Hi @cturner01,
The watchman device is used to close off the heart’s left atrial appendage (LAA). It can be an alternative to blood thinners, but it's main function is to prevent blood clots from being thrown from the LAA that would cause a stroke in people with AFib. Overall it does not prevent AFib from happening.

Here is a good article that explains it in detail. https://www.umcvc.org/conditions-treatments/watchman-device-treating-atrial-fibrillation-afib

@cturner01, do you currently have AFib?
