The mixed type of total anomalous pulmonary venous connection is the least common variant, occurring in approximately 5% of all patients. Dual drainage through a common venous confluence is much rarer. Computed tomography to delineate the exact pulmonary venous anatomy is a must in such cases. Correct preoperative recognition and intraoperative confirmation to check the drainage of all 4 pulmonary veins is essential in all cases of total anomalous pulmonary venous connection. We report the case of an adult patient with dual drainage to coronary sinus and left vertical vein to innominate vein.
