Abstract
A case of single coronary artery is described in a boy who died at the age of 4 months. He had, since birth, been somewhat reluctant to feed and later on episodes of pallor, cyanosis and dyspnoea occurred. Radiogram showed cardiac enlargement. Electrocardiogram showed deep Q-waves in leads aVL and V2-6 S-T segment depressed in leads I and n, and elevated in V2-6 and negative T-waves in leads I, II and V6. It can be impossible to distinguish between the present anomaly and anomalous origin of left coronary artery from the pulmonary artery. At autopsy absence of the left coronary artery and its ostium was recognized, but apart from this no cardiac malformations were found.
