... and I still haven't decided.
I think I know what many will say when done reading this, as most of you out there are on the other side of this decision and have a vested interest in maintaining a positive outlook on what is and will be the AVR reality for the rest of your lives. But I hope you can bear with me, read this all the way through and please try to respond objectively. I'm not asking you for my answer -- that's for me to work out, I know. What I'd like is for you to critique my thought process.
All things being equal with regard to morbidity and life expectancy, and that is truly the case between the mechanical and xeno valve type groups, I am very close to sealing the deal on a mechanical valve. What really got me there were the latest studies and trends for the lower INR recommendations for the On-X valves, which my surgeon prefers for MHV (and so do I). Same stroke risk with even lower bleeding risk? Sounds like the MHV side is tipping the scales faster than bioprosthetics. And there seems to be no slow down in the race to replace warafin. Eventually it'll happen and its far easier and cheaper to do trials with new anticoagulants than it is to do trials with new valves.
As has been mentioned in many prior threads on this Valve Selection forum, choosing while younger than 50 is raw deal. And yes, betting on the future, I agree with what I've read before here, is not the smartest bet. I've read up and down about TAVR. I've read about other possibilities that touch on if not just plain vapor within the realm of fantasy. I've read the unhappy testimonial of a fellow on this forum who was made promises by his surgeon about TAVR some years ago and now he's on his second replacement. He's not a happy camper as I understand. TAVR is not ready, even with filtering, and baring some ingenious advancement, stroke risk will always be far worse and is still only a risk that should be taken by those who would fair worse with a sternotomy.
But then, I had another conversation with my father, who ironically got a DVT the same time I learned about my aortic aneurysm. He thinks I should avoid warafin as long as I can and that got me to think more about the future of the above technologies. No I haven't turned to banking on TAVR. I'm not banking on anything specific. But, what we do know is pretty consistent is that all heart valve technologies have a track record of improving over time. So what if having this choice in your 40s is not a burden but a gift? The gift is that you can get a tissue valve and get a re-operation in your 50s with a decade more research under valve replacement technologies. I realize its not a guarantee, but, is it worth the risks? Well, consider the following...
Someone might instantly reply that re-operation is a huge risk. But everything I've read here and in NIH, AHAJ, ACC, etc, studies or reports show that mechanical and tissue choice is a wash even say so when including re-opreation in risk calculations. If re-operation is such a huge-er risk, then how can this "wash" be true? The recovery is no walk in the park. But what if means the possibility of a mechanical valve that needs nothing like warafin or any coagulation at all? Or what if it means a life-long-lasting bioprosthetic? I'm not putting my eggs in one basket of one type of valve, I'm thinking my youth lets me put my eggs in every basket, or if you will, the "time basket". I'm "only" 44. I'd only take this gamble once.
Is it worth it? Thoughts?
