Pulmonary Valve Stenosis

The pulmonary valve is situated between the lower right heart chamber (right ventricle) and the pulmonary arteria’sPulmonary valve stenosis is a medical condition wherein there is a narrowing of the pulmonary valve. This, in turn, reduces the blood flow. Pulmonary valve stenosis is caused by several factors such as genetic history, rheumatic fever, etc. 

The two most common treatment methods for pulmonary valve stenosis are balloon valvuloplasty and open-heart surgery. 

What is pulmonary valve stenosis?

Pulmonary valve stenosis is a condition in which, the pulmonary valve in the  heart does not open wide enough to let the blood in or out of our heart. This constricts blood flow. The pulmonary valve is located between the pulmonary artery and the right ventricle. In mild cases, pulmonary valve stenosis does not require surgical intervention and may not even cause any symptoms . But in moderate to severe cases, surgery is required. 

Pulmonary valve stenosis is a congenital disease and is most commonly found in children. In adults, this condition occurs due to other medical conditions. This condition can be diagnosed in early childhood. However, sometimes it may not be diagnosed until much later. 

Diagnostic tests include:

Physical examination and identification of a murmur 

Electrocardiogram – In this test, electrodes are put on a person’s chest, wrists and ankles, and these measure the electrical activity in the heart. This will help determine if the right ventricle has become thick.

Echocardiogram – This test is used to test the structure and functioning of the pulmonary valve. Sound waves on your heart help produce images on a screen

Other imaging tests: CT and MRI scans are used sometimes to confirm the diagnosis of pulmonary valve stenosis.

Cardiac catheterization: CT and MRI scans – The imaging from these scans can help diagnose pulmonary valve stenosis.

How is pulmonary valve stenosis treated?

There are two treatment options when it comes to pulmonary valve stenosis. These are:

  • Balloon Valvuloplasty – In this procedure, the doctor places a small tube with a non-inflated balloon through the vein in your leg to your pulmonary valve. Then the doctor inflates the balloon which allows the valve to expand and increase the blood flow. Once this is achieved, the balloon is removed. 
  • Open-heart Surgery – When balloon valvuloplasty fails to work, then the next treatment option is open-heart surgery. This includes either replacing the valve with an artificial valve or repairing one’s pulmonary artery.
