I'll try to keep this brief. I was diagnosed with BAV & ascending aorta aneurism at age 50. Monitored the aorta for 2 years and had replaced by dacron graft at 52 at the Cleveland Clinic. Surgeon inspected the aortic valve and confirmed it to be a unicuspid that was healthy and functioning so he left it alone. Here I am 7.5 years later with severe stenosis and need replacement soon. I'm very healthy, active and asymptomatic. Heck, I walked over 12.5k steps at the Cleveland Clinic the other day walking between the many testing area's. I've pretty much decided that I only want to do this one more time. This second time is difficult enough. I can't see installing a tissue valve with an expiration date of anywhere between 1 and 20 years. Yes, the thought of Coumadin sucks, but I feel it safer than more invasive surgeries down the road. Yes, there is TAVR but that has many potential risks as well.
So, for me it appears to boil down to either the St. Jude Regent or On-X valves. Has anyone directly compared these two valves? They are both made from the same pyrolitic carbon and are very similar in design. But, my surgeon appeared to favor the SJ as it appears a larger SJ can be installed in the same area as a On-X, and he mentioned the On-X is "Bulky" and I guess requires a larger annulus for proper installation. Which valve has better hemodynamics? They both appear to be robust enough and tested to last a "lifetime". Any thoughts/comments/experiences appreciated. I apologize if I am re-visiting an old topic. Thanks everyone! By the way, this is a great site.
