Left atrial appendage (LAA) occlusion or ligation is a novel approach to stroke prevention in atrial fibrillation that may obviate the need for long-term anticoagulation. The Lariat device has received Food and Drug Administration 510K clearance for the approximation of soft tissue and has been applied to transcatheter LAA ligation using a combined trans-pericardial and transseptal approach. The occurrence of late leak after transcatheter LAA ligation and its percutaneous management has not been previously reported. Herein, we report three cases of late leak with reconstitution of the LAA after initially successful Lariat closure, and present a simple percutaneous technique for leak closure. © 2013 Wiley Periodicals, Inc.
