OBJECTIVES: To determine cardiac and fetal/neonatal event rates among pregnant women with premature ventricular contractions (PVCs) and compare with control groups. METHODS: Prospective case-control cohort study: 53 consecutive pregnancies in 49 women referred to the St. Paul's Hospital between 2010 and 2016 with PVC burden >1% in women without underlying cardiac disease. Maternal cardiac and fetal/neonatal outcomes were compared with two pregnant control groups: (1) supraventricular tachycardia (SVT) group of 53 women referred for a history of SVT/SVT in the current pregnancy and (2) low-risk group of 53 women with no cardiac disease...

BACKGROUND AND OBJECTIVE: Cardiotocography (CTG), consisting in the simultaneous recording of fetal heart rate (FHR) and maternal uterine contractions (UC), is a popular clinical test to assess fetal health status. Typically, CTG machines provide paper reports that are visually interpreted by clinicians. Consequently, visual CTG interpretation depends on clinician's experience and has a poor reproducibility. The lack of databases containing digital CTG signals has limited number and importance of retrospective studies finalized to set up procedures for automatic CTG analysis that could contrast visual CTG interpretation subjectivity...

BACKGROUND: Intrapartum electronic fetal monitoring (EFM) is the most commonly used tool in obstetrics in the United States, however, which EFM patterns predict acidemia remains unclear. OBJECTIVE: This study was designed to describe the frequency of patterns seen in labor using modern nomenclature, and to test the hypothesis that visually interpreted patterns are associated with acidemia and morbidities in term infants. We further identified patterns prior to delivery, alone or in combination, predictive of acidemia and neonatal morbidity...

Dengue virus (DENV) and chikungunya virus (CHIKV) are transmitted by the same mosquito vectors and now co-circulate in many parts of the world; however, coinfections and serial infections are not often diagnosed or reported. A 38-week pregnant woman was admitted to the hospital with a diagnosis of suspected DENV and CHIKV in southern coastal Ecuador. The pregnancy was complicated by mild polyhydramnios and fetal tachycardia, and a healthy newborn was born. The patient was positive for a recent secondary DENV infection (Immunoglobulin M and Immunoglobulin G positive) and an acute CHIKV infection (real-time reverse transcriptase polymerase chain reaction positive) (Asian genotype)...

BACKGROUND: In pregnant women with Graves' disease, maternal thyrotropin receptor antibodies (TRAb) can cross the placenta and induce fetal or neonatal thyrotoxicosis. Symptoms of fetal thyrotoxicosis are tachycardia, intrauterine growth restriction and intra-uterine death. Recommendations on an upper limit of TRAb concentrations below which intensive fetal monitoring can be safely omitted vary between different guidelines. The objective of this study was to define an evidence-based cut-off level for maternal TRAb necessitating additional fetal monitoring during pregnancy...

Hypoxia-ischemia (HI) is a major contributor to preterm brain injury, but there are currently no reliable biomarkers to identify at risk infants. We tested the hypothesis that fetal heart rate (FHR) and FHR variability (FHRV) would identify evolving brain injury after HI. Fetal sheep at 0.7 of gestation were subjected to either 15 (15-min, n = 10) or 25 min (25-min, n = 17) of complete umbilical cord occlusion or sham occlusion (n = 12). FHR and four measures of FHRV (STV, LTV, SDNN, RMSSD) were assessed until 72 h after HI...

BACKGROUND: There is no consensus on the most effective and best tolerated first-line antiarrhythmic treatment for fetal tachyarrhythmia. The purpose of this systematic review and meta-analysis was to compare the efficacy, safety, and fetal-maternal tolerance of first-line monotherapies for fetal supraventricular tachycardia and atrial flutter. METHODS AND RESULTS: A comprehensive search of several databases was conducted through January 2017. Only studies that made a direct comparison between first-line treatments of fetal tachyarrhythmia were included...

The occurrence of a maternal and fetal tachyarrhythmia together in pregnancy is exceedingly rare. We report a case of a persistent fetal atrial ectopic tachycardia occurring in conjunction with a maternal atrial tachycardia with left ventricular systolic dysfunction. Amiodarone was effective in treating both maternal and fetal arrhythmias.

OBJECTIVE: We hypothesize that routine daily transtelephonic monitoring (TTM) transmissions can accurately detect supraventricular tachycardia (SVT) in asymptomatic infants and/or assuage parental concerns rather than being used solely to diagnose arrhythmias. STUDY DESIGN: Single center, retrospective chart review of 60 patients with fetal or infant SVT prescribed TTM for at least 30 days, January 2010-September 2016. Patients were excluded if initial SVT was not documented, was perioperative, was atrial flutter/fibrillation, or chaotic atrial tachycardia...

OBJECTIVE: To our knowledge, the largest prospective study to report maternal heart rate (MHR) levels in laboring women is 30 patients, and maternal tachycardia is a risk for potential fetal monitoring confusion. Our objective was to analyze a large population of contiguous laboring patients and assess MHR levels attained during the second stage. METHODS: We performed a prospective study that analyzed MHR levels of second stage laboring patients evaluating numerous predisposing maternal conditions...

BACKGROUND: Pregnancies in women with pre-existing cardiomyopathies are considered at high risk for complications. However, few data are available to characterize their natural history and predict the outcome. AIMS: Our aim was to evaluate the prevalence and predictors of acute cardiac and obstetric events in women with a cardiomyopathy during pregnancy, excluding peripartum cardiomyopathy. METHODS: In this retrospective study in a referral centre for cardiomyopathies, we included 43 consecutive pregnancies in 36 women with dilated, hypertrophic, arrhythmogenic right ventricular or tachycardia-induced cardiomyopathy, or left ventricular non-compaction...

Cardiotocography (CTG) is the most commonly used test for establishing the good health of the fetus during pregnancy and labor. CTG consists in the recording of fetal heart rate (FHR; bpm) and maternal uterine contractions (UC; mmHg). FHR is characterized by baseline, baseline variability, tachycardia, bradycardia, acceleration and decelerations. Instead, UC signal is characterized by presence of contractions and contractions period. Such parameters are usually evaluated by visual inspection. However, visual analysis of CTG recordings has a well-demonstrated poor reproducibility, due to the complexity of physiological phenomena affecting fetal heart rhythm and being related to clinician's experience...

BACKGROUND: Non-compaction cardiomyopathy (NCCM) is characterized by prominent trabeculations, deep intertrabecular recesses, and a thick non-compacted endocardial myocardium. Prevalence in the general population remains unclear, but echocardiography series report 0.05%. During fetal development muscle fibers and trabeculae should compact into a solid myocardium and when this fails, NCCM occurs. The condition is genetic, even though acquired forms have been described. Worsening myocardial dysfunction may lead to heart failure and/or arrhythmias...

INTRODUCTION: Several retrospective or single-centre studies demonstrated the efficacy of transplacental treatment of fetal tachyarrhythmias. Our retrospective nationwide survey showed that the fetal therapy will be successful at an overall rate of 90%. For fetuses with hydrops, the treatment success rate will be 80%. However, standard protocol has not been established. The objective of this study is to evaluate the efficacy and safety of the protocol-defined transplacental treatment of fetal tachyarrhythmias...

INTRODUCTION: Instrumental vaginal delivery (IVD) helps expedite delivery during second stage of labour so as to avoid a second stage caesarean section. However, due to mechanical effects on the fetal head, vacuum and forceps may cause cardiotocograph (CTG) abnormalities due to vigal stimulation as well as increased intracranial pressure. OBJECTIVE: To determine the features observed on the CTG during IVD in term pregnancy and correlate them to perinatal outcomes...

OBJECTIVE: Multiple transplacental medications can be used to treat fetal tachycardia. We sought to perform a systematic review and meta-analysis to determine whether digoxin, flecainide or sotalol was the most efficacious therapy for converting fetal tachycardia to sinus rhythm. METHOD: We performed a systematic review and meta-analysis to compare digoxin, flecainide or sotalol as first-line therapy for fetal tachycardia. Studies were identified by a search of PubMed (Medline), Web of Science, and Scopus...
