PY - 2016 T2 - Anesthesiology Core Review: Part Two Advanced Exam AB - Chronic aortic insufficiency (AI) is typically the result of congenital conditions such as a bicuspid aortic valve, rheumatic disease, connective tissue disorders (e.g., Marfan’s syndrome), or cystic medical necrosis. Acute AI is rarer and carries a poor prognosis. Aortic dissections, trauma, and bacterial endocarditis can lead to acute aortic insufficiency. Both processes lead to malcoaptation of the aortic valve leaflets by causing abnormalities in the leaflets themselves or dilation of the AV annulus, the aortic root, or both.
