Brief Summary

The APPENDAGE study is a phase 4 multicentre randomized opened clinical trial comparing 2 different antithrombotic strategies following left atrial appendage closure (LAAC) in patients with non valvular atrial fibrillation (AF). The primary objective of the study is to evaluate the efficacy of Aspirin versus Aspirin + Clopidogrel after LAAC by comparing the occurrence of ischemic lesions on cerebrovascular magnetic resonance imaging (MRI) studies.
