Total Anomalous Pulmonary Venous Return (TAPVR) | Symptoms & Causes

What are the symptoms of total anomalous pulmonary venous return?

Most babies born with total anomalous pulmonary venous return (TAPVR) are very ill soon after birth. Symptoms may include:

  • a bluish tint to the skin and lips
  • trouble breathing
  • rapid breathing
  • poor feeding or poor growth

If your child has any of these symptoms, your pediatrician may refer you to a pediatric cardiologist for testing.

What are the causes of total anomalous pulmonary venous return?

In many cases, we don’t know what causes TAPVR. It occurs because of abnormal development of the heart’s pulmonary veins during early fetal growth.

Some congenital heart defects may have a genetic link, causing heart problems to occur more often in certain families. Most often, though, this heart defect occurs by chance, with no clear reason for its development.
