    A- Coronary Sinus1.It is a wide venous channel situated in the posterior part of coronary sulcus and ends in the right atrium.

  • 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.
