3. • Fig CA 2-1 Tetralogy of Fallot. (A) Frontal view
shows right ventricular enlargement as a
lateral and upward displacement of the
radiographic cardiac apex (arrow). (B) On the
lateral view, the enlarged right ventricle fills
most of the retrosternal space (arrows).

4. • Fig CA 2-2 Pulmonary stenosis. (A) Frontal and
(B) lateral views show striking poststenotic
dilatation of the pulmonary artery (arrow) in
addition to filling of the retrosternal air space,
indicating right ventricular enlargement.

5. • Fig CA 2-3 Mitral stenosis. (A) Frontal and (B)
lateral views of the chest demonstrate
cardiomegaly with enlargement of the right
ventricle and left atrium. The right ventricular
enlargement causes obliteration of the
retrosternal air space, whereas left atrial
enlargement produces a convexity of the upper
left border of the heart (arrow, A).

6. • Fig CA 2-4 Cor pulmonale. (A) Frontal and (B)
lateral views of the chest in a patient with
primary pulmonary hypertension show marked
globular cardiomegaly with prominence of the
pulmonary trunk and central pulmonary arteries.
The peripheral pulmonary vascularity is strikingly
reduced. Right ventricular enlargement has
obliterated the retrosternal air space on the
lateral view.
