Pulmonary Stenosis is a condition of the Heart that deals with a narrowing or stenosis of the pulmonary heart valve.

There are 4 main valves in the Heart:

1.)  Tricuspid Valve
2.)  Pulmonary Valve
3.)  Mitral Valve
4.)  Aortic Valve

Stenosis means a narrowing – in this case of a area where blood can travel through in the heart.

Pulmonary stenosis can cause an increase in right ventricle pressure making it more difficult for blood to flow through the valve.

Blood from pulmonary valve goes from the right ventricle of the heart into the Lungs.

The right side of the heart often is required to work harder inorder to push the deoxygenated to the lungs.

The blood then is oxygenated to be returned to the heart to be sent to the body.

Symptoms

1.) Mild Cases

• Typically no symptoms

2.) Moderate to Severe

• Difficulty breathing
• Shortness of breath on exertion
• Heart Murmur that can radiate towards the left shoulder, inceases with inspiration

Diagnosis

EKG is moderately helpful as are X-rays

Echocardiography/Doppler is essential for diagnosis

Treatment

• For mild stenosis – no treatment is required
• Percutaneous balloon valvuloplasty
• Surgical valve replacement
