Feridoun Sabzi, Aghigh Heidari
Prepartum or postpartum right ventricular thrombosis (RVT) is an exceedingly rare and potentially lethal phenomenon in pregnancy. We here report a case of a pregnant patient with near term pregnancy admitted for dyspnea, amniotic fluids discharge and labor pain in a gynecology center that an eight-month dead fetus was diagnosed and delivered vaginally by induction. A post delivery period was complicated by aggravation of her dyspnea and pleuritic chest pain that she referred for further evaluation in our cardiac center...

Hypoplastic left heart syndrome (HLHS) represents a variety of cardiac malformations that may result from errors in the early stages of cardiac development. HLHS includes a wide spectrum of cardiac malformations including hypoplasia of the left ventricle, ascending aorta, hypoplasia, or atresia of the aortic and mitral valves. Over the recent years, the improved resolution of advanced equipment with awareness and increased performance of second-trimester ultrasound examinations for the assessment of fetal anomalies have helped in understanding the spectrum and have expanded our knowledge of HLHS...

BACKGROUND: Late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) imaging has enabled the accurate assessment of myocardial infarction (MI). However, LGE CMR has not been performed successfully in the fetus, where it could be useful for animal studies of interventions to promote cardiac regeneration. We believe that LGE imaging could allow us to document the presence, extent and effect of MI in utero and would thereby expand our capacity for conducting fetal sheep MI research...

BACKGROUND: Intraventricular pressure difference (IVPD), the diastolic suction during early diastole, is known as a useful marker of myocardial diastolic function in adults with different heart diseases, but there are no studies of fetal IVPD. The aim of this study was to determine whether IVPD exists and changes prenatally and whether IVPD correlates with preexisting parameters to evaluate fetal cardiac diastolic function and ventricular dominance. METHODS: Cross-sectional study data (stroke volume, fetal cardiac output, E/A ratio, and myocardial performance index) from 117 healthy fetuses at 17 to 36 weeks of gestation were retrospectively evaluated...

The aim of stem cell therapy after cardiac injury is to replace damaged cardiac tissue. Human cardiac progenitor cells (CPCs) represent an interesting cell population for clinical strategies to treat cardiac disease and human CPC-specific antibodies would aid in the clinical implementation of cardiac progenitor based cell therapy. However, the field of CPC biology suffers from the lack of human CPC-specific markers. Therefore, we raised a panel of monoclonal antibodies (mAb) against CPCs Of this panel of antibodies, we show that mAb C1096 recognizes a progenitor-like population in the fetal and adult human heart and partially co-localize with reported CPC populations in vitro...

OBJECTIVE: To determine whether fetal isovolumetric time intervals can be an early sonographic marker of fetal anemia in fetuses with homozygous alpha thalassemia-1. METHODS: Pregnancies at risk for fetal homozygous alpha thalassemia-1 disease at 18-22 weeks were recruited before cordocentesis for hemoglobin typing. Isovolumetric contraction time (ICT) and isovolumetric relaxation time (IRT) intervals were measured by placing pulsed wave Doppler sample volume within the left ventricle to obtain the mitral and aortic waveform...

Testosterone exposure during pregnancy has been hypothesized as a mechanism for sex differences in brain and behavioral development observed in the postnatal period. The current study documents the natural history of maternal salivary testosterone from 18 weeks gestation of pregnancy to 6 months postpartum, and investigates associations with fetal heart rate, motor activity, and their integration. Findings indicate maternal salivary testosterone increases with advancing gestation though no differences by fetal sex were detected...

BACKGROUND: Despite decades of public education about dire consequences of prenatal alcohol exposure, drinking alcohol during pregnancy remains prevalent. As high as 40% of live-born infants exposed to alcohol during gestation and diagnosed with Fetal Alcohol Syndrome have congenital heart defects that can be life-threatening. In animal models, the methyl donor betaine, found in foods such as wheat bran, quinoa, beets and spinach, ameliorated neurobehavioral deficits associated with prenatal alcohol exposure (PAE) but effects on heart development are unknown...

Excessive fetal glucocorticoid exposure has been linked to increased susceptibility to hypertension and cardiac diseases in the adult life, a process called fetal programming. The cardiac contribution to the hypertensive phenotype of glucocorticoid-programmed progeny is less known, therefore, we investigated in vitro cardiac functional parameters from rats exposed in utero to betamethasone. Pregnant Wistar rats received vehicle (VEH) or betamethasone (BET, 0.1mg/kg, i.m.) at gestational days 12, 13, 18 and 19...

Calsarcin-1 deficient mice develop dilated cardiomyopathy (DCM) phenotype in pure C57BL/6 genetic background (Cs1-ko) despite severe contractile dysfunction and robust activation of fetal gene program. Here we performed a microRNA microarray to identify the molecular causes of this cardiac phenotype that revealed the dysregulation of several microRNAs including miR-301a, which was highly downregulated in Cs1-ko mice compared to the wild-type littermates. Cofilin-2 (Cfl2) was identified as one of the potential targets of miR-301a using prediction databases, which we validated by luciferase assay and mutation of predicted binding sites...

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 cardiac intervention (FCI) is a relatively new and continually evolving field, and, for select cardiac defects, offers the potential to alter the progression of the disease and improve outcomes. It is a procedure that requires a collaborative effort between maternal-fetal medicine, interventional cardiology and fetal echo/ultrasound specialists, as well as fetal and maternal anesthesiologists, nursing specialists, and social workers. This article reviews the most recently reported data and advances in FCI...

Infants with hypoplastic left heart syndrome and an intact or highly restrictive atrial septum (HLHS-IAS) represent a high risk subset. Fetal cardiac intervention (FCI) for fetuses with HLHS-IAS has been reported in single-institution series as a therapy that may improve outcomes. This study utilizes the International Fetal Cardiac Intervention Registry (IFCIR) to examine fetal and maternal characteristics and pregnancy and neonatal outcome data for FCI in this population.

Fetal alcohol spectrum disorder (FASD) is a common neurodevelopmental problem, but neuropathologic descriptions are rare and focused on the extreme abnormalities. We conducted a retrospective survey (1980-2016) of autopsies on 174 individuals with prenatal alcohol exposure or an FASD diagnosis. Epidemiologic details and neuropathologic findings were categorized into 5 age groups. Alcohol exposure was difficult to quantify. When documented, almost all mothers smoked tobacco, many abused other substances, and prenatal care was poor or nonexistent...

The late gestation fetal ECG (fECG) has traditionally been difficult to characterize due to the low fECG signal relative to high maternal noise. Although new technologies have improved the feasibility of its acquisition and separation, little is known about its development in late gestation, a period in which the fetal heart undergoes extensive maturational changes. Here, we describe a method for the chronic implantation of radiotelemetry devices into late gestation ovine fetuses to characterize parameters of the fECG following surgery, throughout late gestation, and in the perinatal period...

BACKGROUND: Cor triloculare biventriculare accounts for approximately 0.31% of cases of congenital heart disease (CHD). Moreover, people with cor triloculare biventriculare always have shorter life spans, and cases of gestation are rare. There have been various related reports of cor triloculare biventriculare in recent years. CASE PRESENTATION: We described an emergency cesarean section of a 30-year-old, 38-weeks-pregnant woman suffering from cardiac insufficiency and fetal distress...
