The Randomized Controlled Trial Evaluating Utility of Catheter Ablation Us ing ExTRa mapping for Atrial Fibrillation

Basic Information

Recruitment status Not Recruiting
Health condition(s) or Problem(s) studiedAtrial fibrillation
Date of first enrollment22/06/2021
Target sample size80
Countries of recruitment
Study typeInterventional
Intervention(s)Atrial sites of high %NP (%NP >35% and LVZ <0.5mV for the first 20 pts., and %NP >35% for the ne xt 20 pts) were ablated, and electr ical car diversio n was performed when sinus resta nd electrical ca rdiversion was performed when sin us restoration was not obtained in 15 minutes afte r injection of Nifekalant 0.3mg/kg.


Primary OutcomeAtrial arrhythmia recurrence beyond 90 days after catheter ablation for atrial fibrillation
Secondary OutcomeAtrial fibrillation termination rate Atrial fibrillation-free survival, atrial tachycardia-free survival Procedure detail (procedure time, ablation number, ablation region) Adverse events Atrial arrhythmia recurrence beyond 90 days after repeat procedures The difference of results compared between the different ExTRa-guide ablatio n in combined data with CONTROL-AF study
