BACKGROUND: Mitral valve (MV) repair is the procedure of choice for @entity1 with @entity179 ( @entity179 ) with severe @entity339 . The aim of this study was to identify specific quantitative MV parameters from preoperative three-dimensional (3D) transesophageal echocardiography that are associated with the length of the mitral annuloplasty band implanted and the performance of leaflet resection in @entity1 with @entity179 undergoing MV repair. METHODS: Ninety-four @entity1 (mean age, 60      11  years; 68% @entity1 ) referred for MV surgery with adequate-quality preoperative 3D transesophageal echocardiographic studies were retrospectively identified. Parametric maps of the MV were generated using semiautomated MV modeling software. Annular and valvular parameters were measured and indexed to body surface area. The implanted annuloplasty band size and leaflet resection were determined on the basis of surgical reports. RESULTS: Three-dimensional annular circumference correlated best (r  =  0.74) with the implanted annuloplasty band length and remained an independent predictor on multivariate linear regression analysis. A third of our cohort (n  =  33) had posterior leaflet resection. On receiver operating characteristic curve analysis, P2 segment length >=  20  mm (area under the curve, 0.86; sensitivity, 88%; specificity, 74%) and P2 leaflet area >=  3.4  cm(2) (area under the curve, 0.84; sensitivity, 85%; specificity, 74%) best discriminated the need for leaflet resection. CONCLUSIONS: In @entity179 , quantitative 3D annular circumference obtained from semiautomatically generated parametric maps of the MV from 3D transesophageal echocardiographic data was associated with the surgically implanted annuloplasty band length, while P2 leaflet length >=  20  mm and area >=  3.4  cm(2) were associated with the performance of leaflet resection. These parameters should be further investigated for preoperative planning in @entity1 with @entity179 undergoing MV repair.
