Pulmonary Stenosis

Pulmonary Stenosis is an abnormal narrowing of the pulmonary valve, or pulmonary artery, which can block the flow of blood into the lungs. In the case of pulmonary stenosis, blood flow to the lungs is reduced, which lessens the amount of blood getting oxygenated. The condition can vary in its severity depending on the amount of narrowing and its effect on the blood supply to the lungs.

If the disorder is mild, there may not be any symptoms. However, symptoms can be aggravated by exercise and can include:

•    Fatigue
•    Fainting
•    Chest pain
•    Shortness of breath
•    Bluish coloration to the skin
•    Poor weight gain or failure to thrive in infants

In most cases, pulmonary stenosis is a congenital abnormality, or a heredity disease that is present at birth. However, it can also occur later in life as a result of conditions that cause damage to or scarring of the heart valves such as rheumatic fever or endocarditis.

In some cases, treatment may not be required. If the individual is of pre-school age, surgical repair of the defect is usually performed.

Talk to your doctor if you or your child suffers from symptoms of pulmonary stenosis for an accurate diagnosis and treatment plan.
