Watchman Implant

The Watchman implant, a minimally-invasive left atrial appendage closure (LAAC) treatment that gives patients with non-valvular AFib an alternative to long-term warfarin medication. This one-time procedure is an important option for people with a history or risk of serious bleeding on blood thinners.


How does it work?

People with AFib are at increased risk of stroke, mainly due to blood clots that form in the left atrial appendage, a small sac in the top left chamber of the heart. Watchman is a treatment that reduces the risk of blood clots from entering the bloodstream and causing a stroke in patients with non-valvular AFib.

Watchman implant

During the Watchman procedure, a flexible tube is guided through the veins of the leg to the left atrial appendage. When the Watchman device is deployed, it closes off the appendage and is left permanently fixed in the heart. The Watchman device does not need to be replaced and does not require open heart surgery. The procedure typically takes one and a half hours and patients recover in the hospital for 24 to 48 hours.
