title: Influence of valve prosthesis type on early mortality in patients undergoing valve surgery.
abstract: OBJECTIVE
  To evaluate the influence of the type of prosthesis in-hospital mortality in the post-operative period in patients who had valve replacement.
  
  
  METHODS
  A cross-sectional data, such as gender, origin, age, etiology, echocardiograph data, the type of surgery performed and the prosthesis used in cases of valve replacement were analyzed retrospectively.
  
  
  RESULTS
  We reviewed 353 charts of patients who underwent valve replacement surgery. The mean age was 41.87±17.9 years. Regarding gender, 52.8% were female. As for the origin, 61.1% came from small cities within the state. Of all patients, 58.5% suffered from rheumatic disease. Assessing the type of prosthesis implanted, 70% held replace by bioprosthesis and 30% metallic. The hospital mortality in this study was 11%, with no significant difference between the types of prosthesis utilized.
  
  
  CONCLUSIONS
  The type of implant used had no effect on in-hospital mortality.
