| Middle cardiac vein | |
| Latin: | vena cardiaca media, vena cordis media |
| Drainsto: | Coronary sinus |
| Artery: | Posterior interventricular artery |
The middle cardiac vein commences at the apex of the heart. It passes posteriorly along the inferior interventricular sulcus to end at the coronary sinus near the sinus' termination.[1]
The middle cardiac vein commences at the cardiac apex (here, it is contiguous with the great cardiac vein, thus forming - along with the coronary sinus - a complete venous circle).
The middle cardiac vein has a constant location on the surface of the ventricles.
The middle cardiac vein is useful for epicardial access to the inferior side of the ventricles.
