Asymptomatic migration of an AMPLATZER ™ Amulet™ left atrial appendage occluder through the mitral valve

An 84‐year‐old woman with a history of hemorrhagic stroke was admitted for a new cerebral ischemic event. While in hospital, she was diagnosed with paroxysmal atrial fibrillation. Owing to her high thromboembolic risk (CHA2DS2‐VASc score of 6) we performed left atrial appendage (LAA) closure using a 22‐mm AMPLATZER™ Amulet™. The procedure was successful. Systematic follow‐up with transthoracic echocardiography 8 hr later revealed that the LAA occluder had migrated and become entrapped in the mitral subvalvular apparatus. At this time, the patient was asymptomatic. The device was recovered percutaneously using a loop‐snare catheter, with no further complications. © 2016 Wiley Periodicals, Inc.
