PVI using pulsed field ablationvein of Marshall ethanol infusion
What this trial is about
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.
