Total Anomalous Pulmonary Venous Return

Total anomalous pulmonary venous return (TAPVR) is a condition where the pulmonary veins will connect to the right atrium, instead of the left atrium. As such, there is an obligatory right to left shunting. The pulmonary venous return may become obstructed in the post-natal life, which is a neonatal emergency. TAPVR has variants, depending on where the pulmonary veins are draining into. Read more on TAPVR here.
