Figure 1: 2D-Speckle-Tracking (2D-STE) analysis using Fetal Heart Quantification (fetalHQ®). a: Determination of the global size and shape of the fetal heart at end-diastole by measurement of two cardiac diameters in the longest dimension; b, c: Identification and selection of an optimal fetal cardiac cycle using anatomical M-mode (AMM); d, e: Manual tracing along the systolic endocardial border in a three-point-analysis (septal and lateral annulus, apex) exemplified for the right ventricle and automatic delineation of the endocardium; f: Landing-page with parameters of fetal cardiac function. EndoGLS = Endocardial longitudinal strain.
