If you have AFib, your chances of having a stroke significantly increase. The most common treatment for reducing your risk of stroke is blood-thinning therapy —Warfarin, Coumadin, Pradaxa, Xarelto, Eliquis. Unfortunately, not all patients can tolerate those drug therapies long-term. The physicians at St. Elizabeth Heart & Vascular Institute can help patients with AFib that is not caused by a heart valve problem who cannot tolerate long-term drug therapy by performing a procedure that blocks the source of blood clots that can cause strokes. The procedure is called left atrial appendage occlusion and it uses the Watchman device. The left atrial appendage is a small sac in the left atrium of the heart where blood can pool and clot, then break loose to cause a stroke. The Watchman device is a safe, effective way to close that sac so blood cannot pool and clot. The Electrophysiologists and Interventional Cardiologists at St. Elizabeth Heart & Vascular Institute perform this procedure in the Electrophysiology Lab at St. Elizabeth Edgewood. If you have questions about whether this procedure would benefit you, talk with your cardiologist.

The Watchman device is a small, fabric-covered device permanently placed in the opening of the left atrial appendage in the left atrium of your heart. The device is designed to permanently close off the left atrial appendage, the source of a majority of stroke-causing blood clots. Implanting the Watchman device is a one-time procedure that usually lasts about an hour and is conducted with general anesthesia. The Watchman device is implanted through a small incision at the top of your leg using a catheter. Following the procedure, patients will need to stay in the hospital for a minimum of 24 hours. The body takes approximately 45 days to heal and grow a natural lining over the device. After 45 days of healing, most patients can then discontinue the blood-thinners they were previously prescribed to lessen the risk of stroke. Who should consider a Watchman Device? The first treatment for anyone with AFib considered at high risk of stroke is the use of blood thinning drugs. The Watchman device is for those who can’t tolerate or are considered unsuitable for long-term drug therapy. You may not be suited for long-term blood-thinning therapy due to: High risk of falls or a history of falling. Lifestyle is incompatible with daily blood thinners such as a job with a high risk for cuts or injury. Complications from blood-thinning drugs such as gastrointestinal bleeding. The Watchman device has proven to be a safe an effective alternative to blood-thinning drug therapies.
