Abstract
Cardiovascular disease is the primary cause of pregnancy-related mortality and morbidity in the United States, and maternal mortality has increased over the last decade. Pregnancy and the postpartum period are associated with significant vascular, metabolic, and physiologic adaptations that can unmask new heart failure or exacerbate heart failure symptoms in women with known underlying cardiomyopathy. There are unique management considerations for heart failure in women throughout pregnancy, and it is imperative that clinicians caring for pregnant women understand these important principles. Early involvement of multidisciplinary cardio-obstetrics teams is key to optimizing maternal and fetal outcomes. In this review, we discuss the unique challenges and opportunities in the diagnosis of heart failure in pregnancy, management principles along the continuum of pregnancy, and the safety of heart failure therapies during and after pregnancy.

Abstract
BACKGROUND The management of symptomatic gestational supraventricular tachycardia (SVT) is challenging and requires a multidisciplinary approach for optimal management. Catheter ablation during pregnancy has traditionally been considered a last option due to procedural safety and ionizing radiation risks. Recent advances including intracardiac echocardiography and multi-electrode electroanatomic mapping have greatly enhanced the safety and efficacy profile to successfully perform ablations with minimal to no fluoroscopy even during pregnancy. This is the first review to compare the efficacy, safety, and aggregate outcomes of purely zero-fluoroscopic and minimal fluoroscopic approaches in gestational SVT. METHODS A literature search was performed for catheter ablations in the past 15 years for gestational arrhythmias that used minimal or no fluoroscopy. Sixteen cases describing catheter ablations with zero-fluoroscopy were compared to twenty-four cases using minimal fluoroscopy, defined as total documented exposure time of less than 10 min. RESULTS Analysis of both groups demonstrated that zero-fluoroscopic approaches have comparable efficacy and procedural safety outcomes with the utilization of earlier trimester ablations and in older maternal ages. The utilization of electroanatomic mapping with or without concomitant intracardiac echocardiography in the zero-fluoroscopy group further demonstrated equal efficacy rates of successful ablation when compared to the control group. Furthermore, there were no reported immediate or long-term periprocedural complications in either group, including delivery outcomes. CONCLUSION Our review demonstrates that zero-fluoroscopy catheter ablation for SVT in pregnancy is both effective and safe when compared to minimal fluoroscopy ablations while eliminating the theoretical risks of ionizing radiation.

Abstract
Periventricular hemorrhage is bleeding from the subependymal germinal matrix, which results in severe motor disorders, mental and speech developmental delay.Purpose. The study aims to evaluate risk factors, the trends of neurological disorders, and the outcomes of neonatal periventricular hemorrhage in children whose mothers were on gravidary anticoagulant and/or antiplatelet therapy.Material and methods. The study examined 160 newborns with PVH: Group I — 53 (37.9%) children born from pregnancy on the background of antiplatelet and/or anticoagulant therapy for hypercoagulation syndrome; Group II — 87 (62.1%) children born from pregnancy on the background of antiplatelet and/or anticoagulant therapy to treat degree 1A uteroplacental blood flow disorders; Group III — 20 children born from pregnancy without corticosteroids and antiplatelet and/or anticoagulant therapy. All newborns underwent clinical and neurological examination and neurosonography; data on somatic and obstetric anamnesis were obtained from accompanying medical records.Results. In children of Groups I and II a more severe condition of newborns with periventricular hemorrhage at birth was noted, a slower dynamics of restoration of muscle-postural tone and the pace of psychomotor development were observed compared to children in Group III. In Groups I and II a high incidence of epilepsy (5.7%) and cerebral palsy (6.4%) by 12 months of corrected age was revealed compared with the population.Conclusion. Gravidary anticoagulant and antiplatelet therapy might be considered as a risk factor for the development of intracranial hemorrhages and severe neurological disorders: epilepsy, cerebral palsy, mental and motor developmental delays.

Cardiovascular diseases in Africa in the twenty-first century: Gaps and priorities going forward. Front Cardiovasc Med 2022; 9:1008335.

Abstract
In 2015, the United Nations set important targets to reduce premature cardiovascular disease (CVD) deaths by 33% by 2030. Africa disproportionately bears the brunt of CVD burden and has one of the highest risks of dying from non-communicable diseases (NCDs) worldwide. There is currently an epidemiological transition on the continent, where NCDs is projected to outpace communicable diseases within the current decade. Unchecked increases in CVD risk factors have contributed to the growing burden of three major CVDs-hypertension, cardiomyopathies, and atherosclerotic diseases- leading to devastating rates of stroke and heart failure. The highest age standardized disability-adjusted life years (DALYs) due to hypertensive heart disease (HHD) were recorded in Africa. The contributory causes of heart failure are changing-whilst HHD and cardiomyopathies still dominate, ischemic heart disease is rapidly becoming a significant contributor, whilst rheumatic heart disease (RHD) has shown a gradual decline. In a continent where health systems are traditionally geared toward addressing communicable diseases, several gaps exist to adequately meet the growing demand imposed by CVDs. Among these, high-quality research to inform interventions, underfunded health systems with high out-of-pocket costs, limited accessibility and affordability of essential medicines, CVD preventive services, and skill shortages. Overall, the African continent progress toward a third reduction in premature mortality come 2030 is lagging behind. More can be done in the arena of effective policy implementation for risk factor reduction and CVD prevention, increasing health financing and focusing on strengthening primary health care services for prevention and treatment of CVDs, whilst ensuring availability and affordability of quality medicines. Further, investing in systematic country data collection and research outputs will improve the accuracy of the burden of disease data and inform policy adoption on interventions. This review summarizes the current CVD burden, important gaps in cardiovascular medicine in Africa, and further highlights priority areas where efforts could be intensified in the next decade with potential to improve the current rate of progress toward achieving a 33% reduction in CVD mortality.

Abstract
Low-molecular-weight heparin (LMWH) is suggested for thromboprophylaxis in
pregnant women with previous venous thromboembolism (VTE). Anyway,
there is only limited amount of studies evaluating the effect of LMWH on
hemostatic parameters during pregnancy of patients with previous VTE and the
need of secondary thromboprophylaxis. We therefore provide results of
prospective and longitudinal assessment of changes in hemostasis in high-risk
pregnant women at four times during pregnancy (T1–T4) and one time after the
postpartum period (T5) used for individualized modification of
thromboprophylaxis. In this study, the results of coagulation factor VIII
(FVIII) and protein S (PS) activity, ProC Global ratio and anti-Xa activity were
evaluated. Despite the thromboprophylaxis, an increased predisposition to
thromboembolic complications was detected (significant increase in FVIII
activity and decrease in PS function, ProC Global ratio not normalized even
after the postpartum period – p < .0001 between controls and
T5 for PS and ProC Global). These results indicate that hemostasis may not be
restored even 6 to 8 weeks after delivery and pose the question when is it safe
to withdraw the anticoagulant thromboprophylaxis in high-risk patients with
prior VTE.

Abstract
Extracorporeal membrane oxygenation (ECMO) has seen increasing use for critically ill pregnant and postpartum patients over the past decade. Growing experience continues to demonstrate the feasibility of ECMO in obstetric patients and attest to its favorable outcomes. However, the interaction of pregnancy physiology with ECMO life support requires careful planning and adaptation for success. Additionally, the maintenance of fetal oxygenation and perfusion is essential for safely continuing pregnancy during ECMO support. This review summarizes the considerations for use of ECMO in obstetric patients and how to address these concerns.

Abstract
OBJECTIVE The first aim of this study was to investigate the effect of apixaban on endometrial receptivity via immunohistochemical investigation of integrin β3 expression in pregnant rats. The second aim was to compare the endometrial effects of both subcutaneous and oral anticoagulant drugs in terms of integrin β3 expressions. METHODS A total of 24 rats were selected for this study and divided into three equal groups as control, enoxaparin and apixaban groups. Subcutaneous enoxaparin and oral apixaban were applied for 15 days starting on the first day of pregnancy. On the 15th day of pregnancy, all rats were killed by cervical dislocation, and uterine horns, including pregnancy materials, were investigated for pregnancy success and endometrial receptivity by using immunohistochemical integrin β3 staining. RESULTS Living, viable fetuses were higher in the apixaban group compared to the control group (p=0.037). Intensity and universality of immunohistochemical staining of integrin β3 for endometrial stroma were detected statistically higher in the apixaban group than the other groups. (p=0.009 for intensity, p=0.014 for universality). Endometrial epithelial and myometrial integrin β3 expression were detected to be identical between the groups (p=0.3). CONCLUSIONS Apixaban enhances endometrial receptivity via increasing integrin β3 expression in rats. This result can lead to further studies to be done in the future.

Abstract
The growing population of women with heart disease of reproductive age has been associated with an increasing number of high-risk pregnancies. Pregnant women with heart disease are a very heterogeneous population, with different risks for maternal cardiovascular, obstetric, and foetal complications. Adverse cardiovascular events during pregnancy pose significant clinical challenges, with uncertainties regarding diagnostic and therapeutic approaches potentially compromising maternal and foetal health. This review summarizes best practice for the treatment of common cardiovascular complications during pregnancy, based on expert opinion, current guidelines, and available evidence. Topics covered include heart failure (HF), arrhythmias, coronary artery disease, aortic and thromboembolic events, and the management of mechanical heart valves during pregnancy. Cardiovascular pathology is the leading cause of non-obstetric morbidity and mortality during pregnancy in developed countries. For women with pre-existing cardiac conditions, preconception counselling and structured follow-up during pregnancy are important measures for reducing the risk of acute cardiovascular complications during gestation and at the time of delivery. However, many women do not receive pre-pregnancy counselling often due to gaps in what should be lifelong care, and physicians are increasingly encountering pregnant women who present acutely with cardiac complications, including HF, arrhythmias, aortic events, coronary syndromes, and bleeding or thrombotic events. This review provides a summary of recommendations on the management of acute cardiovascular complication during pregnancy, based on available literature and expert opinion. This article covers the diagnosis, risk stratification, and therapy and is organized according to the clinical presentation and the type of complication, providing a reference for the practicing cardiologist, obstetrician, and acute medicine specialist, while highlighting areas of need and potential future research.

Abstract
Low-molecular-weight heparin (LMWH) is commonly used for preventing or treating venous thromboembolic disease (VTE) during pregnancy. The physiological changes in maternal metabolism have led to discussions on optimal LMWH dosing strategy and possible need for monitoring. The aim of this systematic review is to summarize and discuss whether LMWH dose adjustment according to anti-Xa provides superior effectiveness and safety compared with weight adjusted or fixed dosed LMWH in pregnant women. A systematic literature search was performed in PubMed, Embase, and Scopus on September 26, 2020. The study is reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Effectiveness was defined as episodes of thrombosis and safety as bleeding episodes. In total, 33 studies were included: 4 randomized controlled studies and 29 cohort studies. Prophylactic dosing strategies employing weight dosed, fixed dosed, or anti-Xa adjusted LMWH dosing performed equal in effectiveness and safety. In pregnant women with VTE or high thromboembolic risk, therapeutic weight-adjusted LMWH and weight plus anti-Xa-adjusted LMWH provided equal results in terms of effectiveness and safety. Pregnant women with mechanical heart valves (MHVs) received therapeutic anti-Xa-adjusted LMWH with four out of seven studies presenting mean peak anti-Xa within target ranges. Still, pregnant women with MHV experienced both thrombosis and bleeding with anti-Xa in target. Based on the results of this systematic review, current evidence does not support the need for anti-Xa monitoring when using LMWH as thromboprophylaxis or treatment during pregnancy. Nonetheless, the need for anti-Xa monitoring in pregnant women with MHV may need further scrutiny.

Abstract
INTRODUCTION Pregnancy in patients with mechanical heart valves (MHVs) is associated with high maternal complications and fetal complications.Anticoagulation treatments serve to decrease their venous clotting risk. Although some anticoagulation regimens have been used for patients during pregnancy with MHVs, no one is definitively superior among different regimens in recent studies. For a better understanding of the clinical treatment which anticoagulation regimen is more effective and safer during the pregnancy in patients with MHVs, a Bayesian network meta-analysis is necessary. METHODS AND ANALYSIS This protocol has been reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols. Related studies until April 2019 will be searched in the following databases: PubMed, Embase,SinoMed and the using the OVID interface to search for evidence-based medicine reviews. A clinical trial registry (www.ClinicalTrials.gov) was also searched for unpublished trials. Both experimental studies (randomised clinical trials) and observational studies (cohort studies, case-control studies and case series studies) will be included in this study. Quality assessment will be conducted using Cochrane Collaboration's tool or Newcastle-Ottawa Scale based on their study designs. The primary outcomes of interest will be the frequencies of serious maternal and fetal events. The additional outcomes of interest will be adverse maternal events, mode of delivery and adverse fetal events. Pairwise and network meta-analysis will be conducted using R (V.3.4.4, R Foundation for Statistical Computing, Vienna, Austria) and Stata (V.14, StataCorp). The ranking probabilities will be estimated at each possible rank for each anticoagulation regimen using the surface under the cumulative ranking curve. Statistical inconsistency assessment, subgroup analysis, sensitivity analysis and publication bias assessment will be performed. ETHICS AND DISSEMINATION Either ethics approval or patient consent is not necessary, because this study will be based on literature. The results of this study will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER CRD42019130659.

Abstract
PURPOSE OF REVIEW While the prognosis of peripartum cardiomyopathy (PPCM) is generally more favorable than other cardiomyopathies, PPCM can be associated with cardiogenic shock and significant maternal morbidity in young women. The management of a pregnant woman in cardiogenic shock necessitates consideration of harm to the fetus. This review focuses on the management of these women. RECENT FINDINGS A number of advances have increased the repertoire of therapies available to manage PPCM. Increased understanding of PPCM pathophysiology has led to a number of new and experimental medications. In the current era, mechanical circulatory support has been gaining a stronger presence in critical care and can be used in cardiogenic shock of the pregnant patient refractory to medical therapy. We discuss medical therapies, mechanical circulatory support, arrhythmia management, and a delivery plan in the setting of cardiogenic shock secondary to PPCM.

Abstract
INTRODUCTION It is well established that women with very high risk of developing antenatal thrombosis benefit from high-dose thromboprophylaxis, however data on outcomes and the safety and efficacy of thromboprophylaxis are scarce. The aim of the study was to evaluate the safety and effectiveness of the Swedish guidelines for high-dose thromboprophylaxis and the obstetric outcomes in a single-center patient cohort. PATIENTS AND METHODS Forty-seven women treated at the Department of Obstetrics and Gynecology, Karolinska University Hospital, Solna, Sweden, between 2004 and 2017 were included in this retrospective study. Data on treatment, obstetric, and neonatal outcomes and medical history were collected. Data derived from the Swedish Medical Birth Registry on women giving birth in Stockholm County 2004-2016 were used as controls. The protocol of the study was approved by the Regional Ethics Committee in Stockholm, Sweden. RESULTS The initial thromboprophylaxis dose was 5000 IU dalteparin twice daily. No patient developed ablatio placentae or preeclampsia. One patient suffered antenatal muscle vein thrombosis. Six patients (12.7%) suffered postpartum hemorrhage (PPH); however only one patient had severe PPH. Forty-eight children were born. Three children (6%) were diagnosed with intrauterine growth retardation, five (10%) were born small for gestational age and seven (15%) were born premature, the majority of which (except for two premature) to women with thrombophilia. DISCUSSION High-dose thromboprophylaxis was effective and safe. The incidence of preeclampsia and ablatio was lower than in controls; however, neonatal outcomes were worse, especially among mothers with thrombophilia. Due to the diversity of the thrombophilic traits, no thrombophilia-specific conclusion could be drawn. Stricter adherence to the guidelines could further decrease the risk for bleeding, whereas more frequent antenatal controls could possible improve neonatal outcomes.

Abstract
Peripartum cardiomyopathy (PPCM) is a rare, often dilated, cardiomyopathy with systolic dysfunction that presents in late pregnancy or, more commonly, the early postpartum period. Although the condition is prevalent worldwide, women with black ancestry seem to be at greatest risk, and the condition has a particularly high incidence in Nigeria and Haiti. Other risk factors include pre-eclampsia, advanced maternal age, and multiple gestation pregnancy. Although the complete pathophysiology of peripartum cardiomyopathy remains unclear, research over the past decade suggests the importance of vasculo-hormonal pathways in women with underlying susceptibility. At least some women with the condition harbor an underlying sarcomere gene mutation. More than half of affected women recover systolic function, although some are left with a chronic cardiomyopathy, and a minority requires mechanical support or cardiac transplantation (or both). Other potential complications include thromboembolism and arrhythmia. Currently, management entails standard treatments for heart failure with reduced ejection fraction, with attention to minimizing potential adverse effects on the fetus in women who are still pregnant. Bromocriptine is one potential disease specific treatment under investigation. In this review, we summarize the current literature on peripartum cardiomyopathy, as well as gaps in the understanding of this condition and future research directions.

Abstract
INTRODUCTION Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is the third most frequent cardiovascular disease besides myocardial infarction and stroke. Because DVT may cause life-threatening conditions, treatment should be started as soon as possible. This comprises certain challenges in special populations. Areas covered: In cancer-associated VTE, current treatment is different from non-cancer VTE due to disease-related interventions and higher bleeding risks. In the treatment of patients with extensive DVT, the role of catheter-directed thrombolysis has been investigated in two randomized trials, but results do not yield a recommendation for standard thrombolysis. The diagnosis of suspected recurrent DVT is especially challenging in case of ipsilateral DVT. Treatment strategies in recurrent DVT are dependent on the case and on particular risk factors. Also discussed is the therapy for DVT in pregnant women, which is more complex as a result of anticoagulants crossing the placenta. Expert commentary: DVT treatment in special populations poses special challenges due to high thrombotic and bleeding risk. This will be discussed in more detail in this review.

Abstract
PURPOSE OF REVIEW This manuscript addresses the risks for venous thromboembolism (VTE) during pregnancy and the associated challenges of both diagnosis and treatment. RECENT FINDINGS The obstacles to diagnosis given lack of specificity of typical biomarkers to predict VTE in pregnancy, as well as the unique fetal and bleeding risks introduced by managing massive pulmonary embolism (PE) with thrombolytics or thrombectomy are highlighted. VTE during pregnancy and the postpartum window occurs at a 6-10-fold higher rate compared with age-matched peers and is a major cause of morbidity and mortality. Hypercoagulability persists for 6-8 weeks after delivery with the highest risk of PE being postpartum. The lack of randomized trials in pregnant women leads to variability in practice, which are largely based on expert consensus or extrapolation from non-pregnant cohorts. The standard treatment of VTE in pregnancy is anticoagulation with low molecular weight heparin (LMWH), which like unfractionated heparin does not cross the placenta and is not teratogenic. LMWH is preferred given the negligible risk for heparin-induced thrombocytopenia and osteoporosis, better bioavailability, and a predictive dose response. Depending on the severity of the VTE, additional treatments including thrombolysis, thrombectomy, inferior vena cava filter placement, or venous stenting may be used. Management requires balancing the competing bleeding and thrombotic risks during labor and delivery and factoring the impact of treatment on the fetus. A multidisciplinary team involving hematology, obstetrics, anesthesia, vascular medicine, and cardiology is critical for safe and timely management. The design and execution of prospective, randomized trials to specifically address optimal diagnosis and management are a top priority in obstetric hematology.

Abstract
INTRODUCTION This review aims to summarize challenges in clinical management of concomitant gliomas and pregnancy and provides suggestions for this management based on current literature. METHODS PubMed and Embase databases were systematically searched for studies on glioma and pregnancy. Observational studies and articles describing expert opinions on clinical management were included. The strength of evidence was categorized as arguments from observational studies, consensus in expert opinions, or single expert opinions. Risk of bias was assessed by the Newcastle-Ottawa Scale (NOS). RESULTS 27 studies were selected, including 316 patients with newly diagnosed (n = 202) and known (n = 114) gliomas during pregnancy. The median sample size was 6 (range 1-65, interquartile range 1-9). Few recommendations originated from observational studies; the remaining arguments originated from consensus in expert opinions. CONCLUSION Findings from observational studies of adequate quality include (1) There is no known effect of pregnancy on survival in low-grade glioma patients; (2) Pregnancy can provoke clinical deterioration and tumor growth on MRI; (3) In stable women at term, there is no benefit of cesarean section over vaginal delivery, with respect to adverse events in mother or child. Unanswered questions include when pregnancy should be discouraged, what best monitoring schedule is for both mother and fetus, and if and how chemo- and radiation therapy can be safely administered during pregnancy. A multicenter individual patient level meta-analysis collecting granular information on clinical management and related outcomes is needed to provide scientific evidence for clinical decision-making in pregnant glioma patients.
