Pulmonary Stenosis

Pulmonary stenosis is a congenital condition of the heart where stenosis or narrowing of the pulmonary valve occurs. This leads to reduced flow towards the lung. Pulmonary valve connects the lower right heart chamber (right ventricle) and the pulmonary arteries. The pulmonary artery function is to carry less oxygenated blood towards the lungs.

  3. Other congenital heart defects.

  4. Genetic disorder.

What are the Various Risk Factors Associated with Pulmonary Stenosis?

There aren’t many known risk factors for pulmonary stenos because it usually develops before birth. However, certain conditions and procedures may increase your risks of pulmonary stenosi which include.

  1. Pulmonary valve replacement

  2. Noonan syndrome

  3. Carcinoid syndrome of the digestive system which triggers the release of serotonin chemicals from the growths of carcinoid in the digestive system.

  4. Rheumatic fever

How can you Prevent Pulmonary Stenosi?

Pulmonary stenos can be prevented by following a heart-healthy lifestyle which includes:

  1. Quitting smoking.

  2. Doing exercise regularly

  3. Limiting the intake of sodium salt, cholesterol and fat
