Total anomalous pulmonary venous connection (TAPVC)

Abstract

Total anomalous pulmonary venous connection (TAPVC) is a congenital abnormality in which all pulmonary veins drain into the right atrium, although by varied route. Consequently in the TAPVC, the systemic and pulmonary venous blood drain and will be mixed in the right atrium. An atrial defect or foramen ovale (part of the complex) is important in left ventricular output both in the fetal and in newborn circulation [1, 2].
