Total Anomalous Pulmonary Venous Connection- Overview

Total anomalous pulmonary venous connection (TAPVC) is a condition in which, with or without pulmonary venous blockage, all four pulmonary veins drain into systemic veins or the right atrium. In the right atrium, systemic and pulmonary venous blood are mixed. In both foetal and newborn circulation,...

• Total Anomalous Pulmonary Venous Connection (TAPVC) is a congenital heart defect where pulmonary veins fail to connect to the left atrium, instead draining into the right atrium or systemic veins. An atrial septal defect (ASD) or patent foramen ovale (PFO) is essential for survival, providing a right-to-left shunt. Drainage can occur into the right atrium, superior vena cava (SVC), coronary sinus, or portal vein.
