Transcatheter closure of an aorto-right ventricular fistula after TAVR

Percutaneous Treatment of an Aorto-Right Ventricular Fistula Following Balloon-Expandable Transcatheter Aortic Valve Replacement

We present the case of a 71-year-old man who experienced congestive cardiac failure after transcatheter aortic valve replacement with a balloon-expandable transcatheter heart valve. Echocardiography and cardiac computed tomography demonstrated an aorto-right ventricular fistula, and successful percutaneous closure was performed with a vascular plug. (Level of Difficulty: Advanced.).

Aortic Root Replacement for a TAVR-Induced Aortic Root-to-Right Ventricular Fistula

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.
