Coronary fistulas are rare congenital anomalies defined by an abnormal communication between a coronary artery and a cardiac chamber or great vessel. We report the case of a 5-year-old male patient (17 kg) referred for cardiac catheterization due to echocardiographic suspicion of patent ductus arteriosus. Coronary angiography revealed a fistula originating from the right coronary artery with direct drainage into the right atrium. Percutaneous closure was successfully performed using a COMED PDA 4/6 device. Post-procedural angiography showed complete occlusion without residual shunt. This case highlights the diagnostic and therapeutic role of cardiac catheterization in congenital coronary anomalies.
