    Abstract:
    OBJECTIVES: To compare the immediate and long term results of percutaneous mitral valvotomy using metallic commissurotome and Inoue balloon in juvenile mitral stenosis. BACKGROUND: Inoue balloon technique for mitral commissurotomy (IBMC) is well established and carried out worldwide in the treatment of juvenile mitral stenosis. Percutaneous mitral metallic commissurotomy (PMMC) is reported to be a cheaper and effective alternative to balloon mitral commissurotomy. METHODS: Thirty-three patients aged less than 20 years, who underwent PMMC, were compared with 33 age and sex matched control patients who underwent IBMC. Success of valvotomy, procedure related complications, and follow-up events of the two techniques were compared. RESULTS: Basal echocardiographic and hemodynamic data were similar in both groups. Procedural success was similar in both groups, 31/33. Complications like cardiac tamponade and mitral regurgitation (requiring or not requiring mitral valve replacement) were similar in both groups. On follow-up of more than 3 years, both groups had comparable hemodynamic parameters and restenosis rates. CONCLUSIONS: Both IBMC and PMMC are successful in providing relief from severe juvenile mitral stenosis in terms of gain in valve area and reduction in transmitral gradient. Both techniques have similar procedural success and complication rates. The long term follow-up results are comparable at follow-up of more than 3 years.
