What are the four types of TAPVR?
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 obstructed TAPVR?
TAPVR can occur with obstruction, meaning that some of the draining blood vessels are obstructed. This can cause high blood pressure in the lungs (pulmonary hypertension) and can be a surgical emergency. Children with TAPVR will need surgery in infancy to repair the problem.
What is TAPVR congenital heart disease?
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. Instead, the oxygen-rich blood returns to the right side of the heart. Here, oxygen-rich blood mixes with oxygen-poor blood.
What is Infracardiac Tapvc?
In total anomalous pulmonary venous connection (TAPVC), the pulmonary veins do not connect directly to the left atrium. Instead, the pulmonary veins drain above the heart (supracardiac), below the heart (infracardiac), or to the coronary sinus or right atrium (cardiac).
How do you treat Tapvr?
How is TAPVR treated?
- Supplemental oxygen or a machine that helps your baby breathe (ventilator).
- Prostaglandin therapy. This medicine keeps the ductus arteriosus open and lets blood flow through the heart.
- Different medicine to support the function of the heart.
- ECMO (extracorporeal membrane oxygenation).
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.
What is the surgery for TAPVR?
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.
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.
How are TAPVR and Supracardiac blood vessels different?
There are different types of TAPVR, based on where the pulmonary veins connect: 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.
What are the four types of infracardiac TAPVR?
There are four main types: supracardiac, intracardiac, infracardiac or mixed venous drainage. Infracardiac TAPVR is a subtype of TAPVR in which the pulmonary veins connect via the umbilicovitelline system.
How does TAPVR affect the right side of the heart?
Another problem that occurs with TAPVR is that too much blood flows through the blood vessels in the lungs, since the pulmonary veins add extra blood back in to the circulation on the right side of the heart. The lungs become stressed by this extra blood flow and can eventually become damaged from it.
When to see a pediatric cardiologist for TAPVR?
Children who were born with TAPVR and had it repaired must continue to see a pediatric cardiologist regularly. It is important that children who were born with total anomalous pulmonary venous return continue to see a cardiologist. We will help patients transition care to an adult congenital heart disease specialist.
