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?

John Dodson

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.

The pericardial heart valve was invented by Marian Ionescu, a British surgeon working at the General Infirmary in Leeds, England.[1] He created this artificial bioprosthetic heart valve as a three-cusp structure made of chemically treated bovine pericardium attached to a Dacron cloth-covered titanium frame.[2]

Gerald Poulton

Some of it does depend on the position of the valve, for aortic valve replacement, bovine seems to be the present choice. When I found out I needed a valve replacement my cardiologist and surgeon basically told me at 65 years young that I needed a mechanical valve, my research... Read more.
