Speckle tracking echocardiography (STE) was popularized in the first decade of this century. Analysis of cardiac mechanics has been the focus of ultrasonics, and the breakthrough came with STE. Beyond analysis solely of left ventricular ejection fraction, STE allows the assessment of various pathophysiologies, including myocardial layer-specific myocardial function, twist and rotation, and dyssynchrony. Recent developments in the technology have resulted in commercially available 3-dimensional (D)-STE systems. Through experimental studies and clinical investigations, the reliability and feasibility of 3D-STE-derived data have been validated, and the advantages of 3D-STE over 2D-STE have been revealed. In addition, because of the 3D nature of the technology, 3D-STE provides novel deformation parameters (ie, 3D-strain and area change ratio) that have the potential for more accurate assessment of overall and regional myocardial function. Recently, various preliminary studies using 3D-STE have reported on myocardial characteristics, novel mechanics in the left ventricle, prediction of therapeutic effects, observations of cardiac function through interventions, and challenges for left atrial and right ventricular functions. In this review, we focus on the features of the methodology, validation, and clinical application of 3D-ST.

Cardiac function analysis is the main focus of echocardiography. Left ventricular ejection fraction (LVEF) has been the clinical standard, however, LVEF is not enough to investigate myocardial function. For the last decade, speckle tracking echocardiography (STE) has been the novel clinical tool for regional and global myocardial function analysis. However, 2-dimensional imaging methods have limitations in assessing 3-dimensional (3D) cardiac motion. In contrast, 3D echocardiography also has been widely used, in particular, to measure LV volume measurements and assess valvular diseases. Joining the technology bandwagon, 3D-STE was introduced in 2008. Experimental studies and clinical investigations revealed the reliability and feasibility of 3D-STE-derived data. In addition, 3D-STE provides a novel deformation parameter, area change ratio, which have the potential for more accurate assessment of overall and regional myocardial function. In this review, we introduced the features of the methodology, validation, and clinical application of 3D-STE based on our experiences for 7 years.

“…It has already been used for assessing the accuracy of motion-derived measures such as twist [22] or surface area changes [23]. Segmental strain values obtained by tracking and sonomicrometry were compared by Seo et al [24] and Heyde et al [25]. For an extensive review of existing 3D strain techniques in echocardiography, the reader can refer to the recent review of Jasaityte et al [26].…”
