What do we know about this structure?

1) In 1850, a https://abs.twimg.com/emoji/v2/... draggable="false" alt="🇬🇧" title="Flagge des Vereinigten Königreiches" aria-label="Emoji: Flagge des Vereinigten Königreiches"> surgeon described a pericardial fold containing fibrous bands,https://abs.twimg.com/emoji/v2/... draggable="false" alt="🩸" title="Tropfen Blut" aria-label="Emoji: Tropfen Blut">vessels & nerves that courses between LAA & PVs (ligament of Marshall; LOM)

2) The vein of Marshall (VOM), an embryological remnant of the left superior vena cava, runs in the LOM & drains into the coronary sinus

3) An arrhythmogenic role of the VOM has been confirmed in several studies https://doi.org/10.1016/S0735-1097(00)00819-6">https://doi.org/10.1016/S...

4) Recent studies have suggested that catheter-based Ethanol ablation of the VOM may improve the outcomes of PV ablation for AF. https://jamanetwork.com/journals/jama/fullarticle/2772281
