206

Results

A total of 98 patients were assigned to the mapping-guided group and 102 to the PVI alone group. Freedom from AF/atrial tachycardia without antiarrhythmic drugs at 2-year follow-up was 66.8% and 75.2% in the mapping-guided ablation and the PVI alone groups, respectively (hazard ratio 1.26 [95%CI 0.76-2.10], p=0.37).

Baseline Characteristics

200 patients undergoing their first catheter ablation for persistent or longstanding persistent AF were enrolled.
The mean age was 66.4 years and 66.8 years in the mapping-guided and the PVI alone groups, respectively.
Male was 81.6% and 82.4% in the mapping-guided and the PVI alone groups, respectively.

Participant flow

Screening was performed on 397 patients, 206 of whom agreed to participate in this study.
After randomization, 4 patients were excluded.

Adverse events

Adverse events occurred in 3 patients and none in the mapping-guided ablation and the PVI alone groups, respectively (p=0.12).

Outcome measures

Freedom from AF/AT without antiarrhythmic drugs beyond a 3-month blanking period.
