Why the study?
The study was conducted to investigate the distribution of triggers in PAF patients and assess the efficacy of CPVI combined with non-PV trigger ablation over 1 year.

May support adjunctive non-PV trigger ablation in paroxysmal AF; hypothesis-generating and requires randomized confirmation before practice change.
Does CPVI combined with non-PV trigger ablation improve 1-year success rates in patients with paroxysmal atrial fibrillation?
Identifying and ablating non-PV triggers, particularly in the superior vena cava, in addition to CPVI, yields high 1-year success rates and significantly reduces postoperative recurrence in PAF patients.
