Overall, 30 patients were enrolled in each group, with a standardized 12\u2010month follow\u2010up, free of antiarrhythmic therapy. Demographic, cardiovascular and anatomic characteristics were similar in both groups. Though complete PVI was eventually achieved in all cases in both groups, success using an exclusive anatomic approach was 80.0% in CF group versus 36.7% in control group (<jats:italic>P<\/jats:italic> &lt; 0.0001). CF use was associated with significant reductions in fluoroscopy exposure (<jats:italic>P<\/jats:italic> &lt; 0.01) and radiofrequency time (<jats:italic>P<\/jats:italic> = 0.01). The incidence rates of AF recurrence were 10.5% (95% CI, 1.38\u201322.4) in the CF group, and 35.9% (95% CI, 12.4\u201359.4) in the control group (log rank test, <jats:italic>P<\/jats:italic> = 0.04). After adjustment on potential confounders, the use of CF catheter was found to be associated with a lower AF recurrence (OR 0.18, 95% CI 0.04\u20130.94, <jats:italic>P<\/jats:italic> =
