Abstract
We discuss a case where the blood cultures of a patient with clinical chorioamnionitis and elevated D-dimer levels enabled early diagnosis of infective endocarditis. A 31-year-old female with a 39-week pregnancy presented to the obstetrics department with a fever. Cardiotocography revealed fetal tachycardia and severe late deceleration. Preoperative examinations revealed a leukocyte count of 15,900/μL and D-dimer levels of 86.2 μg/mL. She was diagnosed with a non-reassuring fetal status due to clinical chorioamnionitis; accordingly, an emergency cesarean section was performed. Imaging studies ruled out the possibility of a thromboembolism. Subsequent maternal blood cultures were positive for Staphylococcus aureus. Echocardiography revealed vegetation on the aortic valve, leading to a diagnosis of infective endocarditis. Blood cultures can be useful in evaluating for sepsis in cases of clinical chorioamnionitis with elevated D-dimer levels as they may facilitate early diagnosis of infective endocarditis during pregnancy.

Abstract
OBJECTIVE Pregnancy-related infective endocarditis (IE) caries a high risk of morbidity and mortality. With increasing intravenous drug abuse (IVDA) amid the opioid epidemic, the risk factor profile may be shifting. In this case series, we aimed to describe risk factors and outcomes for peripartum IE in a contemporary cohort. STUDY DESIGN We identified patients with IE diagnosed during pregnancy or up to 6 weeks' postpartum from 2015 through 2018 at a single tertiary care center. We abstracted detailed medical history and clinical outcome measures from the electronic medical record. The diagnosis of IE was supported by the modified Duke Criteria. RESULTS Nine patients had peripartum IE: eight (89%) with a history of IVDA, one with an indwelling central venous catheter (11%), and one with prior IE (11%). None had preexisting congenital or valvular heart disease. Six (67%) had comorbid hepatitis C. Eight cases (89%) had gram-positive cocci with vegetations involving the tricuspid valve (56%) and both mitral and tricuspid valves (22%). Major complications included shock (33%), mechanical ventilation (44%), septic emboli (67%), and noncardiac abscesses (33%). Two patients underwent valve surgery, and there were two cases of postpartum maternal mortality (22%), one from septic shock and one from intracerebral hemorrhage. While four patients (44%) delivered preterm (average gestational age 35 weeks), most delivered vaginally (89%) with only one requiring an emergent caesarean section. There was no fetal mortality, although three newborns (43%) required admission to the neonatal intensive care unit. Two patients were initiated on medication-assisted treatment for opioid use disorder. Consultants included infectious disease, cardiology, cardiac surgery, maternal-fetal medicine, and psychiatry. CONCLUSION These findings confirm that IVDA is a growing risk factor for pregnancy-related IE. Peripartum IE carries a high risk of complications, including maternal mortality, and warrants management with a multidisciplinary care team at a tertiary center. KEY POINTS · Intravenous drug use was the most common risk factor for IE in pregnancy.. · IE in pregnancy carries a high morbidity and mortality with complications including septic emboli, septic shock, and need for mechanical ventilation.. · A multidisciplinary team approach can assure the best possible maternal and fetal outcomes..

Abstract
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.

Abstract
The diagnosis of infective endocarditis (IE) during pregnancy is accompanied by a poor prognosis for both mother and fetus in the absence of prompt management by multidisciplinary teams. We searched the electronic databases of PubMed, MEDLINE and EMBASE for clinical studies addressing the management of infective endocarditis during pregnancy, with the aim of realizing a literature review ranging from risk factors to diagnostic investigations to optimal therapeutic management for mother and fetus alike. The presence of previous cardiovascular pathologies such as rheumatic heart disease, congenital heart disease, prosthetic valves, hemodialysis, intravenous catheters or immunosuppression are the main risk factors predisposing patients to IE during pregnancy. The identification of modern risk factors such as intracardiac devices and intravenous drug administration as well as genetic diagnostic methods such as cell-free deoxyribonucleic acid (DNA) next-generation sequencing require that these cases be addressed in multidisciplinary teams. Guiding treatment to eradicate infection and protect the fetus simultaneously creates challenges for cardiologists and gynecologists alike.

Abstract
Postpartum infective endocarditis is a rare disease, especially in people with no risk factors (ie, intravenous drug use), that can be followed by severe morbidity and mortality. Here, we report a case of postpartum infective endocarditis with an unusual acute coronary syndrome-like presentation in a patient with minimal risk factors. In addition to lesions on the aortic valve causing severe aortic insufficiency, the patient's case was also complicated by left main coronary artery embolization, which was subsequently aspirated during surgery. Repeat angiography demonstrated complete removal, with no evidence of downstream embolization.

Abstract
Abstract
Background
Although infective endocarditis (IE) in pregnancy is rare, maternal and foetal mortality rates are very high. We herein report the successful treatment of a case of IE with simultaneous emergent caesarean section and mitral valve replacement performed at 27 weeks of gestation.
Case summary
A 29-year-old woman at 27 weeks of gestation was referred for congestive heart failure (HF) due to infective endocarditis (IE) with large mobile vegetations and overt disruption of the mitral valve. We held a multi-disciplinary conference and decided to perform mitral valve replacement immediately after caesarean section because of the high risk of embolism and sepsis, worsening and unstable haemodynamics, and sufficient foetal maturity for delivery. Although coronary artery embolization and asymptomatic multiple cerebral infarctions were observed, her post-operative course was uneventful. Ultimately, the patient was discharged 29 days after surgery. The neonate was treated in the NICU until the expected delivery date and was discharged home on Day 95 of life.
Discussion
Difficulties are associated with the selection of an operative plan and its timing for IE during pregnancy. Heart failure due to IE requires urgent surgery when medical treatment cannot stabilize the patient. However, cardiopulmonary bypass and medicine for pregnant women adversely affect the foetus. Therefore, the timing of surgery and delivery needs to be selected by a multi-disciplinary team and in consideration of the maternal condition and foetal maturity.

Abstract
This report describes a challenging obstetric case in which septic emboli from Streptococcus oralis endocarditis subsequently led to central nervous system infection. There were delays in diagnosis as the patient presented with non-specific symptoms of fever, diarrhoea and vomiting, initially suspected to be due to viral gastroenteritis and later SARS-CoV-2 infection. Antibiotics were commenced once gram positive cocci were isolated from a blood culture. The patient made no significant improvement despite antimicrobial therapy and subsequently developed a worsening headache and delirium. This deterioration was not rapidly recognised despite the use of a routine obstetric early warning score. However, a diagnosis of meningitis was made once the potential severity of the patient's condition was recognised and Streptococcus oralis was identified in cerebrospinal fluid and blood cultures. Bacterial endocarditis was diagnosed following transthoracic echocardiography. The patient improved with optimised antimicrobial therapy and delivered a healthy baby. This example highlights how non-specific symptoms can be caused by rare and life-threatening illnesses, and emphasises that early warning scores might not easily identify neurological deterioration in obstetric patients.

Abstract
Introduction Due to high levels of intravenous drug use (IVDU) in West Virginia (WV), there are increasing numbers of hospitalizations for infective endocarditis (IE). More specifically, pregnant patients with IE are a uniquely challenging population, with complex management and a clinical course that further affects the health of the fetus, with high morbidity and mortality. Timely recognition and awareness of the most common bacterial causes will provide hospitals and clinicians with valuable information to manage future patients. Methods This retrospective study analyzed the clinical course of pregnant patients admitted with IE and IVDU history presenting at Cabell Huntington Hospital from 2013 to 2018. Inclusion criteria were women between 16 and 45 years of age confirmed to be pregnant by urine pregnancy test and ultrasonography with at least eight weeks gestation, with a first-time diagnosis of endocarditis and an identified history of IVDU. We excluded charts with pre-existing risk factors including a history of valvular disease, rheumatic heart disease, surgical valve repair or mechanical valve replacement, or a diagnosis of coagulopathies. The resulting charts were evaluated for isolated organisms, reported clinical course, and complications of the pregnancy. Results A total of 10 patients were identified, with methicillin-susceptible and methicillin-resistant Staphylococcus aureus, Serratia marcescens, Haemophilus parainfluenza, and Enterococcus faecalis species. Complications included loss of fetus (30%), septic embolization (40%), hemorrhagic stroke (10%), and transfer to outside facilities for cardiothoracic surgical intervention (40%). Discussion IE in pregnancy, while rare, has serious complications. In the context of the IVDU epidemic, it has an increasing impact on WV hospitals. A better understanding of the clinical course may allow for early diagnosis and guide the development of rational empiric therapies. More effective management of IE in pregnant patients can reduce complications and potentially improve maternal and fetal morbidity or mortality.

Abstract
INTRODUCTION Infective endocarditis (IE) is a rare but serious infection complicating pregnancy. Little is known about IE management and outcomes in this population. METHODS The National Readmissions Database was used to obtain data between October 2015 and October 2018. Billing codes identified admissions for IE in female patients of reproductive age. Demographic characteristics, comorbidities, and outcomes were compared between a) patients with maternity-associated and non-maternity associated IE, and b) obstetric patients who delivered with and without IE. Weighted regressions were used to examine outcomes in adjusted models. RESULTS We identified 12,602 reproductive-aged female patients with a diagnosis of IE, of which 382 (weighted national estimate: 748) were maternity-associated. Of these cases, 117 (weighted national estimate: 217) occurred during a delivery admission. Compared to patients with non-maternity-associated IE, maternity-associated infection was associated with younger age (mean 29.0 vs. 36.6 years, P < 0.001), Medicaid coverage (72.5% vs. 47.2%, P < 0.001), and drug use (76.2% vs. 59.8%, P < 0.001). Mortality was comparable (8.1% vs. 10.6%, aRR = 1.03, 95% CI 0.71-1.48). Compared to patients delivering without IE, IE complicating delivery was associated with worse maternal and fetal outcomes, including maternal mortality (17.2% vs. <0.01%, aRR = 323.32, 95% CI 127.74-818.37) and preterm birth (55.7% vs. 10.1%, aRR = 3.61, 95% CI 2.58-5.08). CONCLUSION Maternity-associated IE does not appear to confer additional risk for adverse outcome over non-maternity-associated infection. Patients delivering with IE have worse maternal and fetal outcomes than those whose deliveries are not complicated by IE.

Abstract
BACKGROUND Endocarditis during pregnancy carries a maternal mortality of up to 30%, but prior publications do not reflect the current opioid epidemic. CASE PRESENTATIONS We reviewed our institution's infective endocarditis registry from 2009 to 2019 and identified 19 females with endocarditis during pregnancy in order to compare our contemporary outcomes with historical reports. In our cohort, intravenous drug use was reported in all cases, and the most common pathogen was Staphylococcus (74%) followed by Serratia (13%). The tricuspid valve was involved in 18 (95%) patients, and contrary to prior reports, all but two patients were managed conservatively with antibiotics alone. Maternal and infant mortality (5% and 0%, respectively) were lower in our cohort compared to all previous reviews. CONCLUSION We conclude that the better outcomes seen in this report are likely due to the younger age of the patients and the more frequent right-sided valvular involvement. SUMMARY This review highlights contemporary outcomes in endocarditis during pregnancy. We review historical case reports in light of the opioid epidemic. We observed more Staphylococcus, more right-sided valvular involvement, and more conservative management as well as improved maternal and foetal mortality.

Abstract
Objective An increase in opioid use disorder and subsequent intravenous drug use has led to an increase in sequalae that may complicate pregnancy, such as infective endocarditis. Infective endocarditis has the potential for significant maternal and neonatal morbidity and mortality. We sought to examine the management considerations and clinical implications of intravenous drug use-related infective endocarditis in pregnancy from our center's experience. Study Design Retrospective study of management of pregnancies complicated by infective endocarditis as a result of active intravenous drug use at an academic tertiary care hospital from January 2012 through December 2019. Results Twelve women with active intravenous drug use histories were identified as having clinical and echocardiographic features consistent with infective endocarditis. Six women were discharged against medical advice and did not complete the full course of recommended antibiotic regimen. Eight women were started or continued on opioid agonist therapy during their hospitalization. Four neonates required neonatal intensive care unit admission for pharmacologic treatment for neonatal abstinence syndrome. Conclusion Management of intravenous drug use-associated infective endocarditis in pregnancy involves more than treating the acute condition. In pregnant women with opioid use disorder and infective endocarditis, addiction and chronic psychosocial conditions need to be addressed to optimize care.

Abstract
Background Sepsis is an important cause of morbidity and mortality in the pregnant patient. Injection drug use in pregnant populations has led to increased cases of bacteremia and infective endocarditis (IE) due to Staphylococcus aureus. We describe all cases of S. aureus bacteremia and IE among admitted pregnant patients at our hospital over a 6-year period. Methods This was a retrospective review of pregnant patients hospitalized with S. aureus bacteremia between April 2013 and November 2019. Maternal in-hospital mortality and fetal in-hospital mortality were the primary outcomes measured; the secondary outcome was the rate of 6-month maternal readmission. Results Twenty-seven patients were included; 15 (56%) had IE. The median (interquartile range [IQR]) age was 29 (25-33) years; 22 (82%) patients had methicillin-resistant S. aureus. Infection onset occurred at a median (IQR) of 29 (23-34) weeks' gestation. Twenty-three (85%) mothers reported active injection drug use, and 21 (78%) were hepatitis C seropositive. Fifteen (56%) mothers required intensive care unit (ICU) care. Twenty-two (81%) patients delivered 23 babies; of the remaining 5 mothers, 3 (11%) were lost to follow-up and 2 (7%) terminated pregnancy. Sixteen (73%) babies required neonatal ICU care, and 4/25 (16%) infants/fetuses died during hospitalization. One (4%) mother died during hospitalization, and 7/26 (27%) mothers were readmitted to the hospital within 6 months for infectious complications. Conclusions Injection drug use is a modifiable risk factor for S. aureus bacteremia in pregnancy. Fetal outcomes were poor, and mothers were frequently readmitted secondary to infection. Future targeted interventions are needed to curtail injection drug use in this population.

Abstract
Cardiovascular disease complicates 1-4% of pregnancies - with a higher prevalence when including hypertensive disorders - and is the leading cause of maternal death. In women with known cardiovascular pathology, such as congenital heart disease, timely counselling is possible and the outcome is fairly good. By contrast, maternal mortality is high in women with acquired heart disease that presents during pregnancy (such as acute coronary syndrome or aortic dissection). Worryingly, the prevalence of acquired cardiovascular disease during pregnancy is rising as older maternal age, obesity, diabetes mellitus and hypertension become more common in the pregnant population. Management of cardiovascular disease in pregnancy is challenging owing to the unique maternal physiology, characterized by profound changes to multiple organ systems. The presence of the fetus compounds the situation because both the cardiometabolic disease and its management might adversely affect the fetus. Equally, avoiding essential treatment because of potential fetal harm risks a poor outcome for both mother and child. In this Review, we examine how the physiological adaptations during pregnancy can provoke cardiometabolic complications or exacerbate existing cardiometabolic disease and, conversely, how cardiometabolic disease can compromise the adaptations to pregnancy and their intended purpose: the development and growth of the fetus.

Abstract
Infective endocarditis (IE) during pregnancy and subsequent cardiac surgery are rare and associated with a high risk of mortality for the mother and fetus. It is difficult to determine the right time for cardiac intervention when IE is diagnosed early in pregnancy. A 33-year-old previously healthy woman in the 11th week of pregnancy was diagnosed with IE and underwent surgical intervention. The cardiopulmonary bypass settings and the anesthetic drugs were carefully chosen. Although she was in good health, while being discharged, the fetus did not survive. Anesthesiologists prioritizing the mother's survival should aim to improve fetal outcomes in such cases.

Abstract
Bacterial infective endocarditis is a rare but a life-threatening infection during pregnancy. Infective endocarditis during pregnancy is often associated with a congenital heart condition or an earlier history of rheumatic heart disease. In pregnant women with infective endocarditis, the maternal and fetal mortality rate can reach as high as 33% and 29%, respectively. In most cases, infective endocarditis runs a subacute course and involves the mitral valve, nonetheless, rarely it can involve the aortic valve as well. We are documenting a rare case of subacute infective endocarditis in a 26-year-old pregnant female with severe aortic stenosis with associated multiple systemic emboli. The patient was managed by urgent cesarean section at 35 weeks of gestation followed by aortic valve replacement; there was no maternal or fetal mortality. This case report highlights the importance of early diagnosis, and timely management of infective endocarditis in pregnant women to prevent maternal and fetal death.

Abstract
Under the circumstances of cardiovascular adaptations and immunomodulation, an uncommon but disastrous complication of infective endocarditis (IE) can occur in pregnancy. Almost all the cases reported earlier were caused by bacteria. We report a fatal case of zygomycotic valvular and mural endocarditis in a young non-diabetic primigravida with a positive hepatitis B serology.

Abstract
BACKGROUND Thrombotic thrombocytopenic purpura (TTP) is a life-threatening illness that occurs in both pregnant and non-pregnant women. Several other conditions can mimic the disease, which makes the diagnosis challenging. CASE We describe a case of severe Staphylococcus aureus endocarditis that initially presented as peripartum TTP in a 39-year-old woman at 29+6 weeks' gestation. We give an overview of the diagnostic considerations and management of thrombocytopenia in pregnancy and review the literature related to TTP and peripartum infective endocarditis. CONCLUSION Given the significant differences in definitive therapies for the spectrum of thrombocytopenic conditions that occur in pregnancy, timely and accurate diagnosis of TTP is critical for optimal management.

Abstract
Infective endocarditis during pregnancy carries a high mortality risk, both for the mother and for the foetus and requires a multidisciplinary team in the management of complicated cases. We report our experience with a 39-year old patient, affected by an acute active mitral endocarditis due to Abiotrophia defectiva at the 14th gestational week, strongly motivated to continue the pregnancy. Our patient successfully underwent mitral valve replacement with a normothermic high-flow cardiopulmonary bypass under continuous intraoperative foetal monitoring. Caesarean section occurred at the 38th gestational week. The delivery was uneventful and both the mother and child are doing well at the 16-month follow-up.

Abstract
Infective endocarditis in pregnancy is associated with high maternal and fetal morbidity and mortality and is estimated to complicate approximately 1 in 100,000 pregnancies. We report the case of a 33-year-old patient who presented at 30 weeks and 3 days gestation in her third pregnancy. The patient described a 3 week history of feeling generally unwell, an episode of temporary speech disturbance, right shoulder tip pain, left subscapular pain on inspiration and chest discomfort. Investigations included an echocardiogram, which revealed a large mobile mass on the aortic coronary cusp and a small mass on the non-coronary cusp. There was significant aortic regurgitation. Blood cultures were positive for staphylococcus lugdunensis. A diagnosis of infective endocarditis was made. The patient deteriorated, with worsening cardiac function, and proceeded to have a caesarean section on day 7 of admission. Her baby had multiple limb abnormalities, subsequently diagnosed as arthrogryposis multiplex congenita. Aortic valve replacement with a mechanical valve was then performed on day 3 post partum. The patient recovered well post operatively and was discharged home with her baby on day 45 post partum. The commonest complications of IE are congestive cardiac failure, perivalvular extension and systemic embolization. The management of infective endocarditis in pregnancy is similar to that of the non-pregnant however there is high foetal mortality associated with cardiopulmonary by-pass for cardiac surgery. The patient described here developed staphylococcus lugdunensis infective endocarditis, which is a rare but aggressive causative organism in infective endocarditis. Infective endocarditis in pregnancy is a rare but serious condition with significant fetal and maternal morbidity and mortality. Early diagnosis with a multidisciplinary team approach is essential to improve outcomes.

Abstract
The objective of this review was to describe the clinical characteristics, risk factors, and outcomes of infective endocarditis (IE) in pregnancy and the postpartum period. We conducted a systematic review of Ovid MEDLINE, Ovid Embase, Web of Science, and Scopus from January 1, 1988, through October 31, 2012. Included studies reported on women who met the modified Duke criteria for the diagnosis of IE and were pregnant or postpartum. We included 72 studies that described 90 cases of peripartum IE, mostly affecting native valves (92%). Risk factors associated with IE included intravenous drug use (14%), congenital heart disease (12%), and rheumatic heart disease (12%). The most common pathogens were streptococcal (43%) and staphylococcal (26%) species. Septic pulmonary, central, and other systemic emboli were common complications. Of the 51 pregnancies, there were 41 (80%) deliveries with survival to discharge, 7 (14%) fetal deaths, 1 (2%) medical termination of pregnancy, and 2 (4%) with unknown status. Maternal mortality was 11%. Infective endocarditis is a rare, life-threatening infection in pregnancy. Risk factors are changing with a marked decrease in rheumatic heart disease and an increase in intravenous drug use. The cases reported in the literature were commonly due to streptococcal organisms, involved the right-sided valves, and were associated with intravenous drug use.

Abstract
All women of child-bearing age suffering from congenital cardiac valve malformations or acquired valvular disease, pulmonary hypertension or arterial hypertension and who are at risk for coronary heart disease should receive early counseling and optimal treatment before pregnancy. They should be treated by an interdisciplinary team composed of gynecologists, cardiologists, geneticists and, if necessary, cardiac surgeons. This interdisciplinary approach should be used for all pregnant women with cardiac disease in order to minimize maternal and fetal mortality. As physicians will only rarely be confronted with such critically ill patients, guidelines and access to worldwide information from databanks are particularly important (http://www.safetus.com und http://www.emryotox.de).

Abstract
BACKGROUND Cardiovascular diseases arise during 0,2% to 4% of all pregnancies in the industrialized world. In Germany, this type of complication, which is sometimes lethal, affects approximately 30 000 pregnant women per year. METHODS We performed a simple literature search in the NCBI databases for publications that appeared from 2008 to 2010 and that contained the search terms "pregnancy" and one of the following: "valvular disease," "endocarditis," "coronary heart disease," "cardiomyopathy," "hypertension," "anticoagulation." We also took consideration of the relevant international medical society guidelines and of the new database of the Pharmakovigilanz- und Beratungszentrum für Embryonaltoxikologie in Berlin (Embryotox). RESULTS There is a rising incidence, not only of hypertension during pregnancy, but also of valvular heart disease during pregnancy. Severe valvular stenosis, particularly mitral stenosis, raises the risk of pulmonary edema and should be treated before pregnancy, by valvuloplasty or surgically. Women with high-grade valvular insufficiency and restricted left-ventricular function are at risk of heart failure. For women with mechanical heart valves, the type of anticoagulation during pregnancy must be discussed on an individual basis. Coumarin derivatives are associated with an elevated risk of hemorrhage as well as coumarin embryopathy; recent studies have shown that the latter risk is low and dose-dependent. Spontaneous dissection of the coronary arteries is best treated by catheter intervention with the implantation of a bare metal stent. CONCLUSION Women of child-bearing age who are at risk for, or already have, cardiovascular disease should receive early counseling and treatment, not just from their family physician, but from an interdisciplinary team composed of gynecologists, cardiologists, and, if necessary, cardiac surgeons.

Abstract
The number of women with serious (non-obstetric) systemic diseases achieving pregnancy and requiring obstetric anaesthetic management is increasing. The conditions that are most likely to cause maternal morbidity and mortality are cardiac disease, respiratory disease, neuromuscular disease, haematological disease, connective and metabolic diseases and psychiatric conditions including substance abuse. This article discusses the anaesthetic management of the pregnant mother with such serious systemic diseases.

Abstract
The 2007 American Heart Association guidelines for the prevention of infective endocarditis have dramatically reduced both the types of eligible procedures and the types of eligible cardiac lesions that require prophylaxis. Antibiotic prophylaxis to prevent infective endocarditis is not indicated for any patient undergoing obstetric and/or gynaecological procedures, not even for patients with underlying cardiac lesions with the highest risk of developing complications from endocarditis. This sharp departure from previously published guidelines relies on the recognition that endocarditis is more likely to develop from "randomly occurring" bacteremia (e.g., from brushing teeth) than from invasive procedures and that antibiotic prophylaxis has not been proven to be effective. A short discussion on enterococcal infections associated to obstetric and gynaecological procedures and therapeutic implications is presented.

Abstract
A 29-year-old woman was transferred at 31 weeks gestation for management of infective endocarditis (IE). Echocardiography demonstrated vegetations on aortic valve and severe mitral regurgitation. Blood cultures were positive for Streptococcus sanguis. Due to impending hemodynamic collapse, a cesarean section was performed followed by aortic valve replacement and mitral valve repair with a patch of bovine pericardium. At 10-month review, both mother and baby are doing well.

Abstract
Infective endocarditis during pregnancy is uncommon but very serious. A 31-year-old woman in the 36th week of second pregnancy was admitted to a hospital because of fever, weakness, chest pain, painful skin over her right leg and dyspnea. Transthoracic echocardiography showed aortic valve vegetation and severe aortic regurgitation. Transesophageal echocardiography revealed a 18 mmx6 mm mobile vegetation, attached to the right coronary cusp. Emergency cesarean section followed with a delivery of a healthy baby. Cardiopulmonary bypass with subsequent aortic replacement with bioprosthesis was initiated immediately after cesarean section. Early echocardiographic examination and 6 months after surgery revealed normal function of aortic valve bioprosthesis and normal LV function. Clinical recognition and early echocardiographic diagnosis followed urgent simultaneous cesarean section and aortic valve replacement was lifesaving for both mother and fetus.

Abstract
Maternal heart disease complicates 0.2 to 3% of pregnancies and is responsible for 10% to 25% of maternal deaths. Many healthy women manifest subtle signs of cardiac failure during uncomplicated pregnancy and birth. Classic symptoms of heart disease mimic common symptoms of late pregnancy, such as palpitations, shortness of breath with exertion, and occasional chest pain. A complete cardiovascular examination assists the healthcare team to fully assess and evaluate the pregnant woman with known heart disease. Detailed assessment of the woman throughout pregnancy may lead to initial discovery of heart disease. Compilation of these objective data with subjective functional capacities allows for risk stratification and assignment to a New York Heart Association functional classification.

Abstract
The proteolytic active sites of the 26S proteasome are sequestered within the central chamber of its 20S catalytic core particle. Access to this chamber is through a narrow channel defined by the outer alpha subunits. Free proteasome 20S core particles are found in an autoinhibited state in which the N-termini of neighboring alpha subunits are anchored by an intricate lattice of interactions blocking access to the channel. Entry of substrates into proteasomes can be enhanced by attachment of activators or regulatory particles. An important part of this activation is channel gating; regulatory particles rearrange the blocking residues to form an open pore and promote substrate entry into the proteolytic chamber. Interestingly, some substrates can open the entrance themselves and thus facilitate their own destruction. In this review, we will discuss the mechanisms proposed for channel gating and the interactions required to maintain stable closed and open conformations.
