2. Fig. 1 Freedom of AF in subgroups.
Kaplan–Meier curve representing the percentage estimates of patients with freedom of AF up to one year after surgery. Panel A: freedom of AF curves for two participating centres (log-rank test p=0.45). Panel B: freedom of AF curves according to different types of AF (log-rank test p=0.70). Panel C: freedom of AF curves in left atrial diameter more or less than 45mm (log-rank test p=0.79). Panel D: freedom of AF curves stratified according to a history of previous catheter ablation (log-rank test p=0.69).
AF; atrial fibrillation, EP; electrophysiological, LA; left atrium, PVI; pulmonary vein isolation.
