The Trifecta tissue valve (Abbott, Illinois, USA) is an externally mounted bovine pericardial aortic valve (AV) prosthesis with adequate haemodynamic performance and better early results than another option. However, concerns have been raised about its durability. Recently, reports have emerged about an increased incidence of early structural valve failure after Trifecta implantation, where leaflet tear(s) with dehiscence along the stent post was the primary mode of early failure. In this article, we present the case of a patient in her 70s, 7 years after AV replacement with a Trifecta valve, who developed progressive dyspnoea. Physical examination revealed signs of chronic severe aortic regurgitation (AR). The initial transthoracic echocardiogram showed severe transvalvular AR, but the aetiology could not be determined. Cardiac computed tomography (CT) revealed a flail non-coronary cusp of the Trifecta bioprosthetic valve without vegetation. After discussion, we concluded that our patient was suitable for valve-in-valve transcatheter aortic valve replacement (ViV TAVR).
三尖瓣组织瓣(美国伊利诺伊州雅培)是一种外部安装的牛心包主动脉瓣(AV)假体,具有足够的血液动力学性能,早期结果优于另一种选择。然而,人们对其耐久性表示担忧。最近,有报道称在植入三尖瓣后早期结构性瓣膜失效的发生率增加,其中瓣叶撕裂伴有支架后裂开是早期失效的主要模式。在本文中,我们介绍了一位 70 多岁的患者的病例,她在 7 年前接受了三尖瓣置换术,出现了进行性呼吸困难。体格检查显示出慢性严重主动脉瓣反流(AR)的迹象。初始经胸超声心动图显示严重的跨瓣 AR,但病因无法确定。心脏计算机断层扫描(CT)显示三尖瓣生物瓣的非冠状动脉瓣叶游离。经过讨论,我们得出结论,我们的患者适合进行经导管主动脉瓣置换术(ViV TAVR)。
