Summary

The Marvel-PAF trial is an investigator initiated, multi-center, open-label, randomized trial, which aims to compare the effectiveness of vein of Marshall in addition to pulmonary vein isolation using pulsed field ablation in the treatment of paroxysmal atrial fibrillation. The primary endpoint is any atrial arrhythmias lasting ≥30s without AAD during 12 months after procedure excluding the 2-months blanking period.

Conditions

  • Atrial Fibrillation (AF)

Interventions

PROCEDURE

vein of Marshall ethanol infusion

After PFA, the coronary sinus venography will be acquired in search of VOM ostium. Then an over-the-wire balloon will be sent into the VOM and deflated with 4-6 atm. Selective VOM venography will be performed, followed by injection of 10ml 95% ethanol into the VOM.

PROCEDURE

PVI using pulsed field ablation

Bilateral pulmonary vein antrum ablation using a pulsed field ablation
