Leaflet tear in a Trifecta aortic bioprosthesis 34 months after implantation

Abstract

Bioprosthetic valves are used in aortic valve replacement to avoid lifelong anticoagulation. Bovine pericardial valves have excellent haemodynamics and equivalent freedom from reoperation compared with a porcine bioprosthesis [ 1]. However, early failure (parastent post-cusp tear) can take place due to mechanical stress. We report an acute structural failure on a Trifecta pericardial valve (St Jude Medical, Inc.) explanted after 34 months from a 71-year old woman.
