ABSTRACT With the appearance of the latest three/four-dimensional (3D/4D) ultrasound machine (HDliveFlow, Voluson E10, GE Healthcare, Zipf, Austria), HDliveFlow with glass-body rendering mode or silhouette mode will facilitate more precise assessments of the fetal heart and peripheral circulation. The resolution of 3D/4D color/power Doppler using the HDlive technique shows a significant improvement compared to conventional 3D/4D color/power Doppler and the fetal heart with great vessels, small peripheral vessels, and placental blood flow can now be clearly recognized. HDliveFlow with glass-body rendering mode or silhouette mode combines the advantages of a spatial view of the great arteries in addition to the visualization of anatomical landmarks, such as the spine or diaphragm. Its use may provide potential advantages in cases of congenital heart anomalies and placental vascularity over the use of conventional 3D/4D color/power Doppler. This novel technique may assist in the evaluation of the fetal cardiovascular system and fetoplacental vascularity, and offer potential advantages relative to conventional 2D color/power Doppler assessments. In this article, we present the latest state-of-the-art HDliveFlow with glass-body rendering mode or silhouette mode of normal and abnormal fetal hearts, placentas, and umbilical cords. We also discuss the present and future applicability of 3D/4D color/ power Doppler to assess the fetal circulation. HDliveFlow with glass-body rendering mode or silhouette mode may become an important modality in future research on fetal cardiac and placental blood flow, and assist in the prenatal diagnosis of fetal congenital heart disease and placental vascular abnormalities.

High Resolution Ultrasonography

Over the years, there have been several improvements in ultrasound technologies including high-resolution ultrasonography, linear transducer, radiant flow, three-/four-dimensional (3D/4D) ultrasound, speckle tracking of the fetal heart, and artificial intelligence. The aims of this review are to evaluate the use of these advanced technologies in obstetrics in the midst of new guidelines on and new techniques of obstetric ultrasonography. In particular, whether these technologies can improve the diagnostic capability, functional analysis, workflow, and ergonomics of obstetric ultrasound examinations will be discussed.

Abstract Critical aortic stenosis (AS) of the fetal heart causes a drastic change in the cardiac biomechanical environment. Consequently, a substantial proportion of such cases will lead to a single-ventricular birth outcome. However, the biomechanics of the disease is not well understood. To address this, we performed Finite Element (FE) modelling of the healthy fetal left ventricle (LV) based on patient-specific 4D ultrasound imaging, and simulated various disease features observed in clinical fetal AS to understand their biomechanical impact. These features included aortic stenosis, mitral regurgitation (MR) and LV hypertrophy, reduced contractility, and increased myocardial stiffness. AS was found to elevate LV pressures and myocardial stresses, and depending on severity, can drastically decrease stroke volume and myocardial strains. These effects are moderated by MR. AS alone did not lead to MR velocities above 3 m/s unless LV hypertrophy was included, suggesting that hypertrophy may be involved in clinical cases with high MR velocities. LV hypertrophy substantially elevated LV pressure, valve flow velocities and stroke volume, while reducing LV contractility resulted in diminished LV pressure, stroke volume and wall strains. Typical extent of hypertrophy during fetal AS in the clinic, however, led to excessive LV pressure and valve velocity in the FE model, suggesting that reduced contractility is typically associated with hypertrophy. Increased LV passive stiffness, which might represent fibroelastosis, was found to have minimal impact on LV pressures, stroke volume, and wall strain. This suggested that fibroelastosis could be a by-product of the disease progression and does not significantly impede cardiac function. Our study demonstrates that FE modelling is a valuable tool for elucidating the biomechanics of congenital heart disease and can calculate parameters which are difficult to measure, such as intraventricular pressure and myocardial stresses.

The physiology of the fetal heart differs significantly from that of the mature post-natal organ: e.g., the metabolic supply for adult cardiac contraction relies mainly on fatty acids; whereas, the fetal heart uses carbohydrates as its primary energy source. Limited morphological descriptions of the developing myocardium have appeared. However, additional studies are required to elucidate the ultrastructural changes occuring in the perinatal period when enormous physiological adjustments are made. Although adult animals are most often used in toxocological and pathological analyses, it is also important to investigate fetal cardiac responsiveness to various agents. The vulnerability of the ultrastructure of the fetal mouse myocardium to genetic and environmental assault is the subject of this report. The genetically determined effect on the heart was observed in mouse embryos homozygous for the cab (cardiac abnormality) mutation discovered by Essien.
