Valve-in-valve transcatheter aortic valve replacement (ViV TAVR) is an appealing alternative to surgical intervention on failed aortic prosthesis with comparable safety and efficacy. ViV TAVR has proven to be a technical challenge in stentless bioprosthetic aortic valves like free style aortic valve prosthesis. In this case series of two patients we report the utility of transesophageal echocardiogram guidance to help visualize surgical annulus and TAVR deployment.
瓣中瓣经导管主动脉瓣置换术（ViV TAVR）是对失败的主动脉人工瓣膜进行手术干预的一种有吸引力的替代方法，其安全性和有效性相当。对于无支架生物人工主动脉瓣膜，如自由式主动脉瓣膜假体，ViV TAVR已被证明是一项技术挑战。在这个包含两名患者的病例系列中，我们报告了经食管超声心动图引导有助于可视化手术瓣环和TAVR植入的作用。
