2.5 Outcomes definitions
HPSD: Ablation power > 40 W, with shorter duration of 2~10s per site.
LPLD: Ablation power limited to 20~40W, with longer ablation duration of 10–30 s per site.
Procedure time: It is the time from the application of local anesthesia to the withdrawal of all catheters.
Ablation time: It is the time from the first to the last application.
Fluoroscopy time: It is the time of fluoroscopy from the start to the end of the procedure.
Atrial arrhythmias recrudescence: It is any symptomatic or asymptomatic atrial arrhythmia lasting >30 seconds after completing the blanking period after catheter ablation.
First-pass PVI: Rate of complete PVI after first pass circumferential radiofrequency delivery.
Major complications: It is defined as complications that required any intervention or prolonged hospital stay.
ETI: Endoscopy or MRI image were performed to assess esophageal thermal injury post-ablation.
