Symptoms

Pulmonary valve stenosis signs and symptoms vary, depending on how much blood flow is blocked. Some people with mild pulmonary stenosis don't have symptoms. Those with more-severe pulmonary stenosis may first notice symptoms while exercising.

Pulmonary valve stenosis signs and symptoms may include:

• A whooshing sound (murmur) that can be heard with a stethoscope
• Fatigue
• Shortness of breath, especially during activity
• Chest pain
• Loss of consciousness (fainting)

Babies with pulmonary valve stenosis and other congenital heart defects may appear blue (cyanotic).

When to see a doctor

Talk to your doctor if you or your child has:

• Shortness of breath
• Chest pain
• Fainting

If you or your child has pulmonary stenosis or another heart problem, prompt diagnosis and treatment can help reduce the risk of complications.
