I believe now (more so than I did 10 years back) that having a bio as your first intervention can be a good thing. Its good because it transitions you from being able to recite data to actually possessing experiential learned knowledge. You
grok it if I may use that word.
During recovery you become aware of what all those words people said mean when over (say) 10 to 15 years you go through recovery, to yearly examinations, to eventually turning the corner when Structural Valve Degradation (SVD) becomes an actual in your personal face reality. I recommend you read this about SVD.

You'll experience it and I believe that if you don't experience it you may well always wonder if that was what really happened. When people close to me have died suddenly and unexpectedly there was always some nagging part of my personal unconscious half expecting to see them ... this went on for years. This never happened to me with those who I saw getting sick, went to sit beside them during Chemo, went through remissions with them and then eventually there was no remission and I went to see them in their last days at the hospital and finally went to their funerals.
So based on what you've said, unless you decided otherwise I would suggest that you get a bioprosthesis and consider it not just "kicking the can down the road" but part of your personal life journey.
Remember, my journey started when I was about 6, with all the hospital visits (which increased in frequency) and then an OHS at 10, a (then called) catheter examination (as the technology was introduced) of how the repair was going, then at 28 got somebody elses valve, then at 48 (with the development of an Aortic Aneurysm) chose a mechanical valve with my bental.
I've since learned a lot about all of that and what it entailed and what I was lucky to avoid. I did however have a bit of a bumpy first year after an infection from the OHS #3 emerged.
