BACKGROUND: Human induced pluripotent stem cells (hiPSC) harbor the potential to differentiate into diverse cardiac cell types. Previous experimental efforts were primarily directed at the generation of hiPSC-derived cells with ventricular cardiomyocyte characteristics. Aiming at a straightforward approach for pacemaker cell modeling and replacement, we sought to selectively differentiate cells with nodal-type properties. METHODS: hiPSC were differentiated into spontaneously beating clusters by co-culturing with visceral endoderm-like cells in a serum-free medium...

OBJECTIVES: Prenatal diagnosis of complex congenital heart disease (CHD) during routine obstetric ultrasound (US) examinations improves postnatal outcomes, but sensitivity is low (<40%). Our objective was to improve our prenatal detection of complex CHD with implementation of a specific screening protocol. METHODS: From January 2003 to December 2013, 506 consecutive confirmed cases of complex CHD in the province of Manitoba, Canada, were analyzed to compare the sensitivity and positive predictive value of prenatal US detection of complex CHD before and after the introduction of a novel prenatal screening protocol...

Heart failure is a major health problem linked to poor quality of life and high mortality rates. Hence, novel biomarkers, such as fetal marker genes with low expression levels, could potentially differentiate disease states in order to improve therapy. In many studies on heart failure, cardiac biopsies have been analyzed as uniform pieces of tissue with bulk techniques, but this homogenization approach can mask medically relevant phenotypes occurring only in isolated parts of the tissue. This study examines such spatial variations within and between regions of cardiac biopsies...

Rationale: Although mitochondrial diseases often cause abnormal myocardial development, the mechanisms by which mitochondria influence heart growth and function are poorly understood. Objective: To investigate these disease mechanisms, we studied a genetic model of mitochondrial dysfunction caused by inactivation of Tfam (Transcription Factor A, Mitochondrial), a nuclear-encoded gene that is essential for mitochondrial gene transcription and mitochondrial DNA replication. Methods and Results:Tfam inactivation by Nkx2...

BACKGROUND: Most infarctions occur in the left anterior descending coronary artery and cause myocardium damage of the left ventricle. Although current pluripotent stem cells (PSCs) and directed cardiac differentiation techniques are able to generate fetal-like human cardiomyocytes, isolation of pure ventricular cardiomyocytes has been challenging. For repairing ventricular damage, we aimed to establish a highly efficient purification system to obtain homogeneous ventricular cardiomyocytes and prepare engineered human ventricular heart muscles in a dish...

PURPOSE: To investigate the relationship between the location of echogenic intracardiac foci (EIFs) and fetal cardiac anomalies in our patient population. METHODS: We performed a retrospective study of the clinical files of fetuses who underwent an echocardiographic examination at our fetal cardiac medical center from August 2010 to August 2016. Fetuses were grouped by EIF location (left ventricle [LV], right ventricle [RV], or bilateral ventricles [BVs]). The maternal age, reason for referral, and cardiac anomalies in the three groups were analyzed...

BACKGROUND: Tenascin-C (TNC) is a highly conserved matricellular protein with a distinct expression pattern during development and disease. Remodeling of the left ventricle (LV) in response to pressure overload leads to the re-expression of the fetal gene program. OBJECTIVES: The aim of this study was to investigate the function of TNC in cardiac hypertrophy in response to pressure overload. METHODS: Pressure overload was induced in TNC knockout and wild-type mice by constricting their abdominal aorta or by infusion of angiotensin II...

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: 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 colocalize 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...

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...

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...

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...

The majority of female patients with congenital heart disease (CHD) survives into childbearing age and require evidence-based counseling regarding pregnancy options. Even though most of them will have an uneventful pregnancy, they may be at high risk of cardiac, obstetric, and fetal complications. Predictive factors for these complications have been previously identified in numerous studies and with the use of specific scores [CARdiac disease in PREGnancy, Zwangerschap bij Aangeboren HARtAfwijkingen, and World Health Organization (WHO) risk stratification...

Evin Yucel, Doreen DeFaria Yeh
Advances in cardiac surgical interventions in infancy and childhood have led to an increased number of women with congenital heart disease of childbearing age. For these women, individualized preconception counseling and pregnancy planning should be a vital component of their medical management, and presentation for obstetric care may even be an opportunity to re-establish cardiovascular care for patients who have been lost to follow-up. These patients have unique cardiovascular anatomy and physiology, which is dependent upon the surgical intervention they may have undergone during childhood or adolescence...
