Pulmonary valve stenosis is a condition where a deformity on or near your pulmonary valve narrows the opening of the pulmonary valve and slows blood flow. The pulmonary valve is located between the lower right chamber of the heart (right ventricle) and the pulmonary arteries. Adults sometimes have pulmonary valve stenosis as a complication of another disease, but most often pulmonary valve stenosis develops before birth as a congenital heart defect.
Pulmonary valve stenosis ranges from mild and symptomless to severe. Mild pulmonary stenosis doesn’t usually work over time, but moderate and severe cases can work and require surgery. Fortunately, treatment is generally very effective, and most people with pulmonary valve stenosis can hope to lead normal lives. Stenosis, pulmonary valve treatment in hyderabad
The signs and symptoms of pulmonary valve stenosis vary depending on the extent of the obstruction. People with mild pulmonary stenosis usually have no symptoms. People with more severe stenosis can often notice the first symptoms during exercise.
Signs and symptoms of pulmonary valve stenosis can include:
- Heart murmur – an abnormal wheezing heard through a stethoscope caused by turbulent blood flow
- Shortness of breath, especially while exercising
- Chest pain

- Pulmonary valve stenosis usually occurs when the pulmonary valve does not develop properly during fetal development. Babies with this condition can have other congenital heart defects as well. It is not known what is causing the valve to develop abnormally. Stenosis, pulmonary valve treatment in hyderabad
Normal pulmonary valve anatomy
The pulmonary valve is made up of three thin pieces of tissue called cusps, arranged in a circle. With each heartbeat, the valve opens in the direction of blood flow – into the pulmonary artery and on to the lungs – and then closes to prevent blood from flowing back into the heart’s right ventricle.
Because pulmonary valve stenosis usually develops before birth, not many risk factors are known. However, certain conditions and procedures can increase your risk of developing pulmonary valve stenosis later in life, including:
- Carcinoid Syndrome
- Acute joint rhumatism
- Noonan’s Syndrome
- Replacement of the pulmonary valve
Pulmonary stenosis can be associated with:
Infection. People with heart valve problems, such as pulmonary stenosis, are at higher risk of developing bacterial infections in the inner lining of the heart (infectious endocarditis) than people without heart valve problems.
Heart pump problems. In severe pulmonary stenosis, the heart’s right ventricle needs to pump harder to force blood into the pulmonary artery. By pumping the right ventricle against increased pressure, the muscle wall of the ventricle thickens (right ventricular hypertrophy). Eventually the heart becomes stiff and can become weaker.
