The purpose of this study was to provide an updated worldwide report on the methods, efficacy, and safety catheter ablation atrial fibrillation (AF).A questionnaire with 46 questions sent 521 centers from 24 countries in 4 continents. Complete interviews were collected 182 centers, which 85 reported have performed 20,825 procedures 16,309 patients AF between 2003 2006. median number per center 245 (range, 2 2715). All included paroxysmal AF, 85.9% also persistent 47.1% long-lasting AF. Carto-guided left circumferential (48.2% patients) Lasso-guided ostial electric disconnection (27.4%) most commonly used techniques. Efficacy data analyzed representing unit analysis. Of full disclosure outcome data, 10 488 (median, 70.0%; interquartile range, 57.7% 75.4%) became asymptomatic without antiarrhythmic drugs another 2047 (10.0%; 0.5% 17.1%) presence previously ineffective over 18 3 24) months follow-up. Success rates free overall success significantly larger 9590 (74.9% 83.2%) than 2800 (64.8% 75.0%) 1108 (63.1% 72.3%) (P<0.0001). Major complications 741 (4.5%).When a large electrophysiology laboratories worldwide, shows be effective approximately 80% after 1.3 patient, 70% them not requiring further during intermediate
