Left superior vena cava or left vertical vein in supracardiac total anomalous pulmonary venous drainage - Does it make a difference?

Abstract

What do we call a vascular structure that is in the left pneumopericardial space, drains systemic venous blood, and the total pulmonary venous return, into the right atrium, through a dilated coronary sinus (CS)? Can we preserve the CS drainage while correcting the total anomalous pulmonary venous connection?
