2D speckle-tracking echocardiography offers a method to measure myocardial deformation through the heart cycle, overcoming some limitations of standard LVEF calculation.
T wo-dimensional (2D) speckle-tracking echocardiogra- phy has, in recent years, emerged as a new method for assessing left ventricular systolic and diastolic function.1 The technique measures the movement of nonrandom coherent speckles in 2D echocardiographic images.Speckle-tracking measures myocardial deformation through the heart cycle rather than volumetric changes between end-diastole and endsystole, the standard method for calculating left ventricular ejection fraction (LVEF), which is dependent on image quality, the ability to accurately trace the endocardial border, and geometric assumptions required to estimate volumes from a 2D image. 2
