Figure 3. Estimation of the probability of atrial tachyarrhythmias (ATAs) recurrence within ten years based on length of time in atrial fibrillation prior to Cox-Maze IV (red dashed line) with 95% confidence intervals (solid blue lines).
Table 1: Baseline Patient Characteristics. For patients that had follow-up of at least 6 months or longer postoperatively, characteristics were compared across rhythm outcomes. There were no significant differences between groups by freedom from versus recurrence of ATAs for any of these variables (alpha = 0.05).
