“…Standard echocardiographic assessment protocols include 2D echo, color Doppler imaging, and TDI. Two‐dimensional speckle tracking echocardiography (2D‐STE)–derived myocardial deformation data for the early detection of myocardial dysfunction and segmental contractility becomes a subject of great interest for clinicians 9–11 . Specifically, LS has already been proven to be a more feasible and sensitive parameter for clinical function evaluation.…”

Objective We try to investigate whether the values of longitudinal strain present differences between the left and right ventricles in long‐time follow‐ups after heart transplantation (HTx) with dynamic changes in function. Methods and Results Follow‐up transthoracic echocardiography was performed in 1‐ and 3‐month and 1‐ and 5‐year follow‐ups in 50 “healthy” HTx patients and compared with 26 control subjects. The left ventricle with preserved ejection fraction evaluated by biplane Simpson (control group [CG] vs HT; P > .05) had an obvious reduction in global (CG: −20.49 ± 2.38 vs heart transplant 1 month [HT1m]: −13.06 ± 2.86, heart transplant 3 month [HT3m]: −13.61 ± 2.61, heart transplant 1 year [HT1y]: −13.69 ± 4.56, heart transplant 5 year [HT5y]: −14.41 ± 4.54; P < .001) and horizontal segmental (basal, mid, apical) (P < .001) together with chamber segmental (apical 4‐chamber, apical 3‐chamber, apical 2‐chamber) (P < .001) average strain values. The right ventricle with reduced ventricular function measured by tissue Doppler imaging S’ and tricuspid annular plane systolic excursion had a more distinctive reduction in global (CG: −24.53 ± 4.20 vs HT1m: −12.94 ± 5.03, HT3m: −13.68 ± 4.35, HT1y: −14.95 ± 7.50, HT5y: −15.20 ± 6.15; P < .001) with segmental lateral (P < .001) strain values. There were not any significant changes between 1‐ and 3‐month follow‐ups of all the values (P > .05). But it could be seen that values increased in 1‐ and 5‐year follow‐ups compared with the baseline of 1‐ and 3‐month follow‐ups (P < .05). The global and segmental strain of the right ventricle decreased more than that of the left ventricle in all HTx groups, and the strain values were decreased in the HTx groups compared with the CG, with the global decreased change rates being 11%, 10%, 6%, and 8%, respectively. Conclusions The strain values decreased after HTx and almost remained stable in the long‐time follow‐ups. Compared with the CG in both ventricles, they were with preserved or reduced functions. In addition, the deformation values of the right ventricle decreased more than those of the left.

“…[7][8][9] Two-dimensional STI-derived myocardial deformation data for early detection of myocardial function and segmental contractility recommend the new noninvasive tool which recently have become a subject of great interest for clinicians. [10][11][12] Becker et al 3 reported that using peak systolic radial strain enabled detection of hypokinesis or akinesis with a sensitivity of 83.5% and a specificity of 83.5%, while using RS peak-sys analysis enabled detection of akinesis versus hypokinesis with a sensitivity of 82.7% and a specificity of 94.5% in 64 patients. And Choi et al 13 found that LS peak-sys of LV from 2D STI image might be useful for screening of severe coronary artery disease (CAD) before the regional WMA in 180 patients.…”

“…5−7 Prior studies have examined the reproducibility of echocardiography-based LV strain measures in predominantly small-sized or referral samples. 8−11 Accordingly, comprehensive data regarding the reproducibility of LV strain measures in a community-based setting are lacking. Therefore, the present study was designed to evaluate the reproducibility of speckle-tracking based LV strain measures in the Offspring cohort of the Framingham Heart Study.…”

Background The reproducibility of echocardiographic measurements of myocardial strain, performed in a community-based setting, has not been reported previously. Methods We examined the reproducibility of left ventricular (LV) strain measurements in two samples of 20 participants each from the Offspring cohort of the Framingham Heart Study (mean age 63±9 years, 59% women). Two-dimensional speckle tracking-based measurements of global peak LV strain in systole were performed in the apical 4-chamber, apical 2-chamber, and mid-ventricular parasternal short-axis views. Results Inter-observer intra-class correlation coefficients (ICC) were ≥0.84 for all global strain measurements, with average coefficients of variation (CV) of ≤4% for global longitudinal and circumferential strain, and <8% for global transverse and radial strain. For LV strain measurements performed in each of the 3 views, intra-observer ICCs were ≥0.91 among time points spanning a total 8-month period. The average CVs were <6% for global longitudinal and circumferential strain, and <9% for global transverse and radial strain. Inter- and intra-observer reproducibility findings were similar in analyses adjusting for frame rate. Conclusions We observed excellent reproducibility of global longitudinal and circumferential strain measurements and very good reproducibility of global transverse and radial strain measurements. Taken together, our findings demonstrate the reproducibility of performing echocardiographic strain measurements in a large, epidemiologic community-based setting.
