Figure 5. Coronary venous anatomy assessed with multislice CT. These 3-dimensional volume-rendered reconstructions clearly show cardiac venous anatomy. (A) The anterior view shows the anterior interventricular vein [AIV] and a left marginal vein [LMV], both draining into the great cardiac vein [GCV]. (B) The more posterior view shows the posterior vein of the left ventricle [PVLV], which drains the posterolateral wall of the left ventricle. Both the PVLV and the posterior interventricular vein [PIV] drain into the coronary sinus [CS], which eventually drains into the right atrium [RA].
