There has been a worldwide rapid adoption of transcatheter aortic valve replacement (TAVR) as an alternative to surgical aortic valve replacement (SAVR) for patients with severe aortic stenosis. Currently, more TAVR explants with SAVRs are performed than TAVR-in TAV. TAVR explantation is a technically hazardous procedure mainly due to significant aortic neo-endothelialization which incorporates the TAVR valve. Surgical techniques for TAVR explantation are not well established and surgeon experience at present is limited. In this manuscript, we describe our technique for surgical explantation of transcatheter aortic bioprosthesis. Familiarity with the procedure and its clinical implications is essential for all cardiac surgeons.
经导管主动脉瓣置换术（TAVR）已在全球范围内迅速取代主动脉瓣置换术（SAVR），成为严重主动脉瓣狭窄患者的治疗选择。目前，行 TAVR 瓣膜取出术联合 SAVR 的病例多于单纯 TAVR。TAVR 瓣膜取出术是一种技术风险较高的手术，主要是因为严重的主动脉新内膜化，其中包括 TAVR 瓣膜。TAVR 瓣膜取出术的外科技术尚未完全确立，目前外科医生的经验有限。在本文中，我们描述了经导管主动脉生物瓣的外科取出技术。所有心脏外科医生都必须熟悉该手术及其临床意义。
