In the mixed types of total anomalous pulmonary venous connection, pulmonary veins
frequently show an opening at the supracardiac and cardiac level. Rarely, some other
combinations of mixed type cases have been reported in the literature. In the present
case the right and left pulmonary veins formed two distinct venous chambers and showed
supracardiac and infracardiac openings. Anastomosis of each of these common venous
chambers was performed to the left atrium, separate from each other, by extracardiac
approach. The patient had no hemodynamic problems in the postoperative period and
showed no pulmonary venous obstruction in a control angiography performed after 9
months. He has not needed medication and has shown no limitation of activity during
a follow-up of 6 years.
