  • Title: Pure Cusp Tear of Trifecta Bioprosthesis 2 Years after Aortic Valve Replacement.
    Author: Hamamoto M, Kobayashi T, Ozawa M, Yoshimura K.
    Journal: Ann Thorac Cardiovasc Surg; 2017 Jun 20; 23(3):157-160. PubMed ID: 27980283.
    Abstract:
    Trifecta is a stented bioprosthetic heart valve with a bovine pericardial sheet externally mounted on a titanium stent. This valve is applied only for aortic valve replacement (AVR), providing excellent hemodynamics and extremely low incidence of structural valve deterioration (SVD). A 76-year-old woman presented with dyspnea on effort 24 months after AVR with a 21-mm Trifecta valve. Echocardiography revealed severe aortic regurgitation with prolapse of a cusp of Trifecta valve, which suggested that she developed acute heart failure due to early SVD. In the operation, Trifecta valve had a cusp tear near the commissure with circumferential fibrous pannus ingrowth only at the inflow side. There was neither calcification nor infection. The Trifecta valve was successfully replaced with a new porcine bioprosthesis.
