AB Functional  mitral  regurgitation  (FMR)  is  a  complication  of  ischemic  or  dilated  cardiomyopathy,  occurring  secondary  to  left  ventricular  (LV)  geometrical  distortion  from  tenting,  inferobasilar  migration,  apical  displacement,  annular  dilation  and  posterior  leaflet  restriction,  and/or  regional  LV  wall  dysfunction.  MR  leads  to  a  vicious  cycle  of  LV  volume  overload,  increased  geometric  distortion  and  progressive  MR.  FMR  complicating  congestive  heart  failure  predicts  a  poor  survival.  Mitral  surgery,  to  treat  FMR  has  been  undertaken  with  an  acceptably  low  operative  mortality.  However,  the  exact  MR  surgery  (repair  or  replacement)  for  which  patient  and  what  benefit,  remains  controversial.
