CHICAGO — In the BRAIN-AF trial, daily rivaroxaban did not reduce the incidence of cognitive decline, stroke or transient ischemic attack, compared with placebo, among younger patients with atrial fibrillation and low stroke risk.

CHICAGO — In the OPTION trial, left atrial appendage closure resulted in similar thromboembolic protection but superior bleeding outcomes compared with oral anticoagulation among patients who underwent ablation for atrial fibrillation.
