Procedure characteristics
All patients underwent a PVI. Approximately 85% of the patients underwent a CTI block line ablation in both groups. There were no significant differences with regard to superior vena cava (SVC) isolation and other non-PV foci ablation between the two groups (Table 2).
Procedure time and total ablation time were significantly shorter in AI group than CF group. Total number of energy applications was smaller in AI group than CF group. There were no significant differences regarding procedural complication.
