Here’s the research paper. Notable from the abstract that this is an acquired condition that tends to be diagnosed in later middle age.
Its a statistical extrapolation/model. More than that I can’t say, will happily defer to one of the Fivers who likes it deep in the weeds

I would say that the vaccines are far more likely to trigger severe incidents of Aortic Stenosis, it’s sinister that such research should appear now eg; “oh we have found that certain invasive treatments (such as vaccination), can trigger incidents of severe Aortic Stenosis etc.” to my mind this under-reported condition has a history of being linked to (and esp. aggravated by), such treatments, this is why it has been left-on-the-back-burner until now! You see…?
Nb. I suffered from severe blood loss as a teenager, this left me with a legacy of “valve issues” which have never been addressed (at least not “conventionally”).

The research, to use the term loosely, also seemed to be paving the way for an expansion in corrective surgery (again I use the term loosely). If there’s a way to manufacture a new niche for the health vultures to flock they will have this figured out.
Who needs a marketing budget when you’ve got university press officers and captured governments…?
Hi folks, the biggest source of “corrective” medicine apart from the jab seems to have been midazolam over the last couple of years!
