Case of successful transfemoral TAVR for pure aortic regurgitation in quadricuspid valve, highlighting procedural challenges.
We present a case of successful transfemoral transcatheter aortic valve replacement for a rare quadricuspid aortic valve with pure aortic regurgitation. Procedural challenges included identifying the annular plane, determining the appropriate deployment view, annular sizing, the absence of annular calcium, and the lack of a dedicated transcatheter device for pure aortic regurgitation.
