RESUMO
Atrial fibrillation (AF) is associated with a five-fold increased risk for stroke due to cardioembolic events. Most strokes in patients with AF arise from thrombus formation in the left atrial appendage (LAA). Oral anticoagulation is a standard treatment of AF patients with high risk of stroke. However, the main drawbacks of oral anticoagulation are high risk of major bleeding and imperfect effectiveness dependent on a very narrow therapeutic range. In this article, based on two case reports, we describe a method of percutaneous closure of the LAA. We discuss indications, describe the procedure and mention possible complications. LAA closure seems to be a promising tool to prevent AF-related strokes in a selected group of patients.
