Outcome Measures

Primary Outcomes (1)

  • Postoperative atrial fibrillation (AF)/atrial flutter (AFL)/atrial tachycardia (AT) recurrence rate

    AF/AFL/AT recurrence is defined as presence of documented AF/AFL/AT episodes of 30 seconds or longer duration

    up to 24 months after enrollment

Secondary Outcomes (2)

  • Postoperative AF recurrence rate

    up to 24 months after enrollment

  • Postoperative AFL/AT rate

    up to 24 months after enrollment

Other Outcomes (3)

  • Changes in the diameter of the left atrium

    up to 24 months after enrollment

  • Changes in the diameter of the left ventricular ejection fraction

    up to 24 months after enrollment

  • Incidence of complications

    up to 24 months after enrollment

Study Arms (2)

CARTO-Finder-guided ablation plus PVI

ACTIVE COMPARATOR

Pulmonary vein circumferential isolation + + ablation of sites recognized by CARTO-Finder module as the core of rotors.

Procedure: CARTO-Finder-guided ablation plus PVI

Multiscale entropy-guided ablation plus PVI

EXPERIMENTAL

Pulmonary vein circumferential isolation + ablation of sites recognized by multiscale entropy analysis as the core of rotors.

Procedure: Multiscale entropy-guided ablation plus PVI

Interventions

The multiscale entropy is calculated based on intracardiac electrical signals, higher multiscale entropy value indicates closer to the core of rotors which maintains the persistent atrial fibrillation.
