Total Anomalous Pulmonary Venous Return (TAPVR) is a rare congenital malformation in which all four pulmonary veins do not connect normally to the left atrium, but instead drain abnormally to the right atrium by way of an abnormal (anomalous) connection. In type 4, TAPVR, the right and left pulmonary arteries drain into different sites.
