The structure indicated is the small cardiac vein
The coronary sinus
lies posteriorly on the heart in the coronary sulcus
and receives four cardiac veins
- Great cardiac vein
- Middle cardiac vein
- Small cardiac vein
- Posterior cardiac veins
The coronary sinus returns deoxygenated
blood to the right atrium of the heart, together with the superior and inferior vena cavae
. The small cardiac vein lies in the coronary sulcus between the right atrium and the right ventricle.
