Emerging evidence demonstrates that heart disease may originate during fetal development. This review will focus on the role of maternal nutrition in the development of the fetal cardiovascular system. Emphasis will be placed upon the concept that nutritional inadequacies during gestation may be major programming stimuli that alter fetal cardiac, ...

To determine the prevalence of 1st and 2nd degree AV block in fetuses with an irregular cardiac rhythm, and to summarize outcome of these pregnancies. The diagnosis of irregular cardiac rhythm or 'skipped beats' includes isolated ectopy that resolves spontaneously. Recently, Doppler measurements of the 'mechanical' PR interval have been ...

As increasing numbers of children with congenital heart disorders reach adulthood, the family physician, cardiologist, and obstetrician will increasingly be called upon to give advice regarding the safety of pregnancy. This need has been further highlighted by the recognition that maternal mortality associated with cardiac disease is rising. Unfortunately, this ...

Cardiac disease complicates approximately 1% to 3% of pregnancies and is responsible for 10% to 15% of maternal mortality. The number of women of childbearing age with congenital disease is increasing as advances in diagnosis and treatment improve survival rates and overall health, allowing successful pregnancy. Pregnant women with severe ...

A ruptured sinus of Valsalva aneurysm is a rare cardiac anomaly, usually of a congenital nature. There are few documented cases of this condition during pregnancy, which renders unclear the therapeutic options. We report the case of a 35-year-old pregnant woman who presented at the hospital for cardiac evaluation due ...

Beta-thalassemia major is a severe, transfusion-dependent anemia that also causes infertility due to iron deposition to endocrine organs after overtransfusion. Very few pregnancies have been reported among such patients after modern therapies. In this study, 32 women with thalassemia who were admitted to Ali Asghar Children's Hospital and Thalassemia Clinic ...

Listeria monocytogenes is an alimentary infection which can be extremely dangerous for pregnant women. A 34-year-old pregnant woman was hospitalized with fetal cardiac rate alterations and influenza-like symptoms. A caesarean section due to fetal distress was performed. A maternal-fetal listeriosis diagnosis was possible only after the birth through bacteriological and ...

BACKGROUND: Foetal echocardiography has become a diagnostic method to detect foetal congenital heart disease with high probability. However, it is not only time consuming and but also difficult to visualize outflow tract of foetus early in the second trimester of pregnancy, even for an experienced obstetric ultrasonographer. Recently, many methods ...

We present a case of fetal tricuspid valve dysplasia, which was diagnosed at 22 weeks of gestation during a routine obstetrical examination. Serial fetal echocardiographic evaluation revealed progressive right ventricular outflow tract obstruction and persistent cardiomegaly. A female infant weighing 1,916 g was delivered by elective cesarean section at 38 ...

OBJECTIVES: To avoid the fetal and maternal risks associated with anticoagulant therapy during pregnancy, the use of bioprostheses has been advocated for young women with cardiac valve disease during the childbearing years. Several reports have suggested the probability of pregnancy-related accelerated structural valve deterioration (SVD). The aim of this study ...

Gravid patient cardiopulmonary bypass remains a high-risk procedure with regard to fetal preservation. Maternal mortality is similar to that of the nonpregnant female at 1.5-5%. However, fetal mortality remains high at 16-33%, with an average of 19% over the past 25 years, with no correlation to gestational age. Teratogenesis is ...

The increased experience in interpretation of fetal echocardiographic images may change the accuracy of fetal echocardiography in diagnosing fetal heart defects. We thus decided to evaluate the specificity and the sensitivity of our fetal echocardiographic examinations in diagnosing congenital heart disease, focusing especially on the outcome of complex cardiac pathologies. ...

Improvements in the diagnosis of congenital malformations explain the increasing early termination of pregnancies. Before 13 weeks of gestation, an accurate in vivo anatomic diagnosis cannot currently be made in all fetuses with current imaging instrumentation. Anatomopathologic examinations remain the gold standard to make accurate diagnoses, although they reach limits ...

During pregnancy, the heart develops a reversible physiological hypertrophic growth in response to mechanical stress and increased cardiac output; however, underlying molecular mechanisms remain unknown. Here, we investigated pregnancy-related changes in heart structure, function, and gene expression of known markers of pathological hypertrophy and cell stretching in mice hearts. In ...

Congenital heart disease is now more prevalent than acquired in pregnancy in the developed world. In pregnancy the fall in systemic vascular resistance and increase in blood volume and cardiac output can cause functional deterioration in certain conditions. A minimally symptomatic woman with good ventricular function, normal oxygen saturation, and ...

Fetal magnetocardiography (fMCG) provides fetal cardiac traces useful for the prenatal monitoring of fetal heart function. In this paper, we describe an analytical model (ACWD) for the automatic detection of cardiac waves boundaries that works on fetal signals reconstructed from fMCG by means of independent component analysis. ACWD was validated ...

BACKGROUND: Cardiomyopathy associated with pregnancy was first described more than half a century ago. However, because of its rare occurrence and geographical differences, the clinical profile of this condition has remained incompletely defined. METHODS AND RESULTS: Data obtained from 123 women with a history of cardiomyopathy diagnosed during pregnancy or ...

Aortic dissection (AD) is an uncommon condition that occurs mainly in the older patient population (>40 years). It is rare in younger people and is usually associated with trauma, Marfan's syndrome, or pregnancy. We report a case of a young weightlifter who died from an AD, and upon autopsy, was ...

Physiological fetal circulation requires patency of the ductus arteriosus. As gestation proceeds, the sensitivity of the ductus to dilating prostaglandins diminishes. The sensitivity to constricting agents like PGE-synthetase inhibitors, present in many analgetics, however, increases. Fetuses affected by an antenatal constriction of the ductus arteriosus (DC) may present with different ...
