TI  - Intermediate term evaluation of Starr-Edwards ball valves in the mitral position.
PG  - 43-7
AB  - The Model 6120 ball valve prosthesis introduced in 1965 is still strongly 
      supported as a mitral valve substitute in many centers around the world. A 
      current reassessment of the performance of this prosthesis is therefore pertinent 
      to current medical practice. In this institution since 1974, 227 Starr-Edwards 
      caged ball valves have been implanted in the mitral position during isolated 
      valve replacement. Two models of caged ball valves were used concurrently: the 
      silastic ball valve in 108 patients (48%) and the composite strut "tract" valve 
      in 119 (52%). Hospital mortality was 7%, and 8-year survival (standard error) was 
      74 (6%), with 100% follow-up, documenting 752 total patient-years. No late deaths 
      were known to be valve related, and there were no cases of prosthetic thrombosis. 
      The actuarial estimate of patients free from thromboembolism at 8 years was 89 
      (4%) with a linearized rate of 1.3% per year. At the most recent follow-up, 95% 
      of the patients were in the New York Heart Association (NYHA) Classes I or II. 
      These good results were partly due to an awareness at operation of ventricular 
      outflow tract size requirements and to strict control of postoperative 
      anticoagulation. We conclude that the Starr-Edwards ball valve is the mitral 
      valve of choice in the young patient who is able to take anticoagulation drugs 
      and has a left ventricular outflow tract of satisfactory size.
