Fetal cardiac monitoring using noninvasive abdominal leads can provide important information on fetal well-being. However, extraction of fetal electrocardiogram (fECG) from abdominal signals is often problematic because of the higher amplitude maternal ECG (mECG). The aim of this study was to introduce a principal component model for removing the maternal ...

The present article aims to highlight fetal cardiac interventions (FCIs) in terms of indications, strategies, and fetal prognoses. FCIs of the early years were predominantly pharmacological therapies for fetal arrhythmia or heart block. A transplacental transmission of therapeutic agents has now become the main route of pharmacological FCIs. There have ...

Cardiac output (CO) monitoring is helpful in the assessment of critically ill pregnant women, but invasive monitors are often unsuitable for use. We aimed to measure agreement between the non-invasive ultrasound cardiac output monitor (USCOM) and three-dimensional transthoracic echocardiography (3D-TTE) in pregnant women. Healthy pregnant women from 25 weeks gestation ...

Maternal cardiac disease is a major cause of non-obstetric morbidity and accounts for 10-25% of maternal mortality. Valvular heart disease may result from congenital abnormalities or acquired lesions, some of which may involve more than one valve. Maternal and fetal risks in pregnant patients with valve disease vary according to ...

We report a case of a giant placental chorioangioma (15.6 cm diameter) complicated by polyhydramnios and severe fetal heart failure. Fetoscopic laser occlusion of a dominant feeding vessel was performed at 29 weeks' gestation and partial devascularization was achieved. In the 33rd week of the pregnancy, the decision was made to ...

Abstract Objective: We retrospectively compared a protocol using sufentanil and ropivacaine intrathecally with a protocol in which only ropivacaine was administered intrathecally and sufentanil was used epidurally to evaluate whether banning sufentanil from the intrathecal space results in a decreased incidence of adverse fetal heart rate changes. Methods: Some 520 ...

Original interpretations of fetal heart rate (FHR) patterns equated FHR decelerations with 'fetal distress', requiring expeditious delivery. This simplistic interpretation is still implied in our clinical guidelines despite 40 years of increasing understanding of the behaviour and regulation of the fetal cardiovascular system during labour. The physiological basis of FHR responses ...

Aims Detection and careful stratification of fetal heart rate (FHR) is extremely important in all pregnancies. The most lethal cardiac rhythm disturbances occur during apparently normal pregnancies where FHR and rhythm are regular and within normal or low-normal ranges. These hidden depolarization and repolarization abnormalities, associated with genetic ion channelopathies cannot ...

Ultrasonography is a safe and efficient technique for monitoring fetal development and viability. One of the most important and widely used parameters to verify fetal viability is the fetal heart rate (HR). In human medicine, the fetal HR normally oscillates during labor in transient accelerations and decelerations associated with uterine ...

Cardiotocography (CTG) has been recommended for fetal surveillance of high-risk pregnancies in labor in many countries for decades. The test has a high sensitivity, but a low specificity (1), which might have contributed to an increase in cesarean section rate for fetal distress. Therefore, we need a test to identify ...

Abstract Background: Tricuspid regurgitation (TR) is a common sonographic finding during the fetal life. It has been reported in 7% of normal fetuses. It may be associated with aneuploidy and with both cardiac and extracardiac defects. Objectives: In this study, we have looked at the characteristics of fetuses with and ...

Supraventricular tachycardia is relatively uncommon in pregnancy. Symptomatic arrhythmias create challenges in management during pregnancy. Catheter ablation, the usual curative treatment of choice for supraventricular tachycardia, is often deferred as a result of risks of radiation exposure to the developing fetus. Three-dimensional mapping is a new tool in cardiac electrophysiology, ...

In the anomalous fetus, the significance of an abnormal heart rate tracing is not clear because underlying nervous system perturbations may be responsible rather than acidemia. Recently, the National Institute for Child Health and Human Development suggested national nomenclature for fetal heart rate patterns, classified into three categories. The objective ...

Maternal cardiac diseases can be severely compromised in the setting of arrhythmias. We compared perinatal outcomes among women with a cardiac arrhythmia with women with other types of cardiac disease. This is a retrospective cohort study of pregnant women with cardiac disease who delivered from 2008 to 2013. Perinatal outcomes ...

Prostaglandins play a key role in uterine contractions. Term and preterm myometrium has increased expression of prostaglandin receptors. Nonsteroidal anti-inflammatory drugs (NSAIDs) inhibit the cyclooxygenase receptor and thereby decrease uterine contractions during preterm labor. The NSAID indomethacin has been most extensively studied. Its use has been associated with oligohydramnios and ...

Maternal leisure-time physical activity (LTPA) improves cardiac autonomic function in the fetus. The specific physical activity attributes (e.g., mode) that produce this benefit are not well understood. To determine if more time spent performing non-continuous LTPA during pregnancy is significantly associated with lower fetal heart rate (HR) and increased heart ...

Electronic fetal heart rate monitoring is the most common form of intrapartal fetal assessment in the United States. Intermittent auscultation of the fetal heart rate is an acceptable option for low-risk laboring women, yet it is underutilized in the hospital setting. Several expert organizations have proposed the use of intermittent ...
