Does sonomicrometry array localization provide reproducible three-dimensional imaging of the mitral valve and left ventricle in an experimental sheep model?
Sonomicrometry array localization is a highly reproducible method for tracking the 3D geometry and dynamics of the mitral valve and left ventricle in experimental animal models.
Gorman et al. (1996) studied Mitral valve and left ventricle dynamics (n=8). Sonomicrometry array localization was evaluated on Reproducibility of derived chord lengths and three-dimensional coordinates. Sonomicrometry array localization in sheep is highly reproducible, with an average distance measurement error of 1.6% and 3D coordinate error of 2.2 mm, suitable for serial observations.
