Y1 - 2016 N1 - T2 - Anesthesiology Core Review: Part Two Advanced Exam AB - Epidemiological studies have determined that more than one in eight people aged 75 and older have moderate or severe aortic stenosis (AS). The most common cause of aortic stenosis is progressive calcification and senile degeneration. Congenital defects—particularly bicuspid aortic valves—also increase the risk of stenosis. Rheumatic heart disease also predisposes to AS but is almost always linked to significant mitral valve disease. Cardiac auscultation reveals a systolic ejection murmur that radiates to the carotid artery.
