Background and aim of the study: Three-dimensional (3D) transesophageal echocardiography (TEE) is useful for the quantification of mitral valve structures. The study aim was to investigate, in a quantitative manner, any differences in mitral valve anatomy among patients with mitral valve prolapse (MVP) or functional mitral regurgitation (FMR), compared to normal control subjects.

Methods: 3D-TEE was performed in 20 MVP patients, 10 FMR patients and in 15 control subjects. Analyses of the full-volume 3D mitral valve data sets were performed offline, using Q-Lab software.

Results: Distinctive patterns were identified in annular geometric changes in normal subjects compared to patients with MVP or FMR. Patients with FMR showed significant annular anterior to posterior dilatation (34.6 ± 8.3 mm versus 28.4 ± 2.9 mm, p <0.04: FMR versus control), whereas in patients with MVP dilatation in the anterolateral to posteromedial diameter was more prominent (41.0 ± 5.9 mm versus 36.6 ± 2.4 mm, p <0.03; MVP versus control).

Conclusion: 3D-TEE represents a useful method for the evaluation of mitral valve geometry.
