  Figure 3. Kaplan-Meier estimates of readmission of patients with nonparoxysmal atrial fibrillation undergoing coronary artery bypass grafting with or without surgical ablation. Freedom from readmission within 1 year was similar between groups (P = .3, long-rank test). Shaded areas represent 95% CI.

  Figure 5. Influence of surgical ablation of nonparoxysmal atrial fibrillation (AF) during coronary artery bypass grafting (CABG) on mortality and readmissions. From 2016 to 2018, 18,899 patients with nonparoxysmal AF underwent CABG. A total of 4123 (21.8%) underwent concomitant surgical ablation and 14,776 (78.2%) underwent isolated CABG. After propensity score matching, surgical ablation was not associated with increased length of stay, in-hospital mortality, or readmissions up to 1 year. SA, Surgical ablation.
