Left Atrial Appendage Closure Device (WATCHMAN™)

The WATCHMAN™ left atrial appendage closure device is used to decrease stroke risk in patients with atrial fibrillation without having to use blood thinners. The device is implanted in a hospital setting, followed by overnight observation. For more information on the WATCHMAN device, watch the video below.

St. Luke's Hospital is the first healthcare network in the St. Louis region to perform a commercial implant of the newly FDA-approved WATCHMAN FLX™ device.
This next generation permanent heart implant is a catheter-based, non-surgically delivered device designed to close the left atrial appendage. The procedure works to increase safety by reducing the risk of stroke in certain patients with atrial fibrillation.
