AIM: To determine whether Doppler evaluation at 20-24 weeks of gestation can predict reduced fetal size later in pregnancy or at birth. METHODS: Fetal biometry and Doppler velocimetry were performed in 2,986 women with a singleton pregnancy at 20-24 weeks of gestation. Predictive performances of the umbilical artery pulsatility index (UA-PI) or the mean uterine artery pulsatility index (UtA-PI) >95th percentile, middle cerebral artery pulsatility index, or cerebroplacental ratio (CPR) <5th percentile for early small for gestational age (SGA; <34 weeks of gestation), late SGA (≥34 weeks of gestation), or SGA at birth (birthweight <10th percentile) were analyzed...

Monitoring of fetal heart rate (FHR) is an important measure of fetal wellbeing during the months of pregnancy. Previous works on estimating FHR variability from Doppler ultrasound (DUS) signal mainly through autocorrelation analysis showed low accuracy when compared with heart rate variability (HRV) computed from fetal electrocardiography (fECG). In this work, we proposed a method based on empirical mode decomposition (EMD) and the kurtosis statistics to estimate FHR and its variability from DUS. Comparison between estimated beat-to-beat intervals using the proposed method and the autocorrelation function (AF) with respect to RR intervals computed from fECG as the ground truth was done on DUS signals from 44 pregnant mothers in the early (20 cases) and late (24 cases) gestational weeks...

BACKGROUND: Pre-eclampsia is associated with significant changes to the cardiovascular system during pregnancy. Eccentric and concentric remodelling of the left ventricle occurs, resulting in impaired contractility and diastolic dysfunction. It is unclear whether these structural and functional changes resolve completely after delivery. AIMS: The objective of the study was to determine cardiac diastolic function at delivery and one year post-partum in women with severe pre-eclampsia, and to determine possible future cardiovascular risk...

INTRODUCTION: Increase in Nitric Oxide (NO) may be important in vascular adaptation needed to accommodate increased uteroplacental blood flow as pregnancy advances. Hence, in certain conditions like Pregnancy Induced Hypertension (PIH) and Fetal Growth Restriction (FGR), NO donors may play an effective role in increasing uteroplacental perfusion. Transdermal route appears to be a safe and effective route. AIM: To evaluate the effect of nitroglycerine patch on Doppler velocity waveforms of the uterine, umbilical and fetal middle cerebral arteries in patients with chronic placental insufficiency...

Fetal Cardiology. Experiences from a tertiary referral centre in Stockholm, Sweden This review provides a brief overview of the current position and clinical experiences of fetal cardiology at a tertiary referral centre in Stockholm, Sweden. In Stockholm, more than 60% of congenital cardiac defects requiring surgery or catheter intervention before one year of age are detected before birth. This not only results in termination of pregnancy in the majority of cases carrying a poor prognosis, but also conveys a better postnatal care and prognosis in cases of continued pregnancy...

Fetal growth restriction (FGR) affects 7-10% pregnancies. Conventional and tissue Doppler imaging has noted cardiac compromise during fetal and early neonatal periods in this cohort. In this article, we discuss the use of salient ultrasound parameters across age groups. During fetal life, certain feto-placental sonographic parameters have been linked to adverse perinatal outcomes and are predictive of later life hypertension. During the early postnatal period altered morphometry (hypertrophied and globular hearts) with sub-clinical impairment of cardiac function has been noted in both term and preterm infants with FGR...
