[Early Structural Valve Deterioration of Trifecta Biological Prosthesis;Report of a Case].
Trifecta valve is a 3rd-generation, stented bioprosthesis which is made from one bovine pericardial sheet. A 77-years-old male patient had undergone combine aortic valve replacement (AVR) using a 23-mm Trifecta valve and ascending aorta replacement for severe aortic valve regurgitation and ascending aorta aneurysm. The postoperative period was uneventful. However, he presented with dyspnea on effort and severe aortic valve regurgitation 31 months after operation. Re-do AVR with a new bioprosthetic valve was performed via 2nd sternotomy. Surgical inspection revealed that the Trifecta valve had a parastent tear in the left-coronary cusp without any calcification or vegetation. We report our experience with a case of early structural valve deterioration of Trifecta biological prosthesis and review relevant literatures.
