ALCAPA with normal left coronary artery flow pattern and demonstration of flow reversal on oxygen inhalation

Anomalous left coronary artery from pulmonary artery (ALCAPA) is an uncommon congenital heart defect. In most of the cases it presents in early infancy when the pulmonary artery pressure decreases and pulmonary vascular resistance falls. ECG and chest X-ray help in diagnosing this condition, however, transthoracic echocardiography confirms the diagnosis in most of the cases. 2D echo shows origin of left coronary artery from pulmonary artery and on colour Doppler retrograde flow is seen in left main, left anterior descending and left circumflex coronary arteries.
