Tears in bioprosthetic heart valve leaflets without calcific degeneration.
Abstract
BACKGROUND AND AIM OF THE STUDY: The mechanism of structural failure of bioprosthetic valves is still not clearly understood. This study was undertaken to assess pure leaflet tear as a mode of failure in porcine and pericardial bioprostheses.
METHODS: Of 246 bioprosthetic valves (109 porcine, 137 pericardial) implanted between 1975 and 1991, 101 had to be explanted and served as the study population.
