Atrial switch operation in a patient with dextrocardia, bilateral superior vena cavae, left atrial isomerism and unroofed coronary sinus.

The present report describes the technical aspects of the atrial switch operation in the setting of dextrocardia, bilateral superior vena cavae, left atrial isomerism, and unroofed coronary sinus. Augmentation of the right atrial wall using bovine pericardium and in situ pericardial technique for construction of the pulmonary venous baffle ensured unobstructed systemic and pulmonary venous pathways.
