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.
