Successful treatment of anomalous origin of the left coronary artery from the pulmonary artery in a 5-week-old male infant.

A 5-week-old male infant who was referred to our hospital because of tachypnea and poor feeding. An electrocardiogram showed a deep Q wave in lead aVL, negative T waves in leads I, II, III, aVF and V6 and a positive T wave in VL. Echocardiography revealed severely impaired left ventricular function. Aortography confirmed with a diagnosis of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA). Takeuchi's procedure was performed and the patient maintained postoperatively on assisted circulation for 7 hours even though sternal closure delayed until 7 days post operatively. His left ventricular function showed and marked improvement gradually.
