Transcatheter closure using devices like Amplatzer occluders is described as an option for patients with paravalvular leaks who are poor surgical candidates.
Paravalvular leak occurs in about 2–3% of patients after surgical valve replacement. The leak may cause heart failure, arrhythmias, or hemolysis. Patients who have had multiple operations or who have significant comorbidity constituting a contraindication to surgery might be considered candidates for transcatheter closure. In the past, occluding paravalvular leaks has been attempted using coils or double umbrella devices; defect specific devices are under development. Interventional experiences with various Amplatzer occluders are described.
