Surgery is the mainstay of treatment in total anomalous pulmonary venous connection and should be performed as soon as possible. The surgical procedure varies depending upon the anatomy of the TAPVC lesion.

• Surgery is the mainstay of treatment in total anomalous pulmonary venous connection and should be performed as soon as possible.^[1]

• The surgical procedure varies depending upon the anatomy of the TAPVC lesion.
• Supracardiac and infracardiac TAPVC: connection is created between the pulmonary veins and the left atrium. The vertical vein is tied up so that the abnormal blood flow could be prevented.
• Pulmonary veins directly connected to the superiorvenacava: An intracardiac baffle is created that helps in the transfer of blood from the right atrium, through the atrial septum into the left atrium.
• Intracardiac (pulmonary vein connected to the coronary sinus): Coronary sinus is incised and connected to the left atrium.
• Intracardiac (pulmonary vein opening directly into the right atrium): A interatrial connection is made and the blood is redirected from right atrium to left atrium.
