Introduction: Radiofrequency catheter ablation of atrial fibrillation is performed under fluoroscopic guidance and therefore carries radiation risk exposure for the both the patient and the operator. Three-dimensional mapping systems and newer technologies to allow non-fluoroscopic catheter visualization together with intracardiac echo have reduced but not abolished the fluoroscopy exposure. We aim to demonstrate the feasibility, the safety and the efficacy of catheter ablation for atrial fibrillation without the use of fluoroscopy. Methods: A totally fluoro-less approach was developed for AF ablation at our Institution. 94 consecutive AF patients underwent zero fluoroscopy catheter ablation for atrial fibrillation. In the zero fluoroscopy cases, the fluoroscopy arm was kept far away from the patient table. Access including double trans-septal, mapping with the Carto 3 system and ablation were all performed without fluoroscopy with the use of ICE and the Carto 3 system. These 94 patients were compared with 94 control patients matched for age, sex and type of AF who underwent AF ablation by the same operator with the use of fluoroscopy. Results: Baseline characteristics were similar between fluoroless (N=94, Age=64.5 ± 10.1, 75.5% male, 48% paroxysmal) and control (N=94, Age=65.1 ± 9.9, 72.3% male, 50% paroxysmal) group. Non-PV triggers were detected and ablated in 51 (54.3%) and 56 (59.6%) patients in fluoroless and control group respectively (p=0.5). Average fluoro time in control group was 10.1 ± 4.7 minutes. Procedure duration was comparable (120.4 ± 25.8 vs. 122.2 ± 28.7, p =0.6). After the short term median follow-up of 4.5 (4 – 6.5) months, 10 (10.6 %) patients in flourless and 9 (9.6%) patients in control group experienced recurrences (p=0.8).One pericardial effusion requiring pericardiocenteis occurred in the fluoroless group. Conclusions: Our series show that zero fluoroscopy ablation of atrial fibrillation with the use of newer technologies is feasible, safe and efficacious at the short term follow up. Importantly in our series the double transeptal was performed without fluoroscopy and the ablation was not limited to the pulmonary veins only but included ablation of the posterior wall, the coronary sinus and the left atrial appendage.
