Cardia, Inc. - LAA Information

What is a LAA?

Your heart is made up of four chambers -- the left and right atrium along with the left and right ventricles. The left atrial appendage, or LAA, is a pocket-like section that is actually part of the left atrium.

As your heart beats, the chambers of the heart contract and expand, pushing blood through your heart and out to the body. If you suffer from atrial fibrillation, a disorder that can prevent your left atrium from contracting fully, blood can pool in the LAA and form a clot. The blood clot(s) can then break free and travel through your body, possibly reaching your brain and causing a stroke.

The Ultrasept LAA is designed to close this pouch quickly, safely, and non-surgically. In most cases, patients are admitted to the hospital in the morning and return home that evening or the following day.
