What is a watchman in cardiology? 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.
What is watchman and how does it work? The WATCHMAN device is implanted inside the LAA. By closing off the left atrial appendage, blood clots that form within the LAA are prevented from entering the bloodstream. The WATCHMAN device has been shown in clinical trials to provide comparable effectiveness in stroke prevention to warfarin.
How serious is the watchman surgery? Although the procedure is minimally invasive and effective, some people may experience complications during or following the procedure. Risks and complications associated with the Watchman procedure include: Cardiac tamponade. Accidental heart puncture.
Is the watchman a blood clot filter? WATCHMAN™ implant
The device is designed to essentially act as a mesh filter, allowing blood to flow through while stopping clots. We have more experience with this minimally invasive procedure than anyone else in the mid-Atlantic region.
