Pulmonary atresia treatment

Pulmonary atresia is a very rare birth defect of the pulmonary valve. Sometimes the pulmonary valve is missing completely; other times the valve is blocked. Normally, the pulmonary valve acts like a door that allows blood to flow from the right ventricle through the pulmonary artery to the lungs to pick up oxygen.


Initial treatment of pulmonary atresia focuses on keeping the ductus arteriosus open with a medication called prostaglandins. The ductus arteriosus, a connection between the pulmonary artery and aorta, normally closes soon after birth. Keeping it open allows blood to keep blood flowing to the lungs. If the baby does not have a ventricular septal defect (VSD)or an atrial septal defect (ASD), an emergency balloon atrial septostomy will be performed. This will allow blood on the right side of the heart to get to the left side of the heart so it can be pumped out to the body.


Your child’s pediatric cardiologist may perform a cardiac catheterization. In this procedure, the cardiologist inserts a catheter — a long, thin tube — into a large vein, threads it up to the heart and injects dye to see the heart’s structures. The catherization will allow the cardiologist to evaluate the pulmonary atresia, measure how much blood is reaching the lungs and examine the anatomy of the vessels around the heart.

Surgery will be needed to permanently create a way to get blood flow to the lungs. One option is to surgically reconstruct the right ventricular outflow tract. This can be done by opening a connection from the right ventricle to the pulmonary artery with a valved tube called a conduit, or by patching the right ventricular outflow tract. Another option is a Blalock-Taussig shunt (BT shunt), a small tube used to connect the pulmonary artery and the subclavian artery.


A child with pulmonary atresia treatment will need to see a pediatric cardiologist regularly. The child may need future surgeries. This will depend on several factors, including right ventricle size and any other defects present. A full two-ventricle repair can be done if the right ventricle is big enough.


Another option is following the single-ventricle pathway with staged surgeries to separate the oxygenated arterial circulation from the deoxygenated venous circulation. Two more surgeries — the Glenn procedureand Fontan procedure— allow blood to flow through the lungs to pick up oxygen so that it can then be distributed throughout the body.
