TI  - Reoperations on prosthetic heart valves: an analysis of outcome.
PG  - 791-6
AB  - To evaluate risks and complications of reoperations on prosthetic heart valves, 
      we reviewed data on 70 patients who underwent reoperations because of prosthetic 
      valve malfunction. Overall hospital mortality was 13% (9/70 patients). The common 
      cause of death was low cardiac output syndrome following surgery (4 patients). 
      Respiratory failure and mediastinal infection accounted for 2 deaths each, and 
      neurological complication for 1 death. However, hospital mortality was different 
      according to the risk factors; reoperations for prosthetic valve endocarditis 
      (18%, p < 0.05), advanced New York Heart Association (NYHA) class (50%, p < 
      0.001), and emergency operation (33%, p < 0.005) were the significant risk 
      factors. In contrast, advanced age, female sex, type of prosthesis, valve 
      position, and diagnosis (leak, structural deterioration, or valve thrombosis) did 
      not appear to be significant risk factors. There were 7 late deaths (4 
      valve-related, 2 cardiac, and 1 noncardiac). Inasmuch as emergency operation, 
      advanced NYHA class, and prosthetic valve endocarditis affected hospital 
      mortality, these factors contributed to late death. Actuarial survival rate and 
      freedom from valve-related mortality at 10 years were 75.8 +/- 2.8% and 87.2 +/- 
      2.3%, respectively. There were 8 valve-related complications, and freedom from 
      valve-related complications at 10 years was 73.5 +/- 3.5%. As judged by these 
      data, hospital mortality and late survival can be improved if hemodynamic 
      conditions leading to myocardial damage can be prevented.
