What is the difference between pulmonary fibrosis and stenosis?

See below: Pulmonary fibrosis is, generally speaking, scarring of the lungs. Certain types progress faster than others. There is no such thing as pulmonary stenosis (narrowing). You can have a narrowing of the airways which is a completely different problem and may be treated with stents. And refers to the large airways so is different from asthma and copd. Hope this is not too confusing!

Heart versus lungs: Pulmonary fibrosis is a disease affecting older patients. The lung develops scar tissue and becomes stiff over time, causing impaired breathing and eventually death. There is no cure. Pulmonary stenosis is a narrowing of a heart valve that separates the right side of the heart and the arteries it empties into supplying the lungs. This cause heart strain. It is fixed with surgery.

FIFROSIS INLUNGS,STE: Fidrosis is inthe lungs due to scarring, but pulmonary stenosis is narrowing of the pulmonary valve inthe heart both are completely different conditions in different organs.
