RESUMO
BACKGROUND: Missouri has one of the highest rates of maternal mortality in the United States. To date, there are currently no studies describing birthing peoples' knowledge or perceptions of contributing causes of maternal mortality. An improved understanding of population-specific knowledge can help to define how best to design targeted interventions to reduce disease-specific causes of maternal mortality. OBJECTIVE: This study aimed to examine the knowledge and understanding of maternal mortality in a Missouri birthing population. STUDY DESIGN: A 46-question, cross-sectional survey to assess the familiarity with local maternal mortality rates, groups affected, and causality was developed by the Missouri Perinatal Quality Collaborative and the Maternal-Child Learning and Action Network and emailed to a random sample of birthing people across Missouri. Those who identified as someone with birthing potential with a Missouri zip code and who were ≥18 years of age were eligible for inclusion. Unadjusted descriptive statistics were generated and stratified by age, race, and region. RESULTS: Among 2196 surveys sent, 1738 people completed the survey. Of those who responded, 78.2% were aware of the risk of pregnancy-related death with 14.7% reporting that they intimately knew someone who died. When asked if a certain group is affected disproportionately more, 66.4% responded affirmatively. Black (58.7%), uninsured (61.8%), poor (71.0%), those with substance abuse disorders (57.4%), and Native American (28.8%) birthing people were identified as groups that were perceived as suffering higher rates of maternal death. When polled on etiology, severe bleeding (56.9%) was believed to be the leading cause of death, and the second stage of labor was thought to be the period of highest risk (42.3%). Beliefs about the timing of death differed by age (P=.042) but not race (P=.81) or region (P=.191). CONCLUSION: Missouri birthing people are cognizant of the social factors associated with increased maternal mortality but are unaware of the leading causes of death, namely cardiovascular disease and mental health conditions. Future Perinatal Quality Collaborative work should focus on campaigns that raise public awareness about cardiovascular disease and mental health-related birthing risks and the importance of monitoring early warning signs after delivery.

BACKGROUND: The physiological changes to the cardiovascular system during pregnancy are considerable and are more pronounced in those with cardiac disease. In the general population, noninvasive hemodynamic monitoring is a valid alternative to pulmonary artery catheterization, which poses risk in the pregnant population. There is limited data on noninvasive cardiac output monitoring in pregnancy as an alternative to pulmonary artery catheterization. OBJECTIVE: We sought to compare transthoracic echocardiography with a noninvasive cardiac output monitor (NICOM, Cheetah Medical) in pregnant patients with and without cardiac disease. STUDY DESIGN: This was a prospective, open-label validation study that compared 2-dimensional transthoracic echocardiography with NICOM estimations of cardiac output in each trimester of pregnancy and the postpartum period. Participants with and without cardiac disease with a singleton gestation were included. NICOM estimations of cardiac output were derived from thoracic bioreactance and compared with 2-dimensional transthoracic echocardiography for both precision and accuracy. A mean percentage difference of ±30% between the 2 devices was considered acceptable agreement between the 2 measurement techniques. RESULTS: A total of 58 subjects were enrolled; 36 did not have cardiac disease and 22 had cardiac disease. Heart rate measurements between the 2 devices were strongly correlated in both groups, whereas stroke volume and cardiac output measurements showed weak correlation. When comparing the techniques, the NICOM device overestimated cardiac output in the control group in all trimesters and the postpartum period (mean percentage differences were 50.3%, 52.7%, 48.1%, and 51.0% in the first, second, and third trimesters and the postpartum period, respectively). In the group with cardiac disease, the mean percentage differences were 31.9%, 29.7%, 19.6%, and 35.2% for the respective timepoints. CONCLUSION: The NICOM device consistently overestimated cardiac output when compared with 2-dimensional transthoracic echocardiography at all timepoints in the control group and in the first trimester and postpartum period for the cardiovascular disease group. The physiological changes of pregnancy, specifically the mean chest circumference and total body water, may alter the accuracy of the cardiac output measurement by the NICOM device as they are currently estimated. Although NICOM has been validated for use in the critical care setting, there is insufficient data to support its use in pregnancy.

BACKGROUND: Treatment with antibiotics at the time of preterm prelabor rupture of membranes (PPROM) has been shown to prolong pregnancy. Due to the recurrent shortage of erythromycin, azithromycin has been substituted in the traditional regimen; however, there are little data on optimal dosing. OBJECTIVE: The objective of this study was to determine whether there is a difference in latency from onset of PPROM to delivery in patients who received a single dose of azithromycin compared with a 5-day course. METHODS: This was a single-center, multisite, retrospective, IRB approved analysis of patients admitted with a diagnosis of PPROM. Patients were included if rupture occurred between 22 0/7 and 33 6/7 weeks of gestation and received either a single dose or a 5-day course of azithromycin along with a beta lactam. RESULTS: A total of 376 patients were reviewed with 296 patients included in the final analysis. There was no statistical difference in the primary outcome of latency days in patients who received the 5-day versus the single-dose course (4 vs 5 days, P = 0.641). There was a significantly higher rate of histologic chorioamnionitis in the single-dose course of azithromycin (46.4% vs 62.6%, P = 0.006). CONCLUSIONS AND RELEVANCE: There was no difference in latency for patients who received a 5-day course of azithromycin versus a single dose for the treatment of PPROM. A higher rate of histologic chorioamnionitis was observed in those who received the single-day course. Prospective follow-up studies are needed to confirm these findings.

Cardiac conditions are the leading cause of pregnancy-related deaths and disproportionately affect non-Hispanic Black people. Multidisciplinary maternal mortality review committees have found that most people who died from cardiac conditions during pregnancy or postpartum were not diagnosed with a cardiovascular disease before death and that more than 80% of all pregnancy-related deaths, regardless of cause, were preventable. In addition, other obstetric complications, such as preeclampsia and gestational diabetes, are associated with future cardiovascular disease risk. Those with cardiac risk factors and those with congenital and acquired heart disease require specialized care during pregnancy and postpartum to minimize risk of preventable morbidity and mortality. This bundle provides guidance for health care teams to develop coordinated, multidisciplinary care for pregnant and postpartum people with cardiac conditions and to respond to cardio-obstetric emergencies. This bundle is one of several core patient safety bundles developed by the Alliance for Innovation on Maternal Health that provide condition- or event-specific clinical practices for implementation in appropriate care settings. The Cardiac Conditions in Obstetric Care bundle is organized into five domains: 1) Readiness , 2) Recognition and Prevention , 3) Response , 4) Reporting and Systems Learning , and 5) Respectful Care . This bundle is the first by the Alliance to be developed with the fifth domain of Respectful Care . The Respectful Care domain provides essential best practices to support respectful, equitable, and supportive care to all patients. Further health equity considerations are integrated into elements in each domain.

May Thurner Syndrome contributes to thromboembolic disease and can cause significant morbidity in pregnant patients secondary to exaggerated anatomic relationships and physiologic changes in the hematologic system favoring thrombogenesis. Because this condition is both underrecognized and underreported, management in pregnant and postpartum patients is based on expert opinion without any formal evidence-based guidance. Herein, we review five pregnancies in four patients with May Thurner Syndrome and general management strategies. Through collaborative and multidisciplinary care, patients with May Thurner Syndrome can be safely and successfully managed during pregnancy and the postpartum period with appropriate anticoagulation.
RESUMO
Heart disease is the leading cause of pregnancy-related mortality in the United States and has led to the development of combined cardio-obstetrics (COB) clinics as a model for prenatal care. In other areas of medicine, these types of collaborative care models have shown improvement in morbidity, mortality, and patient satisfaction. There is some data to suggest that a combined COB clinic improves maternal outcomes but there is no data to suggest patients prefer this type of care model. This study aims to evaluate patient satisfaction in a combined COB clinic and whether this type of model enhances perceived communication and knowledge uptake. A quality questionnaire was developed to assess patient perceptions regarding communication, satisfaction, and perceived knowledge. Patients who attended the clinic (n = 960) from 2014-2020 were contacted by email, with a response received from 119 (12.5%). Participants completed a questionnaire assessing satisfaction and perceived knowledge uptake with answers based on a Likert scale (7 representing very satisfied and 1 representing very unsatisfied). Safe and effective contraceptive use was evaluated by multiple choice options. Knowledge was also assessed by comparing contraceptive use before and after the clinic. Participants reported high levels of satisfaction with the clinic (6.2 ± 1.5), provider-to-patient communication (6.1 ± 1.6), and with the multidisciplinary appointment approach (6.3 ± 1.5). As well, participants reported an increase in knowledge about heart disease a result of collaborative counseling. In summary, a multidisciplinary approach to cardio-obstetrics not only improves outcomes but is a patient satisfier.
RESUMO
In contrast to most industrialized countries, maternal mortality in the USA is rising. Cardiovascular disease, both acquired heart disease (e.g. coronary disease, arrhythmias, and heart failure), as well as congenital heart disease survivors, are all potentially important factors in explaining this worrisome trend. Increase in acquired cardiac disease is likely attributable to greater rates of obesity, diabetes, hypertension, and an increase in the incidence of advanced maternal age, while congenital heart disease in pregnancy is increasing due to advances in pediatric cardiovascular surgery. Despite the growing cardiovascular risk of pregnant women, most obstetricians and cardiologists have limited experience in caring for women with heart disease. Accordingly, management is largely guided by expert opinion likely to vary greatly across centers. To address these challenges, a multidisciplinary approach to care that includes both cardiologists and obstetricians could leverage the knowledge of both specialties and support streamlined communication between the patient and her providers. Our experience highlights the necessary components and essential infrastructure for building a center of excellence in treating pregnant women with heart disease.Condensation: A guide for creating a center of excellence for prenatal care for women with cardiovascular disease.The problem: Cardiac disease is the leading cause of maternal mortality, and pregnancies affected by cardiac disease continue to rise, both congenital and acquired.The solution: Maternal fetal medicine, obstetricians, and cardiologists can join together in tertiary facilities to create Maternal Cardiac Centers of Excellence to provide multidisciplinary, structured care for these high-risk patients.

Cardiovascular disease and cardiovascular disease-related disorders remain among the most common causes of maternal morbidity and mortality in the United States. Due to increased rates of obesity, delayed childbearing, and improvements in medical technology, greater numbers of women are entering pregnancy with preexisting medical comorbidities. Use of cardiovascular medications in pregnancy continues to increase, and medical management of cardiovascular conditions in pregnancy will become increasingly common. Obstetricians and cardiologists must familiarize themselves with the pharmacokinetics of the most commonly used cardiovascular medications in pregnancy and how these medications respond to the physiologic changes related to pregnancy, embryogenesis, and lactation.

Maternal mortality in the United States is the highest among all developed nations, partly because of the increased prevalence of cardiovascular disease in pregnancy and beyond. There is growing recognition that specialists involved in caring for obstetric patients with cardiovascular disease need training in the new discipline of cardio-obstetrics. Training can include integrated formal cardio-obstetrics curricula in general cardiovascular disease training programs, and developing and disseminating joint cardiac and obstetric societal guidelines. Other efforts to help strengthen the cardio-obstetric field include increased collaborations and advocacy efforts between stakeholder organizations, development of US-based registries, and widespread establishment of multidisciplinary pregnancy heart teams. In this review, we present the current challenges in creating a cardio-obstetrics community, present the growing need for education and training of cardiovascular disease practitioners skilled in the care of obstetric patients, and identify potential solutions and future efforts to improve cardiovascular care of this high-risk patient population.

PURPOSE: In the USA, maternal mortality has been rising since the 1980s. Cardiovascular disease is recognized as the leading cause of this worrisome trend, and a multidisciplinary approach to the care of patients with cardiovascular conditions during pregnancy is becoming increasingly important. We outline the literature supporting this multidisciplinary approach, highlight our center's experience in building and expanding an integrated cardio-obstetrics practice, and provide guidance regarding patient selection and management within a combined practice. Antenatal management patterns and delivery planning for patients with cardiovascular disease during pregnancy vary substantially among cardiovascular and obstetric and maternal fetal medicine practices in the USA. The need for multidisciplinary care between cardiologists and obstetricians is evident and has been supported by best practice statements from the American Heart Association, the American College of Obstetrics and Gynecology, and the Cardiac Disease in Pregnancy Study (CARPREG) investigators, whose CARPREG II risk score included "late first antenatal visit" as a predictor of adverse outcomes of pregnancy. CONCLUSIONS: We have solid evidence supporting a multidisciplinary approach to the care of patients with cardiac conditions in pregnancy. This approach is optimal because it facilitates a consistent and clear message to the patient (and those caring for each patient) regarding management and risks associated with pregnancy, as well as subsequent risk and postpartum follow-up. We support the extension of clinical collaboration between obstetricians and cardiologists to the research realm and know that working together to investigate the outcomes of moms with heart conditions and their babies will provide clinically meaningful information to support the care of these unique patients.
RESUMO
PURPOSE OF REVIEW: Maternal mortality in the United States is highest among all developed nations and continues to rise. The leading cause of morbidity and mortality during pregnancy and the postpartum period is cardiovascular disease. While there are large European and Canadian studies exploring the care and outcomes of moms with heart disease in pregnancy, there are no large prospective studies to guide the care of this growing group of patients in the US. We review the current approach to the management of patients with heart disease in pregnancy and the gaps in knowledge thereof. RECENT FINDINGS: Currently, antenatal management and delivery planning are highly variable for patients with heart disease in pregnancy and maternal risk models' application to the US patient population is limited by their derivation from an international cohort of patients and their focus on patients with congenital heart disease. As the need for interdisciplinary care between cardiologists and obstetricians becomes evident, and as broad research efforts within this space are very much needed, we propose a research collaborative called the Heart Outcomes in Pregnancy: Expectations (HOPE) for Mom and Baby Registry. The HOPE Registry aims to address key clinical questions surrounding the preconception period, antenatal care, delivery planning and outcomes, and long-term postpartum care and outcomes of these unique patients. We have made progress in recent years by recognizing the clinical need to address and standardize the management of patients with heart disease in pregnancy. We now must initiate and propel US-based cardio-obstetrics research to address key gaps in knowledge and variability in the care of patients with heart disease in pregnancy.

BACKGROUND: Controversy exists regarding the optimal route of delivery for fetuses who are diagnosed prenatally with myelomeningocele. Current recommendations are based partly on antiquated studies with questionable methods. All studies that have been published to date suffer from nonstandardized outcome measures, selection bias, and small sample size. The larger studies are >15 years old. OBJECTIVE: The purpose of this study was to provide information for evidence-based decision-making regarding the impact of route of delivery on motor outcomes for pediatric patients with prenatally were diagnosed myelomeningocele in a well-defined retrospective cohort. STUDY DESIGN: Medical records were reviewed retrospectively for all neonates who had been diagnosed with a myelomeningocele at birth from 1995-2015 within the University of Pittsburgh Medical Center system, as identified through the Children's Hospital of Pittsburgh Neurosurgery Department operative database. Records were matched with maternal records with the use of the Center for Assistance in Research that used eRecord. Data from 72 maternal-neonatal pairs were analyzed for multiple variables. The primary outcome measure was the difference between the functional and anatomic motor levels in the child at the age of 2 years, stratified by mode of delivery and presence or absence of labor. The sample size necessary to detect a difference between the groups with power of 0.8 and significance of .05 was calculated to be 52 subjects total (26 per group). RESULTS: Functional levels were slightly better than predicted by anatomic levels for all pediatric patient groups, regardless of mode of delivery or presence of labor. Anatomic levels were slightly lower (better), and defects were smaller for those infants who underwent vaginal delivery or a trial of labor, likely attributable to selection bias. Attempts to correct for this selection bias did not change the results. No other outcomes that were analyzed were associated significantly with mode of delivery or presence of labor. CONCLUSION: No benefit to motor function from delivery by cesarean section or avoidance of labor was demonstrated statistically in this mother-infant cohort.

BACKGROUND: In high-income countries, maternal obesity is one of the most important modifiable causes of stillbirth, yet the pathways underpinning this association remain unclear. OBJECTIVE: We estimated the association between maternal prepregnancy body mass index (BMI) and the risk of stillbirth defined by pathophysiologic contributors or causes. DESIGN: Using a case-cohort design, we randomly sampled 1829 singleton deliveries from a cohort of 68,437 eligible deliveries at Magee-Womens Hospital in Pittsburgh, Pennsylvania (2003-2010), and augmented it with all remaining cases of stillbirth for a total of 658 cases. Stillbirths were classified based on probable cause(s) of death (maternal medical conditions, obstetric complications, fetal abnormalities, placental diseases, and infection). A panel of clinical experts reviewed medical records, placental tissue slides and pathology reports, and fetal postmortem reports of all stillbirths. Causes of fetal death were assigned by using the Stillbirth Collaborative Research Network Initial Causes of Fetal Death protocol from the Eunice Kennedy Shriver National Institute of Child Health and Human Development. Proportional hazards models were used to estimate the BMI-stillbirth association after adjustment for confounders. RESULTS: The rate of stillbirth among lean, overweight, obese, and severely obese women was 7.7, 10.6, 13.9, and 17.3 per 1000 live-born and stillborn infants, respectively. Adjusted stillbirth HRs (95% CIs) were 1.4 (1.1, 1.8) for overweight, 1.8 (1.3, 2.4) for obese, and 2.0 (1.5, 2.8) for severely obese women, respectively, compared with lean women; associations strengthened when limited to antepartum stillbirths. Obesity and severe obesity were associated with stillbirth resulting from placental diseases, hypertension, fetal anomalies, and umbilical cord abnormalities. BMI was not related to stillbirth caused by placental abruption, obstetric conditions, or infection. CONCLUSIONS: Multiple mechanisms appear to link obesity to stillbirth. Interventions to reduce stillbirth among obese mothers should consider targeting stillbirth due to hypertension and placental diseases-the most common causes of fetal death in this at-risk group.
