Pulmonary valve stenosis is a narrowing of the valve between the lower right heart chamber and the lung arteries. In a narrowed heart valve, the valve flaps may become thick or stiff. This reduces blood flow through the valve.
Pulmonary stenosis, also called PS, is caused by a narrowing of the pulmonary valve opening. PS restricts blood flow from the lower right chamber (ventricle) to the pulmonary arteries, which deliver blood to the lungs. It’s most commonly the result of a congenital heart defect.
What is it? The pulmonary valve opens to let blood flow from the right ventricle to the lungs. Narrowing of the pulmonary valve (valvar pulmonary stenosis) causes the right ventricle to pump harder to get blood past the blockage.

If you have mild pulmonary valve stenosis without symptoms, you may only need occasional health checkups. If you have moderate or severe pulmonary valve stenosis, you may need a heart procedure or heart surgery.
Pulmonary or pulmonic stenosis is a common congenital heart defect that involves mild, moderate, or severe narrowing of the right ventricular outflow tract, pulmonary valve, or pulmonary arteries, which restricts blood flow from the heart to the lungs.
Types of pulmonary valve disease include: Pulmonary valve stenosis. Narrowing of the pulmonary valve reduces the blood flow from the heart to the pulmonary artery and lungs. Pulmonary valve regurgitation. The flaps of the pulmonary valve don't close tightly. Blood moves backward into the right lower heart chamber, called the right ventricle ...
Pulmonary valve stenosis (PVS) is a heart valve disorder. Blood going from the heart to the lungs goes through the pulmonary valve, whose purpose is to prevent blood from flowing back to the heart. In pulmonary valve stenosis this opening is too narrow, leading to a reduction of flow of blood to the lungs. [1][5]
Pulmonary stenosis, also called PS, is caused by a narrowing of the pulmonary valve opening. PS restricts blood flow from the lower right chamber (ventricle) to the pulmonary arteries, which deliver blood to the lungs. It’s most commonly the result of a congenital heart defect.
Pulmonic stenosis (PS) is narrowing of the pulmonary outflow tract causing obstruction of blood flow from the right ventricle to the pulmonary artery during systole. Most cases are congenital; many remain asymptomatic until adulthood.
