 note = {Percutameous transvenous mitral commissurotomy (PTMC) using Inoue balloon catheter was attempted in 61 patients with symptomatic rheumatic mitral stenosis. There were 49 women and 12 men (mean age 50±11 years). PTMC was performed using a stepwise dilatation technique. After PTMC the mean mitral valve pressure gradient decreased from 11.2±5.6 mmHg to 5.6±2.8 mmHg (p<0.0001) and the mitral valve area (Gorlin formula) increased from 1.1±0.3 cm^2 to 1.8±0.5 cm^2 (p<0.0001). Mitral regurgitation increased by one grade in 15 patients (24.6 %), two grades in 5 (8.2 %) and three grades in 1 (1.6 %). Fifty-nine patients (96.7 %) were symptomatically improved. No patients required cardiac surgery or had major complications. At mean follow-up of 7.4 months the mean mitral valve area was 1.6±0.5 cm^2 (Gorlin formula). We concluded that PTMC, using the Inoue balloon, is safe and effective in the treatment of mitral stenosis and a stepwise dilatation technique is useful for preventing the creation of severe mitral regurgitation.},
