title: [Mitral valve replacement with a preserved subvalvular apparatus].
abstract: OBJECTIVE
  To compare the differences of mitral valve replacement between preservation and no preservation of subvalvular apparatuses for severe mitral regurgitations with mitral stenosis.
  
  
  METHODS
  We collected and analyzed the data of cardic function obtained from the cardic colour echo six months before and after operation from 41 patients with severe mitral regurgitation and mitral stenosis, 21 of whom had mitral valve replacement with the preservation of a subvalvular apparatus (MVRP), and 20 of whom had mitral valve replacement without the preservation of a subvalvular apparatus (MVR).
  
  
  RESULTS
  The internal diameter of the left ventricle, left ventricular end-diastolic volume index (LVEDVI) and left ventricular end-systolic volume index (LVESVI) were remarkably decreased in the group of MVRP as well as MVR, and the rate of the low cardic output syndrome and death obviously decreased.
  
  
  CONCLUSIONS
  MVRP is superior to MVR for severe mitral regurgitation with mitral stenosis.
