Left Atrial Appendage Occlusion Procedure

Left atrial appendage occlusion procedures are an innovative and preventative treatment for patients suffering from atrial fibrillation (A-fib), with the goal of mitigating the risk of stroke. This procedure, while not a treatment for A-fib, is often part of a treatment plan for patients suffering from arrhythmias, as arrhythmias of the heart can lead to other potential health risks. 

Why choose UPMC Heart and Vascular Institute for your left atrial appendage occlusion?

When you choose UPMC Heart and Vascular Institute for your left atrial appendage (LAA) occlusion procedure, you will receive expert care from some of the region's most experienced cardiologists. Our cardiologists are at the forefront of emerging LAA occlusion techniques and are participating in research to test new devices that have the potential to improve patient outcomes.

What is the left atrial appendage procedure?

The LAA of your heart is a pouch-like extension of the left atrium about the size of your thumb, with a narrow opening into the left atrium. If you have atrial fibrillation (A-fib), blood can pool and form clots in this appendage. If a blood clot breaks loose it may travel through your blood vessels and eventually plug a smaller vessel in your brain or heart, causing a stroke.

During the procedure, a small, fabric-covered device is permanently placed in the opening of your LAA to prevent harmful blood clots from exiting and entering your bloodstream. Within six weeks, the tissues of your heart grow over the device and "close off" the LAA from the rest your left atrium, which prevents the formation of blood clots.

Types of Procedures for Left Atrial Appendage Occlusion:

  • WatchmanTM
  • AmuletTM

What happens during the procedure?

LAA closure is performed under general anesthesia in the catheterization lab. Your doctor will insert a small catheter into an incision in your femoral vein in your upper thigh that is then guided to your heart. The device is delivered to the LAA through the catheter under x-ray and ultrasound guidance. The procedure takes about an hour.

How long does it take to recover after the Watchman procedure?

Recovery from the procedure is quick, so you should be able to resume your normal activities of daily living after about 24 hours. We recommend no heavy lifting and pulling for seven days. Your doctor will let you know when you can return to your normal activities and will schedule you for a follow-up appointment after your procedure.

You will need to continue taking Coumadin/warfarin (your doctor will prescribe a lower dosage) and daily aspirin for 45 days after your procedure. After 45 days, more than 95 percent of patients can stop Coumadin/warfarin and will stay on aspirin and Plavix for six months. After six months, most patients take only aspirin. It is important that you follow your doctor's instructions for taking your medication. You should not make any changes to your medications or dosages without first talking to your doctor.
