Anomalous pulmonary venous return
Anomalous pulmonary venous return refers to a form of rare cyanotic congenital heart disease characterised by som or all of the pulmonary venous return entering the systemic circulation through embryological connections.
In case of total anomalous pulmonary venous return (TAPVR), the entire pulmonary venous return enters the systemic circulation, while in case of partial anomalous pulmonary venous return (PAPVR), only some of the pulmonary venous return enters the systemic circulation.
