Paravalvular leak (PVL) is uncommon but can lead to severe complications after surgical or transcatheter aortic valve replacement. Clinical complications such as heart failure, haemolysis and infective endocarditis can be catastrophic results if not treated in promptly. It is, therefore, vital that PVLs are diagnosed early using various imaging modalities. Different approaches have been studies in managing PVL’s; of late, there is an increased interest in the use of minimally invasive procedures such as the transcatheter aortic valve closure procedure due to the decreased occurrence of further operations. This review discusses the classification of PVLs, diagnostic approaches and the available management options.
