fwiw, biological heart valves, as opposed to metallic valves, are already quite commonly used today. biological ones are typically made from either cows, or pigs (bovine, porcine respectively). but this is on another level altogether.
I had heart surgery 2 months ago to repair my mitral valve. In the lead-up to that, I had to make a decision what to do if it turned out replacement was needed instead of repair. Choices were metallic valves requiring me to be on warfarin the rest of my life or pig-derived valves. I chose the latter, mostly to avoid warfarin for life, but also because my surgeon was a PhD for work on creating biological-derived valve…
GoreTex being the brand of a material that was put into your heart sure sounds amusing.
