Concomitant surgical left atrial appendage occlusion prevents strokes in patients with AF Removal or occlusion of the left atrial appendage during cardiac surgery has been hypothesized to prevent thromboembolic events in patients with atrial fibrillation (AF). To confirm this hypothesis, a team of researchers around the world conducted a multicentre, randomized trial involving 4811 participants with atrial fibrillation who were scheduled to undergo cardiac surgery for other reasons. Watch the an

Which of the following statements about LAAO is false? A. The primary source for thromboemboli in AF is the left atrial appendage, which is the rationale for LAAO B. LAAO should be considered in patients with AF who have an indication for anticoagulation but cannot take long-term anticoagulation C. The WATCHMAN device is the most
