- 9. Developmental anatomy ofthe coronary sinus (CS) (26 weeks)—the right horn of the sinus venosus remains as the venous portion of the right atrium between the vena cava (light blue). H
- 10. The CS hasbeen dissected open along its long axis, CS musculature is seen in the proximal portion of the CS up to the orifice of the vein of Marshall. In this patient multiple posterior and posterolateral veins are also seen draining into the CS.

Transesophagealechocardiography revealed both atrial and right ventricular enlargement (left), a defect of the partial coronary sinus (middle), and shunt of the left atrium to the dilated coronary sinus (right) at the near longitudinal plane.
