“…Although numerous studies have documented favorable immediate and intermediate follow-up results [1,2,3,4,5,6,7,8,9,10,11,12], long-term echocardiographic follow-up studies of MBV are scarce [13,14,15,16,17,18]. The purpose of this study was to report the long-term (up to 18 years) clinical and echocardiographic results of 531 consecutive patients who underwent successful MBV at a single institution.…”

Objectives: The study aim was to assess the long-term results (up to 18 years) of mitral balloon valvuloplasty (MBV) and to identify predictors of restenosis and event-free survival. Methods: The immediate and long-term results for 531 consecutive patients (mean age 31 ± 11 years) who underwent successful MBV and were followed up for a mean of 8.5 ± 4.8 years (range: 1.5–18 years) are reported. Results: The mitral valve area (MVA) increased from 0.92 ± 0.17 to 1.95 ± 0.29 cm² (p < 0.0001). Restenosis was 31 and 19% in patients with mitral echocardiographic score (MES) ≤8. Actuarial freedom from restenosis at 10, 15 and 18 years was 77 ± 2, 46 ± 3 and 18 ± 4% and 86 ± 2, 62 ± 4 and 31 ± 7% for MES ≤8, respectively (p < 0.001). Event-free survival (death, redo MBV, mitral valve replacement, NYHA class III or IV) at 10, 15 and 18 years was 88 ± 1, 53 ± 4, and 21 ± 5% and 93 ± 2, 65 ± 5 and 38 ± 8% for MES ≤8, respectively (p < 0.001). Multivariable Cox regression analysis identified MES >8 (p < 0.0001) and previous surgery (p = 0.043) as predictors of restenosis, and MES >8 (p < 0.0001) and baseline atrial fibrillation (p = 0.03) as predictors of combined events. Conclusion: MBV provides excellent long-term results. The baseline clinical and MES characteristics are predictors of outcome.

“…It is effective in reducing mitral valve obstruction when evaluated acutely or on a long-term basis [l-381. However, not uncommonly it leads to the appearance or an increase in the severity of mitral regurgitation [4][5][6][7][8][9][10][11][12]14,15,[19][20][21][22][23][24][25][26][27][28][29]. Although the mitral regurgitation in most cases is mild and of no clinical consequence, in a small number of patients severe mitral regurgitation results, requiring surgical intervention [9,10,12,15,23,29,43].…”

“…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.
