What is pulmonary atresia with intact ventricular septum?

What is pulmonary atresia with intact ventricular septum?

Pulmonary atresia with intact ventricular septum (PA-IVS) is a rare form of cyanotic congenital heart malformation characterized by severe cyanosis and tachypnea.

How does pulmonary atresia affect the heart and lungs?

In pulmonary atresia, the valve between the heart and lungs (pulmonary valve) is not fully developed, which prevents forward blood flow to the lungs, and your baby doesn’t get needed oxygen. Normally, some blood enters the lungs through other passages within the heart and its arteries.

What kind of surgery is needed for pulmonary atresia?

Treatments. During surgery, doctors widen or replace the pulmonary valve and enlarge the passage to the pulmonary artery. If a baby has a ventricular septal defect, the doctor also will place a patch over the ventricular septal defect to close the hole between the two lower chambers of the heart.

How are babies with pulmonary atresia treated after birth?

Most babies with pulmonary atresia will need medication to keep the ductus arteriosus open after birth. Keeping this blood vessel open will help with blood flow to the lungs until the pulmonary valve can be repaired. Treatment for pulmonary atresia depends on its severity.

PA/IVS is a rare congenital cardiac defect that consists of atresia of the pulmonary valve resulting in an absent connection between the right ventricular outflow tract (RVOT) and pulmonary arteries as well as an IVS that allows no connection between the right and left ventricles.

Is pulmonary stenosis a serious heart condition?

People with pulmonary stenosis are more likely to have an irregular heartbeat. Unless the stenosis is severe, irregular heartbeats associated with pulmonary stenosis usually aren’t life-threatening.

Is pulmonary stenosis life threatening?

Untreated pulmonary valve stenosis can lead to a number of harmful and deadly complications. One example is right ventricular hypertrophy, or heart enlargement. This can weaken and permanently damage the heart.

Can you live without a pulmonary valve?

When the pulmonary valve is missing or does not work well, blood does not flow efficiently to the lungs to get enough oxygen. In most cases, there is also a hole between the left and right ventricles of the heart (ventricular septal defect). This defect will also lead to low-oxygen blood being pumped out to the body.

How rare is pulmonary atresia with intact ventricular septum?

Pulmonary atresia with intact ventricular septum is a rare congenital heart defect. It occurs at a rate of less than one per 10,000 live births.

Is pulmonary vein stenosis curable?

PVS is a rare but very serious disease. Children can have surgery or catheter-based interventions (balloon angioplasty or stents) to help relieve the narrowing and help blood flow better through the lungs.

Can mild pulmonary valve stenosis go away?

In children with mild degrees of pulmonary stenosis, it is common occurrence that the stenosis might improve over time. However, children with even mild pulmonary stenosis require lifelong follow-up as the pulmonary valve may become stiffer and therefore work less sometimes later on in adult life.

Does pulmonary stenosis need surgery?

Most people who have this health problem will not need surgery. Mild cases may not cause any symptoms. People with more moderate pulmonary stenosis may have symptoms such as fatigue and shortness of breath with exercise.

How long does a pulmonary valve last?

In adults, the life span of a pulmonary valve prosthesis ranges between 15 and 30 years.
