Pulmonary valve stenosis

Pulmonary valve stenosis
Pulmonary valve stenosis

Pulmonary valve stenosis refers to an obstruction of the valve that is located within the upper right chamber of the heart (right ventricle) and the lung arteries (pulmonary arteries). When a heart valve is narrowed the valve’s flaps (cusps) could become stiff or stiff. This can reduce heart valve blood flow¹.

Typically, pulmonary valve dysfunction is a result of a heart issue that occurs prior to birth (congenital heart defects). However, adult patients may experience pulmonary valve stenosis due to an outcome of another condition.

The severity of pulmonary valve stenosis varies from moderate to severe. A few people suffering from moderate pulmonary valve stenosis may not have any symptoms and might just require periodic doctor’s visits. A severe and moderate pulmonary valve stenosis could require a procedure to fix and replace the valve.



The symptoms and signs vary according to the degree of blood flow is affected. A few people suffering from mild pulmonary stenosis do not show symptoms. People with more severe pulmonary stenosis might first experience symptoms when exercising.

Signs and symptoms could be:

Babies born with pulmonary valve stenosis as well as other heart defects that are congenital may be to be blue (cyanotic).

When to seek medical help?

Discuss with your doctor If either of your children suffers from:

Should you suspect that your kid is suffering from pulmonary stenosis, or another heart issue timely diagnosis and treatment may lower the chance of complications.


Pulmonary valve stenosis is often caused by a heart defect that is congenital. The cause of the problem is not clear. The pulmonary valve does not develop in a proper way when the baby grows inside the womb.

The pulmonary valve is comprised of three small pieces of tissue, known as flaps (cusps). The cusps can be opened and closed at every heartbeat, and help ensure that blood flows in the correct direction.

In the case of pulmonary valve stenosis one or more cusps could be thick or stiff or might connect in fusion. This means that the valve isn’t fully open. The valve’s smaller opening makes it difficult for blood to drain out of the lower chamber of the heart (right ventricle). Pressure rises inside the right ventricle when it tries to pump blood through the narrower opening. The pressure increase causes an increase in heart strain that ultimately results in the right ventricle’s muscular wall getting thicker.

Risk factors

Conditions or diseases that could raise the chance of developing pulmonary valve stenosis are:


Potential complications of pulmonary narrowing include:


The condition is typically detected in the early years of childhood. However, it could not be discovered until later in life.

The doctor will utilize the stethoscope for listening to your child’s or your child’s heart. A squealing sound (murmur) is caused by the choppy (turbulent) circulation of blood over the valve could be heard.


The tests to determine if you have pulmonary valve stenosis can consist of:


If you suffer from moderate pulmonary valve stenosis that does not cause symptoms, you may just require regular doctor’s checks.

If you suffer from severe or moderate pulmonary valve narrowing you might require an operation on your heart or surgery. The kind of procedure or procedure you undergo will depend on the overall condition of your body as well as the appearance of the pulmonary valve.

Heart surgeries and procedures used in treating the condition of pulmonary valve stenosis are:


Lifestyle and home solutions for home and lifestyle

If you suffer from valve disease it is important to ensure that you are keeping your heart in good health. Certain lifestyle choices can lower the chance of developing different types of heart disease or even having heart attacks.

Changes in your lifestyle that you should talk to your doctor might include:
