Q

The venae cordis minimae

A

They are present in all four heart chambers, but are more common in the right atrium, especially along the interatrial septum.

a number of small veins in the walls of all of the heart chambers. An alternative name is the Thebesian veins. They originate within the myocardium and pass deeply through the endocardium of the nearest chamber. Their orifices into the chambers are termed the foramina venarum minimarum.
They return venous blood and may also pass oxygenated blood to the myocardium.
