Objective To assess the effectiveness and safety of remote magnetic navigation for mapping and ablating supraventricular arrhythmia. Methods Different types of supraventricular arrhythmia patients underwent remote control mapping and ablation using the NiobeⅡmagnetic navigation system. Five patients 3 males and 2 females,mean age (45±18) years were included. Two patients had history of structural heart diseases. Cavotricuspid isthmus-dependent right atrial flutter was found in 2 patients,and 1 combined with atrioventricular nodal reentrant tachycardia. Left free wall accessory pathway was found in 2 patients,and right posterior septal accessory pathway in 1 patient. Results Based on standard electrophysiological investigation,all 5 patients were submitted to procedure with remote control manipulation for mapping and ablating supreventricular arrhythmia. The procedure was successful in 4 patients. The average procedure time was (116±31)min. Fluoroscopy time of operator was (4.5±1.5)min. No complication was observed in all 5 patients. Conclusion Remote control mapping and ablation of supraventricular tachyarrhythmia is safe and feasible using magnetic navigation technique. This technique can also decrease the fluoroscopy time of operator.
