Surgical therapy of a coronary artery fistula draining into the left atrium.

Coronary artery fistulas (CAFs) are rare vascular anomalies. We describe a case of CAF draining into the left atrium, combined with an atrial septum defect (ASD) and azygos continuity in a 3-year-old girl. Surgical therapy included closure of the ASD combined with closure of the CAF through a left atrial approach. Even though CAF can be treated by interventional means, surgical correction may be required in the presence of associated cardiac abnormalities.
