Abstract:
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.).

TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
