Not all children with pulmonary stenosis need treatment. It depends on how severe their condition is. But all children with this condition need lifelong care to monitor their condition in case it starts to get worse.

Some children with pulmonary stenosis need treatment right away because their heart cannot deliver enough blood and oxygen to the rest of their body.

To meet your child's long-term healthcare needs, we have a special Adult Congenital Heart Disease Program to transition your child to adult care when they're ready.

Pulmonary Stenosis Treatment Options

If the stenosis is mild, sometimes your child may not need any kind of treatment, surgery or medicine.

If the stenosis is more severe, treatment may be done in the catheterization lab using a balloon procedure. A balloon is inserted across the valve. When the balloon is inflated, the valve is stretched open. Then, the balloon is removed. This is called balloon valvuloplasty.

Some children need surgery to open the valve and increase blood flow to the lungs. If the stenosis is severe enough, your child may need their valve replaced.
