Abstract:
We report a case of successful 2-stage percutaneous closure of severe paravalvular leak (PVL) in a patient with stentless aortic bioprosthesis. Threat of pliable prosthesis compression and long course of PVL posed main considerations. Accordingly, Amplatzer vascular plug (AVP) 2 was chosen as occluder. It was delivered transfemorally under fluoroscopy and transesophageal echocardiography guidance. No prosthesis distortion was provoked at the expense of moderate residual leak. Its symptoms after 3 months spurred another AVP 2 implantation, which lead to PVL closure with no effect on valve area. Marked reduction of left ventricle cavity size and NT-proBNP plasma concentration was promptly noted and remains stable in 12-month follow-up.
