Abstract:
To determine the long-term results after PMV, the incidence of restenosis and analysis the factors predicting restenosis, 108 patients were studied at pre-, post-PMV, after 3 months and 1 year (13+/-4 months) with echocardiography. 1) Restenosis was demonstrated in 25 of 108 patients(23%) at 1 year follow-up. 2) Descriminant analysis showed echocardiographic score and mitral valve area before PMV as predictors of restenosis. 3) There were significant decreament of mitral valve area from 1.8+/-0.4cm2 (after PMV) to 1.5+/-0.3 cm2 at 3 months follow-up and further stenosis (1.2+/-0.3 cm2) at long-term follow-up in group with restenosis. In contrast, in group without restenosis, mitral valve area after PMV was 1.8+/-0.3cm2, aat 3 months follow-up was 1.8+/-0.3cm2 and at long term follow-up was 1.8+/-0.4cm2. 4) There was higher restenosis rate in group with Inoue balloon (47%) than group with double balloon (18%) despite of large EBDA/BSA.
