Long-Term Survival After Bovine Pericardial Versus Porcine Stented Bioprosthetic Aortic Valve Replacement: Does Valve Choice Matter?

For patients undergoing AVR with a stented bioprosthetic valve, with or without coronary artery bypass grafting, the choice of a porcine vs bovine pericardial bioprosthesis does not appear to affect long-term survival or need for reoperation, regardless of valve size or patient age. As such, stented bioprosthetic valves would appear to be fungible, and therefore, valve choice should be driven by local market factors similar to other commodities.
