Catheter ablation has become a cornerstone treatment for atrial fibrillation (AF). Pulmonary vein isolation is the accepted approach for paroxysmal AF ablation, but it is less effective for persistent AF. The vein of Marshall (VOM) is located in the epicardial left atrium and can be a source of AF triggers as well as a tract for autonomic nerves. It directly communicates with the underlying myocardium, including the left atrial ridge and the posterior mitral isthmus. This review discusses the latest evidence regarding the mechanisms, procedural aspects, and outcomes of VOM ethanol infusion when used as an adjunct to pulmonary vein isolation in patients with persistent AF.

Surface Electrocardiogram

Atrial tachycardia (AT) is increasingly observed in patients, particularly in the context of atrial fibrillation ablation. The exact electrophysiological mechanisms are not easy to establish but a practical approach consists in distinguishing macroreentries from focal ATs as this is crucial for the ablation strategy. In centrifugal arrhythmias (such as focal AT and localized reentry), the activation originates from a source and spreads centrifugally to the rest of the atria, while in macroreentries, it follows a large path around a central obstacle and reenters. The analysis of the surface electrocardiogram is of limited value to predict the macroreentrant or focal nature of the arrhythmia. Antiarrhythmic drugs are usually tried first and in case of failure, catheter ablation is considered, with or without the support of a localization/mapping system. The most challenging cases are those with multifocal AT as they are poorly responsive to drugs, difficult to ablate, and arise in patients in poor medical conditions. New technologies such as high-density mapping and non-invasive mapping may facilitate the identification of mechanisms and target(s) for catheter ablation.
