Anomalous left coronary artery arising from the pulmonary artery

AbstractA 13-year-old boy was found unconscious. Ventricular fibrillation was seen in his admission to the emergency room. Dilated right coronary artery and increased coronary arterial flow were seen in echocardiography. In the angiography, left coronary artery abnormally arising from pulmonary artery and aneursymatic dilatation in the right coronary artery was seen.<Learning objective: Anomalous left coronary artery arising from pulmonary artery is one of the rare reasons for myocardial ischemia in childhood. Life expectancy can be normal which depends largely on the number of collaterals that are present between right and left coronary arteries. However, sudden death risk always exists.
