Abstract
Between 1956 and 1989, 5326 patients with rheumatic mitral stenosis were treated with closed mitral commissurotomy. Two-thousand one-hundred and fourteen (39.7%) were in New York Heart Association functional Class IV. The overall hospital mortality was 3.1 per cent and during the last ten years only 1.55 per cent. Five-thousand two-hundred and twenty (98.0%) patients had a satisfactory surgical result. In the remaining patients the commissurotomy was inadequate, 16(0.3%) requiring emergency valve replacement. An actuarial analysis showed a 94.0, 89.4, 85.0 and 78.3 per cent survival at six, 12, 18 and 24 years respectively without requiring a second procedure. The incidence of restenosis varied from 4.2 per cent to 11.4 per cent per 1000 patients/year between the fifth and fifteenth yeart of follow-up. Closed transventricular re-commissurotomy was carried out in 200 patients. Based on this experience we prefer and recommend closed commissurotomy as the palliative procedure of choice in rheumatic mitral stenosis.
