Figure 2. Outcomes of biatrial arrhythmia surgery (upper panel) and right‐sided arrhythmia surgery (lower panel).

Figure 2

Forest plot of the proportions of patients with arrhythmia recurrence and corresponding 95% CIs. The overall median and interquartile range of proportions are displayed in red. AF/MRAT indicates that both arrhythmias were regarded as indication: outcomes of arrhythmia surgery were not further specified according to the type of preoperative arrhythmia. AR indicates atrial fibrillation; IQR, interquartile range; and MRAT, macroreentrant atrial tachycardia; *Outcome measure: recurrence of preoperative arrhythmia or other atrial tachyarrhythmias (not specified). †Outcome measure: recurrence or on anti‐arrhythmic drugs. ‡Partially duplicate data but studies also contain a significant amount of unique data. §Including n=22 patients with exclusive isthmus ablation; outcomes not specified. ||Including n=9 patients with exclusive isthmus ablation; outcomes specified in text. #Right atrial compartment or isolation techniques applied. **Number of patients at start of study. ¤Separate outcomes only available in sub‐analysis at 1 year follow‐up. »Follow‐up not specified for subgroup.
