A rare case of mixed type total anomalous pulmonary venous connection and its surgical treatment

Abstract

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 intracardiac 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.
