  • Title: Leaflet tear in a Trifecta aortic bioprosthesis 34 months after implantation.
    Author: Piñón M, Durán D, Pazos P, Pradas G.
    Journal: Interact Cardiovasc Thorac Surg; 2015 Feb; 20(2):281-2. PubMed ID: 25404230.
    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.
