Radiofrequency catheter ablation of atrial fibrillation (AF) is one the most complex procedures. Both patients and operators are exposed to scattered radiation. This study evaluated safety efficacy intracardiac echo (ICE)-guided pulmonary vein isolation (PVI) without fluoroscopy.We retrospectively analyzed data 481 consecutive with paroxysmal AF undergoing radiofrequency PVI CARTO 3 system (Biosense Webster, Diamond Bar, CA, USA). ICE-guided fluoroscopy CT/MRI integration (Nonfluoro group) was performed for 245 patients, conventional fluoroscopy-guided (Fluoro 236 patients. The primary endpoint incidence major adverse events. freedom from during follow-up. Secondary endpoints included procedure duration, acute rate.Mean times between groups were similar (108.8 ± 18.2 minutes in Non-fluoro group vs 113.6 26.8 Fluoro group; P = not significant [NS]). Acute achieved all mean application 43.4 7.5 44.4 10.7 Nonfluoro groups, respectively (P NS). cardiac tamponade 1.2% (3/245 patients) 0.8% (2/236 During 15.2 4.1 months follow-up, after a single procedure, recurrence documented 65 (26.5%) 61 (25.8%) NS).Nonfluoroscopic prior image or angiography feasible safe. did affect duration long-term efficacy.
