A circular shunt (CS) is a life-threatening condition consisting of massive shunting of systemic arterial blood via the ductus arteriosus to the left ventricle without traversing the lungs. In the prenatal circulation, it mainly occurs in severe Ebstein anomaly (EA) from unrestricted ductal flow and significant pulmonary and tricuspid regurgitation. We aimed to improve the fetal hemodynamics and chances of survival of affected fetuses by inducing ductal constriction with transplacental non-steroidal anti-inflammatory drugs (NSAIDs)...

OBJECTIVE: Our aim was to investigate the association between LGA and stillbirth to determine if the LGA fetus may benefit from antenatal testing. METHODS: We performed a retrospective cohort study of singleton ongoing pregnancies at 24 weeks gestation undergoing routine second trimester anatomy ultrasound from 1990-2009. Pregnancies complicated by fetal anomalies, aneuploidy, missing birthweight information and small for gestational age were excluded. Appropriate for gestational age (AGA) and LGA were defined as birthweight 10th -90th percentile and >90th percentile by the Alexander growth standard, respectively...

Ultrasound evidence of pelvic cysts in women of reproductive age is a quite frequent event in gynecological practice. In the clear majority of cases, they derive from the ovary, the tubes, or the uterus (i.e. cystic adenomyomas, colliquated myomas) while a small part of them can originate from the bowel.

Absence of atrial communication in hypoplastic left heart syndrome (HLHS) produces severe obstruction of pulmonary blood flow frequently causing vascular injury. Any surviving fetuses suffer high neonatal mortality (50%) from profound hypoxemia since oxygenated blood cannot exit the left atrium (LA). (1,2) Postnatal interventions are suboptimal due to progressive hypoxemia/acidosis that occurs until such time as the inter-atrial septum (IAS) is opened and a left to shunt created.

OBJECTIVES: Fetal growth restriction (FGR) is a major risk factor for stillbirth and most commonly arises from uteroplacental insufficiency. Despite clinical examination and third trimester fetal biometry, cases of FGR often remain undetected antenatally. Placental insufficiency is known to be associated with altered blood flow resistance in maternal, placental, and fetal vessels. We evaluated the performance of individual, and combined Doppler blood flow resistance measurements for the prediction of term FGR...

OBJECTIVES: To investigate the relationship between fetal congenital heart defects (CHD) and placental perfusion assessed by uterine artery pulsatility index (UtA-PI) in relation to development of preeclampsia (PE). METHODS: This was a prospective screening study in singleton pregnancies at 19-24 weeks' gestation. Transvaginal ultrasound was used to measure the UtA-PI and the values were converted into multiples of the normal median (MoM). Median MoM values in pregnancies with fetuses with isolated major CHD were compared to those without CHD in relation to development of PE...

OBJECTIVE: Pregnant women with congenital heart disease (CHD) have an increased chance of abnormal uteroplacental flow (UPF) measured from second trimester onwards. This is related to pregnancy complications affecting mother and baby. Maternal right ventricular (RV) dysfunction has been suggested as predisposing factor. First trimester UPF screening, followed by therapeutic strategies, is effective in preventing pregnancy complications. The study aim was to relate first trimester UPF measurements to pre-pregnancy maternal cardiac function and pregnancy complications...
