Total anomalous pulmonary venous return (TAPVR) is a rare congenital heart malformation that accounts for 1% to 3% of all congenital heart anomalies [1].

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 causes 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.

What is Tapvc in cardiology?

Total anomalous pulmonary venous return (TAPVR) (pronounced TOHT-l uh-NOM-uh-luh-s PUHL-muh-ner-ee VEE-nuh-s ri-TURN), or connection (TAPVC) is a birth defect of the heart in which the veins bringing blood back from the lungs pulmonary veins) don’t connect to the left atrium like usual.

Is Tapvc genetic?

Total anomalous pulmonary venous return (TAPVR) is a congenital heart defect inherited via complex genetic and/or environmental factors.

Is Tapvc curable?

To repair this defect, doctors usually connect the pulmonary veins to the left atrium, close off any abnormal connections between blood vessels, and close the atrial septal defect. Infants whose defects are surgically repaired are not cured; they may have lifelong complications.

What is TAPVR surgery?

Total anomalous pulmonary venous return (TAPVR) is a condition in which the blood vessels from the lungs take an abnormal path back to the heart. TAPVR surgery is open heart surgery done to fix this problem. The heart has 4 chambers: a right and left atrium and a right and left ventricle.

Is Tapvc a congenital heart defect?

Because a baby with this defect may need surgery or other procedures soon after birth, TAPVR is considered a critical congenital heart defect. Congenital means present at birth.

Why is TAPVR cyanotic?

Symptoms. A baby with TAPVR may have breathing difficulty and appear blue (cyanotic) because of the lack of oxygen in the blood that goes out to the body, or because blood flow through the pulmonary veins is reduced or blocked. A doctor may notice signs and symptoms of TAPVR soon after birth.

Is TAPVC normal?

Total anomalous pulmonary venous return (TAPVR) is a rare congenital malformation in which 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) by way of an abnormal (anomalous) connection.

How common is TAPVC?

PAPVC is a rare congenital heart disease, with a prevalence of 0.1-0.2% in adult population reported by a recent study [1].

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 total anomalous pulmonary venous return (TAPVR)?

Total anomalous pulmonary venous return (TAPVR) is a birth defect of the heart. In a baby with TAPVR, oxygen-rich blood does not return from the lungs to the left atrium.

What is TAPVR and how does it affect the baby?

This causes the baby to get less oxygen than is needed to the body. To survive with this defect, babies with TAPVR usually have a hole between the right atrium and the left atrium (an atrial septal defect) that allows the mixed blood to get to the left side of the heart and pumped out to the rest of the body.

What does TAPVC stand for in medical terms?

Total Anomalous Pulmonary Venous Connection (TAPVC) 1 A defect in the veins leading from the lungs to the heart. 2 Information for Parents of children with TAPVC. 3 Adults with TAPVC. What causes it? In most cases, the cause isn’t known.
