Redo transcatheter aortic valve replacement (TAVR) may pose the risk of coronary flow obstruction. We report 2 cases of severe TAVR regurgitation due to different physiopathological mechanisms in which TAVR-in-TAVR could be at high risk for sinus sequestration. Both cases were successfully treated by in-series implantation of a second transcatheter heart valve, thus avoiding sinus sequestration. ().
再次经导管主动脉瓣置换术（TAVR）可能会带来冠状动脉血流阻塞的风险。我们报告了2例因不同生理病理机制导致严重TAVR反流的病例，其中TAVR-in-TAVR可能存在较高的窦房结隔离风险。这2例均通过串联植入第二个经导管心脏瓣膜成功治疗，从而避免了窦房结隔离。（）
