Symptoms during pregnancy in primiparous women with congenital heart disease

Background: As more women with congenital heart disease (CHD) are reaching childbearing age, it becomes more common for their symptoms to be evaluated during pregnancy. However, pregnancy-related symptoms are similar to those caused by heart disease. This study investigated the prevalence of factors associated with symptoms during pregnancy in women with CHD. Methods: The national birth register was searched for primiparous women with CHD who were registered in the national quality register for patients with CHD. Results: Symptoms during the third trimester were reported in 104 of 465 evaluated women. The most common symptom was palpitations followed by dyspnea. Factors associated with symptoms were tested in a univariable model; higher NYHA classification (>1) (OR 11.3, 95%CI 5.5-23.2), low physical activity (≤3 h/week) (OR 2.1 95%CI 1.3-3.6) and educational level ≤ 12 years (OR 1.9 95%CI 1.2-3.0) were associated with having symptoms. In multivariable analysis, low physical activity level (OR 2.4 95%CI 1.2-5.0) and higher NYHA class (OR 11.3 95%CI 5.0-25.6) remained associated with symptoms during pregnancy. There were no cases with new onset of impaired systemic ventricular function during pregnancy. Conclusion: Symptoms during pregnancy are common in women with CHD but are often already present before pregnancy. Because ordinary symptoms during pregnancy often overlap with symptoms of heart disease, it is important to know if symptoms were present before pregnancy and if they became worse during pregnancy. These results should be included in pre-pregnancy counselling and considered in the monitoring during pregnancy.

Best practice recommendations for medically assisted reproduction in patients with known cardiovascular disease or at high risk of cardiovascular disease

Increasing numbers of people are seeking assisted conception. In people with known cardiac disease or risk factors for cardiac disease, assisted conception may carry increased risks during treatment and any subsequent pregnancy. These risks should be assessed, considered and minimized prior to treatment.

Pregnancy and cardiac maternal outcomes in women with inherited cardiomyopathy: interest of the CARPREG II risk score

AIMS

Inherited cardiomyopathies are relatively rare but carry a high risk of cardiac maternal morbidity and mortality during pregnancy and postpartum. However, data for risk stratification are scarce. The new CARPREG II score improves prediction of prognosis in pregnancies associated with heart disease, though its role in inherited cardiomyopathies is unclear. We aim to describe characteristics and cardiac maternal outcomes in patients with inherited cardiomyopathy during pregnancy, and to evaluate the interest of the CARPREG II risk score in this population.

METHODS AND RESULTS

In this retrospective single-centre study, 90 consecutive pregnancies in 74 patients were included (mean age 32 ± 5 years), including 28 cases of dilated cardiomyopathy (DCM), 46 of hypertrophic cardiomyopathy, 11 of arrhythmogenic right ventricular cardiomyopathy and 5 of left ventricular noncompaction, excluding peripartum cardiomyopathy. The discriminatory power of several risk scores was assessed by the area under the receiver-operating characteristic curve (AUC). Median CARPREG II score was 2 [0;3] and was higher in the DCM subgroup. A severe cardiac maternal complication was observed in 18 (20%) pregnancies, mainly driven by arrhythmia and heart failure (each event in 10 pregnancies), with 3 cardiovascular deaths. Forty-three pregnancies (48%) presented foetal/neonatal complications (18 premature delivery, 3 foetal/neonatal death). CARPREG II was significantly associated with cardiac maternal complications (P < 0.05 for all) and showed a higher AUC (0.782) than CARPREG (0.755), mWHO (0.697) and ZAHARA (0.604).

CONCLUSIONS

Pregnancy in women with inherited cardiomyopathy carries a high risk of maternal cardiovascular complications. CARPREG II is the most efficient predictor of cardiovascular complications in this population.

Clinical Risk Assessment and Prediction in Congenital Heart Disease Across the Lifespan: JACC Scientific Statement

Congenital heart disease (CHD) comprises a range of structural anomalies, each with a unique natural history, evolving treatment strategies, and distinct long-term consequences. Current prediction models are challenged by generalizability, limited validation, and questionable application to extended follow-up periods. In this JACC Scientific Statement, we tackle the difficulty of risk measurement across the lifespan. We appraise current and future risk measurement frameworks and describe domains of risk specific to CHD. Risk of adverse outcomes varies with age, sex, genetics, era, socioeconomic status, behavior, and comorbidities as they evolve through the lifespan and across care settings. Emerging technologies and approaches promise to improve risk assessment, but there is also need for large, longitudinal, representative, prospective CHD cohorts with multidimensional data and consensus-driven methodologies to provide insight into time-varying risk. Communication of risk, particularly with patients and their families, poses a separate and equally important challenge, and best practices are reviewed.

How severity and classification of pulmonary hypertension affect pregnancy outcomes: a systematic review and timeline

Women with pulmonary hypertension (PH) have increased mortality during pregnancy and the peripartum period. An increasing number of publications suggest improvements in maternal outcomes, so we conducted a systematic review focusing on disease severity and maternal survival. After screening 9097 potential studies from 1967 to 2021, we identified 66 relevant publications. Outcomes improved continuously over time and mortality fell from 11.6% in studies published before 2015 to 8.2% in studies published after 2015. Mortality was lower in patients with mild disease (0.8%) than in those with Eisenmenger syndrome (26.2%) or idiopathic pulmonary arterial hypertension (7.4-24.0%). One major drawback of the published studies is that they define severity using echocardiographic-estimated pulmonary artery pressures, without considering more contemporary parameters. This systematic review provides new insights for preconception counseling on pregnancy risks related to PH and suggests that PH classification and severity should be carefully considered in determining an individual's pregnancy-associated risk.

Routine Antenatal Echocardiography in High-Prevalence Areas of Rheumatic Heart Disease: A WHO-Guideline Systematic Review

Background

Rheumatic Heart Disease (RHD) is the most common cause of valvular heart disease worldwide. Undiagnosed or untreated RHD can complicate pregnancy and lead to poor maternal and fetal outcomes and is a significant factor in non-obstetric morbidity. Echocardiography has an emerging role in screening for RHD. We aimed to critically analyse the evidence on the use of echocardiography for screening pregnant women for RHD in high-prevalence areas.

Methods

We searched MEDLINE and Embase to identify the relevant reports. Two independent reviewers assessed the reports against the eligibility criteria in a double-blind process.

Results

The searches (date: 4 April 2023) identified 432 records for screening. Ten non-controlled observational studies were identified, five using portable or handheld echocardiography, comprising data from 23,166 women. Prevalence of RHD varied across the studies, ranging from 0.4 to 6.6% (I2, heterogeneity >90%). Other cardiac abnormalities (e.g., congenital heart disease and left ventricular systolic dysfunction) were also detected <1% to 2% of cases. Certainty of evidence was very low.

Conclusion

Echocardiography as part of antenatal care in high-prevalence areas may detect RHD or other cardiac abnormalities in asymptomatic pregnant women, potentially reducing the rates of disease progression and adverse labor-associated outcomes. However, this evidence is affected by the low certainty of evidence, and lack of studies comparing echocardiography versus standard antenatal care.

Management and outcomes of pregnant women with cardiovascular diseases in a cardio-obstetric team

BACKGROUND

Cardiovascular diseases (CVDs) are currently the leading cause of maternal death in Western countries. Although multidisciplinary cardio-obstetric teams are recommended to improve the management of pregnant women with CVD, data supporting this approach are scarce.

AIMS

To describe the characteristics and outcomes of pregnant patients with CVD managed within the cardio-obstetric programme of a tertiary centre.

METHODS

We included every pregnant patient with history of CVD managed by our cardio-obstetric team between June 2017 and December 2019, and collected all major cardiovascular events (death, heart failure, acute coronary syndromes, stroke, endocarditis and aortic dissection) that occurred during pregnancy, peripartum and the following year.

RESULTS

We included 209 consecutive pregnancies in 202 patients. CVDs were predominantly valvular heart diseases (37.8%), rhythm disorders (26.8%), and adult congenital heart diseases (22.5%). Altogether, 47.4% were classified modified World Health Organization (mWHO)>II, 66.5% had CARdiac disease in PREGnancy score (CARPREG II)≥2 and 80 pregnancies (38.3%) were delivered by caesarean section. Major cardiovascular events occurred in 16 pregnancies (7.7%, 95% confidence interval [CI] 4.5-12.2) during pregnancy and in three others (1.5%, 95% CI 0.3-4.1) during 1-year follow-up. Most events (63.1%) occurred in the 16.3% of patients with unknown CVD before pregnancy.

CONCLUSIONS

The management of pregnant patients with CVD within a cardio-obstetric team seems encouraging as we found a relatively low rate of cardiovascular events compared to the high-risk profile of our population. However, most of the remaining events occurred in patients without cardiac monitoring before pregnancy.

Multidisciplinary care of peripartum heart failure: A scientific statement of the Heart Failure Association of the ESC

Heart failure is the most common cardiovascular complication during pregnancy and the postpartum period. It is associated with increased risk of maternal morbidity and mortality as well as potentially life-threatening foetal pathology. Management of heart failure in pregnancy requires expert knowledge of cardiovascular disease as well as obstetrics which underscores the importance of multidisciplinary cardio-obstetrics teams in order to optimize diagnosis, treatment and outcome. This includes counselling of women at risk before and during the course of pregnancy in order to strengthen the relationship between medical specialists and patients, as well as to allow patient-centred delivery of care and improve quality of life.

[Maternal mortality due to cardiovascular diseases in France 2016-2018]

Between 2016 and 2018, cardiovascular diseases were responsible for 41 deaths, making it the leading cause of maternal death within 42 days postpartum in France. The maternal mortality ratio (MMR) for cardiovascular disease is 1.8 per 100,000 NV, a non-significant increase compared with the 2013-2015 triennium (MMR of 1.5 per 100,000 NV). Deaths from cardiac causes accounted for the majority (n=28), with 26 deaths secondary to cardiac disease aggravated by pregnancy (indirect deaths) and 2 deaths related to peripartum cardiomyopathy (direct deaths). Deaths from vascular causes (n=13) corresponded to 9 aortic dissections and 4 ruptures of large vessels, including 3 ruptures of the splenic artery. Preventability of death (possible or probable) was found in 56% of cases compared with 66% in the previous triennium. Care was considered sub-optimal in 57% of cases, down from 72% in the 2013-2015 triennium. In women with known cardiovascular disease, the areas for improvement concern multidisciplinary follow-up, repeated assessment of the cardiovascular risk (WHO grade) and early referral to an expert centre (expert cardiologists, obstetricians, anaesthetists and intensive care). In all pregnant women or women who have recently given birth, a cardiovascular etiology should be considered in the presence of suggestive symptoms (dyspnea, chest or abdominal pain). Ultrasound "point of care" examination (fluid effusions, cardiac dysfunction) and cardiac enzymes assay can help in the diagnosis. Finally, the woman must be involved in her own care.

Pregnancy-related cardiac outcomes among patients with congenital heart disease after formalization of a cardio-obstetrics program

BACKGROUND

The prevalence of pregnant patients with congenital heart disease (CHD) is increasing, and these patients are at high risk for cardiac morbidity.

OBJECTIVE

This study aimed to examine the pregnancy outcomes in patients with congenital heart disease before and after the establishment of formal cardio-obstetrics collaboration between adult congenital heart disease and maternal-fetal medicine programs.

STUDY DESIGN

This was a retrospective cohort study of pregnant patients with congenital heart disease from 2002 to 2020 at a single urban academic institution in the United States. This study included patients with a singleton pregnancy who continued a pregnancy beyond 20 weeks of gestation. The primary outcome was a composite adverse maternal cardiac outcome, compared before (2002-2010) and after (2011-2020) the program. The secondary outcomes included gestational age at delivery, mode of delivery, rate of labor induction, use of diuresis after delivery, and a composite maternal morbidity outcome.

RESULTS

The number of pregnant patients with congenital heart disease increased after formalization of the cardio-obstetrics program (200 [postprogram group] vs 84 [preprogram group]; 0.48% of all deliveries in the postprogram group vs 0.25% of all deliveries in the preprogram group; P<.001). The postprogram group was more likely to undergo labor induction than the preprogram group (126 [63%] vs 34 [41%], respectively; P<.001). There were fewer patients in the postprogram group than in the preprogram group who were New York Heart Association class II to IV (23 [12%] vs 17 [22%], respectively; P=.04) or with systemic ventricular dysfunction (8 [4%] vs 12 [16%], respectively; P=.001). There was no difference in the primary outcome (38 [19%] in the postprogram group vs 14 [17%] in the preprogram group; P=.64), even after adjusting for confounders, including New York Heart Association class >I and systemic ventricular dysfunction (adjusted odds ratio, 2.3; 95% confidence interval, 0.96-5.4). Patients in the postprogram group were more likely to receive diuresis after delivery than patients in the preprogram group, even in the absence of heart failure or pulmonary edema (9 [4.5%] vs 0 [0.0%], respectively; P=.04).

CONCLUSION

In the period after the establishment of a formal cardio-obstetrics program between adult congenital heart disease and maternal-fetal medicine, the number of patients with congenital heart disease delivering at our institution increased significantly. Overall, fewer patients entered pregnancy with advanced-stage heart failure or systemic ventricular dysfunction, possibly suggesting improved prepregnancy cardiac care or improved preconception counseling. Composite maternal cardiac outcomes were similar, but the rates of postpartum diuresis increased significantly, suggesting increased attention to volume status in the postpartum period. Formalized collaboration between congenital heart disease and maternal-fetal medicine may help better optimize patients' care before conception, during pregnancy, and after delivery.

An Overview of Arrhythmias in Pregnancy

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. Guidance and reassurance suffice in many cases, but persistent symptoms require cautious use of antiarrhythmic drugs or other therapies for a safe outcome. Managing more serious arrhythmias requires a comprehensive, multidisciplinary approach involving specialists, including maternal-fetal medicine physicians, cardiologists, electrophysiologists, and anesthesiologists.

Fetomaternal outcomes in pregnant women with congenital heart disease: a comparative analysis from an apex institute

OBJECTIVE

With advancements in cardiac surgical interventions during infancy and childhood, the incidence of maternal congenital heart disease (CHD) is increasing. This retrospective study compared fetal and cardiac outcomes in women with and without CHD, along with a sub-analysis between cyanotic versus non-cyanotic defects and operated versus non-operated cases.

METHODS

A 10-year data were retrospectively collected from pregnant women with CHD and a 1:1 ratio of pregnant women without any heart disease. Adverse fetal and cardiac outcomes were noted in both groups. Statistical significance was set at P<0.05.

RESULTS

A total of 86 pregnant women with CHD were studied, with atrial septal defects (29.06%) being the most common. Out of 86 participants, 27 (31.39%) had cyanotic CHD. Around 55% of cases were already operated on for their cardiac defects. Among cardiovascular complications, 5.8% suffered from heart failure, 7.0% had pulmonary arterial hypertension, 8.1% presented in New York Heart Association functional class IV, 9.3% had a need for intensive care unit admission, and one experienced maternal mortality. Adverse fetal outcomes, including operative vaginal delivery, mean duration of hospital stay, fetal growth restriction, preterm birth (<37 weeks), low birth weight (<2,500 g), 5-minute APGAR score <7, and neonatal intensive care unit admissions, were significantly higher in women with CHD than in women without heart disease.

CONCLUSION

Women with CHD have a higher risk of adverse fetal and cardiac outcomes. The outcome can be improved with proper pre-conceptional optimization of the cardiac condition, good antenatal care, and multidisciplinary team management.

Aorta pathology and pregnancy-related risks in adult congenital cardiac disease: does the aorta dilate during pregnancy?

Background

Aortic dilatation and pregnancy are major concerns in women with aortopathy (AOP). This single-centre retrospective analysis focuses on the evolution of aortic diameters during and after pregnancy in women with Marfan syndrome (MS), Turner syndrome (TS) and bicuspid aortic valve (BAV) aortopathy.

Methods and results

Thirty-eight women who had one or more single pregnancies were included. The ascending aorta was measured during pregnancy and postpartum. During pregnancy, a significant increase of diameters of the sinus aortae (median 1.4 mm; [-1.3; 3.8]) and ascending aorta (median 2.1 mm; [0.0; 4.0]) was noted. Systemic hypertension gives dilation of the aorta, but it did not influence the overall trajectory during pregnancy.

Conclusion

Significant aortic dilatation is noted during pregnancy in women with underlying AOP, even persisting in the long term. Pre-existing systemic hypertension is associated with larger aortic diameters prior to pregnancy. More research on a larger study population however is needed.

Ischemic heart disease in pregnancy: a practical approach to management

Ischemic heart disease is a crucial issue during pregnancy. The term is composed of both preexisting conditions and acute coronary syndrome in pregnancy, including pregnancy-associated myocardial infarction, which can have a significant effect on maternal and fetal outcomes. This review provides a complete guide to managing ischemic heart disease in pregnant women, emphasizing the importance of multidisciplinary care and individualized treatment strategies. Cardiovascular disease, particularly ischemic heart disease, is now the leading cause of maternal mortality worldwide. Pregnancy introduces unique physiological changes that increase the risk of acute myocardial infarction, with pregnancy-associated myocardial infarction cases often associated with factors, such as advanced maternal age, chronic hypertension, and preexisting cardiovascular conditions. This review distinguishes between preexisting ischemic heart disease and pregnancy-associated myocardial infarction. It will emphasize the various etiologies of pregnancy-associated myocardial infarction, including coronary atherosclerosis and plaque rupture presenting as ST-elevation myocardial infarction, non-ST-elevation myocardial infarction, and other nonatherosclerotic causes, including spontaneous coronary artery dissection, vasospasm, and embolism. Our study discusses the practical management of ischemic heart disease in pregnancy, with a focus on preconception counseling, risk assessment, and tailored antenatal planning for women with preexisting ischemic heart disease. Moreover, this document focuses on the challenges of diagnosing cardiovascular disease, especially when presented with nonclassical risk factors and presentation. It provides insight into the appropriate diagnostic testing methods, such as electrocardiogram, cardiac biomarkers, and echocardiography. In addition, the review covers various treatment strategies, from medical management to more invasive procedures, including coronary angiography, percutaneous coronary intervention, and coronary artery bypass graft. Special attention is given to medication safety during pregnancy, including anticoagulation, beta-blockers, and antiplatelet agents. The complexities of delivery planning in women with ischemic heart disease are discussed, advocating for a multidisciplinary team-based approach and careful consideration of the timing and mode of delivery. Furthermore, the roles of breastfeeding and postpartum care are explored, emphasizing the long-term benefits and the suitability of various medications during lactation. Lastly, this review provides crucial insights into the management of ischemic heart disease in pregnancy, stressing the need for heightened awareness, prompt diagnosis, and tailored management to optimize maternal and fetal health outcomes.

Designing a Multidisciplinary Cardio-obstetrics Curriculum for General Cardiology and Obstetrics Residents: A National Survey of Educational Needs

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. High priorities were defined as ≥ 50% of responses indicating a perceived need or ≥ 50% indicating an unperceived need.

Results

A total of 154 residents participated (cardiology n = 44, OBGYN n = 110). Residents reported insufficient clinical exposure to nearly all cardiac disorders, with 33% of exposures occurring in multidisciplinary contexts. All topics aside from gestational hypertension were rated as high priority on perceived needs by both specialties. High-priority unperceived needs were congenital heart disease (both specialties), pre-existing acquired heart disease (both specialties), medication safety (OBGYN), peripartum management (OBGYN), and pregnancy-related heart disease (OBGYN). Cardiology and OBGYN residents shared preferences for in-person simulation, virtual simulation, and online modules.

Conclusions

Residents in both specialties reported low clinical exposure to most cardiac disorders during pregnancy, identified high-priority perceived needs in multiple topics, and shared 2 high-priority unperceived needs. OBGYN residents identified 3 additional high-priority unperceived needs. These data can inform design of multidisciplinary cardio-obstetrics curricula for general cardiology and OBGYN residents.

Characterization of cardiac arrhythmias and maternal-fetal outcomes in pregnant women: A prospective cohort study

INTRODUCTION AND OBJECTIVES

Cardiovascular disease is a common cause of morbidity and mortality in pregnant women. Arrhythmias are common complications during pregnancy; however, the data are limited. Our goal was to characterize the epidemiology, clinical presentation, and impact of cardiac arrhythmias on maternal-fetal outcomes.

METHODS

A prospective cohort study from the Colombian Registry of Pregnancy and Cardiovascular Disease was carried out from 2016 to 2019. All patients with tachyarrhythmia or bradyarrhythmia and a minimum follow-up of six months after delivery were included. The primary outcome was a composite of cardiac events defined as pulmonary edema, symptomatic sustained arrhythmia requiring specific therapy, stroke, cardiac arrest, or maternal death. Secondary outcomes were other cardiac, neonatal, and obstetric events.

RESULTS

Arrhythmias were the most common cause of referral to our dedicated cardio-obstetric clinic. A total of 92 patients were included, mean age 27±6 years; 8.7% had previous structural heart disease, and cardiology consultation was delayed in 79.4%. The most common arrhythmias were premature ventricular contractions (33%) and paroxysmal reentrant supraventricular tachycardias (15%); 11 patients (12%) had cardiac implantable electronic devices. Cardiac events occurred in 18.4% of patients, obstetric events occurred in 6.5%, and one caesarean was indicated in the context of symptomatic severe mitral stenosis. Adverse neonatal outcomes were observed in 24.3% of newborns.

CONCLUSIONS

Arrhythmias were the most common cause of referral to a dedicated cardio-obstetric clinic; most had a benign course. Adverse maternal cardiovascular outcomes were significant and there was a high rate of obstetric and neonatal adverse events, underlining the importance of multidisciplinary care.

Effects of calcium supplementation on changes in the IL2, IL4, IL6, IL10 axes and oxidative stress in pregnant women at risk for pre-eclampsia

BACKGROUND

Pregnant women with hypertensive disorders are at increased risk for inflammatory diseases and oxidative stress. The dilemma raised by the best dosage of calcium supplementation on these factors is evident. The aim of the current study was to examine the effects of calcium on biomarkers of the purinergic system, inflammation and oxidative stress, which are factors contributing to vascular damage in pregnant women at high risk of pre-eclampsia.

METHODS

A prospective, double-blind and placebo-controlled study conducted with 101 women at risk of pre-eclampsia were randomized to take 500 mg calcium/day or 1,500 mg calcium/day or placebo for 6 weeks from the 20th gestational week until delivery. Fasting blood samples were collected at the beginning of the study and 6 weeks after the intervention.

RESULTS

Taking calcium supplements (500 mg calcium/day) led to a significant increase in ATP hydrolysis (p < 0.05), NTPDase activity with increased hydrolysis of ADP and AMP nucleotides in platelets and lymphocytes. In the intragroup analysis IL-2, IL-6, IL-4 and interferon-ɣ presented lower values in the calcium 1,500 mg/day group (p < 0.005). Oxidative stress was assessed by TBARS pro-oxidant marker, with an increase for the calcium groups when compared to the placebo group. The Vitamin C antioxidant marker presented a significant increase (p < 0.005) for the group that received high calcium doses.

CONCLUSIONS

Calcium administration for 6 weeks had antioxidant action and positively modulated the purinergic system and inflammatory markers in pregnant women at risk of pre-eclampsia.

Postpartum quality of life and mental health in women with heart disease: Integrated clinical communication and treatment

BACKGROUND

Postpartum quality of life (QoL) in women with heart disease has been neglected.

AIM

To improve clinical communication and treatment, we integrated medical data and subjective characteristics to study postpartum QoL concerns.

METHODS

The study assessed QoL 6 wk after birth using the 12-Item Short-Form Health Survey. The Edinburgh Postnatal Depression Scale, Cardiac Anxiety Questionnaire, European Heart Failure Self-Care Behavior Scale, and a self-designed questionnaire based on earlier research were also used to assess patient characteristics. Patient data were collected. Prediction models were created using multiple linear regression.

RESULTS

This retrospective study examined postpartum QoL in 105 cardiac patients. Postpartum QoL scores were lower (90.69 ± 13.82) than those of women without heart disease, with physical component scores (41.09 ± 9.91) lower than mental component scores (49.60 ± 14.87). Postpartum depression (33.3%), moderate anxiety (37.14%), pregnancy concerns (57.14%), offspring heart problems (57.14%), and life expectancy worries (48.6%) were all prevalent. No previous cardiac surgery, multiparity, higher sadness and cardiac anxiety, and fear of unfavorable pregnancy outcomes were strongly related to lower QoL (R2 = 0.525).

CONCLUSION

Postpartum QoL is linked to physical and mental health in women with heart disease. Our study emphasizes the need for healthcare workers to recognize the unique characteristics of these women while developing and implementing comprehensive management approaches during their maternity care.

Age-Stratified Sex Differences in Heart Failure With Preserved Ejection Fraction Among Adult Hospitalizations

BACKGROUND

There is evidence that heart failure with preserved ejection fraction (HFpEF)-related hospitalizations are increasing in the United States. However, there is a lack of knowledge about HFpEF-related hospitalizations among younger adults.

OBJECTIVE

The aims of this study were to perform a retrospective analysis using the Nationwide Inpatient Sample and to examine age-stratified sex differences in the prevalence, correlates, and outcomes of HFpEF-related hospitalization across the adult life span.

METHOD

Using the Nationwide Inpatient Sample (2002-2014), patient and hospital characteristics were determined. Joinpoint regression was used to describe age-stratified sex differences in the annual average percent change of hospitalizations with HFpEF. Survey logistic regression was used to estimate adjusted odds ratios representing the association of sex with HFpEF-related hospitalization and in-hospital mortality.

RESULTS

There were 8 599 717 HFpEF-related hospitalizations (2.43% of all hospitalizations). Women represented the majority (5 459 422 [63.48%]) of HFpEF-related adult hospitalizations, compared with men (3 140 295 [36.52%]). Compared with men younger than 50 years, women within the same age group were 6% to 28% less likely to experience HFpEF-related hospitalization. Comorbidities such as hypertensive heart disease, renal disease, hypertension, obstructive sleep apnea, atrial fibrillation, obesity, anemia, and pulmonary edema explained a greater proportion of the risk of HFpEF-related hospitalization in adults younger than 50 years than in adults 50 years or older.

CONCLUSION

Before the age of 50 years, women exhibit lower HFpEF-related hospitalization than men, a pattern that reverses with advancing age. Understanding and addressing the factors contributing to these sex-specific differences can have several potential implications for improving women's cardiovascular health.

Cardiogenic shock in pregnancy

Cardiac disease complicates 1%-4% of pregnancies globally, with a predominance in low and middle-income countries (LMICs). Increasing maternal age, rates of obesity, cardiovascular comorbidities, pre-eclampsia and gestational diabetes all contribute to acquired cardiovascular disease in pregnancy. Additionally, improved survival in congenital heart disease (CHD) has led to increasing numbers of women with CHD undergoing pregnancy. Implementation of individualised care plans formulated through pre-conception counselling and based on national and international guidance have contributed to improved clinical outcomes. However, there remains a significant proportion of women of reproductive age with no apparent comorbidities or risk factors that develop heart disease during pregnancy, with no indication for pre-conception counselling. The most extreme manifestation of cardiac disease is cardiogenic shock (CS), where the primary cardiac pathology results in inadequate cardiac output and hypoperfusion, and is associated with significant mortality and morbidity. Key to management is early recognition, intervention to treat any potentially reversible underlying pathology and supportive measures, up to and including mechanical circulatory support (MCS). In this narrative review we discuss recent developments in the classification of CS, and how these may be adapted to improve outcomes of pregnant women with, or at risk of developing, this potentially lethal condition.

Care for the Obstetric Patient with Complex Cardiac Disease

The prevalence of cardiac disease-related maternal morbidity and mortality is on the rise in the United States. To ensure safe management of pregnancy in patients with cardiovascular disease, pre-delivery evaluation by a multidisciplinary Pregnancy Heart Team should occur. Appropriate anesthetic, cardiac, and obstetric care are essential. Risk stratification tools evaluate the etiology and severity of cardiovascular disease to determine the appropriate hospital type and location for delivery and anesthetic management. Intrapartum hemodynamic monitoring may need to be intensified, and neuraxial analgesia and anesthesia are generally appropriate. The anesthesiologist must be prepared for obstetric and cardiac emergencies.

Hypertensive Disorders in Pregnancy: Global Burden From 1990 to 2019, Current Research Hotspots and Emerging Trends

Hypertensive disorders in pregnancy (HDP) constitute a worldwide health problem for pregnant women and their infants. This study provided HDP burden over 1990 to 2019 by region and age distribution, and predicted changes in related values for the next 25 years. We then conducted an econometric analysis of the author distribution, collaborative networks, keyword burst clustering, and spatio-temporal analysis of HDP-related publications from 2012 to 2022 to access current scientific developments and hotspots. The number of pregnant women with HDP has been increasing over the past 30 years, with regional and age-stratified differences in the burden of disease. Additionally, projections suggest an increase of deaths due to maternal HDP among adolescents younger than 20 years. Current research is mostly centered on pre-eclampsia, with hot keywords including trophoblast, immune tolerance, frozen-thawed embryo transfer, aspirin, gestational diabetes association, and biomarkers. Researches on the pathological mechanism, classification, and subtypes of HDP need to be further advanced.

Pregnancy outcomes of women with cardiac disease

OBJECTIVE

To determine and predict the maternal and neonatal outcomes of pregnancies occurring in patients with cardiac disease.

METHOD

This retrospective review included 147 pregnancies identified from antenatal, delivery, and nursery records. Information concerning the nature and severity of the pre-existing cardiac disease, comorbidities, risk scores, obstetric or cardiac complications, and pregnancy outcomes were collected. The data were analyzed using SPSS Windows version 22.

RESULTS

In all, 111 (73.5%) of the cohort had acquired heart disease and 4 (2.7%) of patients belonged to WHO class IV, in which pregnancy is not recommended. Additionally, 12 (8.1%) were categorized as being at significant risk of having a cardiac complication. The proportion of patients that had maternal and perinatal mortality was 6 (4.0%) and 7 (4.8%), respectively. The WHO and CARPREG scoring systems were reliably able to predict cardiac events (P < 0.01). Mothers who received preconception counseling had significantly fewer occurrences of cardiac and obstetric events than those who did not.

CONCLUSION

Cardiac disease in pregnancy in women managed at our center was most often an acquired disease. The baseline risk assessment scores accurately predicted the likelihood of adverse cardiac outcomes.

Effects of maternal pulmonary arterial hypertension on fetal hemodynamics and maternal-fetal outcome in late pregnancy

PURPOSE

The aim of this study was to investigate the effects of maternal pulmonary arterial hypertension (PAH) on fetal hemodynamics in the third trimester and to identify hemodynamic indicators associated with adverse maternal and fetal outcomes.

METHODS

We recruited 48 pregnant women with PAH in the third trimester and 32 women with normal pregnancies as controls matched for age and gestational week. Fetal growth and hemodynamic parameters were assessed by two-dimensional and color Doppler. All cases were followed up until delivery and maternal and fetal outcomes were collected. High throughput sequencing method was used to determine differential miRNA patterns in plasma exposed to pulmonary arterial hypertension (PAH) in pregnant women. We then performed the validated of key differentially expressed miRNAs by real-time PCR.

RESULTS

Compared with the normal and mild PAH groups, resistance index (RI), pulsatility index (PI) of the fetal umbilical artery (UA) and quantitative ductus venosus (QDV) blood flow were increased in subjects with moderate to severe PAH, while PI and the ratio of peak systolic velocity (PSV) to end-diastolic velocity (EDV) (S/D) of the middle cerebral artery (MCA) were decreased. Compared with the normal group, subjects in the mild and moderate PAH groups had lower neonatal weight, shorter neonatal height, and higher preterm birth rates. In addition, miRNA sequencing data showed that PAH affected the levels of 23 miRNAs in plasma. At the same time, we showed that PAH significantly decreased the level of miR-1255a and increased the level of miR-548ar-3p by real-time PCR.

CONCLUSION

In the group of pregnant women with moderate to severe pulmonary hypertension, there was a higher proportion of preterm births and low birth weight babies. Hemodynamic changes in the fetal UA, MCA, and ductus venosus (DV) during late pregnancy were associated with adverse fetal outcomes. At the same time, miRNA sequencing results showed that miR-1255a and miR-548ar-3p may play an important role in the development of PAH.

Increased cesarean section rate and premature birth according to modified WHO maternal cardiovascular risk in pregnant women with congenital heart disease

BACKGROUND

During pregnancy and delivery, hemodynamics are altered and complex congenital heart disease has been associated with adverse maternal and neonatal outcomes. We sought to investigate pregnancy outcome and complications in relation to complexity of heart condition.

MATERIALS AND METHODS

We studied women with ACHD discussed at multidisciplinary conferences at Lund University Hospital March 2009-May 2021. We studied 149 pregnancies in 101 women. We scored each woman retrospectively according to the modified World Health Organization (mWHO) risk classification and included patients in risk class I (n = 36, 24.1%), II (n = 43, 28.9%), II-III (n = 43, 28.9%), III (n = 24, 16.1%) and IV (n = 3, 2.0%).

RESULTS

Women with mWHO class ≥III underwent cesarean section more often than women in less complex mWHO classes, (OR, 5.1; 95% CI, 2.0-12.5; p<0.001). The odds of premature delivery were significantly higher among pregnant women with mWHO class ≥III (OR, 6.7; 95% CI, 2.6-17.4; p<0.001). We found no difference in incidence of preeclampsia, gestational hypertension, gestational diabetes, hemorrhage >1000 ml or cardiac defect in the neonate depending on WHO-class. Women in mWHO classes III-IV had a higher rate of fetal growth restriction (FGR) compared to women in mWHO classes I, II, II-III (p<0.007).

CONCLUSIONS

Our findings indicate that women with more complex heart disease (mWHO classes III or IV) tend to have a higher rate of cesarean section, premature birth and FGR.

Cardiovascular Fellowship Training in Cardio-Obstetrics: JACC Review Topic of the Week

The United States has the highest maternal mortality in the developed world with cardiovascular disease as the leading cause of pregnancy-related deaths. In response to this, the emerging subspecialty of cardio-obstetrics has been growing over the past decade. Cardiologists with training and expertise in caring for patients with cardiovascular disease in pregnancy are essential to provide effective, comprehensive, multidisciplinary, and high-quality care for this vulnerable population. This document provides a blueprint on incorporation of cardio-obstetrics training into cardiovascular disease fellowship programs to improve knowledge, skill, and expertise among cardiologists caring for these patients, with the goal of improving maternal and fetal outcomes.

We Have to Really Decide: The Childbearing Decisions of Women With Congenital Heart Disease

BACKGROUND

Medical management and surgical improvement techniques permit persons with congenital heart conditions to live longer. Adults with congenital heart disease (CHD) have more childbearing options than previously available to them. However, there is an increased childbearing risk associated with certain types of CHD. Minimal investigation has been given to the childbearing decision-making experiences and adaptation of women with CHD.

OBJECTIVE

The aim of this study was to gain insight into the childbearing decision-making and adaptation experiences of women with CHD.

METHODS

Using a narrative inquiry approach, 17 adult women with CHD of any severity, of childbearing age, who had, within the last 5 years, made a decision regarding childbearing, were interviewed. In this study, we applied the key components of the Roy Adaptation Model to understand childbearing decision-making experiences and their adaptation. Data were analyzed using thematic analysis.

RESULTS

Data analysis revealed 5 stages of childbearing decision making: (1) prologue: stimulus to consider childbearing; (2) exploring childbearing options; (3) considering childbearing options; (4) choosing to bear or not to bear a child; and (5) epilogue: adapting to the childbearing decision. Adaptation occurred in the areas of self-concept (ie, emotional adaptation), role function (ie, relational adaptation), and interdependence (ie, interactional adaptation).

CONCLUSION

Childbearing decision making is a complex personal decision that is carefully and deliberately made. Women with CHD long for children and seek childbearing information from various resources and may experience grief regarding the inability to bear children. A greater understanding of childbearing decision making can be useful in addressing women's childbearing emotions and assist with adaptation to childbearing needs.

Pregnancy risk and contraception among reproductive-age women with rheumatic heart disease attending care at a tertiary cardiac center in Tanzania: a hospital-based cross-sectional study

BACKGROUND

Rheumatic heart disease (RHD) remains prevalent in the developing world and reproductive-age women are disproportionately affected. It is among the common est cardiac diseases during pregnancy and is associated with poor pregnancy outcomes. Despite its importance among reproductive-age women, there are no local studies that characterize the clinical characteristics, risk of poor pregnancy outcomes and contraception which represents one effective way to prevent unplanned pregnancies in this population.

METHODS

This was a hospital-based descriptive cross-sectional study. Non-pregnant reproductive-age women with echocardiographically diagnosed RHD were consecutively recruited from in- and out-patients units of the Jakaya Kikwete Cardiac Institute (JKCI). A clinical research form was used to gather socio-demographic, clinical characteristics, contraception status and echocardiographic information. The maternal/pregnancy risk class was determined using the modified World Health Organization (WHO) classification of maternal risk.

RESULTS

Two hundred thirty-eight women of reproductive age with RHD were recruited. The median age (range) was 36 years (15-49). Two-thirds were dyspneic on moderate exertion and 17.2% had New York Heart Association class IV heart failure. A quarter had atrial fibrillation/flutter. On echocardiography, mitral regurgitation was the most common valvular lesion (68.1%), followed by mitral stenosis (66.8%), and 12.2% of participants had reduced left ventricular ejection fraction. Two-thirds (66%) had a high pregnancy risk (class IV) based on the modified WHO classification system. The proportion of participants using contraception was 7.1% and common methods were: bilateral tubal ligation 5 of 17 (29.4%) and hormonal implant (4 of 17). The most common reason for the choice of a method was safety, 10 out of 17 (58.8%).

CONCLUSION

The majority of women of reproductive age with RHD in our hospital cohort are at the highest pregnancy risk based on the modified WHO classification and a very small proportion of them are on contraception. These results call for action among clinicians to offer counselling to these patients, educating them on their risk and offering appropriate contraception advice while waiting for definitive interventions.

Cardiovascular diseases in women: a differentiated view and risk stratification

Cardiovascular diseases are the main cause of mortality in men and women worldwide, surpassing mortality from all associated neoplasms. In women, its prevalence and mortality increase at menopause, but complications of reproductive age, such as preeclampsia and eclampsia, lead to increased cardiovascular risk throughout their lives. Coronary ischemic disease is is the leading cause of death in Brazil and worldwide, with atherosclerotic disease being the principal pathophysiological mechanism. However, in women, other mechanisms are associated with myocardial ischemia, such as microcirculation disease and/or vasospasm, due to the anatomical and hormonal characteristics of women in different stages of their lives. Knowledge of the most prevalent cardiovascular diseases in women, as well as the specific risk factors, the traditional ones with the greatest impact, and the under-recognized ones, is of fundamental importance in their risk stratification, diagnosis, and management, fundamentally aiming at reducing mortality.

Decision and economic analysis of hostile abortion laws compared with supportive abortion laws

BACKGROUND

On June 24, 2022, the US Supreme Court overturned Roe v Wade in Dobbs v Jackson Women's Health Organization. Therefore, several states banned abortion, and other states are considering more hostile abortion laws.

OBJECTIVE

This study aimed to assess the incidence of adverse maternal and neonatal outcomes in the hypothetical cohort where all states have hostile abortion laws compared with the pre-Dobbs v Jackson cohort (supportive abortion laws cohort) and examine the cost-effectiveness of these policies.

STUDY DESIGN

This study developed a decision and economic analysis model comparing the hostile abortion laws cohort with the supportive abortion laws cohort in a sample of 5.3 million pregnancies. Cost (inflated to 2022 US dollars) estimates were from a healthcare provider's perspective, including immediate and long-term costs. The time horizon was set to a lifetime. Probabilities, costs, and utilities were derived from the literature. The cost-effectiveness threshold was set to be at $100,000 per quality-adjusted life year. Probabilistic sensitivity analyses using the Monte Carlo simulation with 10,000 simulations were performed to assess the robustness of our results. The primary outcomes included maternal mortality and an incremental cost-effectiveness ratio. The secondary outcomes included hysterectomy, cesarean delivery, hospital readmission, neonatal intensive care unit admission, neonatal mortality, profound neurodevelopmental disability, and incremental cost and effectiveness.

RESULTS

In the base case analysis, the hostile abortion laws cohort had 12,911 more maternal mortalities, 7518 more hysterectomies, 234,376 more cesarean deliveries, 102,712 more hospital readmissions, 83,911 more neonatal intensive care unit admissions, 3311 more neonatal mortalities, and 904 more cases of profound neurodevelopmental disability than the supportive abortion laws cohort. The hostile abortion laws cohort was associated with more cost ($109.8 billion [hostile abortion laws cohort] vs $75.6 billion [supportive abortion laws cohort]) and 120,749,900 fewer quality-adjusted life years with an incremental cost-effectiveness ratio of negative $140,687.60 than the supportive abortion laws cohort. Probabilistic sensitivity analyses suggested that the chance of the supportive abortion laws cohort being the preferred strategy was more than 95%.

CONCLUSION

When states consider enacting hostile abortion laws, legislators should consider an increase in the incidence of adverse maternal and neonatal outcomes.

Key outcomes for reporting in studies of pregnant women with multiple long-term conditions: a qualitative study

BACKGROUND

Maternal multiple long-term conditions are associated with adverse outcomes for mother and child. We conducted a qualitative study to inform a core outcome set for studies of pregnant women with multiple long-term conditions.

METHODS

Women with two or more pre-existing long-term physical or mental health conditions, who had been pregnant in the last five years or planning a pregnancy, their partners and health care professionals were eligible. Recruitment was through social media, patients and health care professionals' organisations and personal contacts. Participants who contacted the study team were purposively sampled for maximum variation. Three virtual focus groups were conducted from December 2021 to March 2022 in the United Kingdom: (i) health care professionals (n = 8), (ii) women with multiple long-term conditions (n = 6), and (iii) women with multiple long-term conditions (n = 6) and partners (n = 2). There was representation from women with 20 different physical health conditions and four mental health conditions; health care professionals from obstetrics, obstetric/maternal medicine, midwifery, neonatology, perinatal psychiatry, and general practice. Participants were asked what outcomes should be reported in all studies of pregnant women with multiple long-term conditions. Inductive thematic analysis was conducted. Outcomes identified in the focus groups were mapped to those identified in a systematic literature search in the core outcome set development.

RESULTS

The focus groups identified 63 outcomes, including maternal (n = 43), children's (n = 16) and health care utilisation (n = 4) outcomes. Twenty-eight outcomes were new when mapped to the systematic literature search. Outcomes considered important were generally similar across stakeholder groups. Women emphasised outcomes related to care processes, such as information sharing when transitioning between health care teams and stages of pregnancy (continuity of care). Both women and partners wanted to be involved in care decisions and to feel informed of the risks to the pregnancy and baby. Health care professionals additionally prioritised non-clinical outcomes, including quality of life and financial implications for the women; and longer-term outcomes, such as children's developmental outcomes.

CONCLUSIONS

The findings will inform the design of a core outcome set. Participants' experiences provided useful insights of how maternity care for pregnant women with multiple long-term conditions can be improved.

Improving long-term care and outcomes of congenital heart disease: fulfilling the promise of a healthy life

Advances in the prevention, diagnosis, and treatment for congenital heart disease (CHD), the most common birth defect in China, have drastically improved survival for individuals with the disease. However, China's current health system is not well prepared to manage the growing population of people with CHD and their complex medical needs, which range from early detection of the condition and intervention for physical, neurodevelopmental, and psychosocial impairment, to long-term management of major complications and chronic health problems. Health disparities caused by long-standing regional differences in access to care pose challenges when major complications such as pulmonary hypertension arise, and when individuals with complex CHD become pregnant and give birth. Currently, no data sources track neonates, children, adolescents, and adults with CHD in China and delineate their clinical characteristics and use of health resources. This scarcity of data should warrant attention from the Chinese Government and relevant specialists in the field. In the third paper of the Series on CHD in China, we summarise key literature and current data to identify knowledge gaps and call for concerted efforts by the government, hospitals, clinicians, industries, and charitable organisations to develop an actionable, lifelong framework of congenital cardiac care that is accessible and affordable for all individuals with CHD.

Pregnancy in women with congenital heart disease: a focus on management and preventing the risk of complications

INTRODUCTION

Congenital heart disease (CHD) is the most common cardiac disorder in pregnancy in the western world (around 80%). Due to improvements in surgical interventions more women with CHD are surviving to adulthood and choosing to become pregnant.

AREAS COVERED

Preconception counseling, antenatal management of CHDs and strategies to prevent maternal and fetal complications.Preconception counseling should start early, before the transition to adult care and be offered to both men and women. It should include the choice of contraception, lifestyle modifications, pre-pregnancy optimization of cardiac state, the chance of the child inheriting a similar cardiac lesion, the risks to the mother, and long-term prognosis. Pregnancy induces marked physiological changes in the cardiovascular system that may precipitate cardiac complications. Risk stratification is based on the underlying cardiac disease and data from studies including CARPREG, ZAHARA, and ROPAC.

EXPERT OPINION

Women with left to right shunts, regurgitant lesions, and most corrected CHDs are at lower risk and can be managed in secondary care. Complex CHD, including systemic right ventricle need expert counseling in a tertiary center. Those with severe stenotic lesions, pulmonary artery hypertension, and Eisenmenger's syndrome should avoid pregnancy, be given effective contraception and managed in a tertiary center if pregnancy does happen.

Contemporary management of infective endocarditis in pregnancy

INTRODUCTION

Infective endocarditis (IE) during pregnancy is a rare condition that is associated with a high level of morbidity and mortality. The epidemiology, diagnosis, treatment, and prognosis have changed significantly in the last two decades. The declining incidence of rheumatic heart disease, improved life expectancy with congenital heart disease, advances in cardiac surgery and cardiac devices, rise in resistant microorganisms, complications of the opioid epidemic, and increasing maternal age are some of the many factors contributing to these changes.

AREAS COVERED

This article explores existing literature on the topic including case reports, case series, registry data, and clinical guidelines. The focus of this article is the evolving epidemiology, predisposing factors and preventative measures, clinical presentation, investigation, management, and potential complications of IE in pregnancy.

EXPERT OPINION

Robust prospective data on the management of IE in pregnancy is lacking, and obtaining these data will be very challenging. It is imperative that international registries are used to provide data on best clinical practices and inform future clinical guidelines. Multimodal imaging should be incorporated in the investigation of complicated cases. A multidisciplinary approach to the management of this rare and life-threatening condition is essential to ensure the best outcomes for both the mother and the fetus.

Introducing and Implementing Genetic Assessment in Cardio-Obstetrics Clinical Practice: Clinical and Genetic Workup of Patients with Cardiomyopathy

Cardiovascular disease (CVD) during pregnancy varies significantly worldwide, influenced by factors such as access to healthcare, delayed diagnosis, causes, and risk factors. Our study sought to explore the spectrum of CVD present in pregnant women in the United Arab Emirates to better understand this population's unique needs and challenges. Central to our study is an emphasis on the importance of implementing a multidisciplinary approach that involves the collaboration of obstetricians, cardiologists, geneticists, and other healthcare professionals to ensure that patients receive comprehensive and coordinated care. This approach can also help identify high-risk patients and implement preventive measures to reduce the occurrence of adverse maternal outcomes. Furthermore, increasing awareness among women about the risk of CVD during pregnancy and obtaining detailed family histories can help in the early identification and management of these conditions. Genetic testing and family screening can also aid in identifying inherited CVD that can be passed down through families. To illustrate the significance of such an approach, we provide a comprehensive analysis of five women's cases from our retrospective study of 800 women. The findings from our study emphasize the importance of addressing maternal cardiac health in pregnancy and the need for targeted interventions and improvements in the existing healthcare system to reduce adverse maternal outcomes.

Maternal and fetal/neonatal outcomes of pregnancies complicated by pulmonary hypertension: a retrospective study of 154 patients

OBJECTIVES

To determine the main clinical and demographic outcomes related to Pulmonary Hypertension (PH) and adverse obstetric and fetal/neonatal outcomes.

METHODS

This study retrospectively analyzed the medical record data of 154 patients with PH who were admitted to the Third Affiliated Hospital of Guangzhou Medical University between January 2011 and December 2020.

RESULTS

According to the severity of elevated Pulmonary Artery Systolic Pressure (PASP), 82 women (53.2%) were included in the mild PH group, 34 (22.1%) were included in the moderate PH group, and 38 (24.7%) were included in the severe PH group. There were significant differences in the incidence of heart failure, premature delivery, Very-Low-Birth-Weight (VLBW) infants, and Small-for-Gestational-Age (SGA) infants among the three PH groups (p < 0.05). Five (3.2%) women died within 7-days after delivery, 7 (4.5%) fetuses died in utero, and 3 (1.9%) neonates died. The authors found that PASP was an independent risk factor for maternal mortality. After adjustment for age, gestational weeks, systolic blood pressure, Body Mass Index (BMI), mode of delivery, and anesthesia, the risk of maternal mortality in the severe PH group was 20.21 times higher than that in the mild-moderate PH group (OR = 21.21 [95% CI 1.7∼264.17]), p < 0.05. All 131 (85.1%) patients were followed up for 12 months postpartum.

CONCLUSIONS

The authors found that the risk of maternal mortality in the severe PH group was significantly higher than that in the mild-moderate group, highlighting the importance of pulmonary artery pressure screening before pregnancy, early advice on contraception, and multidisciplinary care.

Anesthetic Care of the Pregnant Patient With Cardiovascular Disease: A Scientific Statement From the American Heart Association

The pregnancy-related mortality rate in the United States is excessively high. The American Heart Association is dedicated to fighting heart disease and recognizes that cardiovascular disease, preexisting or acquired during pregnancy, is the leading cause of maternal mortality in the United States. Comprehensive scientific statements from cardiology and obstetrics experts guide the treatment of cardio-obstetric patients before, during, and after pregnancy. This scientific statement aims to highlight the role of specialized cardio-obstetric anesthesiology care, presenting a systematic approach to the care of these patients from the anesthesiology perspective. The anesthesiologist is a critical part of the pregnancy heart team as the perioperative physician who is trained to prevent or promptly recognize and treat patients with peripartum cardiovascular decompensation. Maternal morbidity is attenuated with expert anesthesiology peripartum care, which includes the management of neuraxial anesthesia, inotrope and vasopressor support, transthoracic echocardiography, optimization of delivery location, and consideration of advanced critical care and mechanical support when needed. Standardizing the anesthesiology approach to patients with high peripartum cardiovascular risk and ensuring that cardio-obstetrics patients have access to the appropriate care team, facilities, and advanced cardiovascular therapies will contribute to improving peripartum morbidity and mortality.

Prevalence, trends, and outcomes of cardiovascular diseases in pregnant patients in the USA: 2010-19

AIMS

Contemporary data on the prevalence, trends, and outcomes of cardiovascular diseases (CVDs) in pregnant patients are limited. This study aimed to analyse the prevalence, trends, and outcomes of CVD and their subtypes in hospitalized pregnant patients in the USA.

METHODS AND RESULTS

This retrospective population-based cohort study used the Nationwide Readmission Database to identify all hospitalized pregnant patients from 1 January 2010, to 31 December 2019. Data analyses were conducted from January to February 2022. Pregnancy-associated hospitalizations were identified. The main outcomes were the prevalence and trend of CVD in pregnant patients. 39 212 104 hospitalized pregnant patients were identified: 4 409 924 with CVD (11.3%) and 34 802 180 without CVD (88.8%). The annual age-adjusted CVD prevalence increased from 9.2% in 2010 to 14.8% in 2019 (P < 0.001). Hypertensive disorder of pregnancy (1069/10 000) was the most common, and aortic dissection (0.1/10 000) was the least common CVD. The trends of all CVD subtypes increased; however, the trend of valvular heart disease decreased. Age-adjusted in-hospital all-cause mortality was 8.2/10 000 in CVD, but its trend decreased from 8.1/10 000 in 2010 to 6.5/10 000 in 2019 (P < 0.001). CVD was associated with 15.51 times higher odds of in-hospital all-cause mortality compared with non-CVD patients [odds ratio (OR): 15.51, 95% confidence interval (CI)13.22-18.20, P < 0.001]. CVD was associated with higher 6-week postpartum readmission (OR: 1.97, 95% CI: 1.95-1.99), myocardial infarction (OR: 3.04, 95% CI: 2.57-3.59), and stroke (OR: 2.66, 95% CI: 2.41-2.94)(P < 0.001 for all).

CONCLUSION

There is an increasing age-adjusted trend in overall CVD and its subtypes among pregnant patients in the USA from 2010 to 2019. Pregnant patients with CVD had higher odds of in-hospital mortality than those without CVD. However, in-hospital all-cause mortality among patients with and without CVD has decreased over the past 10 years. CVD was associated with higher 6-week postpartum all-cause readmission, myocardial infarction, and stroke rates.

Maternal and child outcomes for pregnant women with pre-existing multiple long-term conditions: protocol for an observational study in the UK

INTRODUCTION

One in five pregnant women has multiple pre-existing long-term conditions in the UK. Studies have shown that maternal multiple long-term conditions are associated with adverse outcomes. This observational study aims to compare maternal and child outcomes for pregnant women with multiple long-term conditions to those without multiple long-term conditions (0 or 1 long-term conditions).

METHODS AND ANALYSIS

Pregnant women aged 15-49 years old with a conception date between 2000 and 2019 in the UK will be included with follow-up till 2019. The data source will be routine health records from all four UK nations (Clinical Practice Research Datalink (England), Secure Anonymised Information Linkage (Wales), Scotland routine health records and Northern Ireland Maternity System) and the Born in Bradford birth cohort. The exposure of two or more pre-existing, long-term physical or mental health conditions will be defined from a list of health conditions predetermined by women and clinicians. The association of maternal multiple long-term conditions with (a) antenatal, (b) peripartum, (c) postnatal and long-term and (d) mental health outcomes, for both women and their children will be examined. Outcomes of interest will be guided by a core outcome set. Comparisons will be made between pregnant women with and without multiple long-term conditions using modified Poisson and Cox regression. Generalised estimating equation will account for the clustering effect of women who had more than one pregnancy episode. Where appropriate, multiple imputation with chained equation will be used for missing data. Federated analysis will be conducted for each dataset and results will be pooled using random-effects meta-analyses.

ETHICS AND DISSEMINATION

Approval has been obtained from the respective data sources in each UK nation. Study findings will be submitted for publications in peer-reviewed journals and presented at key conferences.

Outcomes of pregnant women hospitalized with unrepaired congenital heart disease: Insights from a multidisciplinary center in Vietnam

Background

In developing countries, fewer women have access to multidisciplinary congenital heart disease and reproductive programs staffed by experts. We report pregnancy outcomes of a multidisciplinary healthcare strategy utilizing an in-hospital teamwork approach in Vietnam.

Methods

This retrospective cohort study included pregnant women with unrepaired congenital heart disease managed at a referral cardiovascular center.

Results

Undiagnosed congenital heart disease before pregnancy, a lack of pre-pregnancy cardiology counseling, and modified World Health Organization class III/IV were common. Under the multispecialty healthcare strategy, although the rate of maternal death was 8.2% in the modified World Health Organization class IV group, no deaths occurred in any other group. Fetal/neonatal complications occurred in 54% of pregnancies, and 49.4% of neonates survived. Poor pregnancy outcomes were associated with admission during the first/seconde trimester for fetus/neonates, third trimester for mother, modified World Health Organization class III/IV, cyanosis, and heart failure.

Conclusion

The outcomes of pregnant women with unrepaired congenital heart disease were poor but seemed to improve with a multidisciplinary in-hospital healthcare teamwork strategy.
