Definition of Pulmonary valve stenosis
Pulmonary valve stenosis is a heart valve disorder that involves the pulmonary valve.
Causes, incidence, and risk factors
Narrowing in the pulmonary valve is usually present at birth (congenital). It is caused by a problem that occurs when the unborn baby (fetus) is developing. The cause is unknown, but genetics may play a role.
Signs and tests
The health care provider may hear a when listening to your heart using a stethoscope. Murmurs are blowing, whooshing, or rasping sounds heard during a heartbeat.
Treatment
Sometimes, treatment may not be needed if the disorder is mild.
Expectations (prognosis)
About one-third of patients with mild stenosis get better, one-third stay the same, and one-third get worse. The outcome is good with successful surgery or balloon dilation. Other congenital heart defects may be a factor in the outlook.
