TI  - Thirty years experience with heart valve surgery: isolated mitral valve 
      replacement.
PG  - 806-12
AB  - BACKGROUND: Thirty years have elapsed since the commencement of open-heart 
      surgery in South Australia. A retrospective study was performed to evaluate 
      mortality and complication rates and to identify factors associated with poor 
      outcomes in all patients who underwent prosthetic mitral valve replacement during 
      this period. METHODS: Questionnaires and personal contact have been used to 
      generate a combined database of pre-operative and post-operative information and 
      long-term follow-up on 938 patients who underwent isolated prosthetic mitral 
      valve replacement at the Cardio-Thoracic Surgical Unit of the Royal Adelaide 
      Hospital between 1963 and 1993. RESULTS: Complete survival follow-up data were 
      obtained for 92% (865) of the patients. The Starr-Edwards valve was used in 95% 
      (891) of the patients, a Bjork-Shiley prosthesis in 2.5% (23) of the patients, 
      and only 24 (2.5%) other valves were inserted. The hospital mortality rate for 
      the 30-year period was 4.7%. The mean age of the patients who underwent surgery 
      was greater in each of the three successive decades. A long-term survival 
      advantage was observed for patients with mitral stenosis, however, survival was 
      significantly shorter for patients with higher New York Heart Association (NYHA) 
      functional classifications and for patients in pre-operative atrial fibrillation. 
      Pre-operative dyspnoea was significantly improved following mitral valve 
      replacement. The rates of postoperative haemorrhagic and embolic complications 
      were low by comparison with other published series. CONCLUSION: Mitral valve 
      recipients do not regain a normalized life expectancy, but risk factors that 
      determine long-term survival can be identified pre-operatively to aid appropriate 
      patient selection.
