title: Intact Medtronic and Carpentier Edwards S.A.V.: clinical and hemodynamic outcomes over 13 years.
abstract: We report on 215 consecutive patients with isolated aortic replacement of which 91 received an Intact Medtronic (IM) prosthesis and 124 a Carpentier Edwards SAV. (CE). More than 50% of patients were over 70 years old. Follow-up was complete for 95% of patients. Mean follow-up was 6.04 years (16 days-13 years); a total of 1244 patient-years (IM 6.61years, 590 patient-years, CE 5.95 years, 670 patient-years).
  
  
  RESULTS
  the following results are expressed for IM and CE groups respectively. Early mortality: 3.3% and 8.13%. Late mortality: 23 and 27 patients. Survival at 13 years: 53.31+/-7.63% and 47.47+/-7.9%. Major thromboembolism: 0.34% and 0.30% per patient-year. SVD: 0.16% and 0.14% per patient-year. Endocarditis: 0.33% and 0.29%. Re-operation: 0.5% and 0.44%. Over 95% of patients are re-operation free at 13 years.
  
  
  CONCLUSIONS
  Intact and Carpentier valves had similar durability and clinical/hemodynamic results. Both have proved excellent aortic valve substitutes in elderly patients.
