Healthcare providers aren’t sure what causes TAPVR. It happens when your baby's heart and blood vessels are forming in the womb (uterus) during fetal development. Cardiologists can sometimes diagnose this condition in the prenatal period with a prenatal echocardiogram, which is very helpful to planning.
What is TAPVR heart defect?
Total anomalous pulmonary venous return (TAPVR) is a rare heart defect that's present at birth (congenital heart defect). It is sometimes called total anomalous pulmonary venous connection (TAPVC). In this heart defect, the lung blood vessels (pulmonary veins) are attached to the wrong place in the heart.
What is TAPVR and how does it work?
In TAPVR, the right atrium receives both “blue” blood from the body and “red” blood from the lungs. As a result, the right side of the heart is overworked from pumping the extra blood it receives. Frequently, there is blockage to the veins that receive blood from the pulmonary veins, which causes a backup of blood in the lungs.
What causes TAPVR in babies?
The causes of heart defects, such as TAPVR, among most babies are unknown. Some babies have heart defects because of changes in their genes or chromosomes.
What are the symptoms of TAPVR?
The severity of TAPVR symptoms varies. In some cases, newborns with TAPVR have difficulty breathing and quickly become very ill. This occurs when the pulmonary veins are too narrow or are obstructed at some point, and blood can’t flow from the lungs as quickly as it should. This is called TAPVR with pulmonary obstruction.
How do you prevent TAPVR?
There is no known way to prevent TAPVR.
Can TAPVR be detected before birth?
This test can show problems with the structure of the heart and how well the heart is working. However, TAPVR defect is not commonly detected during pregnancy. It is hard for doctors to see the pulmonary veins on the prenatal screening tests since not much blood goes to the lungs before the baby is born.
How many babies are born with TAPVR?
About 1 out of every 10,000 babies is born with TAPVR. The cause of TAPVR is unknown in most babies. There may be many factors that causes TAPVR, but more research is needed to understand the exact cause for it. TAPVR can be diagnosed during pregnancy or after.
Can you live with TAPVR?
Key points about TAPVR Your child can't live with TAPVR long-term because people need oxygen-rich blood all over their body. All children with TAPVR will need surgery. This is done to restore normal blood flow through the heart. Many children with TAPVR will grow and develop normally after they have surgery.
How long is surgery for TAPVR?
All patients who had obstructive TAPVR required emergency surgery. The mean CPB time was 101.8 minutes (range, 38 to 281 minutes) and the mean aortic cross-clamping (ACC) time was 64.5 minutes (range, 24 to 152 minutes).
How common is TAPVC?
Total anomalous pulmonary venous connection (TAPVC) is a rare developmental cardiac anomaly representing 1%–2%. The pulmonary veins drain the oxygenated blood into the right atrium either directly or indirectly through systemic veins.
What are the 3 different types of TAPVR?
Generally, there are four types of TAPVR:Supracardiac TAPVR. The pulmonary veins drain into the right atrium through the superior vena cava. ... Infracardiac TAPVR. The pulmonary veins drain into the right atrium through the liver (hepatic) veins and the inferior vena cava. ... Cardiac TAPVR. There are two types. ... Mixed TAPVR.
What happens in TAPVC?
In total anomalous pulmonary venous return (TAPVR), the pulmonary veins incorrectly send blood to the heart's upper right chamber (atrium). In a normal heart (shown on the left), oxygen-rich blood flows from the pulmonary veins to the upper left chamber (left atrium).

Is partial anomalous pulmonary venous return hereditary?
Partial anomalous pulmonary venous connection (PAPVC) is a congenital cardiac defect with no known cause and possibly has a multifactorial origin, including a genetic component.
How is Papvr diagnosed?
Echocardiography is the most frequently used method for an initial diagnosis of PAPVR. Increasingly, cardiac magnetic resonance imaging is being used for further delineation of the abnormalities, particularly if surgical intervention is being considered.

What is patent ductus arteriosus?
Open patent ductus arteriosus. The ductus arteriosus is a blood vessel that carries blood away from the heart in a developing baby. It usually closes soon after birth. If it stays open, it's called patent ductus arteriosus. Sometimes it stays open with TAPVR. This causes oxygen-poor and oxygen-rich blood to be mixed. Since ventricle.
What does it mean when a child has a tapvr?
Instead, they're connected somewhere else. There are different types of TAPVR. The type your child has depends on where the pulmonary veins are connected. This condition causes oxygen-rich blood from the lungs to mix with oxygen-poor (blue) blood from the body. This keeps oxygen-rich blood from being carried throughout the body.

How is tapv done?
The surgery is done through a cut (incision) through the breastbone (sternum) and into the chest. Your baby will be connected to a heart-lung machine during surgery. This device does the work of your baby's heart and lungs during surgery. The details of the surgery depend on the type of TAPVR your baby has.
Where does a tapvr end?
To understand the surgery, one important thing to know about TAPVR is that the pulmonary veins, despite their abnormal connections to other veins, all end in a collection (called a “confluence”) at the back of the left atrium. The surgeon opens the confluence so that the veins can drain into the left atrium.
Which veins drain into the right atrium?
The pulmonary veins drain into the right atrium through the liver (hepatic) veins and the inferior vena cava. The inferior vena cava is another large vein that normally carries only deoxygenated blood into the right atrium from the lower half of the body.

What Is Total Anomalous Pulmonary Venous Return
Types of TAPVR
- There are different types of TAPVR, based on where the pulmonary veins connect: 1. Supracardiac– In supracardiac TAPVR, the pulmonary veins come together and form an abnormal connection above the heart to the superior vena cava, which is a main blood vessel that brings oxygen-poor blood from the upper part of the body to the heart. In this type of TAPVR, a mixtur…
Occurrence
- In a 2019 study using data from birth defects tracking systems across the United States, researchers estimated that each year about 504 babies in the United States are born with Total Anomalous Pulmonary Venous Return. In other words, about 1 in every 7,809 babies born in the United States each year are born with Total Anomalous Pulmonary Venous Return.1
Diagnosis
- TAPVR and PAPVR might be diagnosed during pregnancy, but more often these defects are diagnosed soon after a baby is born.
Treatment
- Babies with TAPVR will need surgery to repair the defect. The age at which the surgery is done depends on how sick the child is and the specific structure of the abnormal connections between the pulmonary veins and the right atrium. The goal of the surgical repair of TAPVR is to restore normal blood flow through the heart. To repair this defect, doctors usually connect the pulmonar…
