About the procedure
How to reduce the risk of stroke

Left atrial appendage exclusion is a nonsurgical procedure used to reduce the risk of stroke in patients with atrial fibrillation. The left atrial appendage is a muscular pouch attached to the left atrium of the heart. In patients with atrial fibrillation, a high number of blood clots (up to 90%) form in the left atrial appendage. These blood clots increase the risk of stroke. The usual treatment involves using blood thinners to thin the blood and increase blood flow. In patients who cannot take blood thinner medications, the left atrial appendage can be permanently sealed off, or excluded, from the rest of the heart with left atrial appendage exclusion. This procedure eliminates the appendage from circulation and potentially decreases the risk of stroke in patients with atrial fibrillation.

Why it’s done

If you have atrial fibrillation but cannot take blood-thinning medications, your doctor may recommend left atrial appendage. This procedure seals off, or excludes, the left atrial appendage of the heart, which helps prevent blood clot formation and thereby reduces the risk of stroke.

What to expect

Preparation: Your doctor will give you specific instructions on how to prepare for your procedure.

During: Left atrial appendage exclusion is a minimally invasive, nonsurgical procedure. You will be given general anesthesia during the procedure. Your cardiologist will use special catheters to place a loop around the atrial appendage and seal it off.

After: There is minimal discomfort after this procedure. You can return to your normal routine as soon as you are ready.
