What to know about variable heart rhythms and AFib
An Ohio State cardiac electrophysiologist shares what to know about heart rhythms and AFib.
Pulmonary valve stenosis is a narrowing of the pulmonary valve that slows blood flow from the heart to the lungs. It is a common heart defect. The heart’s pulmonary valve opens to allow blood to flow from the right ventricle to the lungs. When the pulmonary valve narrows (stenosis), this ventricle has to pump harder, which can cause higher pressure in the right ventricle. This can damage the heart muscle over time and contribute to heart failure.
Pulmonary valve stenosis is usually a congenital heart defect, and the exact cause is not known. Mothers who have rubella (German measles) during pregnancy are more likely to have babies who have congenital pulmonary valve stenosis and other heart defects. Rheumatic fever, a complication of strep throat infection, also can cause pulmonary valve stenosis.
Mild cases of pulmonary valve stenosis often cause no symptoms. More severe cases cause symptoms including:
Most people who have mild pulmonary valve stenosis do not need treatment. All cases should be regularly monitored to ensure the condition does not become serious. A stenotic pulmonary valve cannot be made normal, but the obstruction can be improved.
