Abstract

Object: Evaluation of results of fluoroless radio frequency catheter ablation (CA) using the three-dimensions (3D) electroanatomic mapping (EAM) system for ventricular arrhythmias (VAs) originating from right ventricular outflow tract (RVOT). Methods: We conducted an observational, prospective study including 126 patients with RVOT VAs who were done CA at E hospital from March 2020 to October 2022. The patients were assigned to 2 different groups of either 3D EAM-used (fluoroless) or fluoroscopy-used group in a 1:1 ratio. Results: The 3D EAM-used group: Acute success rate was 98.4%, longterm success rate was 87.3%, minor and major complication rate was 4.8% (transient right bundle branch block and aneurysm), and 0.0%, respectively. Median radiation time was 0 second. The flouroscopy-used group: Acute success rate was 98.4%, longterm success rate was 84.1%, minor and major complication rate was 4.8% (transient right bundle branch block), and 0.0%, respectively. Median radiation time was 514 seconds. There were no significant difference between two groups in acute success rate, longterm success rate and complication rate with p value > 0.05. Conclusion: Flouroless radio frequency catheter ablation for RVOT VAs can be done safely and effectively by using the 3D electroanatomic mapping system. The results of fluoroless approach are comparable to that of the conventional fluoroscopy approach.
