Abstract:
BACKGROUND:Left atrial appendage (LAA) ligation with the Lariat device is a therapeutic option to prevent thromboembolic stoke in patients with nonvalvular atrial fibrillation (AF) at high risk for systemic thromboembolization and bleeding related to use of anticoagulation. In rare cases, this procedure could leave the LAA incompletely ligated with continued risk of stroke. OBJECTIVE:The purpose of this study was to investigate the incidence and characteristics of LAA leak following ligation using the Lariat device and the feasibility of leak closure with the Amplatzer septal occluder device or a repeat Lariat application. METHODS:Seventy-one consecutive patients who underwent LAA ligation by the Lariat device were followed-up with transesophageal echocardiography to evaluate for the presence of appendage leaks, characterization of the leaks, and the presence of any thrombus. Patients with LAA leaks underwent definite closure of the leak. RESULTS:Six patients had LAA leaks with a mean leak size of 4.3 ± 0.6 mm. All leaks were concentric in nature. None of the patients had LAA thrombus. Leaks in 5 of these patients were successfully closed using an Amplatzer septal occluder device (St. Jude Medical); the leak in the sixth patient was closed using a repeat Lariat procedure. CONCLUSION:LAA leaks from incomplete ligation of the LAA following the Lariat procedure are not uncommon and could be successfully closed with an Amplatzer septal occluder device or a repeat Lariat procedure.
