How long does the WATCHMAN device last in the body?

The WATCHMAN device is designed to be a permanent implant within the body, intended to provide ongoing stroke prevention by sealing off the left atrial appendage. The FDA approved its use in 2015, but it has been commercially available internationally since 2009. During this time, its long-term durability has been studied and established to offer sustained effectiveness in reducing the risk of blood clot-related strokes in individuals with atrial fibrillation.

How big is the WATCHMAN implant?

The WATCHMAN device is typically around 2.5 to 3.5 centimeters (1 to 1.4 inches) in size. Its compact design allows it to be delivered and positioned within the left atrial appendage of the heart using minimally invasive catheter-based techniques, reducing the risk of blood clot-related strokes in individuals with atrial fibrillation.

How does the WATCHMAN device stop blood clots?

The WATCHMAN device prevents blood clots by effectively sealing off the left atrial appendage (LAA), a small pouch in the heart where clots often form in individuals with atrial fibrillation. Once implanted, the device forms a barrier, blocking the LAA and preventing clots from escaping into the bloodstream and causing strokes. This reduces the risk of blood clot-related strokes in patients with atrial fibrillation.

Is the WATCHMAN device a minimally invasive procedure?

Yes, the WATCHMAN device procedure is minimally invasive. It involves the insertion of a catheter through a blood vessel, typically in the leg or groin, and the device is guided to the heart using imaging techniques. This approach reduces the need for traditional open-heart surgery and often results in shorter recovery times and fewer complications.

What are the side effects of the WATCHMAN procedure?

The WATCHMAN procedure is generally well-tolerated, but like any medical intervention, it carries potential side effects. These can include a small risk of complications, such as bleeding, infection or anesthesia-related issues. Additionally, there might be a rare chance of device migration, blood clot formation or incomplete sealing of the left atrial appendage.

What is the difference between the WATCHMAN device and a pacemaker?

The WATCHMAN device is designed to reduce the risk of stroke in individuals with atrial fibrillation by sealing off the left atrial appendage and preventing blood clot-related strokes. A pacemaker, on the other hand, is an implant that helps regulate the heart’s rhythm by sending electrical signals to control its beating. While both are implanted devices, their primary functions and purposes differ – the WATCHMAN device focuses on stroke prevention, while a pacemaker addresses heart rhythm abnormalities.

WATCHMAN™

How Does the WATCHMAN™ Device Work? Atrial fibrillation (AFib) is a heart rhythm disorder in which the heart beats irregularly. During AFib, the two upper chambers of the heart (the atria) quiver instead of beating properly to effectively move blood into the heart’s two lower chambers (the ventricles). AFib can cause blood
