Successful retrieval of a dislodged left atrial appendage occlusion device using an ONO basket: A case report

Left atrial appendage occlusion (LAAO) is an alternative to anticoagulation for atrial fibrillation patients at high thromboembolic risk, but device embolization, though rare, can be life-threatening and may require percutaneous retrieval or surgery. We present the case of an 82-year-old male who underwent successful Watchman device implantation for stroke prevention; however, follow-up echocardiography revealed embolization into the left ventricular outflow tract (LVOT), necessitating urgent retrieval. The device was safely removed percutaneously using an ONO basket without complications, and the patient later underwent successful repeat LAA closure with an Amulet device, confirmed by transesophageal echocardiography (TEE). This case highlights the feasibility of percutaneous retrieval using an ONO basket, the importance of early detection of device embolization, and a minimally invasive approach that allows for subsequent successful LAA closure.
