3. Fig CA 6-1 Tetralogy of Fallot . Plain chest radiograph demonstrates decreased pulmonary vascularity and a flat pulmonary outflow tract. Note the characteristic lateral displacement and upward tilting of the prominent left cardiac apex ( coeuren sabot appearance).

4. Fig CA 6-2 Pseudotruncus arteriosus. (A) Plain chest radiograph shows the pulmonary vascularity to be strikingly diminished. (B) Angiogram shows that most of the blood supply to the lungs originates from two large arteries arising from the descending aorta. 1

5. Fig CA 6-3 Trilogy of Fallot . Decreased pulmonary vascularity with prominent poststenotic dilatation (arrow) of the pulmonary artery. There is enormous right atrial and moderate right ventricular enlargement. 6

6. Fig CA 6-4 Tricuspid atresia. Decreased pulmonary vascularity with elongation and rounding of the left border of the heart.

7. Fig CA 6-5 Ebstein's anomaly. In addition to decreased pulmonary vascularity, there is enlargement of the right atrium, causing upward and outward bulging of the right border of the heart (squared appearance). Widening of the right side of the superior portion of the mediastinum (arrows) reflects marked dilatation of the superior vena cava due to right ventricular failure.

8. Fig CA 6-6 Pulmonary atresia. Decreased pulmonary vascularity with a concave outflow tract and moderate cardiomegaly.
