Although rare, embolization or migration of transcatheter aortic valves into the left ventricle has been described. We report a case of very late migration of an Edwards Sapien XT (Edwards Lifescience Corporation, Irvine, California) valve that was placed 4 years prior to the development of recurrent severe aortic stenosis with the transcatheter heart valve situated below the native stenotic aortic valve in the left ventricular outflow tract. The management options in this scenario, and outline how they successfully treated this challenging case with transfemoral TAV-in-TAV have also been discussed.
虽然罕见，但经导管主动脉瓣置入后发生瓣叶栓塞或迁移进入左心室的情况已有报道。我们报告了 1 例非常晚期的 Edwards Sapien XT（爱德华兹生命科学公司，加利福尼亚州欧文）瓣叶迁移病例，该患者在 4 年前因重度主动脉瓣狭窄行经导管主动脉瓣置换术，当时该瓣叶位于左心室流出道内原狭窄主动脉瓣下方。本文还讨论了这种情况下的处理选择，并概述了如何通过经股 TAV-in-TAV 成功治疗这一具有挑战性的病例。
