Percutaneous effective closure of severe aortic prosthetic paravalvular leak using Amplatzer duct occluder device with the guidance of 3D TEE.

Abstract

Aortic paravalvular leaks are well-known complications of prosthetic valve replacement. They are asymptomatic and small, but sometimes may cause symptoms due to severe regurgitation or hemolysis. Medical therapy is limited, while operation causes significant mortality. Percutaneous transcatheter closure techniques, potentially offer symptomatic relief. We describe the use of an Amplatzer duct occluder device with the guidance of 3dimensional transesophageal echocardiography (3DTEE) in a patient with severe aortic prosthetic paravalvular leak resulting in effective closure.
