D-PO02-132 - Safety And Efficacy Of Minimal Vs. Zero Fluoroscopy Radiofrequency Catheter Ablation For Atrial Fibrillation: A Multicenter Prospective Study (ID 1023)


Background: Radiofrequency catheter ablation (CA) is effective treatment for atrial fibrillation (AF). CA typically requires fluoroscopy to guide catheter manipulation and positioning. Advances in electro-anatomical mapping (EAM) technology and intracardiac echocardiography (ICE) have reduced reliance on fluoroscopy.
Objective: Determine safety and efficacy of zero fluoroscopy AF CA versus minimal (< 2min) fluoroscopy across multiple institutions.
Methods: Prospective registry study of 162 patients enrolled between March 2016 and March 2018 for CA of symptomatic, drug-refractory paroxysmal or persistent AF at 5 centers proficient in high-volume, minimal fluoroscopy CA. We evaluated procedural details, acute procedural outcomes and complications and one-year follow-up data. All operators used an EAM system (Carto, Biosense Webster) and ICE.
Results: 160 patients were analyzed. 100 (63%) procedures were performed with zero fluoroscopy. Mean procedure duration between two groups did not significantly differ 192 ±37 min vs 201 ± 29min, p0.96. Pulmonary vein isolation was achieved in 153/153 patients (100%) with overall acute procedural complication rate of 1.8% and did not significantly differ between both groups. One-year follow-up data was available for 152 (93%) patients and mean follow time was 11.3±1.8 months. Freedom from atrial arrhythmia was similar between zero and minimal fluoroscopy groups (75% vs 77% , p0.5) and low late complication rate.
Conclusion: This is the first multi-center, prospective evaluation of both procedural and clinical outcomes for minimal and zero fluoroscopic CA for AF. Minimal and zero fluoroscopy ablation was found to be safe and effective.
