Corpus: Great cardiac vein

The Vena cardiaca magna is a cardiac vein that opens into the coronary sinus.

The great cardiac vein begins at the apex cordis and runs anteriorly in the interventricular sulcus to the base of the cardiac ventricles. The section running in the sulcus is known as the anterior interventricular vein. The great cardiac vein then bends onto the posterior surface of the heart and joins with the oblique sinus vein to form the coronary sinus. Shortly before this, it picks up the marginal sinus vein.

The vena ventriculi sinistri posterior, the vena cardiaca media and the vena cardiaca parva can flow into the vena cardiaca magna or directly into the coronary sinus.

The great cardiac vein receives venous blood from the anterior wall of both ventricles and from the lateral wall of the left ventricle.
