Redo minimally invasive LAA closure with WATCHMAN device.

This video tutorial demonstrates the minimally invasive closure of a left atrial appendage (LAA) using the WATCHMAN device in a patient with a prior history of heart surgery. Given the failure of anticoagulation therapy, the decision was made to perform surgical closure of the LAA. Due to the patient's previous heart surgery, our standard LAA closure device, the AtriClip, could not be used. As an alternative, the WATCHMAN device was chosen. This device is FDA- and EMA-approved and is designed for implantation via a transcatheter-based approach.
