Total Anomalous Pulmonary Venous Return (TAPVR) is a congenital defect in which 4 pulmonary veins do not connect normally to the left atrium. Normally, the pulmonary veins return oxygen-rich blood to the left atrium. In TAPVR, the heart cannot make oxygen-rich blood and instead pumps low-oxygen blood throughout the body.   

A baby with TAPVR may also have other heart conditions, such as atrial septal defect (ASD) or patent ductus arteriosus (PDA).

Our fetal heart team diagnoses TAPVR and other congenital heart conditions and provides support to you and your baby during your pregnancy.
