UT Health San Antonio physicians are using a new technique to treat atrial fibrillation, a common heart rhythm disorder and major risk factor for stroke.<\/figcaption><\/figure>\n

There\u2019s a new technique UT Health San Antonio physicians are using to treat atrial fibrillation, a common heart rhythm disorder and major risk factor for stroke.<\/p>\n

They are among the first in Texas trained to implant the Watchman\u2122 left atrial appendage closure device, which is approved by the Food and Drug Administration as a therapy for symptomatic, persistent atrial fibrillation.<\/p>\n

Atrial fibrillation, known as afib, affects around 6 million people in the United States. It is an irregular heartbeat that can result in very life-limiting symptoms for many patients. Although it occurs in both young and old people, the prevalence of afib increases with age. A serious consequence can be a stroke, which is up to five times more likely in patients with afib.<\/p>\n

\u201cAtrial fibrillation continues to be a very challenging problem to treat,\u201d said Steven R. Bailey, M.D., professor and chief of the Janey and Dolph Briscoe Division of Cardiology. \u201cThe prevalence of afib is growing, and there is no cure for the disease. However, it is hoped that studying new strategies may result in more effective ways of treating our patients who are struggling with afib. It is our goal to improve the quality of life of our patients and to limit the adverse events related to atrial fibrillation.\u201d<\/p>\n

The Watchman procedure closes a pouch called the left atrial appendage.<\/p>\n

\u201cAlthough the left atrial appendage is a small structure, it is believed to play an important role in the initiation of afib,\u201d said Manoj Panday, M.D., director of cardiac electrophysiology and an associate professor of medicine.<\/p>\n

The left atrial appendage is the source of up to 90 percent of strokes that are caused by afib.<\/p>\n

\u201cPatients have to be on lifelong blood thinner to reduce the risk of clots forming in that small area of the heart,\u201d Dr. Panday said.<\/p>\n

The Watchman device is delivered via a special catheter. The device is a self-expanding, nickel-titanium frame with an attached woven plastic cap that, when open, looks like a jellyfish. The device is positioned and then expanded to close blood flow to the left atrial appendage. Within six weeks endothelial tissue grows over the device, which remains for life.<\/p>\n

\u201cOnce implanted successfully, the device eliminates the need for long-term oral anticoagulation, which is especially important for those who are not eligible to have blood thinners,\u201d Dr. Panday said.<\/p>\n","protected":false},"excerpt":{"rendered":"
