In a national analysis of 19,524 patients with preoperative atrial fibrillation undergoing isolated coronary bypass grafting surgery (11,508 patients [58.9 percent]), left atrial appendage closure (4541 patients [23.3 percent]), or with concomitant ablation and left atrial appendage closure (3475 patients [17.8 percent]), concomitant left atrial appendage closure and ablation was associated with reduced stroke risk at three years (hazard ratio [HR], 0.74; P= .049) and improved survival (HR, 0.86; P= .016) compared with no concomitant atrial fibrillation procedure, and reduced stroke compared with left atrial appendage closure without ablation (HR, 0.75; P = .031).
