Key result
Preoperative atrial fibrillation was independently associated with reduced mid-term survival after concomitant AVR-CABG surgery (HR 1.58; 95% CI 1.14-2.19; P=0.006).

Preoperative atrial fibrillation is an independent risk factor for reduced mid-term survival after concomitant AVR-CABG surgery, suggesting these patients should be considered for concomitant surgical ablation.
Saxena et al. (2013) conducted a cohort in Concomitant aortic valve replacement and coronary artery bypass graft (AVR-CABG) surgery (n=2,563). Preoperative atrial fibrillation vs. No preoperative atrial fibrillation was evaluated on mid-term mortality (HR 1.58, 95% CI 1.14-2.19, p=0.006). Preoperative atrial fibrillation was independently associated with reduced mid-term survival after concomitant AVR-CABG surgery (HR 1.58; 95% CI 1.14-2.19; P=0.006).
