title: [Determinants factors of hospital morbidity and mortality after reintervention of valve replacement].
abstract: BACKGROUND
  Valve surgery involves valvular substitutes that expose to different types of complications that can lead to re subsequent interventions.
  
  
  OBJECTIVE
  was to identify the predictors factors of in-hospital morbidity and mortality of re interventions after valve replacement.
  
  
  METHODS
  Retrospective study of 73 consecutive patients who underwent a re valve replacement between 1985 and 2010 in the Cardiovascular Surgical department of La Rabta hospital.
  
  
  RESULTS
  The average age at further surgery was 44 years ( 15-80 years) and sex ratio of 0.87 . The average time between interventions was 10 years (3 days -33 years). Different etiologies were found prosthesis thrombosis (36.9% ). The overall hospital mortality was 36.9 % , 11 intraoperative deaths and 16 immediate postoperative deaths.
  
  
  CONCLUSIONS
  The iterative intervention of valve replacement surgery is increasingly mastered by the surgical team. According to this study , the prognosis depends mainly on the patient preoperatively state, the cause of further surgery and its mode of occurrence.
