对于手术修复失败的高风险患者,环内瓣膜手术是一种可行的解决方案。左心室流出道阻塞的风险增加了挑战,和经导管的方法来防止它是技术上的要求,往往不能解决它。我们证明了经中隔球囊辅助二尖瓣前叶转位用于环瓣植入的可行性和安全性。
Valve-in-ring procedures represent a feasible solution for high-risk patients with surgical repair failure. The risk of left ventricular outflow tract obstruction increases the challenge, and transcatheter approaches to prevent it are technically demanding and often do not resolve it. We demonstrate the feasibility and safety of a transseptal balloon-assisted translocation of the anterior mitral leaflet for valve-in-ring implantation.
