Left Atrial Appendage Occluder Device

If you suffer from atrial fibrillation not due to a heart valve problem, you don't have to travel far for innovative heart treatment.

The left atrial appendage is a sac located in the left upper chamber of the heart – this chamber is called the left atrium. Atrial fibrillation is an irregular heart beat. This can cause blood to get trapped in the LAA and form a clot. When the blood clot gets pumped out of the heart, it can cause a stroke.

A left atrial appendage occluder device may be the best option for you. It does not require open-heart surgery and permanently closes off the LAA so blood clots don't form. The experienced team at Bronson Methodist Hospital uses the WATCHMAN Implant to close off the LAA. It is the only device on the market that is approved by the Food and Drug Administration.
