The left circumflex coronary artery associated with a fistula to superior vena cava is a rare entity. We describe a 7-year-old girl who presented with a cardiac murmur and was diagnosed with a coronary artery fistula between the left circumflex artery and superior vena cava by echocardiography. The surgical occlusion of the fistula was successful.
Keywords: echocardiography; fistula; left circumflex coronary artery.
