    Abstract

    Aims. Transoesophageal echocardiography (TOE) plays a vital role in the assessment of mitral valve morphology. However, the accuracy of TOE may be limited by inadequate recognition of all segments. We aimed to evaluate the role of three-dimensional (3D) echocardiography in this respect. Methods and results. Seventy-five patients were studied prior to mitral valve repair surgery. A scoring protocol was devised for recognition of the eight Carpentier segments (0 = inadequate for analysis, 1 = adequate, 2 = good). Using surgical findings as the gold standard, TOE and 3D were compared for adequate recognition scores and accurate detection of functional morphology. Adequate recognition was more frequently obtained with 3D imaging (97% of segments by 3D c.f. 90% by TOE; p = 0.000). The major difference was seen at the commissures (adequate scores in 143/150 commissures by 3D c.f. 90/150 by TOE; p
