Abstract

The transcatheter treatment of paravalvular leaks (PVL) are technically challenging procedures; they pose increasing difficulty in cases where there is a stentless valve, without the usual fluoroscopic landmarks. Hence, there is limited experience in treating this defect percutaneously. We present a case of a patient with an aortic PVL of a stentless valve and how the integrated use of multi-imaging modalities (transesophageal echocardiography, computed tomography and rotational angiography) allowed the demarcation of landmarks onto live fluoroscopy and guided the transcatheter occlusion of the PVL. © 2014 Wiley Periodicals, Inc.
