“…The incidence of mitral regurgitation was similar to previous reports in adults [1,[13][14][15] as well as in juvenile MS [3,6,7,16]. Two children (4.4%) required mitral valve replacement.…”

“…Rheumatic mitral stenosis in the developing countries often afflicts the younger patients (juvenile mitral stenosis) and is more severe [5]. However, the reports of PTMC in juvenile mitral stenosis mostly pertains to the adolescent patients [6,7]. Accordingly, we report our experience of PTMC in children less than 12 years of age using Inoue balloon.…”

“…As in previous studies [6,7,9,10,19,, the present study also has shown that hemodynamic results of PTMC are related to the morphology of the diseased mitral valve. In group 1 patients with pliable noncalcified valves, optimal hemodynamic results were comparable to other series of similar valve morphology [10,11,17,26,34,35,39]. The hemodynamic benefit was mirrored in an immediate clinical improvement.…”

“…Despite this crucial relationship between appropriate balloon sizing and a successful uncomplicated PTMC outcome, there is still a lack of consensus in selecting the appropriate balloon size irrespective of technique. This has resulted in elaborate or empirical balloon sizing formulae for either single-balloon [ 10, 17,23,24,26,31,32,44] or double-balloon techniques [5,7,11,15], using the mitral annulus diameter [44], body surface area [23,3 1,321, weight [lo], height [24,26,32], or trigonometry incorporating the balloon radius [ 1 1,151 as the principal variable.…”

This study was carried out to examine whether the previously determined balloon sizing method based on patient height was valid for percutaneous transvenous mitral commissurotomy using the current second-generation Inoue balloon catheter. The study consisted of 70 patients with pliable noncalcified mitral valves (group 1) and 85 patients with calcified mitral valves and/or severe subvalvular lesions (group 2). The mitral valve area was increased more in group 1 than in group 2 (1.0 +/- 0.3 to 1.9 +/- 0.5 cm2 versus 1.0 +/- 0.3 to 1.6 +/- 0.5 cm2, P = 0.002). Using the stepwise dilatation technique, none of the group 1 patients developed severe mitral regurgitation. Severe mitral regurgitation occurred in 4 patients (4.7%) in group 2. In conclusion, a simple balloon sizing method based on body height for selection of an appropriate-sized balloon catheter, as well as an initial inflated balloon diameter for the stepwise dilatation technique is useful for optimal acute outcomes in mitral commissurotomy.

Despite the established role of percutaneous balloon mitral valvuloplasty (BMV) in the treatment of mitral stenosis, major controversial issues in the realm of BMV persist. With increased operator experience, BMV has now been extended to include various controversial scenarios, such as mild mitral stenosis, adverse valve morphologies, and high-risk patients with concomitant anatomic distortions which are technically demanding. In skilled hands, however, BMV has yielded a favorable outcome in these settings. Furthermore, the debate on whether the Inoue or the double-balloon approach is superior continues. Studies to date have shown equal efficacy of the two BMV methods in terms of valve enlargement although the Inoue approach is clearly simpler to execute and may potentially be associated with a lower risk of creating severe mitral regurgitation. Last, because of the lack of consensus on optimal balloon sizing for BMV, perhaps the best method to adopt at this stage is one that is simple and safe to apply across a broad spectrum of valve anatomy.
