Aortic stenosis can be either congenital or acquired, and its common causes vary between different age groups and between different populations.  Rheumatic heart disease remains the most common cause of aortic stenosis worldwide.  Calcification of the aortic valve is the most common cause of aortic stenosis in North America and Europe. While calcification of congenital bicuspid aortic valve is the most common cause of aortic stenosis in people less than 70 years of age, acquired degenerative calcific aortic stenosis is the most common cause in older patients above the age of 70 years.
