title: [Clinical analysis of tricuspid valve replacement].
abstract: OBJECTIVE
  To summarize the outcome of tricuspid valve replacement.
  
  
  METHODS
  A total of 28 patients (15 males and 13 females) underwent tricuspid valve replacement from March 2000 to February 2015 in the First Affiliated Hospital of Zhengzhou University were recruited. Among them, 16 patients were Ebstein's anomaly, 7 had rheumatic valve heart disease, 3 and 2 suffered from infective endocarditis and degenerative tricuspid lesions, respectively.
  
  
  RESULTS
  One patient died of multiple organ failure. Four patients were implanted permanent cardiac pacemaker because of third degree atrioventricular block occurring in the 5th day (2 patients) and in the 9th day (2 patients) after the operation, respectively. Twenty-seven patients were followed up from 1 month to 15 years. The prosthetic valves and permanent pacemakers worked well.
  
  
  CONCLUSIONS
  Third degree of atrioventricular block, mostly appearing in early postoperative period, is the most common and severe complication of tricuspid valve replacement. The key point for prevention of damage is to accurately identify the anatomical relationship among the tricuspid valve, atrioventricular node, and conduction bundle.
