“…The important steps in performing PTMC are atrial septal puncture and crossing the mitral valve [2] , [3] . This procedure is cost effective, less invasive and free from complications related to surgery and very rarely leads to pericardial tamponade [4] , [5] . The assessment of the mitral valve morphology is very important because the success of PTMC is grater in patients with thin, pliable valve leaflets and little subvalvular disease [6] , [7] .…”

IntroductionPercutaneous 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.MethodsIt 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.ResultsPTMC 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.ConclusionsMV 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.

“…The most important steps in performing PMBC are atrial septal puncture and crossing the mitral valve [13][14] which are a fundamental knowledge to a technical success. The procedure is cost effective, less invasive and free from complications related to surgery and very rarely leads to pericardial tamponade [15][16]. Such intervention however, has not been done in the country and our cardiac center took the initiatives and performed PMBCs for patients referred from the entire country with heterogeneous presentations of severe MS.…”

Percutaneous mitral balloon commissurotomy (PMBC) is the treatment of choice for rheumatic mitral stenosis with favorable anatomy and prevents complications inherent to a surgical procedure, while maintaining effectiveness. In view of this, we examined the immediate outcome and its predictors of patients undergoing PMBC in our Cardiac Center and availed evidence based information for future use of the treatment in Ethiopia. A retrospective data analysis of 330 patients with symptomatic severe mitral stenosis treated with PMBC using Inoue balloon in the cardiac center Ethiopia from 2014 to 2018 were assessed for their clinical outcome for those who presented for the first time in our cardiac center, Addis Ababa. Demographic, clinical, echocardiographic and hemodynamic data of all patients with symptomatic severe mitral stenosis were collected and analyzed. Of the 330 PMBC performed during the 5 years in the center, the majority had successful procedure (97.88%) and optimal result (92.42%). Twenty four (7.2%) had complications of which 7 (2.1%) had failed procedure and 9 (2.7%) marked mitral regurgitation. Atrial fibrillation was observed in 67 (20.3%). The mean mitral valve score (MVS) was 7.3± 1.35 ranged from 4 to 13. A significant association of immediate outcome was observed with atrial fibrillation (AOR=4.41; 95% CI=1.51 to 12.89) and high mitral valve total Wilkins score (AOR=0.25; 95% CI 0.09 to 0.70). The major predictors identified for poor outcome are atrial fibrillation and MVS. Percutaneous mitral balloon commissurotomy is a safe procedure with excellent immediate results signifying that it is a treatment of choice for heterogeneous group of patients with rheumatic mitral stenosis.
