    Efficacy endpoint: Including recurrence of atrial fibrillation, atrial flutter, and atrial tachycardia (sustaining more than 30s)

    3 and 12 months from the date of procedure

Secondary Outcomes (1)

  • Procedural complications

    through study completion, an average of 1 year

Study Arms (2)

VOMEI + PVI + linear ablation of mitral isthmus + PWI

EXPERIMENTAL

Acquisition of left atrial posterior wall isolation by linear ablation of LA roof and bottom line, in addition to routine strategy with vein of Marshall ethanol infusion, isolation of bilateral pulmonary veins and linear ablation of mitral isthmus.

Procedure: VOMEI + PVI + linear ablation of mitral isthmusProcedure: Posterior wall isolation

VOMEI + PVI + linear ablation of mitral isthmus

ACTIVE COMPARATOR

Routine strategy with vein of Marshall ethanol infusion, isolation of bilateral pulmonary veins and linear ablation of mitral isthmus. Left atrial posterior wall not isolated.

Procedure: VOMEI + PVI + linear ablation of mitral isthmus

Interventions

The CS angiography is firstly performed to visualize the vein of Marshall. The ethanol infusion by anhydrous alcohol is then performed by using a guidewire and an OTW ballon. For radiofrequency catheter ablation, the standard procedure of pulmonary vein isolation is performed. All the enrolled persistent AF patients perform the routine linear ablation of mitral isthmus.

PWI is additionally performed for experimental group with linear ablation of LA roof and bottom line, and verified by mapping with a multielectrode catheter.

Masking Details
This study used a single-blind design for the subjects. A statistician created a random sequence of numbers using a randomization scheme. The sequence was then placed in opaque coded envelopes and sealed in numerical order. When a patient met the inclusion and exclusion criteria and was assigned a number, the researcher notified the manager to obtain the corresponding envelope and perform the intervention according to the grouping plan inside the envelope. Group 0 correspond to the control group not receiving PWI isolation, while group 1 correspond to the experimental group for PWI isolation.

Model Details: A total of 260 participants with persistent AF who undergo radiofrequency catheter ablation and received VOMEI + PVI will be randomized assigned to two groups at 1:1 ratio. Group 0 (Control): VOMEI + PVI + linear ablation of mitral isthmus. Group 1 (Experimental): VOMEI + PVI + linear ablation of mitral isthmus + PWI
