Immediate, intermediate and long term clinical outcomes of percutaneous transvenous mitral commissurotomy
Introduction: Percutaneous transvenous mitral commissurotomy (PTMC) is one of the nonsurgical commissurotomy in patients with hemodynamically significant mitral stenosis. The aim of the present study is to assess the immediate, intermediate and long term outcomes of PTMC in relation to initial mitra...

| description | Introduction: Percutaneous transvenous mitral commissurotomy (PTMC) is one of the nonsurgical commissurotomy in patients with hemodynamically significant mitral stenosis. The aim of the present study is to assess the immediate, intermediate and long term outcomes of PTMC in relation to initial mitral valve score and to assess its impact on mitral valve area (MVA), clinical and hemodynamic parameters.
Methods: It is a retrospective study on a total of 303 patients who underwent successful PTMC between 1994 and 2001, were called back and their preprocedural, immediate post and follow-up (4, 7 and 10 year.) data were analyzed. Echo was performed in patients before and after PTMC. The patients were divided into two groups, group-I with Wilkins score of ≤8 and group-II with Wilkins score between 8 and 12.
Results: PTMC patients who have completed 4, 7 and 10 years of follow up revealed the mitral valve area, mean transmitral gradient and pulmonary artery pressures to be significantly different in both group-I and group-II. At all follow-up periods group-II showed higher restenosis than group-I, but its distribution between the groups was not statistically significant (χ2 = 0.029; p = 0.986). Furthermore, losses of the MVA during different periods of follow-up revealed a gradual increase in attrition.
Conclusions: MV score, Mitral valve area, mitral gradient and pulmonary artery pressures appeared to influence the outcome of PTMC. A clear-cut prospective assessment of individual components of the mitral valve apparatus using 3-D echocardiographic images may provide a more precise prediction of the PTMC outcome based on its morphological abnormalities. |
