Early Degeneration Caused by Cusp Tear of First-Generation Trifecta Bioprosthesis.

The Trifecta aortic valve has excellent hemodynamic performance as result of an expansive valve design with a bovine pericardial sheet externally mounted on a titanium stent. We report 2 cases of early Trifecta valve degeneration, both caused by partial rupture of one of the leaflet cusps 3 and 4 years post-implant. Post discharge, both patients had routinely performed echocardiography check-ups, without signs of valve failure. Transesophageal echocardiography performed during emergency hospital readmission due to severe dyspnea revealed transvalvular aortic regurgitation without signs of endocarditis. Urgent redo-surgery was successful in both cases, replacing the Trifecta prosthesis with a different bovine bioprosthesis.
