How is TAPVR diagnosed?

TAPVR might be diagnosed during pregnancy with an ultrasound (which creates pictures of the body). Some findings from the ultrasound may make the health care provider suspect a baby could have TAPVR. If so, the health care provider can request a fetal echocardiogram to confirm the diagnosis.

What are the four 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 is Infracardiac TAPVC?

Infracardiac TAPVR is a subtype of TAPVR in which the pulmonary veins connect via the umbilicovitelline system.

What happens in TAPVC?

Normally, oxygen-rich blood goes from the lungs to the upper left heart chamber (left atrium) and then flows through the body. In TAPVR , an abnormal connection of veins sends blood through the upper right heart chamber (right atrium) instead, where it mixes with oxygen-poor blood.

What is the most common type of TAPVR?

There are 4 types of TAPVR with the mixed type being the least common. Any type of TAPVR may be associated with obstruction as result of flow redirection through the liver parenchyma before it may return to the heart, but infracardiac is the most common one.

What causes TAPVR?

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.

Which type of TAPVR is most common?

Is TAPVR single ventricle?

Sometimes it stays open with TAPVR. This causes oxygen-poor and oxygen-rich blood to be mixed. Single ventricle. In this condition, there is only 1 ventricle instead of the normal 2.

Is TAPVC normal?

Total anomalous pulmonary venous return (TAPVR) is a rare congenital (present at birth) defect. With TAPVR, all four pulmonary veins do not connect normally to the left atrium. Instead, the four pulmonary veins drain abnormally to the right atrium (right upper chamber) through an abnormal (anomalous) connection.

What is mixed TAPVC?

Mixed TAPVC (type 4) is a rare condition, accounting for only 5% of diagnosed TAPVC. [2] It is associated with a poor prognosis unless surgically corrected by connecting the pulmonary venous sinus to the left atrium.

How common is TAPVC?

About 1 in every 20,000 babies is born with TAPVR. In order to get blood to the body, most babies with TAPVR also have another heart defect, called atrial septal defect, which is a hole from the right atrium to the left atrium.

What is Snowman heart?

Snowman sign refers to the configuration of the heart and the superior mediastinal borders resembling a snowman. This is seen in total anomalous pulmonary venous return (TAPVR) type I (supracardiac type). It is also referred to as the figure of 8 sign.

Is TAPVR hereditary?

Abstract. Total anomalous pulmonary venous return (TAPVR) is a cyanotic congenital heart defect that, without surgical correction, has a high mortality rate in the first year of life. It usually occurs without a family history and has a low recurrence risk.

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.

Is TAPVR life threatening?

Total anomalous pulmonary venous return (TAPVR) is a rare, life-threatening congenital heart defect that affects newborns. It happens when veins from your baby’s lungs connect to the wrong place in their heart, leading to problems with blood flow. Difficulty breathing and blueish skin usually appear right after birth.

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).

Is TAPVR curable?

Even if your child’s symptoms are not severe right away. Untreated TAPVR often results in death. Surgery is eventually needed in all cases of TAPVR. Some infants need treatment before surgery.
