reasons to overule that. Granted, at the Cleveland Clinic, that would mean I would get a different valve. So, be it. That doesn't concern me. One is not right and the other wrong. These are preferences, and maybe biases. Maybe if I took 15 years to become an accomplished thoracic surgeon I would have different ones.
If I were 70+, the choice should be clearer. At my age, I'm now seeing it as a toss-up in terms of risks. It's not even worth it to make up a pro and con table, although I probably will as a large part of me still wants to believe there is a right and wrong answer and I just need to find it. Yes, perhaps we will see 15 years from now that there was a right answer. I don't think that can be sorted through right now.
To be continued...
