A 79-year-old man underwent tricuspid valve replacement (TVR) with a bovine pericardial bioprosthesis, Carpentier-Edwards Perimount (CEP), for tricuspid regurgitation 27 years earlier. Twenty-one years after the first operation, he underwent re-TVR with a bovine pericardial bioprosthesis, Magna Mitral Ease, due to prosthetic valve dysfunction. Since the prosthetic valve dysfunction progressed again, the third TVR was performed six years after the second operation. The findings of the resected bioprosthesis showed sclerosis of the septal cusp, and pannus formation between the septal and posterior cusps. For the third TVR, the porcine bioprosthesis Epic was used. Neither transvalvular nor perivalvular leakage was observed postoperatively, and the patient was discharged without any complications.
27年前，一名79岁男性因三尖瓣反流接受了三尖瓣置换术（TVR），使用的是牛心包生物瓣，即Carpentier-Edwards Perimount（CEP）。首次手术后21年，由于人工瓣膜功能障碍，他接受了再次TVR，使用的是牛心包生物瓣Magna Mitral Ease。由于人工瓣膜功能障碍再次进展，在第二次手术后6年进行了第三次TVR。切除的生物瓣检查结果显示，隔叶瓣叶硬化，隔叶与后叶之间有血管翳形成。第三次TVR使用的是猪生物瓣Epic。术后未观察到瓣周漏或瓣内漏，患者无任何并发症出院。
