What is the left atrial appendage?

The left atrial appendage is a small sac-like extension of the left atrium or upper part of the heart. Atrial fibrillation patients may have blood pool in the left atrial appendage which may cause a blood clot to form and travel throughout the body and possibly cause a stroke.

Left Atrial Appendage Closure

The WATCHMAN procedure and left atrial appendage closure device is a first-of-its-kind, proven alternative to commonly-used blood thinner warfarin to prevent stoke in patients with atrial fibrillation or an abnormal heart beat. 

The WATCHMAN implant device is about the size of a quarter and shaped like a parachute. It is implanted into the heart to close off the left atrial appendage (LAA), a blind pouch of heart tissue to prevent blood clots from forming and causing a stroke.

The device is inserted into the heart through a catheter placed into a vein in the leg during a one-time, minimally invasive procedure. By closing off the LAA, patient’s risk of stroke is reduced and it may probably over time allow them to stop taking warfarin, xarelto, eliquis, pradaxa, etc.

WATCHMAN FLX

Built on the most studied and implanted LAAC device in the world, WATCHMAN FLX is designed to advance procedural performance and safety while expanding the treatable patient population
