Hearing loss in infants with persistent fetal circulation.
Pediatrics, 1988Infants with the diagnosis of persistent fetal circulation were evaluated for hearing loss. From Jan 1, 1982, to Jan 1, 1984, 28 infants with this diagnosis were retrospectively identified, and 18 were evaluated by formal audiologic testing. Additionally,

Intrauterine growth restriction is associated with abnormalities in the fetal circulation. These abnormalities are currently best understood in the umbilical arterial and venous systems. Changes in intracardiac velocities are more variable as well as more difficult to detect.

Circulating Fetal RNA in Maternal Plasma
Annals of the New York Academy of Sciences, 2001Abstract: The discovery of cell‐free nucleic acids in plasma has opened up new possibilities for noninvasive clinical diagnosis. We demonstrate the presence of cell‐free fetal RNA in maternal plasma, indicating that plasma fetal RNA might be used as a marker for noninvasive prenatal diagnosis.

Ultrasound evaluation of the venous system is now a compulsory part of the haemodynamic assessment of the fetus. Once umbilical venous flow was introduced1,2 and its pulsatile pattern discovered in the compromised fetus,3 other sections of the venous system have been added or explored for possible diagnostic use: the inferior and superior vena cava,4,5

Fetal and Neonatal Pulmonary Circulation
Annual Review of Physiology, 1979During fetal life, gas exchange is carried out in the placenta. The lung does not have a physiological role, apart from possible metabolic functions which include secretion of hormones, enzymatic conversion of inactive substances to functional hormones, and degradation of active materials to inactive metabolites.

Physiology of the fetal circulation
Seminars in Fetal and Neonatal Medicine, 2005Our understanding of fetal circulatory physiology is based on experimental animal data, and this continues to be an important source of new insight into developmental mechanisms. A growing number of human studies have investigated the human physiology, with results that are similar but not identical to those from animal studies.

Embryology and Fetal Circulation
AJN, American Journal of Nursing, 1978first week of embryonic development, and into the third week of gestation, the developing embryo's nutritional needs are supplied by diffusion. After the third week of development, nutritional requirements of the embryo can no longer be met by diffusion alone; the heart and vascular systems develop rapidly.

This chapter details the development of the renal vasculature, the RAS, and the neural supply to the kidney. The sensitivity of the developing kidney to disruption of the activity of the fetal RAS is described. The fetal kidney has a high RVR and a low RBF and GFR.
