Anatomical terminology[edit on Wikidata]

The fold of the left vena cava, ligament of the left vena cava, or vestigial fold of Marshall, is a triangular fold of the serous pericardium that lies between the left pulmonary artery and subjacent pulmonary vein.

It is formed by the folding of the serous layer over the remnant of the lower part of the left superior vena cava (duct of Cuvier), which becomes obliterated during fetal life, and remains as a fibrous band stretching from the highest left intercostal vein to the left atrium, where it is continuous with a small cardiac vein, the vein of the left atrium (oblique vein of Marshall), which opens into the coronary sinus.

Chambers

Right heart	(venae cavae, coronary sinus) → right atrium (atrial appendage, fossa ovalis, limbus of fossa ovalis, crista terminalis, valve of inferior vena cava, valve of coronary sinus) → tricuspid valve → right ventricle (infundibulum, moderator band/septomarginal trabecula, crista supraventricularis), → pulmonary valve → (pulmonary artery and pulmonary circulation)
Left heart	(pulmonary veins) → left atrium (atrial appendage) → mitral valve → left ventricle → aortic valve (aortic sinus) → (aorta and systemic circulation)
