Abstract

Rarely, a left atrial appendage closure device may chronically migrate to an unfavorable position postoperatively, requiring removal. We present the details of a case in which a WATCHMAN™ device (Boston Scientific, Natick, MA, USA) implanted seven months prior was found to have migrated with protrusion 0.91 cm outside the left atrial appendage together with a 90º tilt and peridevice leakage. Adopting a femoral arterial retrograde approach, a 27-mm WATCHMAN™ device was temporarily positioned in the ascending aorta for cerebroembolic protection, never released from the connecting wire. Extraction of the original WATCHMAN™ device was performed using an endoscopic grasping tool, with subsequent device re-implantation of a new device and removal of the temporarily positioned device in the ascending aorta.
