title: [Reoperation about recurrent heart valve disease in 221 cases].
abstract: OBJECTIVE
  To retrospectively review the experience of reoperation after closed mitral commissurotomy, valvuloplasty, perivalvular leakage and dysfunction of bioprosthetic valve in 221 cases.
  
  
  METHODS
  Two hundred and twenty-one patients underwent heart valve reoperation from January 1998 to August 2005. Among them, 8 cases was emergency operation. The reasons of reoperation included 105 cases suffered from mitral valve restenosis after closed mitral commisurotomy, 37 cases suffered from valve lesion after mitral or aortic valvuloplasty, 29 cases suffered from perivalvular leakage after valve replacement. Eighteen cases suffered from bioprosthetic valve decline, 9 cases suffered from dysfunction of machine valve, 7 cases suffered from tricuspid insufficiency of Ebstein, 5 cases suffered from prosthetic valve endocarditis and 11 cases suffered from other valve disease. The re-operations were mitral valve replacement, mitral and aortic valve replacement, aortic valve replacement and tricuspid valve replacement. The interval from first operation to next operation was 1 - 21 years.
  
  
  RESULTS
  The early-stage postoperative mortality was 8.6% (19/221). And the reasons were low cardiac output syndrome, arrhythmia, multiple organ dysfunction failure (MODF) and renal failure. Among these the emergency operative mortality was 3/8. And the mortality was 14.5% (9/62) in class IV of cardiac function (NYHA).
  
  
  CONCLUSIONS
  The risk factors of reoperation about heart valve disease include emergency operation, low preoperative cardiac function, MODF, long time of cardiopulmonary bypass and aortic blocking. Therefore it is emphasized that mastering and treating the risk factors promptly, which could decrease the mortality and incidence of complication.
