Definition
By Mayo Clinic staffPulmonary valve stenosis is a condition in which the flow of blood from your heart to your lungs is slowed by a deformity on or near your pulmonary valve, the tissue that controls the blood flow from your heart to your lungs.
Adults occasionally have the condition as a complication of another illness, but most of the time, 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 get worse and require surgery. Fortunately, treatment is highly successful, and most people with pulmonary valve stenosis can expect to lead normal lives.
