mate, I think you need a bucket to catch the dribble. that link, you either didn't read it in it's entirety or you genuinely do not understand it.
your "peer reviewed paper" was published FOUR YEARS AGO, submitted January 2018 and based on valve research from one brand!
So, no, it does not support any of your comments minus one question you asked about the use of pace makers in the future. you also misinterpreted or misrepresented that information as well.
I do not believe for one second your daughter, "the GP" gave you that link as current information.
Indirectly, that article actually helps AVR's case by pointing out all the things Anteris have done and designed to overcome the challenges of SAVR & TAVR.
I'm starting to wonder if you are reading "AVR" the abbreviation for "Aortic Valve Replacement" in these research papers and interpreting it as "AVR" the Anteris ASX ticker! Either that or you're just gas lighting now.
