Highlights the clinical importance of the Vein of Marshall in atrial fibrillation ablation, advocating for its increased emphasis in anatomical education.
The oblique vein of the left atrium (Vein of Marshall) is frequently underemphasized in anatomical education and classical texts, often regarded as a minor or vestigial structure. However, contemporary electrophysiological practice has revealed its significant role in the pathophysiology and ablation of atrial fibrillation, particularly through ethanol infusion techniques. This letter highlights the discrepancy between traditional anatomical descriptions and the vein’s emerging clinical importance, emphasizing the need for a more integrated anatomical perspective that reflects modern interventional and electrophysiological advances.
