About this study

Atrial fibrillation (AF) is progressively common, and increases the risk of stroke five-fold. Oral anticoagulation is the mainstay therapy; however, it increases the risk of bleeding. Moreover, 30% with AF and at risk of stroke are not in relevant anticoagulation. The randomized PROTECT-AF trial has demonstrated the superiority of left atrial appendage occlusion (LAAO) as compared to warfarin for prevention of the combined endpoint of stroke, major bleeding and cardiovascular mortality. However, studies comparing LAAO to therapy with novel oral anticoagulants (NOAC) have not been carried out. This study aims to assess the effect of left atrial appendage occlusion (LAAO) to reduce the incidence of stroke, systemic embolism, major bleeding and all-cause mortality in patients with atrial fibrillation (AF) and a prior ischemic stroke or transient ischemic attack (TIA).
