“…XStrain STE has been used to evaluate subclinical myocardial damage (Figure 10) in patients with left ventricular hypertrophy and to characterize its various causes [30][31][32][33]. Badran et al [33] have shown that right atrial (RA) mechanics entirely follows right ventricular (RV) and LV function, as well as disease severity.…”

Because of its excellent ability to non-invasively assess left ventricular (LV) systolic function, two-dimensional speckle tracking echocardiography (STE) is increasingly being used in echocardiographic laboratories worldwide. Two-dimensional STE is the most sought-after method to evaluate LV strain, rotation, twist and torsion. Two dimensional, three-dimensional and four-dimensional (4D) deformation estimation by STE has several intrinsic limitations. For better appraisal of LV contractile properties, a recently introduced updated version of 4D XStrain STE has been used to analyse the various complex multidimensional LV mechanics. This novel technology is a reliable, economical and simple tool for estimating regional and global myocardial function. Furthermore, 4D XStrain STE can accurately quantify the 4D LV ejection-fraction, LV volume and sphericity index. However, this technology has not been extensively implemented, and its assessment remains limited primarily to research applications. Hence, we aim to promote this innovative technology by comprehensively addressing its technique, advantages and limitations, so that it can be better applied in cardiovascular disease.

“…GLS of LV was at lower extremes of normality and produced a marked gradient from basal to mid apical segments, which was not evident in healthy controls  HYPERTROPHIC CARDIOMYOPATHY: STE has been reported to be used for detecting subclinical myocardial changes in LV hypertrophy (Figure 10), as well as for distinguishing the different causes of LV hypertrophy. [30][31][32][33] Figure 10: LV longitudinal strain curves in apical 3CH of Hypertrophic Cardiomyopathy (A) Latent obstruction showed lower strain values and increased electromechanical delay and (B) Non Obstructive demonstrated higher strain values and lower electromechanical delay  DILATED CARDIOMYOPATHY: This pathology is associated with the reduction of strains in all 3 directions (Figure 11) and STE can therefore be widely used to detect and stage it.

Strain based imaging techniques, particularly speckle tracking echocardiography (STE) have been shown to have clinical utility in a variety of clinical settings. Currently, STE is being embraced and increasingly adopted in numerous echocardiographic laboratories worldwide. In context with contemporary non invasive cardiovascular procedures, 2Dimensional STE is most sought-after method to evaluate LV strain, rotation, twist and torsion. Two dimensional (2D), three dimensional (3D) and 4Dimensional (4D) deformation assessment by STE is inherently associated with certain limitations. For better appraisal of LV contractile properties recently introduced updated version of 4D XStrain STE has been employed to analyse the various complex multidimensional LV mechanics. This novel technology is a reliable, affordable and a simple tool for estimation of regional and global myocardial function. Furthermore, 4D XStrain STE can accurately quantify the 4D LV ejection-fraction, end-diastolic and end-systolic volumes and sphericity index (SI). However, this distinctive technology has not been widely adopted and its assessment is still limited to research applications. Hence we aimed to familiarize this innovative technology by comprehensively addressing its technique, advantages and limitations, with the intent that it may serve a more meaningful purpose in the current volatile scenario of cardio-vascular disease. Keywords: 4Dimensional XStrain Echocardiography, LV strain, LV rotation, LVtwist, LV untwist, LV torsion.
