We present the case of a 4-month-old female who had complex supracardiac total anomalous pulmonary venous connection, diagnosed by catheterization. Her right pulmonary veins drained into the left brachiocephalic vein and then into the superior vena cava. The left pulmonary veins drained into the hemiazygous and azygous veins and eventually into the superior vena cava. She had no other major structural abnormalities except for a secundum-type atrial septal defect and patent ductus arteriosus. Although several rare mixed types of total pulmonary venous connection have been reported in the literature, to our knowledge, the anomaly our patient had has not been described previously.
