•Pulmonary stenosis is the obstruction of the right ventricular outflow tract caused primarily by narrowing of the infundibulum or valve stenosis. It occurs more often when the pulmonary valve is bicuspid or quadricuspid. Antenatal presentation is uncommon, as routine ultrasonography does not detect mild or moderate pulmonar stenosis because of the relative lack of pulmonar blood flow and normal fetus development.
