You use bovine or porcine generally. They last about 10 years. Metal valves last 30 years but require anti coagulation. Since porcine and bovine valves are zero from à immunogenicity standpoint, they’re ideal unless we could get human ones that are plugged into the circulatory system.
Although with a pump heart you’re going to be on blood thinners anyway. And probably a few other things.
The dream of where the heart is headed is to growing new ones. The best heart is a human heart suited to you
- sizzle 5y agoIf they only last 10 years.. they have to cut you open to replace them assuming you live a few decades??
- robbiep 5y agoThey last 10 years ‘or so…’ some up to 17-20, so there’s a variability there, but they fail gracefully so you can monitor which is nice (as another commenter pointed out). Tou can replace with transcutaneous valve replacement (like a stent, through a blood vessel) or open operation
