Pulmonary Valve Stenosis—Child

Pulmonary Valve Stenosis—Child

(Pulmonary Stenosis—Child)

Definition

Pulmonary valve stenosis is a problem with a valve in the heart. They valve is thickened or cannot open as wide as it should. This can:

  • Decrease the amount of blood that reaches the lungs, which lowers the amount of blood that is available to pick up oxygen
  • Increase the workload of the right side of the heart
  • Cause blood to back up into the heart

Causes

This problem is present at birth. It happens when the valve has not developed as it should. It is not known why this happens. Genes, the environment, and dietary factors may play a role.

Treatment

Mild stenosis may not need treatment right away. The doctor will monitor the child for any changes.

In others, the goal of treatment is to ease symptoms and prevent damage. Activity levels may need to be lowered.

Surgery may be done to repair or replace the problem valve. Choices are:

  • Balloon valvuloplasty to pass a balloon to the valve and inflates it to open the valve
