Coronary fistula associated with severe pulmonary stenosis and cianosis

A 17 year old male adolescent was admitted to the hospital due to dyspnea and cyanosis, since the age of 6 years. On physical examination, it was found a continuous murmur over the left esternal border at the 4th and 5th intercostal spaces suggesting a coronary fistula. A color-echocardiogram associated with an angiography confirmed the diagnosis of coronary fistula and severe pulmonary stenosis. The functional consequence was a right to left shunt with cyanosis. A surgical repair was performed with closure of the fistula at the point where it drained into the right ventricle plus a pulmonary commissurotomy. The patient had an uneventful recovery.
