During the past eight years, 46 of the 106 patients who underwent mitral valve replacement were associated with tricuspid insufficiency. No surgical correction was performed (14 cases) in cases of slight tricuspid insufficiency. Tricuspid annuloplasty (11 cases) or valve replacement (21 cases) was employed according to the severity of insufficiency. In the non-repair group, the mortality rate was fairly low (21 per cent), but the postoperative status was the least satisfactory by the NYHA classification. Tricuspid insufficiency was significantly reduced only in two of these 14 cases after the mitral valve replacement. In the tricuspid annuloplasty group, although the technique of tricuspid annuloplasty did not always correct insufficiency completely, only one patient died of residual insufficiency. The cardiac output measured with Minnesota Impedance Cardiograph increased postoperatively in proportion to stress in this group. In the tricuspid valve replacement group, cardiac catheterization studies revealed hemodynamic improvement at rest in all, but cardiac output during exercise remained unchanged or decreased in some cases. Now we consider that tricuspid insufficiency with advanced mitral valve disease, even of a slight degree, should be surgically treated and that annuloplasty has more obvious hemodynamic benefits than valve replacement.
