"Strategy after Vein of Marshall Ethanol Infusion added to catheter ablation of persistent atrial fibrillation: please, follow the line"

Catheter ablation is an established treatment strategy for patients with drug-refractory atrial fibrillation (AF). However, the success rates in patients with persistent AF remain modest. Current ablation strategies for treatment of persistent AF can be broadly categorized into tailored approaches, aimed at eliminating sources of AF maintenance, and anatomic approaches in which the left atrium (LA) is electrically partitioned by predefined linear lesion sets. Although effective at terminating AF in the acute setting, tailored approaches have been associated with a high risk of subsequent organized atrial tachycardias (ATs) and impairment of atrial function 1.
