The Trifecta valve has been reported to have valve dysfunction months to years after operation. However there were no reports of intraoperative valve dysfunction. A 73-year-old man with aortic stenosis underwent aortic valve replacement using a 21-mm Trifecta valve with Glide Technology (Trifecta GT; Abbot). Hemodynamics were collapsed after aortic declamp because of severe regurgitation, and we replaced it with another biologic valve. We noticed that the removed valve's mount post was open outwardly more than usual. Despite the progress of the biologic valve, dysfunction like this case can occur during operation, and it is important to reoperate immediately even if there is no obvious tear or deformity.
报道称，在手术后数月至数年，三尖瓣会出现功能障碍。但术中并无三尖瓣功能障碍的报告。一名 73 岁男性因主动脉瓣狭窄，接受了 21 毫米三尖瓣带 Glide 技术（三尖瓣 GT）的瓣膜置换术（雅培）。由于严重反流，主动脉钳夹松开后血液动力学崩溃，我们更换了另一个生物瓣。我们注意到，取出的瓣膜的安装柱向外张开的幅度比正常情况下大。尽管生物瓣功能正常，但在手术过程中仍可能发生这种功能障碍，如果没有明显的撕裂或变形，即使在这种情况下也应立即再次手术。
