Overview of study design including total number of study patients undergoing elective CMP-IV with full box lesion set for symptomatic AF (n = 853). Primary outcome was incidence of first ATA recurrence. By competing risk analysis, the estimated incidence of first ATAs recurrence was 11%, 18%, 23%, 30% and 35% at 1, 3, 5, 8, and 10 years, respectively. At 10 years, the survival in those who remained in sinus rhythm was 84% versus 77% in those who experienced at least 1 ATA recurrence (log-rank test, P = .03). Overall, the CMP-IV had excellent efficacy at maintaining sinus rhythm during the 10 years of follow-up. CMP-IV, Cox-Maze IV procedure; PVI, pulmonary vein isolation; SA, surgical ablation; AF, atrial fibrillation; ATA, atrial tachyarrhythmia.
