This case report underlines the complexity of the transcatheter aortic valve replacement (TAVR) procedure where rare complications sometimes are inevitable, even in experienced hands. Supra-annular dislocation of the balloon-expandable prosthesis was caused by loss of capture of the temporary transvenous pacemaker lead and treated successfully by retracting it towards the abdominal aorta.

本病例报告突显了经导管主动脉瓣置换术（TAVR）的复杂性，即便术者经验丰富，有时罕见并发症仍难以避免。球囊扩张式人工瓣膜瓣环上脱位是由临时经静脉起搏器导线捕获失败所致，通过将其向腹主动脉回撤成功治愈。（）
