Left Atrial Appendage Occlusion

More than 10.5 million Americans suffer from atrial fibrillation (AF): the irregular, chaotic beating of the upper chambers of the heart. And, the American Heart Association predicts that more than 12 million Americans will be affected by AF in 2030. AF increases your risk of stroke five times over someone with a normal heart, and most people with AF need long-term treatment to reduce the risk of a stroke.

Taking oral blood thinners is the most common course, but they come with complications. You may have increased risk of bleeding, negative interactions with some foods and drugs, and side effects that can be severe.

Since over 90% of strokes in people with AF originate in the heart's left atrial appendage (LAA), a left atrial appendage occlusion procedure can be a good alternative over long-term anti-clotting drugs. The procedure closes off the atrial appendage with permeable mesh (such as a WATCHMAN® device) that prevents clots from forming and entering the blood stream.

Studies show that after a successful procedure, the risk of stroke can be reduced to the levels of a person with a normal heart. The procedure has been shown to be as effective as blood thinners at preventing stroke. Continuing blood thinner medications are part of the recovery period, and aspirin is recommended for at least one year, depending on your individual circumstances.
