AB Ischemic  mitral  regurgitation  (IMR),  often  termed  functional  mitral  regurgitation,  is  mitral  insufficiency  as  a  result  of  myocardial  ischemia  or  infarction.  By  definition,  the  mitral  valve  leaflets  are  structurally  normal  in  IMR.  The  malcoaptation  of  the  leaflets  and  resultant  regurgitation  of  the  mitral  valve  in  IMR  is  a  result  of  either  acute  papillary  muscle  dysfunction  or  rupture,  or  chronic  changes  with  left  ventricular  remodeling  and  subsequent  changes  in  geometry.
