A- Coronary Sinus
1.It is a wide venous channel situated in the posterior part of coronary sulcus and ends in
the right atrium.

9. Tributaries of Coronary Sinus
1. Great cardiac vein: ascends with the anterior inter-ventricular artery, then curves with the
circumflex artery. Small cardiac vein: accompanies the marginal artery.
2. Middle cardiac vein: accompanies the posterior inter- ventricular artery.
3. Small cardiac vein : accompanies the marginal artery .
4. Oblique vein of left atrium (of Marshal): descends obliquely on the back of the Lt. atrium.
5. Posterior vein of the left ventricle: to the left side of the middle cardiac vein.

Anterior margin:
q Begins at the apex 1 inch above the medial
1/3 of clavicle.
q Descends behind the sterno-clavicular
joint.
q Reaches the sternal angle.
q Then, descends to the 4th costal cartilage.
q The right pleura continues till the 6th costal
cartilage.
q The left pleura arches outwards and
descends lateral to the sternal border
making the cardiac notch, till it reaches the
6th costal cartilage.
Inferior margin:
q From the 6th costal cartilage, each line
turns laterally passing around the chest
wall crossing mid-clavicular line at 8th rib.
q Mid-axillary line at 10th rib.
q Midline posteriorly at 12th thoracic
vertebra.
Posterior margin:
q From the 12th thoracic vertebra upwards
till the apex.

Fissures:
Oblique fissure (in both sides): From the
3rd thoracic spine to the 6th costal cartilage.
Horizontal fissure (only in the right): From
the 4th costal cartilage till it meets the oblique
fissure.
