Objective: To evaluate the initial safety and effectiveness of fluoroscopy-free atrial fibrillation ablation in a high-complexity center in Argentina. Method: Prospective, observational, single-center study at the Cardiovascular Institute of Buenos Aires, where 100 atrial fibrillation ablation procedures were performed without fluoroscopy between March and November 2024. Electroanatomical mapping (CARTO 3), intracardiac echocardiography, and specialized catheters were used to guide the procedures. Results: Complete pulmonary vein isolation was achieved in 100% of cases. The mean patient age was 63.5 years, with a male predominance (71%). Complications occurred in 3% of cases (two pericardial effusions and one post-procedural stroke). No esophageal or vascular complications were reported. Conclusions: Atrial fibrillation ablation without fluoroscopy in a high-complexity center is feasible, safe, and effective, reducing radiation exposure without compromising clinical outcomes.
