122. Identification of a hybrid myocardial zone in the mammalian heart after birth Full Text available with Trip Pro

Identification of a hybrid myocardial zone in the mammalian heart after birth Noncompaction cardiomyopathy is characterized by the presence of extensive trabeculations, which could lead to heart failure and malignant arrhythmias. How trabeculations resolve to form compact myocardium is poorly understood. Elucidation of this process is critical to understanding the pathophysiology of noncompaction disease. Here we use genetic lineage tracing to mark the Nppa+ or Hey2+ cardiomyocytes (...) as trabecular and compact components of the ventricular wall. We find that Nppa+ and Hey2+ cardiomyocytes, respectively, from the endocardial and epicardial zones of the ventricular wall postnatally. Interposed between these two postnatal layers is a hybrid zone, which is composed of cells derived from both the Nppa+ and Hey2+ populations. Inhibition of the fetal Hey2+ cell contribution to the hybrid zone results in persistence of excessive trabeculations in postnatal heart. Our findings indicate

123. Primitive Embryonic Macrophages are Required for Coronary Development and Maturation. Full Text available with Trip Pro

these issues, we investigated the functions of macrophage subsets resident within the developing heart, an organ replete with embryonic-derived macrophages.Using a combination of flow cytometry, immunostaining, and genetic lineage tracing, we demonstrate that the developing heart contains a complex array of embryonic macrophage subsets that can be divided into chemokine (C-C motif) receptor 2(-) and chemokine (C-C motif) receptor 2(+) macrophages derived from primitive yolk sac, recombination activating (...) gene 1(+) lymphomyeloid, and Fms-like tyrosine kinase 3(+) fetal monocyte lineages. Functionally, yolk sac-derived chemokine (C-C motif) receptor 2(-) macrophages are instrumental in coronary development where they are required for remodeling of the primitive coronary plexus. Mechanistically, chemokine (C-C motif) receptor 2(-) macrophages are recruited to coronary blood vessels at the onset of coronary perfusion where they mediate coronary plexus remodeling through selective expansion of perfused

124. De Novo Formation of a Distinct Coronary Vascular Population in Neonatal Heart Full Text available with Trip Pro

De Novo Formation of a Distinct Coronary Vascular Population in Neonatal Heart The postnatal coronary vessels have been viewed as developing through expansion of vessels formed during the fetal period. Using genetic lineage tracing, we found that a substantial portion of postnatal coronary vessels arise de novo in the neonatal mouse heart, rather than expanding from preexisting embryonic vasculature. Our data show that lineage conversion of neonatal endocardial cells during trabecular (...) compaction generates a distinct compartment of the coronary circulation located within the inner half of the ventricular wall. This lineage conversion occurs within a brief period after birth and provides an efficient means of rapidly augmenting the coronary vasculature. This mechanism of postnatal coronary vascular growth provides avenues for understanding and stimulating cardiovascular regeneration following injury and disease.

). Fetal heart rate traces, recorded for 30 min before and 60 min after neuraxial block, were categorised as normal, suspicious or pathological according to national guidelines. Sixty-one fetal heart rate tracings were analysed in the combined spinal-epidural group and 52 in the epidural group. No significant differences were found in fetal heart rate patterns, Apgar scores or umbilical artery and vein acid-base status between groups. However, in both combined spinal-epidural and epidural groups (...) Fetal effects of combined spinal-epidural vs epidural labour analgesia: a prospective, randomised double-blind study.

130. Correlation of arterial fetal base deficit and lactate changes with severity of variable heart rate decelerations in the near-term ovine fetus. (Abstract)

Correlation of arterial fetal base deficit and lactate changes with severity of variable heart rate decelerations in the near-term ovine fetus. Recent guidelines classify variable decelerations without detail as to degree of depth. We hypothesized that variable deceleration severity is highly correlated with fetal base deficit accumulation.Seven near-term fetal sheep underwent a series of graded umbilical cord occlusions resulting in mild (30 bpm decrease), moderate (60 bpm decrease), or severe (...) variable decelerations may result in significant base deficit increases, dependent on frequency. Modified guideline differentiation of mild/moderate vs severe variable decelerations may aid in the interpretation of fetal heart rate tracings and optimization of clinical management paradigms.Copyright © 2013 Mosby, Inc.

134. Reversed end-diastolic flow in the middle cerebral artery preceding death in a normally grown fetus. (Abstract)

Reversed end-diastolic flow in the middle cerebral artery preceding death in a normally grown fetus. Reversed diastolic flow in the middle cerebral artery has been described as a terminal sign in the growth-restricted fetus. The implication of this in a normally grown fetus is unknown.Middle cerebral artery Doppler velocimetry was performed at 28 weeks of gestation in the setting of decreased fetal movement and a category 2 fetal heart tracing. The middle cerebral artery pulsatility index (...) was elevated, and follow-up studies revealed reversed flow. The fetus had appropriate growth, with mild polyhydramnios and no signs of cardiomegaly, effusion, or hydrops. Fetal death was diagnosed 4 days later in the setting of extensive intracranial hemorrhage.Regardless of fetal growth, persistent reversed middle cerebral artery Doppler with an elevated pulsatility index may be a feature of impending death.

135. STRESS ZONES IN FOETAL ARTERIES Full Text available with Trip Pro

STRESS ZONES IN FOETAL ARTERIES In a study of the peripheral arteries of foetuses it was found that focal areas of intimal thickening and of splitting of the internal elastica had developed, the thickening being similar to that found in the coronary arteries. Characteristically the thickenings were found in the mouths of branches and in those vessels subject to pulsation. It is believed that they are physiological in nature and a response of the vascular wall to the stresses produced by focal (...) areas of impaired pulsation and not degenerative as formerly thought. The evolution of these arterial cushions is traced from early foetal life; their most important constituent is bundles of medial longitudinal muscle. Both thickening and splitting of the internal elastica are brought about by a radial reorientation and migration of the muscle cells of the media.

aim of intrapartum fetal surveillance is to prevent adverse perinatal outcomes arising from fetal metabolic acidosis related to labour. 2 As the fetal brain modulates the fetal heart rate (FHR) through an interplay of sympathetic and parasympathetic forces, fetal heart rate monitoring can be used as an indicator of whether or not a fetus is well oxygenated. 3 In the absence of risk factors FHR surveillance by continuous electronic fetal monitoring (CEFM) does not provide proven benefit and may (...) during labour 2 · Uses external Doppler US to monitor FHR and pressure transducers strapped to the abdomen to monitor uterine contractions 17 · Requires physical attachment to CTG machine if telemetry not available · Associated with high false positive results and inconsistent FHR tracing interpretations 5 Internal CTG- Fetal scalp electrode (FSE) · Recommended when: o Concerns with baseline variability o Difficulty: ?

139. Effect of magnesium sulfate on fetal heart rate patterns in the second stage of labor. (Abstract)

Effect of magnesium sulfate on fetal heart rate patterns in the second stage of labor. To estimate the effect of maternal exposure to magnesium sulfate on fetal heart rate characteristics during active labor.Within a 4-year retrospective cohort study of consecutive term deliveries reaching the second stage of labor, we compared women exposed to magnesium for severe preeclampsia to all women not exposed. Primary outcome was the electronic fetal monitoring tracing in the 30 minutes preceding (...) delivery. Secondary outcomes were fetal acidemia and nursery disposition. Attributable risk estimates and multivariable logistic regression were used to estimate the association between magnesium exposure and fetal heart rate characteristics. Unadjusted risk estimates for the association between fetal heart rate characteristics and neonatal outcomes were generated stratified by group.Of 5,387 women, 248 (4.6%) were exposed to magnesium. Magnesium exposure was associated with lower fetal heart rate
