Three\u2010dimensional computed tomography was performed in all patients before the ablation. The clinical outcomes of the AF ablation between patients with (Group A) and without an LCPV (Group B) were compared. An LCPV was observed in 27 (8%) patients. There were no significant differences in the procedure time (149 \u00b1 45\u00a0min vs. 143 \u00b1 40\u00a0min, respectively; P = 0.42) and percentage needing touch up ablation between the 2 groups (26%\u00a0vs. 20%, respectively; P = 0.45). At a mean follow\u2010up of 454 \u00b1 195 days, 282 of 324 (87%) patients were free from any atrial tachyarrhythmias (ATs) after a single procedure.
