In twenty six consecutive patients who underwent balloon mitral valvotomy (BMV) by the transseptal double balloon technique, the mitral valve area (MVA) increased from 0.78 +/- 0.1 cm2 to 1.80 +/- 0.3 cm2, (p < 0.001). Effective balloon dilating area (EBDA) of each combination of balloons used was calculated using a standard formula. Patients were classified into 4 subgroups with approximate EBDAs of 3.3, 4.0, 4.9 and 5.7 cm2 and they had mean post-BMV MVAs of 1.28, 1.78, 1.89 and 1.98 cm2 respectively (ANOVA F = 3.32, p < 0.05). Patients were reclassified after normalisation of EBDA and post-BMV MVA to square metre of body surface area. Three subgroups with mean normalised EBDAs of 2.32, 2.96 and 3.62 cm2/m2 had mean normalised post-BMV MVAs of 0.99, 1.17 and 1.40 cm2/m2 respectively (ANOVA F = 6.85, p 0.01). A trend towards increasing mitral regurgitation with increasing balloon size was noted. Three cases of mitral regurgitation including one case of severe mitral regurgitation occurred in the subgroup of 9 patients with largest normalised EBDAs. The overall correlation between normalised EBDAs and normalised post BMV MVA was strong r = 0.67, p < 0.01). The optimal normalised EBDA for Indian patients undergoing BMV is around 3.6 cm2/m2. Balloons used should be sized accordingly. |
