Accumulating data on the human fetal circulation shows the similarity to the experimental animal physiology, but with important differences. The human fetus seems to circulate less blood through the placenta, shunt less through the ductus venosus and foramen ovale, but direct more blood through the lungs than the fetal sheep. However, there are substantial individual variations and the pattern changes with gestational age. The normalised umbilical blood flow decreases with gestational age, and… Expand
Core Concepts: Fetal Cardiac Physiology
TLDR
The fetal myocardium and circulation differ from that of the adult in many important ways, and the fetus has unique methods to adapt to intrauterine stressors on the cardiovascular system. Expand
Placental Gas Exchange and the Oxygen Supply to the Fetus.

TLDR
The oxygen supply of the fetus depends on the blood oxygen content and flow rate in the uterine and umbilical arteries and the diffusing capacity of the placenta and the underlying mechanisms are a current focus of research. Expand
Clinical Significance of Ductus Venosus Waveform as Generated by Pressure-volume Changes in the Fetal Heart
TLDR
This review serves to improve the understanding of the mechanisms that regulate the blood flow redistribution between the fetal liver circulation and fetal heart and the clinical significance of the ductus venosus waveform as generated by pressure-volume changes in the fetal heart. Expand
Simulation and Analysis of Umbilical Blood Flow using Markov-based Mathematical Model
TLDR
Simulation results show that the umbilical artery blood flow velocity waveform depends on gestation age, fetal heart rate, uterine contraction and placental insufficiency, and the Doppler indices calculated from simulation helps in predicting both maternal abnormalities at various degrees of the conductivity to the blood flow passage. Expand
Multiscale modelling of the feto–placental vasculature
TLDR
A new anatomically based and multiscale approach to modelling the feto–placental circulation is presented, showing that normal asymmetry in shape does not affect placental efficiency, however, the size and number of small capillary vessels is predicted to have a large effect on feto-placenta resistance and flow heterogeneity.

TLDR
The interatrial and ducto-umbilical pressure gradients can be measured noninvasively in order to follow the hemodynamic of the fetal circulatory system. Expand
The role of blood flow distribution in the regulation of cerebral oxygen availability in fetal growth restriction.
TLDR
The model indicated that cerebral oxygen availability is increasingly dependent on the cardiac output distribution as the fetus gains weight, and the optimal ratio was found to increase as the hypoxic state of FGR worsens. Expand
Evaluation of fetal cerebrovascular circulation and brain development: the role of ultrasound and Doppler.
  • S. Degani

  • 2009
TLDR
Anatomic and physiological considerations of cerebral vasculature in healthy and disease states are relevant in studying brain development and variations in fetal brain blood perfusion and the major role of ultrasound and Doppler modalities in the evaluation of fetal cerebrovascular circulation is enabled by implementation of these considerations. Expand
Inverse solution of the fetal-circulation model based on ultrasound Doppler measurements
TLDR
The model indicated significant increase in cardiac output distribution towards the brain and in the degree of blood shunted by the ductus venosus, indicating severe brain-sparing state in these fetuses. Expand
Inverse Solution of the Fetal-Circulation Model Based on Ultrasound Doppler Measurements
TLDR
In conclusion, patient-specific modeling may provide a reliable estimate of the important hemodynamic indices of the fetal circulation which may be clinically relevant for the management of FGR pregnancies. Expand

Distribution and regulation of blood flow in the fetal and neonatal lamb.
TLDR
The patterns of blood flow in the fetal liver and heart, and the preferential streaming of water flow, which favors distribution of oxygen to the brain and myocardium are described, are described. Expand

TLDR
Evidence is presented indicating that prostaglandin E2 and prostaglandsin I2 are natural relaxants, respectively, for the ductus arteriosus and theductus venosus, and both vascular shunts share the dependence on an endogenous cytochrome P-450 mechanism to develop their contractile tone. Expand
Effects of Ductus Venosus Obstruction on Liver and Regional Blood Flows in the Fetal Lamb
TLDR
It is concluded that obstruction of the ductus venosus has no effect on regional blood flow distribution or oxygen delivery in normoxemic or hypoxemic animals and is not crucial in regulating umbilical venous return to the central fetal circulation. Expand
Distribution of the circulation in the normal and asphyxiated fetal primate.
TLDR
The blood flow to the heart, brain, and adrenal per gram of tissue was maintained by an increase in the distribution of cardiac output to these organs. Expand

TLDR
Shape, viscosity, compliance, and particularly the diameter of the inlet are suggested to influence the pulsatility of the blood velocity at the ductus venosus inlet--and determine the degree of wave transmission into the umbilical vein. Expand
Regulation of blood flow through the ductus venosus.

The purposes of this review are to summarize the data currently available on the regulation of ductus venosus blood flow in fetal and neonatal life and to identify those factors that affect ductus Venosus closure after birth. Expand

TLDR
Recent evidence points to an important role for altered vascular structure in growth‐retarded pregnancies, and nitric oxide is now considered to contribute to tonic reduction in vascular resistance. Expand

The circulation was studied in 33 previable human fetuses delivered by hysterotomy, while the placenta was still attached, and there was a fairly uniform decrease in proportion of CO distributed to theplacenta, probably owing to umbilical vessel constriction. Expand
