Pulmonary artery stenosis (narrowing) affects the artery that carries blood to your child’s lungs to pick up oxygen. To make up for this limited blood flow, right ventricle pressure can go high enough to injure heart muscle.

Dec 1, 2020 · 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.

Dec 20, 2022 · 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. In pulmonary stenosis, the …

Pulmonary artery stenosis (PAS) is a narrowing of the pulmonary artery. The pulmonary artery is a blood vessel moving blood from the right side of the heart to the lungs.

What is pulmonary stenosis? Pulmonary stenosis is a congenital (present at birth) defect that occurs due to abnormal development of the fetal heart during the first eight weeks of pregnancy. The pulmonary valve is found between the right ventricle and the pulmonary artery.

Pulmonary stenosis, or pulmonic stenosis, is a heart condition characterized by narrowing at or near the pulmonary valve. (Stenosis means narrowing of a bodily passage.) This restricts blood flow from the right ventricle—the heart’s lower right chamber—to the pulmonary artery, the vessel that carries blood to the lungs for oxygenation.

Pulmonary stenosis can be mild, moderate, severe or life-threatening. This condition is also called pulmonic stenosis or pulmonary valve stenosis. When the blockage is below the pulmonary valve because of too much muscle (muscular bundles), it’s called subpulmonic stenosis.

Pulmonary stenosis is a narrowing of the pulmonary valve that regulates the flow of blood from the right ventricle to the lungs. This narrowing may force the heart to pump harder to send blood to the lungs and lead to enlargement of the heart. The heart consists of four chambers.

Pulmonary valve stenosis is a type of heart valve disease that involves the narrowing of the pulmonary valve, which controls the flow of blood from the heart’s right ventricle into the pulmonary artery to carry blood to the lungs.

Pulmonary artery stenosis involves narrowing of the pulmonary artery, which takes blood from the heart to the lungs to pick up oxygen. Learn about our expert care.
