Thank you for posting the two links regarding mechanical valve v biologic valve. Has your research indicated whether porcine or bovine valve is a better option?

Hi Anna, I did some research and I'll copy the link below for a paper that surveyed almost 10,000 patients and gave a slight advantage to bovine. I'm not sure why a surgeon would recommend porcine, but they still do - maybe it is a size thing. My understanding is... Read more.
