Assessment of Mitral Annular Velocities by Speckle Tracking Echocardiography versus Tissue Doppler Imaging: Validation, Feasibility, and Reproducibility

Tissue velocities can be accurately determined by STE in a moving phantom and are angle independent, in contrast with TDI measurements. Furthermore, STE is a feasible and better reproducible method for the assessment of mitral annular velocities in a clinical setting.
