We included 304 consecutive patients undergoing CA for PAF (209 males, aged 63.0 +/- 10.4 years). We divided the patients into 3 groups: group 1 comprised 245 patients without any inducible non-PV triggers; group 2 comprised 34 patients with AF originating from non-PV triggers with all non-PV triggers successfully ablated; and group 3 comprised 25 patients with AF originating from non-PV triggers with unsuccessful complete elimination of the non-PV triggers, and inducibility of AF or frequent ectopic beats still present. The mean follow up period was 26.9 +/- 11.8 months, and we compare the recurrence rate of AF after the last procedure.
