Summary
A 9-month-old male baby was investigated for a massive left-to-right shunt at the
arterial level. On right heart catheterization a patient ductus could not be demonstrated
but retrograde arterial angiography showed an aorto-pulmonary window.
During corrective surgery on cardiac bypass, the left coronary artery was found to
arise from the aorto-pulmonary window, this was corrected by dividing the communication
distal to the origin of the left coronary artery. On follow-up investigation 6 months
after operation the baby was without symptoms and showed a fully functional left coronary
artery. To our knowledge this is the first case of such a congenital anomaly to be
described,
Key words
Aorto-pulmonary window - Anomalous origin of left coronary artery
