Three-Dimensional Echocardiographic Imaging of a Gerbode Defect Complicating Transcatheter Aortic Valve Replacement.


ABSTRACT: We describe a case of a 77-year-old male who underwent transcatheter aortic valve implantation (TAVR) with Edwards SAPIEN XT size 26 mm for severe aortic stenosis. Postprocedural transesophageal echocardiography (TEE) showed left-to-right shunt between the left ventricular outflow tract just below the bioprosthesis and the right atrium across the atrioventricular septum (Gerbode defect). Three-dimensional echocardiography (3DE) allowed a detailed anatomical imaging of the shape and the location of a small, circular, atrioventricular defect that was a type II, direct, supravalvular, Gerbode-type defect. This is the third report of a Gerbode defect after TAVR whose diagnosis has important implications on clinical decision-making. TEE plays a key role; its diagnostic ability is enriched by the additional value of 3DE.
