WATCHMAN Gone Astray, Catastrophic Mitral Regurgitation Following Device Dislodgement.

WATCHMAN (Boston Scientific, Plymouth, MN, USA) is the most commonly utilized left atrial appendage occlusion device. Although increased operator experience has led to a significant decline in reported complications, serious and potentially fatal events can still occur. We present a case of WATCHMAN device embolization that was identified using transesophageal echocardiography shortly after device deployment, along with the subsequent management and retrieval of the device.
