Diseases and Conditions
Pulmonary valve stenosis
Pulmonary valve stenosis is a condition in which a deformity on or near your pulmonary valve, the valve that influences the blood flow from your heart to your lungs, slows the blood flow. Adults occasionally have the condition as a complication of another illness, but mostly, pulmonary valve stenosis develops before birth as a congenital heart defect.
Pulmonary valve stenosis ranges from mild and without symptoms to severe. Mild pulmonary stenosis doesn't usually worsen over time, but moderate and severe cases may worsen and require surgery. Fortunately, treatment is highly successful, and most people with pulmonary valve stenosis can expect to lead normal lives.
