L Yeo, R Romero
OBJECTIVE: To evaluate the performance of color and bidirectional power Doppler ultrasound combined with Fetal Intelligent Navigation Echocardiography (FINE) in examining the fetal heart. METHODS: A prospective cohort study was conducted of fetuses in the second and third trimesters with a normal heart or with congenital heart disease (CHD). One or more spatiotemporal image correlation (STIC) volume datasets, combined with color or bidirectional power Doppler (S-flow) imaging, were acquired in the apical four-chamber view...

BACKGROUND: Complete atrioventricular block in fetuses is known to be mostly associated with autoimmune disease and can be irreversible if no steroids treatment is provided. Conventional methods used in clinical practice for diagnosing fetal arrhythmia are limited since they do not reflect the primary electrophysiological conduction processes that take place in the myocardium. The non-invasive fetal electrocardiogram has the potential to better support fetal arrhythmias diagnosis through the continuous analysis of the beat to beat variation of the fetal heart rate and morphological analysis of the PQRST complex...

OBJECTIVE: To evaluate the importance of assessment of fetal cardiac output (CO) for the prediction of complications of pregnancy. METHODS: We evaluated 65 fetuses and all of them had a fetal cardiac scan at 20 to 24 weeks of pregnancy. To measure CO, diameters (d) of the left right ventricle outflow tract were measured just above the valves. Each left CO (LCO) and right CO (RCO) was derived using the following equation: CO = velocity time integral × π × d(2)/4 × heart rate...

OBJECTIVES: Maternal gestational diabetes (GDM) is known to influence fetal physiology. Phase-rectified signal averaging (PRSA), an innovative signal processing technique, can be used to investigate signals obtained from fetal heart. The PRSA calculated variables "average acceleration capacity" (AAC) and "average deceleration capacity" (ADC) are established indices of autonomic nervous system (ANS) function. The aim of this study was to evaluate the influence of gestational diabetes on the fetal ANS in human pregnancy using PRSA...

Valvular heart disease in women of childbearing age poses an increased risk of adverse maternal and fetal outcomes, and management in pregnancy can be challenging. Ideally, patients with suspected valvular disease should have preconception counseling by a multidisciplinary team including cardiologists with expertise in pregnancy and a maternal-fetal medicine specialist. Preconception planning should include a cardiac assessment of maternal risk, determination of frequency of surveillance, and a cardiovascular management plan during delivery...

Infants born with potentially life-threatening conditions of omphalocele and gastroschisis may require long-term hospitalization. We aimed to compare the outcomes of these two conditions occurring over a 16-year period (2001-16). It is a retrospective study of 19 newborns undergoing surgery for these two abdominal wall defects (8 patients with omphalocele and 11 cases of gastroschisis). The average birth weights for the newborns with omphaloceles and gastroschisis were 2554.5 g and 2248.6 g respectively. Associated anomalies included trisomy 18, Beckwith-Wiedemann syndrome, congenital heart disease, Meckel's diverticulum, inguinal hernias, renal deformities, limb deformities, cryptorchidism, body stalk anomalies, and closed gastroschisis...

I was a second-year neonatal-perinatal fellow in a meeting between other members of the neonatal intensive care team and parents who had just received devastating news about their planned-for and highly desired baby, born after what had been an uncomplicated pregnancy. At home, a little sister was waiting to meet her new brother. These conversations are never easy, but this one I found particularly disturbing. John had been born at term via emergency cesarean section after his mother, Muriel, had come for a routine obstetrical visit and reported decreased fetal movement...

Improvements in surgery have resulted in more women with repaired congenital heart disease (CHD) surviving to adulthood. Women with CHD, who wish to embark on pregnancy require prepregnancy counselling. This consultation should cover several issues such as the long-term prognosis of the mother, fertility and miscarriage rates, recurrence risk of CHD in the baby, drug therapy during pregnancy, estimated maternal risk and outcome, expected fetal outcomes and plans for pregnancy. Prenatal genetic testing is available for those patients with an identified genetic defect using pregestational diagnosis or prenatal diagnosis chorionic villus sampling or amniocentesis...

The developing fetus has some unique physiological properties that differ from properties in extra-uterine life. The fetus exists in a hypoxemic condition as a result of the presence of the placenta, which serves as a limiting interface between maternal and fetal circulation. In addition, the fetus is prone to be exposed to uterine contractions, which place it under a further hypoxic burden. Thus, the fetal response to hypoxic insults is important. There has been marked progression in the understanding of fetal physiology since the introduction of the 'chronic preparation model'...

BACKGROUND: The use of neonatal 3-lead electrocardiograms (Neo-ECG) is suggested as a method for the assessment of heart rate (HR) in neonatal resuscitation, but primary childbirth facilities (i.e., maternity clinics or maternity homes) are not sufficiently equipped for this. The objective of this study was to confirm the potential of using a handheld fetal Doppler device (FDD), widely used to assess HR in labor room resuscitation, and to compare its equivalency to Neo-ECG. METHODS: In low-risk full-term infants, HR was measured 5 times/minute in minutes 1-5 postpartum using the FDD and Neo-ECG, and their equivalence was compared...

INTRODUCTION: Several studies report a decrease of fetal heart rate (FHR) short-term variation (STV) after corticosteroids for improvement of fetal maturity and advice not to deliver a fetus for low STV within 2-3days after corticosteroids. However, literature is not unanimous in this respect. This study intends to asses STV longitudinally after corticosteroid administration. MATERIAL AND METHODS: A retrospective cohort study in a tertiary perinatal centre from 2009 to 2015 included all women who had been treated with corticosteroids at gestational age of 26-34 weeks, had a computerized cardiotocography (cCTG) before and after medication and did not deliver within 48h...

Infective endocarditis (IE) during pregnancy is a rare but serious condition. Cardiopulmonary bypass during pregnancy has a high rate of fetal morbidity and mortality. We here report the case of a 22-year-old pregnant woman with confirmed IE. Multiple large cardiac valve vegetations, severe aortic valve regurgitation, and hemodynamic compromise were observed. With full implementation of fetal monitoring and protection strategies, open heart surgery was performed at 31.4 weeks' gestation to aid survival, followed by an elective cesarean delivery at 34...

Analysis of heart rate variability (HRV) is a recognized tool in the assessment of autonomic nervous system (ANS) activity. Indeed, both time and spectral analysis techniques enable us to obtain indexes that are related to the way the ANS regulates the heart rate. However, these techniques are limited in terms of the lack of thresholds of the numerical indexes, which is primarily due to high inter-subject variability. We proposed a new fetal HRV analysis method related to the parasympathetic activity of the ANS...
