Gina had the words of wisdom, as she often does. "If it ain't broke, why fix it?" It would be silly for someone with a mechanical valve that gives every indication of working forever to opt for an "advance" that might or might not work as well as advertised.
As for someone who has a tissue who hopes it'll last him 15-20 years and take him into his 80s (if he makes it that long) -- in other words, me -- sure, that guy would be a willing candidate for some marvelous advance.
Personally, I'm hoping this can be performed in the year 2025 by a medical technican resembling Christie Brinkley (who no doubt will be just as well preserved then as she is now),who can just wave a magic wand over my chest and bestow on me a nice new valve whenever it's needed.
