title: [Retrospective analysis of 913 cases of heart valve replacement in Xinjiang area].
abstract: OBJECTIVE
  To explore the perioperative experience of heart valve replacement in Xinjiang area.
  
  
  METHODS
  A total of 913 cases underwent heart valve replacement in moderate hypothermia under cardiopulmonary bypass surgery in Xinjiang area. The clinical characteristic, indications and treatments of the patients were analyzed retrospectively.
  
  
  RESULTS
  Among all cases, the overall recovery was 868 (95.1%) cases. And 45 (4.9%) patients died of postoperative complications. The mortality had significant differences between different age groups and different NYHA classification groups. And there was no significant difference between different operation time groups and different cardiothoracic ratio groups.
  
  
  CONCLUSIONS
  Valve replacement surgery is still an effective therapy for valvular diseases in Xinjiang area. Enhancing preoperative care for elders and patients with poor cardiac function can decrease the perioperative complications and mortality rate so as to improve the surgical efficacies.
