I’m wondering why your doctor preferred a pig valve ( that’s what it was called in 2015) when I had my open heart surgery to remove my leaking valve and the surgeon recommended the mechanical valve.

He said that a tissue valve has around a 10 year lifespan and a mechanical aortic valve has a 40 year lifespan so I opted for a mechanical valve and have had nothing but a good ticker at every exam. That’s 8 years so far.
