this is not really anything I've spent much time thinking about (that is not to say none, but relatively not much). I have my own opinions which are perhaps not worth sharing here. However I'd point you at the following readings
Calcium transport and calcium signaling are of basic importance in bone cells. Bone is the major store of calcium and a key regulatory organ for calcium homeostasis. Bone, in major part, responds to calcium-dependent signals from the parathyroids and ...
Advancing age and loss of bone mass and strength are closely linked. Elevated osteoblast and osteocyte apoptosis and decreased osteoblast number characterize the age-related skeletal changes in humans and rodents. Similar to other tissues, oxidative stress ...
I think this is largely a different question because your bones are in themselves an organ (just as your skin is) and what we are seeing in the valves is more akin to what we see in plaque in arteries than bone. For that subject I'd point you in the direction of glycocalyx
(I'd start on that paragraph but move to the start of the article before progressing far if you want to grasp the subject). The subject is complex and tightly interwoven with understanding endothelia and the valves are indeed related tissue (AFAIK).
Heart valves are sophisticated cellularised structures that perform a complex series of dynamic functions during each cardiac cycle. The endothelial cells (ECs) that cover both surfaces of the valve, play an important role in ensuring that the valve functions are in an optimal manner. They are...
Its important to recall that the so-called "bio-prostheses" are about as bio as your leather shoes, and have been treated with a chemical process which is different to but not unlike the process we call tanning. I would strongly recommend you read the following
and in particular look at SVD in the section here
If all that sounds complex I'm sure it is. I'm fortunate to have had both a long time to study this and a leg up based on my studies.
Ultimately much of the choice and the imperatives which drive it are pretty simple because we have "observation" from which we can determine statistical likelihoods. These are things like your age at time of surgery. I don't recall your age (and its not in your about section for me to look it up, but as I see it:
- you have had one OHS already (the 'valve sparing' operation)
- I suspect you're over 50 (but I don't know the ceiling of that)
So I'm going to go with the following advice:
- the further over 65 you are the more a Reslilia makes sense
- the closer you are to 50 the more a mechanical valve makes sense
those two advices are more common outside the land of th free (or "free maket direct to patient advertising land
I'm going to say that no bio-valve maker is presenting data for trials that go past 15 years (and indeed the trend is moving down). This means that "marketing data" can be more of this:

Warfarin is painted as a bogy man by various medical practitioners because they don't have a fhukken clue how to manage it (despite papers as far back as the early 80's) and people come to harm because they simply don't comply with their directions to take their dose.
If you don't actually take a hand in managing your own health (which takes about 5 min a week and as many dollars) then you'll be a statistic.
Lastly (before you do any deep dive into my above articles (from my reference list) I recommend you grab a warm beverage, a pencil and paper and make notes in this presentation.
While a bit dated is well researched and the Dr well experienced and well intentioned.
Lastly a perspective. You don't get better from surgery, you just stop a process which was killing you. You'll swap this out for an injury which requires treatment. One type of "surgical wound" requires further surgical interventions (or cardiology interventional in the case of TAVI) and the other requires you to learn how to manage a drug. This is actually what all diabetics do, but their process is more onerous.
