TI  - Hospital risk factors for bovine pericardial bioprosthesis valve implantation.
PG  - 113-8, 125-30
AB  - BACKGROUND: Identification of preoperative heart valve surgery risk factors aim 
      to improve surgical outcomes with the possibility to offset conditions related to 
      increased morbidity and mortality. OBJECTIVE: Intent of this study is to identify 
      hospital risk factors in patients undergoing bovine pericardial bioprosthesis 
      implantation. METHODS: Retrospective study including 703 consecutive patients who 
      underwent implantation of at least one St. Jude Medical-Biocor bovine pericardial 
      bioprosthesis between September 1991 and December 2005 at the Rio Grande do Sul 
      Cardiology Institute; 392 were aortic, 250 were mitral and 61 were mitroaortic. 
      Characteristics analyzed were gender, age, body mass index, NYHA (New York Heart 
      Association) functional class, ejection fraction, valve lesions, systemic 
      hypertension, diabetes mellitus, kidney function, arrhythmias, prior heart 
      surgery, coronary artery bypass graft, tricuspid valve surgery and elective, 
      urgent or emergency surgery. Main outcome was in-hospital mortality. Relationship 
      between risk factors and in-hospital mortality was analyzed using logistic 
      regression. RESULTS: Were 101 (14.3%) in-hospital deaths. Characteristics with 
      significant relationship to increased mortality were female gender (p<0.001), age 
      over 70 years (p=0.004), atrial fibrillation (p=0.006), diabetes mellitus 
      (p=0.043), creatinine > 2.4 mg/dl (p=0.004), functional class IV (p<0.001), 
      mitral valve lesion (p<0.001), previous heart surgery (p=0.005), tricuspid valve 
      surgery (p<0.001) and emergency surgery (p<0.001). CONCLUSION: Mortality rate 
      observed is accepted by literature and is justifiable due to the high prevalence 
      of risk factors, showing an increased significance level for female gender, age 
      above 70, functional class IV, tricuspid valve repairs and emergency surgery. 
      Offsetting these factors could contribute to reduced in-hospital mortality for 
      valve surgery.
