BACKGROUND: The optimal treatment for fetal supraventricular tachycardia (SVT) with 1:1 atrioventricular relationship is unclear. OBJECTIVE: We compared the effectiveness of transplacental treatment protocols used in 2 centers. METHODS: Pharmacologic treatment was used in 84 fetuses. Maternal oral flecainide was the primary therapy in center 1 (n = 34) and intravenous maternal digoxin in center 2 (n = 50). SVT mechanism was classified by mechanical ventriculoatrial (VA) time intervals as short VA or long VA...

INTRODUCTION: Fetal magnetocardiography (fMCG), the magnetic analog of ECG, has provided invaluable insight into the mechanisms of fetal arrhythmias. In the past 15years, we have evaluated over 300 fetuses with arrhythmia by fMCG. We review the unique characteristics and natural history of the long QT syndrome (LQTS) rhythms. METHODS: We reviewed the fMCGs of subjects referred with suspected LQTS based on either a positive family history or echo diagnosis of the LQTS rhythms (sinus bradycardia, ventricular tachycardia, or 2:1 AV conduction) to the Biomagnetism laboratory in the Department of Medical Physics, UW-Madison...

BACKGROUND: Despite its seldom occurrence, fetal tachycardia can lead to poor fetal outcomes including hydrops and fetal death. Management can be challenging and result in maternal adverse effects secondary to high serum drug levels required to achieve effective transplacental antiarrhythmic drug therapy. CASE: A 33-year-old woman at 33 weeks of gestation with a diagnosis of a fetal sustained superior ventricular tachycardia developed chest pain, shortness of breath, and bigeminy on electrocardiogram secondary to digoxin toxicity despite subtherapeutic serum drug levels...

A 27-week fetus evaluated for bradycardia and hydrops was found to have anti-SSA-negative 2° atrioventricular block and ventricular tachycardia. A presumptive diagnosis of fetal long QT syndrome was made. Transplacental pharmacotherapy with intravenous magnesium and lidocaine restored sinus rhythm. At 30 6/7 weeks, the infant was delivered due to premature labor. Despite postnatal treatment with mexiletine and propranolol, she developed torsades de pointes. Ultimately, a de novo KCNH2 G628S mutation was diagnosed...

Torsion of the pregnant uterus, at term, is a very rare event in obstetric practice. It is associated with high perinatal mortality. We are reporting a case of uterine torsion, where a booked second gravida with previous lower segment cesarean section underwent an emergency cesarean section due to severe lower abdominal pain, persistent fetal tachycardia and poor Bishop Score. Following delivery of baby and placenta, uterus untwisted on itself through 180 degrees and it was realized that the incision had been made on the posterior wall of the uterus...

BACKGROUND: Atrial flutter (AFl) accounts for up to one third of all fetal tachyarrhythmias and can result in premature delivery, hydrops, and fetal death in 10% of cases; however, the electrophysiology of AFl in utero is virtually unstudied. METHODS AND RESULTS: In this observational study, we reviewed 19 fetal magnetocardiography studies from 16 fetuses: 15 fetuses (21-38 weeks' gestation) referred with an echocardiographic diagnosis of AFl and 1 fetus (20 weeks' gestation) referred with a diagnosis of tachycardia that was shown by fetal magnetocardiography to have transient AFl in addition to atrioventricular reciprocating tachycardia...

INTRODUCTION: The aim of this study was to investigate the correlation between increasing time since fetal heart rate (FHR) accelerations, positive (no acceleration) stimulation tests and fetal acidemia. MATERIAL AND METHODS: Observational study of FHR recordings from 1070 laboring women with indication for fetal scalp blood sampling (FBS). FHR traces were scrutinized regarding acceleration at FBS and duration since most recent acceleration. The appraiser was blinded to the FBS result...

INTRODUCTION: Considering maternal complications, it is preferred to induce labour after 40 weeks. Labour induction is a procedure used to stimulate uterine contractions during pregnancy before the beginning of the labour. AIM: The aim of this study was to compare oral misoprostol with vaginal misoprostol for induction of labour in post-term pregnancies. MATERIALS AND METHODS: This double blind clinical-trial study was performed on 180 post-term pregnant women who were admitted to the labour ward of Besat Hospital Sanandaj, Iran in 2013-2014...

Chorioamnionitis is a serious complication during labor at term and is associated with adverse neonatal outcome affecting approximately 10% of pregnancies. It is diagnosed clinically or microbiologically or by histopathologic examination of the placenta and umbilical cord. The clinical criteria for chorioamnionitis found in preterm or term women include maternal fever combined with 2 or more findings of maternal tachycardia, fetal tachycardia, leukocytosis, uterine tenderness, and/or malodorous amniotic fluid...

OBJECTIVES: To determine the basis for the clinical suspicion of fetal distress, the instituted managements and delivery outcome in a tertiary hospital in sub-Saharan Africa with limited capability for advanced fetal monitoring. METHODS: It is a 3 year retrospective analysis of all obstetrics cases with intrapartum fetal distress. RESULTS: There were 301 cases reviewed. The birth asphyxia incidence rate was 233/1000 live births and the perinatal death rate was 47/1000 live births...

BACKGROUND: Most studies comparing phenylephrine and ephedrine have been conducted during elective caesarean sections in healthy mothers with no fetal compromise. The effect of vasopressors on fetal outcome may differ between healthy and compromised fetuses. There has been little research into the effect of phenylephrine and ephedrine, when used for management of post-spinal hypotension in the presence of potential fetal compromise. METHODS: Healthy women with a singleton pregnancy undergoing emergency caesarean section for fetal compromise under spinal anaesthesia were studied...

Fetal arrhythmias are not uncommon in pregnancy. The diagnosis can be established on routine ultrasound scan. Fetal supraventricular tachycardia (SVT) is the most common cause of fetal tachycardia. If left undiagnosed and untreated, these fetuses may develop cardiac failure, hydrops fetalis and eventually death. We report two fetuses diagnosed antenatally to have fetal SVT. Both fetuses were in cardiac failure and were successfully treated with maternal administration of antiarrhythmic medications. Digoxin, and in severe instances, a combination with flecanaide significantly improved fetal outcomes and prevented fetal mortality...

BACKGROUND: Catecholaminergic polymorphic ventricular tachycardia is a genetic disorder in which ventricular tachycardia occurs in the absence of structural heart disease or a prolonged QT interval. If untreated, there is a high incidence of sudden cardiac death. Management of this cardiac condition during pregnancy merits a multidisciplinary approach. CASE: A nulliparous woman with catecholaminergic polymorphic ventricular tachycardia presented at 15 weeks of gestation...

The ductus venosus has a central role in the distribution of highly oxygenated umbilical venous blood to the heart. Its waveform is related to the pressure-volume changes in the cardiac atria and it is therefore important in the monitoring of any fetal condition that may affect forward cardiac function. The cardiovascular parameters that can influence forward cardiac function include afterload, myocardial performance and preload. Decreased forward flow during atrial systole (a-wave) is the most sensitive and ubiquitous finding when any of these parameters is affected...

Umbilical cord hemangiomas are rare, and the natural history is poorly understood. We present a case where the clinical course was complicated by distal umbilical cord edema, episodes of proximal obstruction of umbilical artery blood flow, transient fetal pleural and pericardial effusions, and position-dependent abnormal fetal heart rate monitoring with periods of sustained fetal tachycardia. Delivery was performed for fetal growth restriction with abnormal fetal surveillance. This case highlights possible mechanisms for fetal decompensation as well as the importance of a multifaceted approach to the management of an umbilical cord mass using multiple tools for fetal assessment...
