[Surgical treatment of patients with triple valvular heart disease--a clinical study of triple valve replacement].

Triple valve replacement were performed on 14 cases from 1972 to 1987 in our department in Nihon University School of Medicine. Hemodynamic data and the function of other organs were analysed. 5 cases were dead. Causes of death were LOS in four and respiratory failure in one. Although preoperative clinical status were class III and IV in NYHA, postoperative clinical status improved in I and II except dead cases. There were significant differences between pre and postoperative valves of PAm, PCWP and CI, but of RAm RVEDP and EF. The reason why these cardiac function did not recover enough was myocardial degeneration. The respiratory, renal and liver function was clearly improved after operation except hemolysis. In conclusion, it is recommended that, in cases of severe triple valve disease, triple valve replacement should be performed with SJM valve to get satisfactory hemodynamic improvement.
