PG  - 960-3
AB  - From January 1980 through December 1990, seventy one consecutive patients over 60 
      years of age (mean age 64 +/- 4 years) and 231 patients younger than 60 years 
      underwent cardiac valve replacement procedures. In the elderly group, aortic 
      valve replacement was performed in nineteen patients, mitral valve replacement in 
      thirty-three patients both aortic and mitral valve replacement in sixteen 
      patients, and both mitral and tricuspid valve replacement in three patients. 
      Aortocoronary bypass was performed in four and tricuspid annuloplasty in 19 
      patients simultaneously. Two patients were operated on emergency. As for 
      preoperative status, 63 patients (88.7%) were in New York Heart Association 
      (NYHA) Functional Class III or IV. Mechanical valves were implanted in all aortic 
      position and 16 mitral position. Bioprosthetic valves were placed in 34 mitral 
      position and 3 tricuspid position. Mean follow-up period was 42 +/- 33 months. 
      The early mortality rate was 11% (8 patients) and the actuarial survival rate was 
      88 +/- 5% at five years and 74 +/- 10% at ten years. Postoperative functional 
      improvement was excellent in 85.7% of the survivors. In the younger age group, 
      77.9% belonged to NYHA class III or IV preoperatively. The early mortality was 
      3.0% (7 patients) and the actuarial survival rate was 95 +/- 2% at five years and 
      86 +/- 2% at ten years. And postoperatively 91.3% were in NYHA class I or II. In 
      conclusion, cardiac valve replacement in the elderly can be performed with an 
      acceptable mortality and excellent functional improvement.
