Complete obstruction of the left main coronary artery associated with congenital pulmonary valvular stenosis.

The major diagnostic challenge was in differentiating primary cardiopulmonary disease from a central abnormality of ventilatory drive. The arterial blood gases showed a normal A-a gradient suggesting hypoventilation as the etiolog...
