Abstract

Abstract: Background: Embolization of a Watchman device in patients undergoing percutaneous left atrial appendage (LAA) closure is a rare complication. Retrieval of the device can be achieved percutaneously with a snaring technique or a bioptome. Case summary: We present an illustrative case of Watchman closure device embolization during an LAA closure attempt in a 77-year-old man. The complication was caused by anatomical restraints of the LAA, in particular limited depth resulting in poor stability of the closure device after implantation. By the use of a double snaring technique, however, we managed to retrieve the device percutaneously. By applying such strategy, a more invasive surgical approach can be prevented. Discussion: Prompt response is needed when embolization of a Watchman device occurs. A snaring technique can be used in most cases to attempt device retrieval. A double snaring technique is in this case associated with higher retrieval success than a single snaring technique.
