What are the most common causes of aortic stenosis?
Aortic stenosis is a common valvular disorder, especially in the elderly population, causing left ventricular outflow obstruction.
Etiologies include congenital (bicuspid/unicuspid), calcific, and rheumatic disease.
Age-related degenerative calcific aortic stenosis is the most common cause in adults.
Aortic stenosis is more common in men than women.
