Pulmonary Stenosis

Stenosis means narrowing. Pulmonary stenosis is then a narrowing of the pulmonary valve.

Normally the pulmonary valve opens to let low oxygen blood flow from the right ventricle to the lungs where the blood is oxygenated. Because of the narrowing the right ventricle has to pump harder to get past the stenotic valve. This can sometimes lead to enlargement of the right ventricle.

Depending on the severity of the pulmonary stenosis, open heart surgery may be indicated to correct the defect. Another option may be a balloon valvuloplasty. This procedure is done in the cardiac catheterization lab. Your doctor should offer you the best option for your child.
