Abstract
Closed mitral commissurotomy via the transventricular instrumental approach was performed
successfully in 137 patients with mitral stenosis. Valve calcifications were present
in 38 patients. A close correlation between functional class and cardiac index at
rest could be demonstrated. Early mortality was 1.5 percent; late, 3.7 percent. Late
results show 73 percent of the patients still improving, 9 percent about the same,
and 1 percent deteriorated. Calcifications or slight to moderate mitral insufficiency
in patients with predominant mitral stenosis do not preclude success of closed mitral
commissurotomy, but careful and staged dilatation is mandatory in these cases. Results
were slightly better in patients with noncalcified mitral stenosis than in those with
a calcified mitral valve. The advantage of closed mitral commissurotomy over the open
technique is a significantly lower rate of prosthetic replacement of the mitral valve.
