Procine vs. Bovine
Procine vs. Bovine
Hi Joan --
Happy to share the little I know. They say a little knowledge is a dangerous thing, but that never deterred us, right? ... nor should it, with a few precautions.
There are different varieties of porcine valves, I believe, stented and unstented. I am not very familiar with the "fit" issues. The two particular options I ended up choosing between were, on the porcine side, the new Hancock Medtronics Mosaic, a stented version, I believe, which has been treated to retard calcification; and the Carpentier-Edwards Pericardium bovine valve. As far as I could tell, they both had similar virtues and a track record of lasting up to (or slightly beyond) 15 years, which fit my bill. I gave the Hancock the edge on the advice of my surgeon, because of it experimental anti-calcification properties and because it seemed to have slightly better results in empirical tests, by the articles I read. But both are good options, for sure.
Hope this helps.
Peter
