Transcatheter therapy is a viable option for treating surgical prosthetic paravalvular leaks, with multi-modality imaging playing a key role in diagnosis and treatment.
May support transcatheter closure in select patients; leaves open need for prospective trials on durability and selection.
Paravalvular leak (PVL) is an uncommon yet serious complication associated with surgical prosthetic valve implantation. Paravalvular leak can have significant clinical consequence such as congestive heart failure, haemolytic anaemia, and infective endocarditis. Recently, transcatheter therapy has been applied to the treatment of this disorder with reasonable procedural and clinical success. This review discusses the current state of PVLs, the utilization of multi-modality imaging in their diagnosis and treatment, and the available therapeutic options. Further aim of this review is to examine transcatheter therapy of PVLs including the principles, outcomes, and procedural-related complications.
