Pulmonary stenosis is usually a congenital defect and may be associated with other cardiovascular congenital defects.
The treatment for severe pulmonary stenosis is the surgical correction of the defect.
The most common congenital defect of the valves in children is a narrowing of the pulmonary valve (the valve opening to the pulmonary artery), called pulmonary stenosis.
Persons may have mild pulmonary stenosis without being conscious of the defect or may experience difficulty in breathing and have a tendency to faint after exertion.
As a result of the obstruction imposed by the pulmonary stenosis, deoxygenated venous blood is shunted from the right to the left side of the heart into the arterial circulation.
Pulmonary stenosis, narrowing of either the pulmonary valve the valve through which blood flows from the right ventricle, or lower chamber, of the heart on its way to the lungs or the infundibulum, or of both.
Both the aorta and the pulmonary artery may originate from the right ventricle; this form of abnormal origin of the arteries usually is associated with a ventricular septal defect and, on occasion, pulmonary stenosis.
Pulmonary stenosis is more common in patients with PTPN11 mutations.
Unfortunately, we could encounter only one case with pulmonary stenosis.
Pulmonary stenosis, when significant, results in delayed ventricular filling and compensatory RV hypertrophy.
