I agree about your comments on the Resilia. Right now they are selling hope, but there is no data to support that it will last any longer than other tissue valves and there won't be for another 5-10 years. I was leaning towards the Resilia initially, with the hope that I would get 15-20 years out of it. Ultimately, decided I could not bank on hope and went with the hard data pointing strongly towards mechanical valves for longevity in my age bracket. It will be fantastic if the anti calcification treatment is proven to extend valve life expectancy, but this just can't be said yet.
I agree also on your comments on TAVI/TAVR. They really don't know how long they will last. I think it makes great sense to use them for elderly high risk patients who might not survive open heart, but they are now approved for low risk and starting to do some in my area on younger patients in their 50s and 60s. In my view, this is very hard to justify given the very low risk of OHS for low risk patients and the unknowns regarding longevity of TAVR. BTW, my local cardiologist believed that if I could just hold on for a few more years that I would be a TAVR candidate, as TAVR is moving quickly into the BAV world. Just so that I knew whether TAVR was an option, I was evaluated at Scripps in San Diego for TAVR. I was told that due to the fact that my calcification was unevenly distributed, I was not likely a candidate. Knowing what I know now, even had they said I was a good candidate, I would not have chosen TAVR, given the unknown durability and the certainty of future operations.
