<p>The coronary blood flow in cases of atresia of the left coronary artery ostium is supplied through collateral vessels from the right coronary artery. Therefore, the severity of symptoms depends on the condition of this vessel. We experienced a seven-year-old girl who complained of chest pain during exercise. We performed myocardial scintigraphy using techenetium-99m-tetrofosmin and observed the rare reverse redistribution phenomenon. We suspected myocardial ischemia. We performed coronary angiography and diagnosed her with atresia of the left coronary artery ostium. As there was no stenosis in the coronary artery in this case, the coronary artery was successfully dilated by adenosine loading, thereby increasing the coronary blood flow and thus the blood flow in the myocardium. Our findings may help prevent cardiac accident.</p>
