AbstractObjectivesTo evaluate 24-segment fractional shortening (FS) of the fetal heart using FetalHQ by speckle-tracking regarding reproducibility and the change with advancing gestation.MethodsEighty-one pregnant women at 18–21 + 6 and 28–31 + 6 weeks of gestation were studied using FetalHQ with the speckle-tracking technique to calculate 24-segment FS of left and right ventricles. Intra- and inter-class correlation coefficients and intra- and inter-observer agreements of measurements for FS were assessed in each segment.ResultsWith respect to intra-observer reproducibility, all FS values showed correlations between 0.575 and 0.862 for the left ventricle, with good intra-observer agreements except for left ventricular segments 14–24. Right ventricular FS values showed correlations between 0.334 and 0.685, with good intra-observer agreements. With respect to inter-observer reproducibility, all FS values showed correlations between 0.491 and 0.801 for the left ventricle, with good intra-observer agreements except for left ventricular segments 16–22. Right ventricular FS values showed correlations between 0.375 and 0.575, with good inter-observer agreements. There were significant differences in the mean FS values in the basal segment (segments 1–5) of the left ventricle between 18 and 21 + 6 and 28–31 + 6 weeks of gestation (p<0.05), whereas there were significant differences in all mean FS values in the right ventricle between both gestational ages (p<0.05).ConclusionsThese results suggest that the reproducibility of the 24-segment FS of the fetal heart using FetalHQ is fair. However, there may be significant differences in FS values with advancing gestational age, especially for the right ventricle.

Introduction: The aim of the study was to establish normal reference values obtained by fetal speckle tracking analysis of the fetal heart between 17-24 weeks of gestation among Thai fetuses and compare the nomograms with previous studies. Methods: The 4-chamber view of the fetal heart in 79 normal fetuses was analyzed by speckle tracking analysis to determine the best-fit regression model. The 95% reference intervals and Z-score equations of fetal cardiac parameters were computed. Results: The end-diastolic length, width, area, and circumference of the 4-chamber view (4CV) as well as the ventricular end-diastolic length, 24-segment widths, and area were all increased as a function of gestational age (GA) and 5 fetal biometric parameters. In contrast, the global sphericity index (SI), 24-segment SI, and right ventricle/left ventricle width and area ratios did not change with GA or fetal biometric measurements. There were few differences in Z-score reference ranges of fetal cardiac measurements between the current study and previous studies conducted in different patient populations. Conclusion: Our study provided z-score and corresponding centile calculators, 5th and 95th centile reference tables, and corresponding graphs for evaluating the size and shape of the 4CV and the right and left ventricles using 6 independent variables between 17 and 24 weeks of gestation. These results provide normal reference ranges for future studies of fetuses with pathologies that may alter the size and shape of the 4-chamber view and ventricles.

Abstract The aim of this study was to assess the cardiac function in fetuses of mothers with gestational diabetes mellitus (GDM) by using fetalHQ, a quantitative analysis software for the assessment of fetal cardiac function based on speckle tracking echocardiography. In this prospective cross-sectional study, 49 fetuses exposed to GDM and 50 normal fetuses were enrolled and fetal echocardiography were performed and analyzed. In the GDM group, left ventricular (24 ± 4 vs. 28 ± 4, p < 0.001) and right ventricular global longitudinal strain (23 ± 4 vs. 26 ± 4, p = 0.002) and right ventricular free wall strain (26 ± 6 vs. 29 ± 5, p = 0.006) were significantly lower compared with the control group, whereas there was no significant difference in global spherical index (1.2 ± 0.1 vs. 1.2 ± 0.1, p = 0.425). Additionally, 24-segment transverse fraction shortening of the right ventricle was more impaired than the left and the segments with reduced fraction shortening were mainly located in the mid and apical sections of the right ventricle, and mid section of the left ventricle. In conclusion, fetuses exposed to GDM may have cardiac dysfunction before the onset of cardiac morphologic abnormalities, and the right ventricle is more vulnerable than the left during fetal development.

Septal Motion

Abnormal early septal motion observed in patients with left bundle brunch block (LBBB) has been explained as a difference in right-to-left ventricular pressure. The interventricular septum was thought to be displaced passively into the LV because the right ventricle contracts prior to the LV and the right ventricular pressure exceeds the LV pressure during early systolic phase. Assuming that this theory is right, the interventricular septal wall would be stretched and shown positive strain value in circumferential and longitudinal directions during early systolic phase. We investigated the mechanism of the early septal motion with LBBB using speckle tracking imaging (STI). Methods: Systolic septal motion on the middle LV portion level was analyzed in 44 patients with complete LBBB (mean QRS duration 166 ± 35 ms) using M-mode echocardiography and speckle tracking imaging (STI). Time from onset of QRS configuration to peak circumferential strain and longitudinal strain were measured in parasternal short axis and apical views by STI. Furthermore, 20 healthy individuals (mean QRS duration 84 ± 6 ms) were also analyzed. Changes in LV pressure and septal strain were simultaneously measured to evaluate the relationship between them in 6 patients with LBBB. Results: Septal displacement into the LV was early and abrupt on M-mode echocardiograms from all patients with LBBB. During this displacement, the STI of the interventricular septum of all patients showed negative strain in both the circumferential and longitudinal directions. Furthermore, early septal displacement almost coincided with peak negative strain. Time to peak septal strain in LBBB patients was significantly shorter than in normal controls in the circumferential (296 ± 80 vs. 356 ± 30 ms; p < 0.05) and longitudinal (317 ± 104 vs. 369 ± 17 ms; p < 0.05) directions. The peak of septal negative strain was followed by an increase in LV pressure in all patients. Conclusion: Early motion of the interventricular septum is provoked by its active contraction in LBBB. The septal contraction starts very early and almost isotonically toward a very low load. However, further shortening is suppressed by a subsequently increased load of pressure elevation due to the contraction of other LV segments.

Background The right ventricle (RV) has an essential function in cardiovascular physiology and pathology. Currently, it is gaining an increasing interest given its recognized role in many cardiovascular conditions. However, echocardiographic assessment of the RV in daily practice is frequently based on qualitative estimation, and it has been regarded as a neglected chamber. Objective We sought to review and discuss the appropriate approach and latest methods of assessment of the RV by echocardiography. Methods A MEDLINE/Pubmed search was performed, and 55 relevant articles were selected; articles addressing right ventricular assessment by echocardiography, along with the latest recommendations, have been reviewed and discussed. Results A RV diameter >42 mm at the base and >35 mm at the mid-cavitary level indicates right ventricular dilatation; a longitudinal myocardial velocity (S′) <9.5 mm/s, a tricuspid annular plane systolic excursion <17 mm, and a fractional area change <35% are indices of right ventricular systolic dysfunction. A right ventricular ejection fraction of >45% and an absolute value of global longitudinal strain of >21% reflect normal systolic function. The significance of dp/dt, the right myocardial performance index and isovolumic myocardial acceleration, is also discussed along with the parameters of right ventricular diastolic function. The use of novel echocardiographic approaches, such as three-dimensional echo and speckle tracking imaging, allows practitioners to overcome the challenges encountered with conventional echocardiography. Conclusion Accurate assessment of the RV by echocardiography yields early detection of cardiac diseases, enhances risk stratification, and allows timely initiation of appropriate therapy.
