Peripartum ventricular tachycardia and PVC-induced cardiomyopathy: delivering optimal care when it's time to deliver.

Ventricular tachycardia (VT) is a rare but potentially fatal complication in pregnancy. We present a case of a pregnant woman with cardiomyopathy due to frequent premature ventricular complexes (PVCs) and VT originating from the left ventricular outflow tract. After presenting late in the third trimester, the decision was made to deliver the fetus after 4 days of medication titration due to continued sustained episodes of VT. After delivery, the patient continued to have frequent PVCs and VT several months after discharge, and she ultimately underwent a PVC ablation with dramatic reduction in PVC burden and improvement in cardiomyopathy. Multidisciplinary planning with a pregnancy heart team led to appropriate contingency planning and a successful delivery. This case highlights how multidisciplinary management is best practice in pregnancy complicated by VT and the need for better diagnostic guidelines for PVC-induced cardiomyopathy in the setting of pregnancy.

Health Service Use and Costs During Pregnancy Among Privately Insured Individuals With Congenital Heart Disease.

Importance: Individuals with congenital heart disease (CHD) are increasingly reaching childbearing age, are more prone to adverse pregnancy events, and uncommonly undergo recommended cardiac evaluations. Data to better understand resource allocation and financial planning are lacking. Objective: To examine health care use and costs for patients with CHD during pregnancy. Design, Setting, and Participants: This retrospective cohort study was performed from January 1, 2010, to December 31, 2016, using Merative MarketScan commercial insurance data. Participants included patients with CHD and those without CHD matched 1:1 by age, sex, and insurance enrollment year. Pregnancy claims were identified for all participants. Data were analyzed from September 2022 to March 2024. Exposures: Baseline characteristics (age, US region, delivery year, insurance type) and pregnancy-related events (obstetric, cardiac, and noncardiac conditions; birth outcomes; and cesarean delivery). Main Outcomes and Measures: Health service use (outpatient physician, nonphysician, emergency department, prescription drugs, and admissions) and costs (total and out-of-pocket costs adjusted for inflation to represent 2024 US dollars). Results: A total of 11 703 pregnancies (mean [SD] maternal age, 31.5 [5.4] years) were studied, with 2267 pregnancies in 1785 patients with CHD (492 pregnancies in patients with severe CHD and 1775 in patients with nonsevere CHD) and 9436 pregnancies in 7720 patients without CHD. Compared with patients without CHD, pregnancies in patients with CHD were associated with significantly higher health care use (standardized mean difference [SMD] range, 0.16-1.46) and cost (SMD range, 0.14-0.55) except for out-of-pocket inpatient and ED costs. After adjustment for covariates, having CHD was independently associated with higher total (adjusted cost ratio, 1.70; 95% CI, 1.57-1.84) and out-of-pocket (adjusted cost ratio, 1.40; 95% CI, 1.22-1.58) costs. The adjusted mean total costs per pregnancy were $15 971 (95% CI, $15 480-$16 461) for patients without CHD, $24 290 (95% CI, $22 773-$25 806) for patients with any CHD, $26 308 (95% CI, $22 788-$29 828) for patients with severe CHD, and $23 750 (95% CI, $22 110-$25 390) for patients with nonsevere CHD. Patients with vs without CHD incurred $8319 and $700 higher total and out-of-pocket costs per pregnancy, respectively. Conclusions and Relevance: This study provides novel, clinically relevant estimates for the cardio-obstetric team, patients with CHD, payers, and policymakers regarding health care and financial planning. These estimates can be used to carefully plan for and advocate for the comprehensive resources needed to care for patients with CHD.

Haemorrhagic stroke in pregnancy.

OBJECTIVE: To present a case of acute haemorrhagic stroke during 3rd trimester of pregnancy and to describe management and successful delivery of healthy baby. CASE REPORT: Haemorrhagic stroke is responsible for significant morbidity and mortality. Prognosis can be improved only by urgent diagnosis and care. We report a case of pregnant woman at 37th week of pregnancy with acute haemorrhagic stroke of unknown etiology with clinical appearance of thunderclap headaches and overall disorientation. We describe diagnostic approach and a successful management followed by further differential diagnosis and treatment. The foetus was delivered by acute caesarean section at 37th week of pregnancy. CONCLUSION: Occurrence of haemorrhagic stroke in pregnancy is rare. There are no specific guidelines that recommend the time and mode of delivery; therefore, each case is assessed individually.

Cardiovascular Complications With Delivery Hospitalizations in Patients With Pulmonary Hypertension: A Nationwide Study From 2011 to 2020.

BACKGROUND: Pregnancy in patients with pulmonary hypertension (PH) is associated with a heightened risk of medical complications including right heart failure, pulmonary edema, and arrhythmias. Our study investigated the association between PH and these complications during delivery. METHODS AND RESULTS: The National Inpatient Sample was used to identify delivery hospitalizations from 2011 to 2020. Multivariable logistic regression was performed to study the association of PH with the primary outcomes of in-hospital medical and obstetric complications. A total of 37 482 207 delivery hospitalizations in women ≥18 years of age were identified, of which 9593 patients had PH. Pregnant patients with PH had higher incidence of complications during delivery including preeclampsia/eclampsia, arrhythmias, and pulmonary edema among others, compared with those without PH. Pregnant patients with PH also had a higher incidence of in-hospital mortality compared with those without PH (0.51% versus 0.007%). In propensity-matched analyses, PH was still significantly associated with a higher risk of in-hospital mortality (odds ratio [OR], 5.02 [95% CI, 1.82-13.90]; P=0.001), pulmonary edema (OR, 9.11 [95% CI, 6.34-13.10]; P<0.001), peripartum cardiomyopathy (OR, 1.85 [95% CI, 1.37-2.50]; P<0.001), venous thromboembolism (OR, 12.60 [95% CI, 6.04-26.10]; P<0.001), cardiac arrhythmias (OR, 6.11 [95% CI, 4.97-7.53]; P<0.001), acute kidney injury (OR, 3.72 [95% CI, 2.86-4.84]; P<0.001), preeclampsia/eclampsia (OR, 2.24 [95% CI, 1.95-2.58]; P<0.001), and acute coronary syndrome (OR, 2.01 [95% CI, 1.06-3.80]; P=0.03), compared with pregnant patients without PH. CONCLUSIONS: Delivery hospitalizations in patients with PH are associated with a high risk of mortality, pulmonary edema, peripartum cardiomyopathy, venous thromboembolism, arrhythmias, acute kidney injury, preeclampsia/eclampsia, and acute coronary syndrome.

Management of hypertensive disorders in pregnancy: a Position Statement of the European Society of Hypertension Working Group 'Hypertension in Women'.

Hypertensive disorders in pregnancy (HDP), remain the leading cause of adverse maternal, fetal, and neonatal outcomes. Epidemiological factors, comorbidities, assisted reproduction techniques, placental disorders, and genetic predisposition determine the burden of the disease. The pathophysiological substrate and the clinical presentation of HDP are multifarious. The latter and the lack of well designed clinical trials in the field explain the absence of consensus on disease management among relevant international societies. Thus, the usual clinical management of HDP is largely empirical. The current position statement of the Working Group 'Hypertension in Women' of the European Society of Hypertension (ESH) aims to employ the current evidence for the management of HDP, discuss the recommendations made in the 2023 ESH guidelines for the management of hypertension, and shed light on controversial issues in the field to stimulate future research.

Management of non-cirrhotic variceal bleeding in pregnant women with Budd-Chiari syndrome in the early second trimester: A case report.

Budd-Chiari syndrome is one of the post-hepatic causes of portal hypertension and a potential obstruction causes liver fibrosis. In pregnancy, obstruction of hepatic veins could occur due to stenosis or thrombosis. Variceal bleeding is the most fatal complication in pregnancy with co-existing Budd-Chiari syndrome, with 29.4% incidence of abortion and 33.3% perinatal mortality. The aim of this case report was to present the management of non-cirrhotic variceal bleeding in pregnant women with Budd-Chiari syndrome in the early second trimester. We report a pregnant female at 13-14 weeks gestation presented to the hospital with profuse hematemesis. Doppler ultrasonography (USG) was utilized to confirm the diagnosis of Budd-Chiari syndrome-hepatic vein occlusion type in pregnancy. Abdominal USG revealed hepatomegaly with hepatic veins dilation, while endoscopy showed grade IV esophageal varices and grade IV gastric varices. Laboratory results indicated disseminated intravascular coagulation due to hemorrhage. The patient was given strict fluid resuscitation and three packed red cells transfusion to stabilize the hemodynamic. Bleeding was successfully managed by intravenous octreotide, tranexamic acid, and vitamin K. The case highlights that the management of non-cirrhotic variceal bleeding in pregnancy with Budd-Chiari syndrome requires a multidisciplinary approach and regular fetal monitoring to ensure optimal outcomes.

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.

High-Risk Congenital Heart Disease in Pregnancy.

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

Valvular Heart Disease in Pregnancy.

Valvular heart disease is a common cause of peripartum cardiovascular morbidity and mortality. The hemodynamic changes of pregnancy and their impact on preexisting valvular lesions are described in this paper. Tools for calculation of maternal and fetal risk during pregnancy are also discussed. The pathophysiology and management of valvular lesions, both obstructive and regurgitant, are then described, followed by discussion of mechanical and bioprosthetic valve complications during pregnancy.

Development and implementation of a pregnancy heart team at a Southeastern United States tertiary hospital: a qualitative study.

BACKGROUND: The United States has seen a significant rise in maternal mortality and morbidity associated with cardiovascular disease over the past 4 decades. Contributing factors may include an increasing number of parturients with comorbid conditions, a higher rate of pregnancy among women of advanced maternal age, and more patients with congenital heart disease who survive into childbearing age and experiencing pregnancy. In response, national medical organizations have recommended the creation of multidisciplinary obstetric-cardiac teams, also known as pregnancy heart teams, to provide comprehensive preconception counseling and coordinated pregnancy management that extend through the postpartum period. OBJECTIVE: We sought to describe the development and implementation of a pregnancy heart team for parturients with cardiac disease at a southeastern United States tertiary hospital. STUDY DESIGN: This was a qualitative study that was conducted among healthcare team members involved during the pregnancy heart team formation. Semi-structured interviews were conducted between April and May 2022, professionally transcribed, and the responses were thematically coded for categories and themes using constructs from The Consolidated Framework for Implementation Research. RESULTS: Themes identified included intentional collaboration to improve outpatient and inpatient coordination through earlier awareness of patients who meet the criteria and via documented care planning. The pregnancy heart team united clinicians around best practices and coordination to promote the success and safety of pregnancies and not only to minimize maternal health risks. Developing longitudinal care plans was critical among the pathway team to build on collective expertise and to provide clarity for those on shift to reduce hesitancy and achieve timely, vetted practices without additional consults. Establishing a proactive approach of specialists offering their perspectives was viewed as positively contributing to a culture of speaking up. Barriers to the successful development and sustainability of the pregnancy heart team included unmet administrative needs and clinician turnover within a context of shortages in staffing and high workload. CONCLUSION: This study described the process of developing and implementing a pregnancy heart team at 1 institution, thereby offering insights for future multidisciplinary care for maternal cardiac patients. Establishing pregnancy heart teams can enhance quality care for high-risk patients, foster learning and collaboration among physician and nursing specialties, and improve coordination to manage complex maternal cardiac cases.

Peripartum cardiomyopathy: A case report of decompensated heart failure in a hypertensive patient.

RATIONALE: Peripartum cardiomyopathy (PPCM) occurring in the context of hypertension presents a unique clinical challenge. This case contributes to the medical literature by highlighting the complexities of managing heart failure in postpartum women with pre-existing hypertensive disorders, particularly when complicated by a history of preeclampsia. PATIENT CONCERNS: Mrs. O.O., a 34-year-old hypertensive woman, presented with progressive dyspnea, bilateral leg swelling, and orthopnea. Notably, she had a history of previous preeclampsia and exhibited worsening symptoms over several months. DIAGNOSES: The patient was diagnosed with decompensated heart failure secondary to PPCM, exacerbated by hypertension and anemia. INTERVENTIONS: Therapeutic interventions included diuretics, angiotensin receptor-neprilysin inhibitors, digoxin, and anticoagulation. Additionally, lifestyle modifications and dietary restrictions were implemented. OUTCOMES: Following treatment adjustments, the patient demonstrated significant improvement in symptoms, exercise tolerance, and cardiac function. The transition from NYHA class III to class II heart failure indicated successful management. LESSONS: This case underscores the importance of a comprehensive approach to managing PPCM in hypertensive patients, with attention to cardiovascular and obstetric factors. It highlights the effectiveness of multidisciplinary care in achieving positive outcomes and emphasizes the need for heightened vigilance in postpartum women with cardiovascular risk factors.

Acute Coronary Syndrome in Women: An Update.

PURPOSE OF REVIEW: The goal of this manuscript is to provide a concise summary of recent developments in the approach to and treatment of women with acute coronary syndrome (ACS). RECENT FINDINGS: This review covers terminology updates relating to ACS and myocardial injury and infarction. Updates on disparities in recognition, treatments, and outcomes of women with ACS due to atherosclerotic coronary artery disease are covered. Other causes of ACS, including spontaneous coronary artery dissection and myocardial infarction with non-obstructive coronary artery disease are discussed, given the increased frequency in women compared with men. The review summarizes the latest on the unique circumstance of ACS in women who are pregnant or post-partum, including etiologies, diagnostic approaches, medication safety, and revascularization considerations. Compared with men, women with ACS have unique risk factors, presentations, and pathophysiology. Treatments known to be effective for men with atherosclerosis-related ACS are also effective for women; further work remains on reducing the disparities in diagnosis and treatment. Implementation of multimodality imaging will improve diagnostic accuracy and allow for targeted medical therapy in the setting of myocardial infarction with non-obstructive coronary artery disease.

Clinical Trials That Have Changed Obstetric Practice: The Chronic Hypertension and Pregnancy (CHAP) Trial.

We describe the evolution of treatment recommendations for chronic hypertension (CHTN) in pregnancy, the CHTN and pregnancy (CHAP) trial, and its impact on obstetric practice. The US multicenter CHAP trial showed that antihypertensive treatment for mild CHTN in pregnancy [blood pressures (BP)<160/105 mm Hg] to goal<140/90 mm Hg, primarily with labetalol or nifedipine compared with no treatment unless BP were severe reduced the composite risk of superimposed severe preeclampsia, indicated preterm birth <35 weeks, placental abruption, and fetal/neonatal death. As a result of this trial, professional societies in the United States recommended treatment of patients with CHTN in pregnancy to BP goal<140/90 mm Hg.

Bridging gaps: The urgent call for cardio-obstetrics as a subspecialty in India.

Cardiovascular disease complicates 1-4% of pregnancies. Women with heart disease going through pregnancy are on the increase. While global maternal deaths during pregnancy are decreasing, India remains a significant contributor to maternal deaths in the world. Cardiovascular disease during pregnancy is the leading cause of maternal mortality in developed nations, and this trend is expected soon in India, with the ongoing obstetric transition. Research in developed nations indicates that a high proportion of maternal mortality related to heart disease is preventable. However, India lacks indigenous data, risk stratification tools, management guidelines, and a well-defined cardio-obstetric team concept for pregnant women with heart disease. There is a pressing need to establish national registries, develop risk stratification tools, develop and disseminate management guidelines, and create dedicated cardio-obstetric programs. This article provides a comprehensive overview of this requirement and offers solutions to bridge the existing gaps in India's maternal healthcare landscape.
