The left marginal vein originates on the left ventricle.


It courses with the left marginal artery as it travels superiorly along the left cardiac border. It drains into the great cardiac vein or the coronary sinus (Standring, 2016, Tubbs et al., 2016).


The left marginal vein is formed by the union of small unnamed veins.

Structures Drained
