Guangzhi Chen, Ge Sun, Renfan Xu, Xiaomei Chen, Li Yang, Yang Bai, Shanshan Yang, Ping Guo, Yan Zhang, Chunxia Zhao, Dao Wen Wang, Yan Wang
BACKGROUND: Cardiac arrhythmias can occur during pregnancy. Owing to radiation exposure and other uncertain risks for the mother and fetus, catheter ablation has rarely been performed and is often delayed until the postpartum period. We reported 2 pregnant women who were experiencing severe arrhythmias and were successfully ablated without fluoroscopic guidance. We also carried out a literature review of cases of pregnant women who underwent zero-fluoroscopy ablation. METHODS AND RESULTS: One woman had drug-resistant and poorly tolerated frequent premature ventricular contraction (PVC) and ventricular tachycardia (VT)...

PURPOSE: Pregnancy increases stress on the circulation of parturient with mitral stenosis secondary to rheumatic heart disease and increases the risk of peripartum heart failure, especially during delivery. This study investigated the epidural anesthesia management for cesarean section in pregnant women with rheumatic heart disease and mitral stenosis. METHODS: 48 parturients with rheumatic heart disease and mitral stenosis that had cesarean section deliveries with epidural anesthesia in the Union Hospital, Fujian Medical University (Fuzhou, China) from Jan 2002 to Dec 2012 were retrospectively analyzed...

BACKGROUND: The aim of this study was to evaluate left ventricular function in preterm infants from 28 days to near term using echocardiography. METHODS: Thirty clinically stable preterm infants delivered at <30 weeks' gestational age were prospectively enrolled. At 28 days, conventional, tissue Doppler, and speckle-tracking echocardiography evaluations of left ventricular function were performed, with comparison made to findings in 30 healthy term infants of similar postnatal age...

The uterus and heart share the important physiological feature whereby contractile activation of the muscle tissue is regulated by the generation of periodic, spontaneous electrical action potentials (APs). Preterm birth arising from premature uterine contractions is a major complication of pregnancy and there remains a need to pursue avenues of research that facilitate the use of drugs, tocolytics, to limit these inappropriate contractions without deleterious actions on cardiac electrical excitation. A novel approach is to make use of mathematical models of uterine and cardiac APs, which incorporate many ionic currents contributing to the AP forms, and test the cell-specific responses to interventions...

OBJECTIVE: Congenital ventricular wall defects are very rare and include congenital ventricular aneurysms (CVAs) and diverticula (CVDs). METHOD: We report a series of five fetuses: three with CVAs and two with CVDs referred due to fetal arrhythmia. In addition to routine fetal echocardiography, fetal magnetocardiography (fMCG) was used. The literature in CVA and CVD is reviewed. RESULTS: Incessant premature ventricular contractions (PVC), mainly bigeminy and trigeminy were found in three fetuses with CVAs and in one with CVD, who also had ventricular couplets...

Medium-chain acyl-coenzyme A dehydrogenase (MCAD) deficiency is the most common disorder of mitochondrial fatty acid oxidation. We report a term male infant who presented at 3 days of age with hypoglycemia, compensated metabolic acidosis, hypocalcemia, and prolonged QTc interval. Pregnancy was complicated by maternal premature atrial contractions and premature ventricular contractions. Prolongation of the QTc interval resolved after correction of metabolic derangements. The newborn screen was suggestive for MCAD deficiency, a diagnosis that was confirmed on genetic analysis that showed homozygosity for the disease-associated missense A985G mutation in the ACADM gene...

OBJECTIVE: To distinguish between blocked atrial bigeminy (BB) and incomplete atrioventricular block with 2:1 conduction (2:1 AVB) can be very difficult, especially in the mid-term fetus. Making a correct diagnosis has important clinical implications, as their prognosis and management differ markedly. Our objective was to investigate whether analysis of isovolumetric time intervals could improve Doppler echocardiography in differentiating these conditions. METHODS: Sixteen fetuses with sustained BB or isolated 2:1 AVB, diagnosed at our tertiary center from 2002 to 2012, were reviewed retrospectively...

Fetal growth restriction and preeclampsia are both conditions of placental etiology and associated to increased risk for the long-term development of cardiovascular disease in the mother. At presentation, preeclampsia is associated with maternal global diastolic dysfunction, which is determined, at least in part, by increased afterload and myocardial stiffness. The aim of this study is to test the hypothesis that women with normotensive fetal growth-restricted pregnancies also exhibit global diastolic dysfunction...

INTRODUCTION: Neostigmine is a frequently used acetylcholinesterase inhibitor administered to reverse muscular relaxation caused by nondepolarizing neuromuscular relaxants in patients recovering from general anesthesia. Severe allergic reactions and urticaria are rarely reported following the use of neostigmine bromide, and never with methylsulfate-containing drugs. In this case, bigeminal premature ventricular contractions added to urticaria provides a warning about the possibility of a life-threatening situation...

AIMS: Congenital heart defects are the most common fetal structural anomalies of which a significant number remain unrecognized during postnatal life. Fetal electrocardiography (FECG) is an ideal clinical tool to complement ultrasonography for the screening and management of these cases where early and accurate diagnoses would allow definite rather than palliative treatment. The objective of this report was to correlate the particular FECG results found with the different types of congenital heart defects involved and to further demonstrate the usefulness of FECG in clinical settings...

OBJECTIVE: The purpose of this study was to assess myocardial function of fetuses who were exposed to intraamniotic infection compared with fetuses of uncomplicated pregnancies by the application of tissue Doppler and strain rate (SR) imaging. STUDY DESIGN: We evaluated the right ventricular function of fetuses with preterm premature rupture of membranes and proven intraamniotic infection (n = 12 fetuses) and healthy fetuses (n = 27). Tissue Doppler velocities during early diastolic relaxation (E(m)) and atrial contraction (A(m)) and early diastolic SR were measured as indices of diastolic function, whereas the peak systolic strain and SR were used as parameters of systolic function...

Although recent studies have demonstrated prenatal nicotine can increase cardiovascular risk in the offspring, it is unknown whether exposure to nicotine during pregnancy also may be a risk for development of arrhythmia in the offspring. In addition, in previous studies of fetal arrhythmia affected by smoking, only two patterns, bradycardia and tachycardia, were observed. The present study examined acute effects of maternal nicotine on the fetal arrhythmia in utero, and chronic influence on offspring arrhythmia at adult stage following prenatal exposure to nicotine...

Abnormal cardiac repolarization renders the heart susceptible to lethal ventricular tachyarrhythmias, increasing the risk of sudden cardiac death in all ages; however, little is known about the incidence and etiology of T-wave abnormalities in utero. In this study, magnetocardiography was used to better define fetal T-wave characteristics, including the QT interval in the normal fetus, and to characterize T-wave abnormalities in the fetus with arrhythmia. The QT interval and T-wave alternans were assessed from magnetocardiographic recordings obtained at 14 to 39 weeks' gestation from 120 fetuses...

BACKGROUND: Preterm premature rupture of membranes (PROM) is associated with one-third of preterm births. In about 50% of preterm PROM cases, the fetuses will elicit a fetal inflammatory response syndrome (FIRS). FIRS is associated with the impending onset of preterm labor, periventricular leukomalacia, neonatal sepsis, and long-term handicap, including the development of bronchopulmonary dysplasia and cerebral palsy. The fetal myocardium is a potential target organ of proinflammatory cytokines released during FIRS...

The characteristics and underlying mechanisms of new-onset ventricular arrhythmia during pregnancy have not been adequately investigated. We studied 11 pregnant women aged 35.4 +/- 3.1 years who experienced new-onset ventricular arrhythmias during pregnancy. The onset of their first episode of ventricular arrhythmia was distributed equally over the 3 trimesters. Ventricular premature contractions (VPCs) and ventricular tachycardia (VT) exhibited a monomorphic configuration in all patients; in 8 (73%) they originated from the right ventricular outflow tract...
