title: Aortic valve repair for aortic regurgitation: intermediate-term results in patients with tricuspid morphology.
abstract: OBJECTIVE
  Surgical results after aortic valve repair in patients with aortic regurgitation (AR) of tricuspid valve morphology and with no evidence of aortic root disease have not yet been clarified.
  
  
  METHODS
  Between January 1994 and June 2001, aortic valve repair was performed in 40 patients (eight females, 32 males; mean age 61.0 +/- 10.5 years) of this type. Surgical results and follow up data were summarized after aortic valve repair (for AR) in these patients.
  
  
  RESULTS
  One patient died in hospital (mortality 2.5%). The mean cardiopulmonary bypass time was 143.5 +/- 47.4 min, and mean aortic cross-clamp time 99.8 +/- 34.3 min. At follow up, the mean AR grade was 1.5 +/- 0.8 and mean NYHA class 1.0 +/- 0; both parameters showed significant improvement compared to preoperative status (p < 0.0001). Survival was 94.9% at one year and 82.6% at five years. The five-year reoperation-free rate was 87%.
  
  
  CONCLUSIONS
  Aortic valve repair for AR in patients with tricuspid valve morphology is a safe procedure that provides good intermediate-term results.
