“…In fact, more recent studies, which have incorporated the latest technological advances, point to the need to better evaluate STE reproducibility and its correlation with other morphometric and functional echocardiographic parameters before introducing STE into clinical practice. In recent years, FetalHQ ® has shown excellent reproducibility for the analysis of morphometric and functional cardiac parameters [ 26 , 27 , 30 , 32 , 55 , 56 , 57 , 58 ]. FetalHQ ® automatically defines 24 segments of the ventricles and provides information of the shape (SI) and radial systolic function (SF) by the calculation of the longitudinal and transverse diameter of each segment.…”

Fetal Heart Quantification (FetalHQ®) is a novel speckle tracking software that permits the study of global and regional ventricular shape and function from a 2D four-chamber-view loop. The 4D-Spatio Temporal Image Correlation (STIC) modality enables the offline analysis of optimized and perfectly aligned cardiac planes. We aimed to evaluate the feasibility and reproducibility of 4D-STIC speckle tracking echocardiography (STE) using FetalHQ® and to compare it to 2D STE. We conducted a prospective study including 31 low-risk singleton pregnancies between 20 and 40 weeks of gestation. Four-chamber view volumes and 2D clips were acquired with an apex pointing at 45° and with a frame rate higher than 60 Hz. Morphometric and functional echocardiography was performed by FetalHQ®. Intra- and interobserver reproducibility were evaluated by the intraclass correlation coefficient (ICC). Our results showed excellent reproducibility (ICC > 0.900) for morphometric evaluation (biventricular area, longitudinal and transverse diameters). Reproducibility was also good (ICC > 0.800) for functional evaluation (biventricular strain, Fractional Area Change, left ventricle volumes, ejection fraction and cardiac output). On the contrary, the study of the sphericity index and shortening fraction of the different ventricular segments showed lower reproducibility (ICC < 0.800). To conclude, 4D-STIC is feasible, reproducible and comparable to 2D echocardiography for the assessment of cardiac morphometry and function.

“…16,17 In our study, the growing trend of right ventricular end-diastolic diameter (RV) in the GDM group became higher than that in the control group, and the difference in two groups became larger in the whole observation period. The rapid increase of RV in GDM group may affect the entire cardiac structure of the fetal myocardium and increase the spherical index, [18][19][20] which may be a sign of reduced myocardial compliance.…”

Background: Gestational diabetes mellitus (GDM) is a complication of pregnancy strongly associated with an increased risk of structural fetal abnormalities. As the fetal heart grows quickly during the late-term pregnancy period, it is important to understand fetal heart growth before birth. This study explored how GDM affects fetal heart growth by evaluating basic echocardiography indicators during late pregnancy. Methods:This prospective, longitudinal study included 63 GDM patients (GDM group) and 67 healthy pregnant women (control group). All subjects underwent fetal echocardiography scans at gestational weeks 28-32, 32-36, and 36-40. Twelve echocardiographic indicators were assessed at each observation and analyzed by using a mixed model. Results:The left atrial diameter (LA) and left ventricular end-diastolic diameter (LV) similarly increased from the first to the third observation. The right ventricular enddiastolic diameter (RV) was significantly different between the groups, and a group × time interaction was detected. The tricuspid annular peak systolic velocity (s') increased more rapidly in the GDM than the control group during the first to second observations, and the group × time interaction was significant. The increase in the tricuspid annular plane systolic excursion (TAPSE) of the GDM group was "slow-fast", while that of the control group was "fast-slow", during three observations. After adjusting covariates, the group difference and interaction effect of TAPSE and RV remained significant. Conclusions:The differences in fetal right heart indicators between the GDM and control groups suggest that GDM may affect the structure and functional growth of the fetal right heart during late-term pregnancy.

This is in contrast with Rodríguez-L opez et al 21 and Rizzo et al 22 who assessed that cardiac shape was altered significantly, because the SI is reduced both in left and right ventricles in mild and severe FGR.…”

The aim of this review is to provide an up to date on the current use of fetal echocardiography in assessing the fetal cardiac function and its potential research and clinical applications. Despite classically is been used for prenatal diagnosis of fetal heart defects, assessment of fetal cardiac function has been recently proposed as a fundamental tool to assess pregnancies complicated by several disorders with long-term impact on post-natal cardiovascular health, such as placental insufficiency and fetal growth restriction. In this review we present anatomical and functional fetal cardiac development mechanisms and an overview of the currently available techniques for evaluating fetal heart function.
