When Echocardiography Is Challenging in Localizing Bioprosthetic Aortic Regurgitation: Dye Don't Lie.

Transesophageal echocardiography is the main imaging modality for localizing and quantifying prosthetic aortic regurgitation. We describe a case of bioprosthetic aortic paravalvular leak (PVL) where transesophageal echocardiography was inadequate; aortic root angiography and computed tomography fusion were critical in diagnosing and guiding closure. Multimodality imaging can be pivotal in localizing PVL and guiding transcatheter PVL closure. ( Level of Difficulty: Intermediate. ).
