Hey Sue
Sorry (well I'm sorta not) that I can't offer direct experience on TAVR, however what I can say is this: I worked for some years in a support role for equipment for the elderly. What that made clear to me is that after a certain age you really don't want
invasive surgeries because its (
speaking statistically) very risky that your body won't recover.
So I would give a hard look at the TAVR options at 80 years of age.
Of course I don't know anything about your health and you could be one of those people out on the XC Ski track who out do me on the up-hills and have greater fitness than the average 40yo, however I've still seen "tough old sticks" go backwards and into the grave from such trauma as hip surgery.
There is nothing with no risk, but from what I see the risks of TAVR are being better managed (
you know, like things floating off down the blood stream having been dislodged by the catheter and causing strokes) than they were.
I'm seeing in the literature greater durations of TAVR (meaning they'll last you longer without re-intervention) and so from what I read something over 5 years (and probably 10) is expectable for someone like you (again making assumptions).
Basically the valve is literally a plumbing issue, so don't avoid getting it fixed because it can ruin your entire house if you do ignore it.
Get some opinions and see how you go and come back here with any points that arise from that and see what all of us have to say. There are a few smart-arses here who seem to say "don't ask some random person on the internet" *(
but as posters here themselves seem to DunningKrugerly omit themselves from that assessment), however I'd say that by asking the crowd you can find wisdom in the overall assessment of answers. The
Wisdom of the Crowd is a well known phenomenon.
Its not that we're cardiologists, but as patients ourselves (and having been around the streets a while) can offer viewpoints and further questions to ask.
Best wishes
