title: Long-term follow-up after Carpentier-Edwards ring annuloplasty for tricuspid regurgitation.
abstract: BACKGROUND
  Use of flexible rings for tricuspid ring annuloplasty is becoming popular. This study was undertaken to evaluate Carpentier-Edwards (C-E) rigid ring annuloplasty for tricuspid regurgitation (TR), secondary to mitral valve disease and clinical outcome on a long-term basis.
  
  
  METHODS
  From December 1985 to March 1996, 45 patients with secondary TR underwent C-E ring annuloplasty. Thirty-nine patients (95.1%) were in New York Heart Association (NYHA) functional class III or IV. The mean follow-up was 96.7+/-48.5 months or 362.6 patient-years.
  
  
  RESULTS
  There were three in-hospital and nine late deaths that were not related to tricuspid annuloplasty. Actuarial survival at 10 years was 68.3%. Echocardiographic studies showed that TR was well controlled within grade 2+ in all survivors. Residual pulmonary hypertension (PH) was recognized in 9 of 21 patients (42.9%) with preoperative PH, however, no TR was seen in 6 patients. A TR grade of 2+ was observed in 3 patients. Thirty of the total survivors (96.8%) were in NYHA class I and II, but 1 patient was in NYHA class III. The actuarial rate of freedom from tricuspid valve reoperation after 10 years was 97.5%.
  
  
  CONCLUSIONS
  C-E ring annuloplasty is acceptable for repair of secondary TR and improvement in clinical status on a long-term basis.
