Pulmonary Stenosis

Pulmonary Stenosis: Pulmonary Stenosis is the narrowing of the valve that lets blood flow from the lower-right chamber (the right ventricle) into the lungs. When this valve narrows, the right ventricle has to work harder and it becomes enlarged. Children with mild stenosis usually do not need surgery, but they should be watched carefully and see their doctor regularly. But if a child is cyanotic (bluish), the valve must be widened right away – either through open heart valve surgery or balloon valvuloplasty.
