Pulmonary stenosis epidemiology

Demographics and Epidemiology

 * Generally, pulmonary valve stenosis is a congenital defect narrowing of the pulmonary valve (the semilunar valve that separates the right ventricule from the pulmonary artery), but occasionally, it could also be presented in adults as a complication of another illness.


 * It's one of the more common heart birth defects, and most cases are mild. If the pulmonary valve stenosis is moderate to severe, it will cause serious symptoms, requiring surgery which is highly successful.
 * It occurs in about 1 of 10 children, and females are slightly more likely to be affected than males.
