Findings after the second session
Among the CF group patients with ERAT, 70 patients underwent a second session of CA for late recurrences of AF, whereas 24 patients underwent second sessions among those in AI group. The rate of a PV reconnection was lower in AI group than CF group (45.8% vs. 71.4%, P=0.028, Figure 3). In the analyses of each PV, the percentage of right superior PV (RSPV) reconnections were significantly lower in AI group than CF group (20.8% vs. 48.6%, P=0.029).
