Intrauterine growth restriction, a common consequence of prenatal hypoxia, is a leading cause of fetal morbidity and mortality with a significant impact on population health. Hypoxia may increase placental oxidative stress and lead to an abnormal release of placental-derived factors, which are emerging as potential contributors to developmental programming. Nanoparticle-linked drugs are emerging as a novel method to deliver therapeutics targeted to the placenta and avoid risking direct exposure to the fetus...

BACKGROUND: Premature restriction or closure of foramen ovale (FO) in otherwise structurally normal hearts may be associated with right ventricular dilation, tricuspid regurgitation, pericardial effusion, heart failure, even poor perinatal outcomes. Data about these rare conditions are lacking. METHODS: We retrospectively reviewed the echocardiographic records of 9704 fetuses seen from 2010 to 2014 in Beijing Anzhen Hospital, a regional and national referral center, to ascertain the presence of restriction or closure of FO...

Sildenafil is a potential new treatment for placental insufficiency in human pregnancies as it reduces the breakdown of vasodilator nitric oxide. Pulmonary vasodilatation is observed in normoxemic fetuses following sildenafil administration. Placental insufficiency often leads to fetal hypoxemia that can cause pulmonary vasoconstriction and fetal cardiac dysfunction as evidenced by reduced isovolumic myocardial velocities. We tested the hypotheses that sildenafil, when given directly to the hypoxemic fetus, reverses reactive pulmonary vasoconstriction, increases left ventricular cardiac output by increasing pulmonary venous return, and ameliorates hypoxemic myocardial dysfunction...

OBJECTIVE: Assisted reproductive technology (ART) has been associated with a higher incidence of congenital anomalies, including a specific increase in the rate of congenital heart defects (CHD). In this study, the rate of CHD in pregnancies resulting from ART at a single high-risk pregnancy referral center are compared to the published literature. METHODS: Pregnancies were screened by fetal echocardiography for the indication of ART over a 2-year period. CHD were classified as either mild or severe based on the need for postnatal surgical intervention...

M-mode echocardiography has been playing an important role in the diagnosis of fetal tachyarrhythmia. We recently encountered a neonatal case of atrial flutter with 2:1 atrioventricular conduction. However, M-mode erroneously indicated 1:1 atrioventricular movement. While the movement of the atrial wall far from the atrioventricular valve was much faster than that of the ventricular wall, the atrial wall adjacent to the atrioventricular valve fully synchronized to that of the ventricular wall. Thus, to avoid this novel pitfall, it would be important to add an additional assessment focusing on the movement of the atrial wall far from the ventricle...

Advances in prenatal imaging have improved the examination of the fetal cardiovascular system. Fetal echocardiography facilitates the prenatal diagnosis of congenital heart disease (CHD) and through sequential examination, allows assessment of fetal cardiac hemodynamics, predicting the evolution of anatomical and functional cardiovascular abnormalities in utero and during the transition to a postnatal circulation at delivery. This approach allows detailed diagnosis with prenatal counseling and enables planning to define perinatal management, selecting the fetuses at a risk of postnatal hemodynamic instability who are likely to require a specialized delivery plan...

We report three-dimensional imaging of a rare finding of Ebstein's anomaly of the tricuspid valve in a patient with hypoplastic left heart syndrome, which has been previously reported only by two-dimensional echocardiography. A fetal echocardiogram was performed at 19 weeks that showed a moderately hypoplastic left ventricle, severely hypoplastic mitral valve, a severely hypoplastic aortic valve, and a dysplastic tricuspid valve. Post Caesarean delivery at 40 weeks of gestation, a transthoracic echocardiogram confirmed the findings seen on the fetal echocardiogram...

Congenital heart defect (CHD) is one of the most common birth defects and is the leading cause of neonatal death. Currently, there are no biomarkers available for prenatal diagnosis of CHD. Clinical strategies to diagnose CHD mostly depend on fetal echocardiography. Recent advances in "omics" techniques have opened up new possibilities for biomarker discoveries. In this review, we discuss recent advances in prenatal detection of CHD using biomarkers obtained by "omics" approaches, including genomics, proteomics, metabolomics, and others...

BACKGROUND/AIMS: Cardiac hypertrophy is a major outcome and compensatory response of the cardiovascular system to hemodynamic and additional stress responses that ultimately lead to heart failure. Auranofin (Aur) has been used for treating rheumatic arthritis for several decades. Aur is a 19S proteasome-associated deubiquitinase inhibitor, and inhibition of the proteasome is speculated to reverse cardiac hypertrophy. However, the role of the deubiquitinases, especially 19S proteasome-associated deubiquitinases, in the regulation of cardiac remodeling remains poorly understood...

Congenital aneurysms and diverticula of the heart are rare anomalies and their prenatal diagnosis is challenging. Fetuses with suspected cardiac aneurysms on ultrasound (US) screening should undergo targeted fetal echocardiography, postnatal imaging, and follow-ups. Herein, we describe the second trimester US scan and postnatal cardiac magnetic resonance imaging (MRI) findings of a baby girl with concurrent septal and right ventricular cardiac aneurysms. Other cardiac and extra-cardiac structures were normal...

The ductus arteriosus (DA) is a crucial part of the fetal circulation, both in the normal fetus and in critical congenital heart disease (CHD). It allows shunting between the pulmonary and systemic circulations. In physiological prenatal conditions, the DA lets the majority of right ventricular output bypass the fluid-filled, high-resistance lungs. The DA can cause hemodynamic compromise in the fetus and neonate when constricted or absent (in isolation or in patients with CHD) and may lead to pre- or postnatal sequelae within other systems when forming part of a vascular ring...

BACKGROUND: Fetal cardiovascular magnetic resonance (CMR) imaging may provide a valuable adjunct to fetal echocardiography in the evaluation of congenital cardiovascular pathologies. However, dynamic fetal CMR is difficult due to the lack of direct in-utero cardiac gating. The aim of this study was to investigate the effectiveness of a newly developed Doppler ultrasound (DUS) device in humans for fetal CMR gating. METHODS: Fifteen fetuses (gestational age 30-39 weeks) were examined using 1...

Partial anomalous pulmonary venous connection (PAPVC) is a rare malformation. We describe a case of PAPVC, in which the left pulmonary veins coursed to the left innominate vein through a vertical vein and finally drained into the right superior vena cava; the right pulmonary veins were connected to the left atrium. Tracing the origin and destination of abnormal vessels presented at the three-vessel and trachea view is useful for the diagnosis. Four-dimensional echocardiography with high-definition flow imaging and spatiotemporal image correlation facilitates the identification of the drainage of fetal pulmonary veins, which should be considered as a complementary modality in obstetric ultrasonic examination when cardiac abnormalities are suspected...
