Epidemiology
- Most common valvular disease in developed countries
- > 50% of patients with isolated aortic stenosis also have a congenitally malformed valve (1).
- Predominant age:
- < 30 years: Congenital
- 30–70 years: Congenital or rheumatic fever
- > 70 years: Degenerative calcification of aortic valve
Prevalence
- 1.3% at 65–74 years old, 2.4% at 75–84 years old, 4% at > 84 years old (1)
