Categories: Pathology

Stenosis is the medical word to describe a narrowing or tightening where there should not be one.  This can happen in different places in the body, and cause different problems depending on where it is. Examples include valve stenosis, artery stenosis, and spinal stenosis.  Coronary artery disease causes stenosis in the arteries that bring blood to the heart. This causes angina. The valves of the heart can become stenotic for different reasons, and cause shortness of breath or chest pain and heart murmurs.
