Summary

Paroxysmal supraventricular tachycardia is treated with radiofrequency ablation recently. This procedure is performed by ablating slow pathway or accessory pathway using radiofrequency ablation catheter. Recently developed mirofidelity (MIFI) catheter has mini-electrodes that can record local eletrogram with higher resolution. We aimed to investigate the efficacy of MIFI catheter in the ablation of paroxysmal supraventricular tachycardia compared to conventional radiofrequency ablation catheter. Enrolled patients undergo conventional electrophysiologic study. Patients with sustained supraventricular tachycardia during the study are randomized to either study group or control group. Radiofrequency ablation is performed using MIFI catheter in the study group, and conventional catheter (Blazer II) in the control group. The study endpoints are recorded immediately after ablation and there is no additional follow up or management after procedure.

Conditions

• Paroxysmal Supraventricular Tachycardia

Interventions

Type	Name	Description
DEVICE	Microfidelity (MIFI) catheter	Patients are randomized into the MIFI group and control group. Radiofrequency ablation will target slow pathway for AVNRT or accessory pathway for AVRT. Microfidelity (MIFI) catheter equipped with mini-electrodes will be used for ablation in the MIFI group.
DEVICE	Conventional ablation catheter	Patients are randomized into the MIFI group and control group. Radiofrequency ablation will target slow pathway for AVNRT or accessory pathway for AVRT. Blazer II radiofrequency ablation catheter will be used for ablation in the control group.
