What is Anomalous Pulmonary Venous Return?

Also known as: total anomalous pulmonary venous return, TAPVR, partial anomalous pulmonary venous return, PAPVR

In a normal heart, there are four veins that return blood with oxygen from the lungs to the heart's left upper chamber (the left atrium). Two from the left lung and two from the right lung. When one or more of these veins are attached to the wrong part of the heart or another blood vessel, it's known as anomalous pulmonary venous return.
