Aortic right ventricular fistulae have been thoroughly documented as a rare but potentially serious complication of surgical aortic valve replacement. The risk factors and pathogenesis contributing to this complication with respect to transcatheter aortic valve replacement (TAVR), however, remain far less characterized. We describe a post-TAVR aortic root-to-right ventricular fistula with associated pseudoaneurysm requiring surgical aortic root replacement.
升主动脉-右心室瘘是主动脉瓣置换术的一种罕见但潜在严重的并发症,已有充分的记载。然而,关于经导管主动脉瓣置换术(TAVR)导致这种并发症的危险因素和发病机制仍远未得到充分描述。我们描述了一例 TAVR 后出现的升主动脉-右心室瘘并伴有假性动脉瘤,需要行主动脉根部置换术。
