Congenital heart disease pregnancy

INTRODUCTION: Maternal diabetes is a recognized risk factor for both short-term and long-term complications in offspring. Beyond the direct teratogenicity of maternal diabetes, the intrauterine environment can influence the offspring's cardiovascular health. Abnormalities in the cardiac sympathetic system are implicated in conditions such as sudden infant death syndrome, cardiac arrhythmic death, heart failure, and certain congenital heart defects in children from diabetic pregnancies...

High-risk congenital heart disease (CHD) in pregnancy presents a complex clinical challenge. With improved medical care and increased survival rates, a growing population of adults with complex CHD are surviving to adulthood, including women of reproductive age. This chapter focuses on risk stratification and management of pregnant women with high-risk CHD, emphasizing the importance of considering both anatomical and physiological complexity. Maternal physiological changes, such as blood volume increase, cardiac output changes, and alterations in vascular resistance, can significantly impact high-risk CHD patients...

Cardiovascular disease significantly jeopardizes pregnancies in the United States, impacting 1% to 4% of pregnancies annually. Among complications, cardiac arrhythmias are prevalent, posing concerns for maternal and fetal health. The incidence of arrhythmias during pregnancy is rising, partly due to advances in congenital heart surgery and a growing population of women with structural heart disease. While most arrhythmias are benign, the increasing prevalence of more serious arrhythmias warrants a proactive approach...

OBJECTIVE: To determine the live born prenatal detection rate of significant congenital heart disease (CHD) in a large, integrated, multi-center community-based health system using a strategy of referral only of patients with significant cardiac abnormalities on obstetrical screening ultrasound for fetal echocardiography. Detection rates were assessed for screening in both radiology and maternal fetal medicine (MFM). The impact on fetal echocardiography utilization was also assessed. METHODS: This was a retrospective cohort study using an electronic health record, outside claims databases and chart review to determine all live births between 2016 and 2020 with postnatally confirmed sCHD that were prenatally detectable and resulted in cardiac surgery, intervention, or death within 1 year...

BACKGROUND: The increasing and potentially preventable cardiac events in pregnant patients have led to calls to enhance multidisciplinary cardio-obstetrics education. To design a multidisciplinary cardio-obstetrics curriculum for general cardiology and obstetrics and gynecology (OBGYN) residents, we need to define educational needs from the perspectives of both cardiology and OBGYN residents. Our study characterizes the educational needs of Canadian cardiology and OBGYN residents. METHODS: Canadian cardiology and OBGYN residents were surveyed on clinical exposures, perceived needs for topics, unperceived needs for topics (multiple-choice questions) and preferences for educational formats...

BACKGROUND: We evaluated the outcomes of pregnancy in women with congenital heart disease (CHD) and their offspring in Taiwan. We also investigated how different severity levels may influence the outcomes. METHODS: We used data (2009-2017) from the Birth Certificate Application database in Taiwan, which is linked to the National Health Insurance Research Database and Taiwan Maternal and Child Health Database. We identified 2990 women with CHD who had 4227 births...

OBJECTIVE: Kleefstra syndrome (KS), formerly known as 9q subtelomeric deletion syndrome, is characterized by multiple structural abnormalities. However, most fetuses do not have obvious abnormal phenotypes. In this study, the fetus with KS presented with multiple system structural anomalies, and we aimed to explore the genotype-phenotype correlations of KS fetuses. CASE REPORT: Multiple systematic structural anomalies, including severe intrauterine growth restriction (IUGR) and cardiac defects, were detected by ultrasound in the fetus at 33 + 5 weeks' gestation...

OBJECTIVE: To investigate the time to first childbirth and to compare the prevalence of assisted reproductive treatment (ART) in women with congenital heart disease (CHD) compared with women without CHD. METHODS: All women in the national register for CHD who had a registered first childbirth in the Swedish Pregnancy Register between 2014 and 2019 were identified. These individuals (cases) were matched by birth year and municipality to women without CHD (controls) in a 1:5 ratio...

PURPOSE: To evaluate a cohort of fetuses with congenital heart disease (CHD) who underwent serial umbilical artery (UA) Doppler surveillance and assess perinatal outcome according to UA Doppler assessment. METHODS: A retrospective cohort study of singleton fetuses with CHD at a single academic center was performed between 2018 and 2020. Fetuses with a chromosomal abnormality or growth restriction were excluded. We compared fetuses with normal versus abnormal UA Doppler assessment at any time in pregnancy...

BACKGROUND: There is little information of progestogen-only contraceptives in patients with congenital heart disease (CHD) on the long-term. OBJECTIVE: To evaluate the use of contraception in patients with CHD. We studied both short-acting reversible contraceptives (SARCs), oral progestin-only pills (POPs) and long-acting reversible contraceptives (LARCs): intrauterine devices (IUD-IPs) and subdermal implants both impregnated with progestogens (SI-IPs). STUDY DESIGN: Retrospective study of all women attending the preconception clinic...

OBJECTIVE: To examine the association between prenatal cannabis use and structural birth defects in exposed offspring. METHODS: In line with the preregistered protocol (PROSPERO: CRD42022368623), we systematically searched PubMed/Medline, CINHAL, EMBASE, Web of Science, ProQuest, Psych-Info, and Google Scholar for published articles until 25 January 2024. The methodological quality of the included studies was appraised by the Newcastle-Ottawa Quality Assessment Scale (NOS)...

BACKGROUND: We sought to examine pregnancy outcomes in patients with congenital heart disease (CHD) before and after the establishment of formal Cardio-Obstetrics collaboration between adult CHD and Maternal Fetal Medicine (MFM) programs. METHODS: We conducted a retrospective cohort study of pregnant CHD patients from 2002-2020 at a single urban academic institution in the US. We included patients with a singleton gestation who continued a pregnancy beyond 20 weeks...

BACKGROUND: The United States has seen a significant rise in maternal mortality and morbidity associated with cardiovascular disease over the past four decades. Contributing factors may include an increasing number of parturients with comorbid conditions, a higher rate of pregnancy among women of advanced maternal age, and more patients with congenital heart disease surviving into childbearing age and experiencing pregnancy. In response, national medical organizations have recommended the creation of multidisciplinary obstetric-cardiac teams, also known as pregnancy heart teams, to provide comprehensive preconception counseling and coordinated pregnancy management extending through the postpartum period...

BACKGROUND: Congenital and acquired heart disease complicate 1-4% of pregnancies in the United States. Beyond the risks of the underlying maternal congenital heart disease, cardiac surgery and its sequelae, such as surgical scarring resulting in higher rates of arrhythmias and implanted valves altering anticoagulation status, have potential implications that could affect gestation and delivery. OBJECTIVE: To investigate whether history of maternal cardiac surgery is associated with adverse obstetrical or neonatal outcomes when compared to patients without a history of cardiac disease or surgery, considered "healthy controls"...

BACKGROUND: Neonates with congenital heart disease are at risk for impaired brain development in utero, predisposing children to postnatal brain injury and adverse long-term neurodevelopmental outcomes. Given the vital role of the placenta in fetal growth, we assessed the incidence of placental pathology in fetal congenital heart disease and explored its association with total and regional brain volumes, gyrification, and brain injury after birth. METHODS AND RESULTS: Placentas from 96 term singleton pregnancies with severe fetal congenital heart disease were prospectively analyzed for macroscopic and microscopic pathology...

BACKGROUND: Necrotizing enterocolitis (NEC) is a multifactorial gastrointestinal disease with high morbidity and mortality among premature infants. However, studies with large samples on the factors of NEC in China have not been reported. This meta-analysis aims to systematically review the literature to explore the influencing factors of necrotizing enterocolitis in premature infants in China and provide a reference for the prevention of NEC. METHODS: PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (CBM), Wanfang and VIP databases were systematically searched from inception to February 2023...

Advances in cardiology have led to improved survival among patients with congenital heart disease (CHD). Racial disparities in cardiovascular and maternal outcomes are well known and are likely to be more profound among pregnant women with CHD. Using the 2001 to 2018 National Inpatient Sample, we identified all hospitalizations for delivery among women ≥ 18 years of age with CHD. Unadjusted and adjusted between-race differences in adverse maternal cardiovascular, obstetric, and fetal events were assessed using logistic regression models...

Fetal arrhythmias are rare and carry significant morbidity and mortality without appropriate treatment. Initial reports exist of fetal arrhythmia in the setting of maternal COVID-19 infection. Our study sought to evaluate incidence of fetal arrhythmia before and during the COVID-19 pandemic at our institution. This retrospective cohort study from a tertiary care fetal cardiac center utilized the institutional REDCap database to search fetal arrhythmia diagnostic codes. Medical records of mother-fetus dyads were reviewed and data were collected on diagnoses, gestational age, treatment regimen, and postnatal outcomes...

BACKGROUND: The majority of congenital heart diseases (CHDs) are thought to result from the interactions of genetics and the environment factors. This study aimed to assess the association of maternal non-occupational phthalates exposure, metabolic gene polymorphisms and their interactions with risk of CHDs in offspring. METHODS: A multicenter case-control study of 245 mothers with CHDs infants and 268 control mothers of health infant was conducted from six hospitals...
