Abstract
Paravalvular leak (PVL) is a complication of valve replacement surgery due to incomplete apposition of the prostethis to the native tissue or to the homograft replacement. Most PVLs remain asymptomatic; however, 1-5% of the patients with prosthetic valves present clinically significant PVLs. Different percutaneous techniques with several devices have been explored for leak closure, but we are still lacking devices specifically designed to treat this pathology more effectively.<br>
