What is the Watchman device used for?
The Watchman device is a plug-style device placed in the ostium of the left atrial appendage to occlude it and prevent thromboembolism. It is the only currently available device with US Food and Drug Administration approval for left atrial appendage closure, and is currently used in combination with short-term oral anticoagulation after placement to reduce the risk of device-related thrombus followed by 4.5 months of DAPT.
