Aortic Stenosis Causes & Risks

Causes

The main causes of aortic stenosis include:

  • A birth defect of the aortic valve, which normally has three cusps:
    • An aortic valve that has only one cusp or is otherwise stenotic from birth
    • A bicuspid (two-part) aortic valve with progressive wear and tear
  • Progressive calcification of the aortic valve with age (most common in elderly)
  • Rarely, scarring of the aortic valve caused by rheumatic fever

Risk Factors

A risk factor is something that increases your chances of getting a disease or condition.

  • Sex: male
  • Family members with valvular heart disease
  • History of rheumatic fever
