WATCHMAN offers an alternative to the lifelong use of warfarin for people with atrial fibrillation not caused by a heart valve problem (also known as non-valvular AFib).
This permanent heart implant effectively reduces the risk of stroke—without the risk of bleeding that can come with the long-term use of warfarin (the most common blood thinner). What’s more, WATCHMAN can eliminate the regular blood tests and food-and-drink restrictions that come with warfarin. (Warfarin is also known as Coumadin®.)
How it Works
To understand how WATCHMAN works, it helps to know more about the connection between atrial fibrillation and stroke.
Atrial fibrillation, or AFib, affects your heart's ability to pump blood normally. This can cause blood to pool in an area of the heart called the left atrial appendage, or LAA. There, blood cells can stick together and form a clot. When a blood clot escapes from the LAA and travels to another part of the body, it can cut off the blood supply to the brain, causing a stroke.
