Discussion
AF is one of the most common cardiac arrhyth- mias (1–2% in Western countries) [4]. More than 15% of cerebral ischemia cases are related to AF [5]. Almost 90% of atrial thrombi are formed in the LAA in patients with nonvalvular AF [6]. Systemic antico-

agulation is the therapy of choice to reduce the risk of thromboembolism in AF, but studies have shown that only few patients receive such therapies de- spite being indicated for multiple reasons, including complications and noncompliance [7]. Considering these limitations, percutaneous closure of the LAA is becoming increasingly popular in selected patients.
