Study summary

This is an open label, multi-center, randomized parallel control clinical trial, to demonstrate the role of driver mechanism in maintenance substrate of persistent atrial fibrillation, and evaluate the clinical outcomes of driver mapping and ablation strategy in patients with persistent atrial fibrillation.

Read the detailed description

This is an open label, multi-center, randomized parallel control clinical trial. Patients with persistent atrial fibrillation are 1:1 randomized into the experimental group (driver ablation+ circumferential pulmonary vein isolation) or the control group (stepwise ablation). Postoperative atrial fibrillation recurrence rate and other indicators are analyzed to demonstrate the role of driver mechanism in maintenance substrate of persistent atrial fibrillation and evaluate the clinical outcomes of driver mapping and ablation strategy in patients with persistent atrial fibrillation.

What researchers measure

Primary outcomes

  1. Postoperative atrial fibrillation (AF) recurrence rate

    AF recurrence is defined as presence of documented AF episodes of 30 seconds or longer duration.

    Time frame: up to 24 months after enrollment

  2. Procedural AF termination rate

    AF termination is defined as conversion to sinus rhythm or a stable atrial flutter (AFL)/atrial tachycardia (AT).

    Time frame: Before the end of procedure.

Secondary outcomes

  1. Postoperative atrial flutter (AFL) or atrial tachycardia (AT) rate

    Occurrence of AFL/AT is defined as presence of documented AFL/AT episodes of 30 seconds or longer duration.

    Time frame: up to 24 months after enrollment

  2. Incidence of complications

    Complications include: death, atrioesophageal fistula, cardiac tamponade/perforation, myocardial infarction, stroke/cerebrovascular accident, thromboembolism, transient ischemic attack (TIA), diaphragmatic paralysis, pneumothorax, heart block, pulmonary vein stenosis, pulmonary edema, pericarditis, and major vascular access complication or bleeding.

    Time frame: up to 2 weeks after enrollment
