Left Atrial Appendage Closure

Medically reviewed by Drugs.com. Last updated on Jun 5, 2024.

Left atrial appendage closure (LAAC) is a procedure to block or close the left atrial appendage. The appendage is a small pouch in the heart muscle that is connected to your left atrium. Blood clots may form in the appendage if you have atrial fibrillation. This increases your risk for stroke. LAAC helps prevent blood clots from entering your bloodstream and lowers your risk for stroke.
