Novel ablation strategy improves freedom from arrhythmias in atrial fibrillation patients

An innovative three-step ablation approach including ethanol infusion of the vein of Marshall improves freedom from arrhythmias in patients with persistent atrial fibrillation compared to pulmonary vein isolation (PVI) alone, according to late breaking science presented at EHRA 2023. Preliminary results at 10 months are presented, with follow up ongoing until 12 months.
