Efficacy of Remote Magnetic Navigation System Coupled with Remote Magnetic Technology Open Irrigated Catheter in the Treatment for Atrial Fibrillation

Abstract

Introduction: Remote magnetic navigation is designed to reduce procedure time, complications and fluoroscopy time for ablation of atrial fibrillation. This study reports a single center experience of Remote Magnetic Navigation system for radiofrequency ablation atrial fibrillation using an irrigated catheter. Methods: 84 patients were consequently included in the study with symptomatic atrial fibrillation. Anti-arrhythmic drugs and anti-coagulation drugs were stopped one prior to the procedure, when possible. All patients were ablated using Remote Magnetic Navigation Odyssey Stereotaxis system with Remote Magnetic Technology Open Irrigated catheter. Results: Mean patient age was 60.11 years. Mean EF was 49.64%. The mean procedural and fluoroscopy duration was 218.17 ± 37.73 min and 28.04 ± 19.05 min respectively. The learning curve remained flat throughout the cohort. There were four access site hematomas, one need for intubation, and one CVA with full recovery. The successful elimination of AF at 6 months was 86.36%.Conclusion: Radiofrequency ablation coupled with Remote Magnetic Navigation system using an irrigated tip catheter is safe and highly acutely effective. Patient radiation exposure is low. Long term follow up is being tracked.
