==Etiology==
*Congenital pulmonic stenosis is most common.
*Rheumatic involvement is rare, is usually part of  multivalvular involvement, rarely leads to serious deformity.
*Carcinoid plaques can be present in the carcinoid syndrome. These result in constriction of the pulmonic valve ring, retraction and fusion of the valve cusps.
==Anatomy==
*Typically the valve is domed shaped with fused commissures.
*If the foramen ovale is patent, then right to left shunting can occur at the atrial level.
*If there is pulmonary atresia with an intact ventricular septum then these patients die soon after birth.
