Atrial fibrillation is the most common arrhythmia which affects 1% of general population. Ischemic stroke, as a thromboembolic complication, is 5-7 times more common in patients with nonvalvular atrial fibrillation in relation to general population and affects 23.5% of patients older than 80 years with more severe consequences then in patients with sinus rhythm.

Oral anticoagulants, varfarin and novel generation drugs, despite being the standard in treatment are low tolerable or contraindicated in some patients in which percutaneous left atrial appendage closure can be a method of choice in reducing the incidence of ischemic stroke.
