Key result
Transthoracic echocardiography revealed a venous structure protruding within the left atrial cavity in four patients, possibly representing Marshall's vein or a persistent left superior caval vein.
Case Report (n=4)
Transthoracic echocardiography can visualize venous structures in the left atrium that may represent Marshall's vein, a potential arrhythmic substrate.
TTE visualization of left atrial venous structures warrants recognition; leaves open their arrhythmic relevance in larger cohorts.
Thus far, little has been written concerning echocardiographic identification of the oblique vein of the left atrium, or Marshall's vein. There is much discussion, nonetheless, on the potential significance of the vein, or its ligamentous remnant, as an arrhythmic substrate. We describe here four patients in whom transthoracic echocardiography revealed a venous structure protruding within the cavity of the left atrium. We discuss the possibility that these structures represent Marshall's vein, albeit probably as part of a persistent left superior caval vein.
