BACKGROUND: Fetal electrocardiogram (fECG) can detect QRS signals in fetuses from as early as 17 weeks' gestation; however, the technique is limited by the minute size of the fetal signal relative to noise ratio. The aim of this study was to evaluate precise fetal cardiac time intervals (fCTIs) with the help of a newly developed fetal ECG device (Monica Healthcare System). METHODS: In a prospective manner we included 15-18 healthy fetuses per gestational week from 32 weeks onwards...

Cardiac rhabdomyoma, a type of benign myocardial tumor, is regarded as the most common fetal cardiac tumor. Rhabdomyomas are usually found before birth or during the first year of life. It is widely accepted that rhabdomyomas are strongly associated with tuberous sclerosis, and tend to regress spontaneously without surgical excision. However, if the tumor has caused significant obstruction or refractory arrhythmias, the surgery should be advocated. Most of the surgeries for pediatric cardiac tumors are performed under cardiopulmonary bypass (CPB) with cardioplegia...

Abnormal placental development is frequent in nuclear transfer (NT) pregnancies and is likely to be associated with altered epigenetic reprogramming. In the present study, fetal and placental measurements were taken on Day 60 of gestation in cows with pregnancies produced by AI, IVF and NT. Placentas were collected and subjected to histological evaluation, the expression of genes important in trophoblast differentiation and expression of the placental imprinted gene pleckstrin homology-like domain, family A, member 2 (PHLDA2), as well as chromatin immunoprecipitation (ChIP) for histone marks within the promoter of PHLDA2...

Heart development is a complex process requiring dynamic transcriptional regulation. Disturbance of this process will lead to severe developmental defects such as congenital heart disease/defect (CHD). CHD is a group of complex disorder with high genetic heterogeneity, common pathways associated with CHD remains largely unknown. In the manuscript, we focused on the tissue specific genes in human fetal heart samples to explore such pathways. We used the RNA microarray dataset of human fetal tissues from ENCODE project to identify genes with heart tissue specific expression...

BACKGROUND: D-transposition of the great arteries (D-TGA) is one of the most common critical neonatal heart defects. Although there are clinical advantages to a prenatal diagnosis, D-TGA has had low prenatal detection internationally. Recent obstetrical ultrasound guidelines incorporating screening of cardiac outflows may improve prenatal detection of D-TGA. We sought to evaluate trends in the prenatal detection of D-TGA with/without ventricular septal defect (VSD) in Alberta over the past 13 years, examining the potential impact of enhanced ultrasound guidelines in 2009-2010 and 2013 and factors impacting detection...

Children from economically disadvantaged families experience worse cognitive, psychiatric, and medical outcomes compared to more affluent youth. Preclinical models suggest some of the adverse influence of disadvantage could be transmitted during gestation via maternal immune activation, but this hypothesis has not been tested in humans. It also remains unclear whether prenatal interventions can mitigate such effects. To fill these gaps, we conducted two studies. Study 1 characterized the socioeconomic conditions of 79 women during pregnancy...

Obstetrician-gynecologists often are the sole providers of health care to female patients. Because cardiovascular disease is the leading cause of death in women in the United States, obstetrician- gynecologists must be aware of the risk factors, symptoms, and signs of cardiovascular disease and arrhythmia. Furthermore, they must be prepared to identify and treat common types of arrhythmia in this population and refer patients to cardiology for specialized care. Understanding the role of pregnancy among women with arrhythmia is critically important to optimize both maternal and fetal outcomes...

BACKGROUND: Reasons for the increased incidence of cesarean delivery among women with inflammatory bowel disease remain unclear. We assessed cesarean delivery incidence and factors influencing mode of delivery in women with inflammatory bowel disease. METHODS: We performed a 10-year retrospective cohort study of nulliparous women who delivered a singleton infant at our institution. We compared the risk of each mode of delivery in women with Crohn's disease and ulcerative colitis with women without inflammatory bowel disease...

Infants born to women with diabetes or obesity are exposed to excess circulating fuels during fetal heart development and are at higher risk of cardiac diseases. We have previously shown that late-gestation diabetes, especially in conjunction with a maternal high-fat (HF) diet, impairs cardiac functions in rat-offspring. This study investigated changes in genome-wide histone modifications in newborn hearts from rat-pups exposed to maternal diabetes and HF-diet. Chromatin-immunoprecipitation-sequencing revealed a differential peak distribution on gene promoters in exposed pups with respect to acetylation of lysines 9 and 14 and to trimethylation of lysines 4 and 27 in histone H3 (all, false discovery rate, FDR < 0...

Maternal tachyarrhythmia is a common complication during pregnancy due to hormonal changes that enhance pre-existing arrhythmias or induce new arrhythmias in the presence of congenital heart defects in pregnant females. Presence of tachyarrhythmia during pregnancy poses risk to the mother and fetus, calling for proper treatment with medications. Use of antiarrhythmic drugs in cases of maternal tachyarrhythmia must give due consideration of potential teratogenic side effects. Utilization of antiarrhythmic drugs during pregnancy has been well studied; some result in minimal fetal harm or none at all...

Background -Pregnant women carrying fetuses with heart defects and women with hypertensive disorders of pregnancy both often exhibit angiogenic imbalances, suggesting that the same mechanisms are involved in the etiology of the former and the pathophysiology of the latter. We conducted a register-based cohort study to determine whether offspring congenital heart defects are associated with an increased risk of hypertensive disorders of pregnancy, and whether the mechanisms driving any association are primarily maternal or fetal...

Takayasu arteritis is a rare, chronic vasculitis of unknown etiology characterized by inflammation of the aorta and its main branches. Although Takayasu arteritis mostly affects women of childbearing age, there is a paucity in the literature on pregnancy associated with Takayasu arteritis. Pregnant patients are at increased risk of cardiovascular complications, including hypertension and congestive heart failure, which may jeopardize both maternal and fetal outcomes. Furthermore, optimal management has not yet been established for pregnant patients with Takayasu arteritis, posing a clinical challenge...

Human pluripotent stem cells derived cardiomyocytes (PSC-CMs) have been widely used for disease modeling, drug safety screening, and preclinical cell therapy to regenerate myocardium. Most studies have utilized PSC-CM grown in vitro for a relatively short period after differentiation. These PSC-CMs demonstrated structural, electrophysiological, and mechanical features of primitive cardiomyocytes. A few studies have extended in vitro PSC-CM culture time and reported improved maturation of structural and electromechanical properties...

This paper focuses on the design, realization, and verification of a novel phonocardiographic- based fiber-optic sensor and adaptive signal processing system for noninvasive continuous fetal heart rate (fHR) monitoring. Our proposed system utilizes two Mach-Zehnder interferometeric sensors. Based on the analysis of real measurement data, we developed a simplified dynamic model for the generation and distribution of heart sounds throughout the human body. Building on this signal model, we then designed, implemented, and verified our adaptive signal processing system by implementing two stochastic gradient-based algorithms: the Least Mean Square Algorithm (LMS), and the Normalized Least Mean Square (NLMS) Algorithm...

Cardiovascular disease (CD) is a major burden for Western society. Regenerative medicine has provided encouraging results, yet it has not addressed the focal defects causing CD and mainly related to the inefficient repair programme of the heart. In this scenario, stem cells have been broadly investigated and their paracrine effect proposed as a possible working strategy to boost endogenous mechanisms of repair and regeneration from within the cardiac tissue. The scientific community is now focusing on identifying the most effective stem cell secretome, as the whole of bioactive factors and extracellular vesicles secreted by stem cells and endowed with regenerative potential...
