“…Strain and strain rate echocardiography are superior to tissue Doppler echocardiography in the evaluation of regional myocardial function because they are not affected by the translation and stretching of neighbouring myocardial segments 16. 2D strain and strain rate echocardiography also can assess different clinical conditions, such as hypertension, obesity, post exercise, Marfan syndrome, healthy children and infants 1518…”

SummaryObjectiveThis study aimed to evaluate strain and strain rate echocardiography in children with Wilson’s disease to detect early cardiac dysfunction.MethodsIn this study, 21 patients with Wilson’s disease and a control group of 20 age- and gender-matched healthy children were included. All the patients and the control group were evaluated with two-dimensional (2D) and colour-coded conventional transthoracic echocardiography by the same paediatric cardiologist using the same echocardiography machine (Vivid E9, GE Healthcare, Norway) in standard precordial positions, according to the American Society of Echocardiography recommendations. 2D strain and strain rate echocardiography were performed after the ECG probes of the echocardiography machine were adjusted for ECG monitoring. Longitudinal, transverse and radial strain, and strain rate were assessed from six basal and six mid-ventricular segments of the left ventricle, as recommended by the American Society of Echocardiography.ResultsLeft ventricular wall thickness, systolic and diastolic diameters, left ventricular diameters normalised to body surface area, end-systolic and end-diastolic volumes, cardiac output and cardiac index values were within normal limits and statistically similar in the patient and control groups (p < 0.05).Global strain and strain rate: the patient group had a statistically significant lower peak A longitudinal velocity of the left basal point and peak E longitudinal velocity of the left basal (VAbasR) point, and higher global peak A longitudinal/circumferential strain rate (GSRa) compared to the corresponding values of the control group (p < 0.05).Radial strain and strain rate: end-systolic rotation [ROT (ES)] was statistically significantly lower in the patient group (p < 0.05). Longitudinal strain and strain rate: end-systolic longitudinal strain [SLSC (ES)] and positive peak transverse strain (STSR peak P) were statistically significantly lower in the patient group (p < 0.05).Segmental analysis showed that rotational strain measurement of the anterior and lateral segments of the patient group were statistically significantly lower than the corresponding values of the control group (p < 0.05). Segmental analysis showed statistically significantly lower values of end-systolic longitudinal strain [STSR (ES)] of the basal lateral (p < 0.05) and end-systolic longitudinal strain [SLSC (ES)] of the basal septal segment (p < 0.05) in the patient group.End-systolic longitudinal strain [SLSC (ES)] and positive peak transverse strain (STSR peak P) were statistically significantly lower in the patient group (p < 0.05). Segmental analysis showed statistically significantly lower values of endsystolic longitudinal strain [SLSC (ES)] of the mid-anterior and basal anterior segments (p < 0.05), end-systolic longitudinal strain [STSR (ES)] measurements of the posterior and mid-posterior segments, end-systolic longitudinal displacement [DLDC (ES)] of the basal posterior, mid-posterior and mid-antero-septal segments in the patient group.Conclusion...

“…In 2D STE, prior studies have demonstrated the increased sensitivity in detecting subclinical cardiac involvement in conditions such as diabetes, hypertension, amyloidosis, chemotherapy, athlete's heart, hypertrophic cardiomyopathy, aortic regurgitation, acute coronary ischemia, inducible coronary ischemia, differentiation of transmural from subendocardial infarction, and viable from nonviable myocardium. 10,13 In patients with coronary disease, hypertension, amyloidosis, and cardiomyopathies, there is abnormal longitudinal strain well before twist mechanics are affected. In patients with athlete's heart, longitudinal strain is preserved, enabling differentiation of thick walls from hypertrophic cardiomyopathy in young athletes.…”

Speckle tracking echocardiography (STE) is an emerging tool to characterize and quantify myocardial segmental and rotational mechanics. This literature review is aimed at clinical and academic cardiologists to provide: (1) a conceptual framework of STE to initiate understanding of myocardial mechanics; (2) evidence that three-dimensional (3D) STE overcomes the problems of time-consuming data acquisition and postprocessing seen with two-dimensional STE; and (3) illustrative clinical cases with analysis of myocardial mechanics via 3D STE to show the incremental value of strain in clinical decision making.

“…In general, with increasing width of the tracking area higher values of PSS, PSSR, PSI and lower values of PLD and PTD were determined in both cohorts (Figs. [3][4][5]. Thus, global PSS was significantly influenced by the width of the tracking area.…”

“…1 Wall-motion analysis and deformation imaging by 2D speckle tracking enables further possibilities for the evaluation of left ventricular systolic function or myocardial function, respectively. 2,3 Using 2D speckle tracking specific grayscale patterns of the myocardium are detected from frame to frame over a distinctive period of time. 2D speckle tracking requires frame rates of 40-80 bps to get a sufficiently high lateral resolution for most accurate tracking of the myocardium.…”

The Impact of the Width of the Tracking Area on Speckle Tracking Parameters—Methodological Aspects of Deformation Imaging

The strain values determined by 2D speckle tracking are significantly influenced by the tracking area width. The tracking of the subendocardial layers only results in lower global strain values than tracking the complete ventricular wall using the medium or wide tracking area widths. The tracking quality in the far field is worse if the tracking area is too wide. The present data show that standard and reference values of deformation imaging should include detailed information about the position and the width of the tracking area.
