The annual incidence of stroke in patients with nonrheumatic atrial fibrillation averages 5% per year and increases with age, left ventricular dysfunction, hypertension, diabetes or prior stroke. Since in nonrheumatic atrial fibrillation 91% of left atrial thrombi are located in the left atrial appendage, in patients ineligible for oral anticoagulation it was suggested the percutaneous closure of left atrial appendage as a therapeutic option to reduce embolic risk. In this article we report our initial experience with this procedure, which was uneventful and efficacious at short-term follow-up. In conclusion, the interventional approach in patients with atrial fibrillation ineligible for oral anticoagulation seems feasible and promising, and deserves further investigation.

Abstract
The annual incidence of stroke in patients with nonrheumatic atrial fibrillation averages 5% per year and increases with age, left ventricular dysfunction, hypertension, diabetes or prior stroke. Since in nonrheumatic atrial fibrillation 91% of left atrial thrombi are located in the left atrial appendage, in patients ineligible for oral anticoagulation it was suggested the percutaneous closure of left atrial appendage as a therapeutic option to reduce embolic risk. In this article we report our initial experience with this procedure, which was uneventful and efficacious at short-term follow-up. In conclusion, the interventional approach in patients with atrial fibrillation ineligible for oral anticoagulation seems feasible and promising, and deserves further investigation.Pubblicazioni consigliate
