were present. His blood pressure was 100/70 mm Hg, and the pulse regular at 100/minute. The heart showed a hyperdynamic right ventricular impulse. A Grade II/VI systolic murmur was heard in the second and third intercostal spaces at the left sternal edge. The second heart sound was loud at the pulmonic area. The ECG showed right ventricular hypertrophy. On the chest x-rays, the heart appeared slightly enlarged and an increase in pulmonary vascular markings could be noted. Cardiac catheterization data is given in Table I. The cineangiograms (Fig. 1) established the diagnosis of simple transposition of the great arteries.
