%X percutaneous mitral commissurotomy (pmc) has emerged as an effective nonsurgical technique for the treatment of patients with symptomatic mitral stenosis. this report highlights the immediate and long-term follow-up results of this procedure in an unselected cohort of patients with rheumatic mitral stenosis from a single center. pmc with inoue balloon was performed in 70 patients in a 2-year period (1993-1994). age of patients ranged from 18 to 67 years (mean 38 ¡À 11). atrial fibrillation was present in 18 (30%) patients. a detailed clinical and echocardiographic (two-dimensional, continuous-wave doppler and color-flow imaging) assessment was done at follow-up. the procedure was technically successful in 61 (85%) patients with an increase in mitral valve area (mva) from 0.96 ¡À 0.2 to 1.7 ¡À 0.28 cm2 (p < .001) and a reduction in mean trans-mitral gradient from 14.3 ¡À 4.8 to 6.0 ¡À 2.8 mmhg (p < .01). mitral regurgitation appeared or worsened in 25 (30%) patients, of which 3 (4%) developed severe mitral regurgitation. urgent mitral valve replacement was performed in these 3 patients. data of 52 patients followed over a period of 105 ¡À 10 months revealed mva of 1.4 ¡À 0.4 cm. elective mitral valve replacement was done in 14 (23%) patients. mitral restenosis diagnosed with echocardiography was seen in 24 (50%) patients, of which 14 were having recurrence of class iii or more symptoms and were treated with surgery. thus, percutaneous mitral commissurotomy is an effective and safe procedure and over 2/3 of the patients were event-free at the end of follow-up. the benefits are sustained in most of these patients on long-term follow-up.
