The aortic valve is situated at the opening of the left ventricle, one of the chambers of the heart. The valve opens when the ventricle pumps out blood and closes when the ventricle stops beating. This is to prevent the blood from rushing back into the ventricle. Aortic stenosis is a condition where the valve does not open completely. This can be caused by:
* Natural degeneration that causes accumulation of calcium deposits causing the opening to narrow.
* Rheumatic fever that leads to a similar situation since it can form rough scar tissues on the valve.
* Congenital deformity in which some children are born with a narrow valve.
Stenosis is an abnormal narrowing of an organ or passageway. A similar condition can occur in the spinal cord, which leads to spinal stenosis. Spinal stenosis is primarily associated with old age and requires sciatic nerve treatment including surgery. This generally requires pain management using various sciatica alternative remedies.
