Why the study?
To understand the anatomical and surgical principles of surgical left atrial appendage occlusion during cardiac surgery and evaluate the evidence supporting its indication.
Does surgical occlusion of the left atrial appendage during cardiac surgery reduce the risk of stroke and systemic embolism in patients with atrial fibrillation?

Pedro Rojas (2024) conducted a review in Atrial fibrillation in patients undergoing cardiac surgery. Surgical left atrial appendage closure (amputation and suture, endoatrial closure, or epicardial clipping) vs. No left atrial appendage occlusion during cardiac surgery was evaluated on Ischemic stroke or systemic embolism (highlighted from LAAOS III) (HR 0.67, 95% CI 0.53-0.85, p=0.001).
