A coronary arteriovenous fistula consists of a communication between a coronary artery and a cardiac chamber, a great artery or the vena cava. It is the most common anomaly that can affect coronary perfusion. Bilateral involvement of coronary fistula, however, constitutes an uncommon subgroup of coronary arteriovenous fistulas. We report a case which shows a rare occurrence of bilateral coronary arteriovenous fistula coexistent with atrial septal defect and pulmonic stenosis.
