Overview

The most common risk factor for the subsequent development of aortic stenosis arises is a congenital bicuspid aortic valve.

Risk factors

  • Common risk factors for the development of aortic stenosis include:
  • Age-related progressive calcification of the normal tricuspid aortic valve (>50% of cases).
  • Congenital bicuspid aortic valve that may subsequently become calcified later in life (30-40% of cases). Normal aortic valve have three leafs (tricuspid), but some valves have two leafs (bicuspid). Typically, aortic stenosis due to calcification of a bicuspid valve appears earlier, in the 40s and 50s, whereas that due to calcification of a normal valve appears later, in the 70s and 80s.
  • Acute rheumatic fever (less than 10% of cases).
  • Other risk factors that may speed up the progression of aortic stenosis include:
