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

JRCT ID: jRCT1052210026

Registered date:17/05/2021

Basic Information

• Recruitment status: Not Recruiting
• Health condition(s) or Problem(s) studied: Atrial fibrillation
• Date of first enrollment: 22/06/2021
• Target sample size: 80
• Study type: Interventional
• 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.

Outcome(s)

• Primary Outcome: Atrial arrhythmia recurrence beyond 90 days after catheter ablation for atrial fibrillation

Secondary Outcome

Atrial 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
