Background: We questioned whether the empirical four pulmonary vein (PV) isolation
(EmPVI) was necessary in patients with paroxysmal atrial fibrillation (PAF) triggered from
clearly and reproducibly defined arrhythmogenic PVs. Methods: We compared the selective
or ipsilateral isolation of the PVs triggering AF (SePVI: n= 42) and EmPVI (n= 35) in 77
patients (males 80.5%, mean age 53.0±13.4 years) with PAF who underwent radiofrequency
catheter ablation (RFCA). Arrhythmogenic PVs were identified by the immediate recurrence …
