Study Summary

LAAOS-4 aims to determine if catheter-based endovascular left atrial appendage occlusion prevents ischemic stroke or systemic embolism in participants with atrial fibrillation, who remain at high risk of stroke, despite receiving ongoing treatment with oral anticoagulation.

Primary Outcome

The primary efficacy variable is the time from randomization to first occurrence of any of the components of the composite outcome (adjudicated) over the duration of follow-up, including: * Ischemic stroke (Strokes of undetermined etiology will be treated as ischemic stroke) * Systemic embolism
