Abstract
OBJECTIVE This study aims to compare the perinatal outcomes of pregnant women with heart disease and a healthy pregnant control group, as well as the maternal and newborn outcomes of pregnant women with congenital heart disease and acquired heart disease. MATERIAL METHOD Pregnant women with heart disease and healthy control pregnant women were included in this retrospective study. Sociodemographic data of all patients included in the study were obtained from electronic records. Perinatal outcomes of all patients were compared. RESULTS A total of 258 pregnant women were included in the study. While 129 pregnant women were diagnosed with heart disease, 129 patients were low-risk pregnant women. Preeclampsia (p=0.004) and cesarean section (p=0.01) rates were higher in pregnant women with heart disease compared to healthy pregnant women. Compared with healthy pregnant women, pregnant women with heart disease had a lower birth weight (p=0.003), a higher fetal growth restriction (FGR) rate (p=0.036), lower birth percentiles (p=0.002), a lower 5-minute APGAR (p=0.0001), a higher neonatal intensive care unit (NICU) admission rate (p=0.001), and a longer NICU stay rate (p=0.001). The mean gestational age at birth of pregnant women with congenital heart disease was higher than that of those with acquired heart disease (p=0.017). CONCLUSION It was observed that all maternal heart diseases were associated with adverse perinatal outcomes compared to healthy pregnant women. In this series, perinatal adverse outcomes of pregnant women with congenital and acquired heart disease did not differ.

Abstract
OBJECTIVES To investigate whether fetal cardiac function is affected by underlying heart disease in pregnant women. METHODS A total of 100 pregnant women who were ≥34 gestational weeks were included in the study, 40 in the maternal heart disease (MHD) group diagnosed with heart disease and 60 in the control group. All cardiac diseases in pregnant women were diagnosed preconceptionally and categorized according to the New York Heart Association (NYHA) classification system. Fetal cardiac functions of study groups were evaluated by M-mode, color tissue Doppler imaging (c-TDI), and pulsed wave Doppler. RESULTS Tricuspid annular plane systolic excursion and myocardial performance index (MPI) values were significantly higher and isovolumetric relaxation time was prolonged in the MHD group. The MPI value was found higher in MHD group with NYHA Class II compared to those with NYHA Class I. No significant change in any of the fetal tricuspid annular peak velocity values measured by c-TDI in the MHD group. There were no differences in fetal cardiac functions and perinatal outcomes between pregnant women with acquired and congenital heart diseases. Patients in NYHA Class II had lower birth weight, 1st and 5th minute APGAR scores, and higher neonatal intensive care unit admission rates. CONCLUSIONS Underlying heart diseases in pregnant women can cause alterations in the systolic and diastolic function of the fetal heart. High fetal MPI values detected in cardiac patients may indicate that cardiac pathologies during pregnancy affect fetal cardiac globular myocardial function. Cardiac pathologies that progress with restricted physical activity may cause changes in fetal cardiac function and may be associated with adverse perinatal outcomes.

Abstract
BACKGROUND Among cardiac causes for postpartum maternal collapse, severe mitral stenosis is not listed as a potential cause in current literature. We report a rare case of severe mitral stenosis that presented with severe hypoxia and maternal decompensation in early postpartum period for the first time. A 30-year-old para 2, abortus 1, Ethiopian woman developed severe hypoxia and rapid deterioration on her sixth postoperative day after cesarean delivery for fetal bradycardia with a good fetal outcome. She was put on a mechanical ventilator when she developed respiratory failure. Initially, a diagnosis of pulmonary embolus was considered. After admission to the intensive care unit, severe mitral stenosis was diagnosed with the help of echocardiography. She was managed successfully for congestive heart failure and discharged from the intensive care unit with improvement. CONCLUSION The possibility of mitral stenosis, as a differential diagnosis, should be considered whenever a case of postpartum maternal collapse is encountered. We recommend a routine immediate echocardiography in any patient that experiences postpartum collapse, especially in the presence of a known trigger for heart failure such as long hours of labor, bleeding, anemia, hypotension, and infection.

Abstract
Management of pregnant women with heart disease remains challenging due to the advancement of innovations in cardiac surgery and correction of complex cardiac anomalies, and more recently, with the successful performance of heart transplants, cardiac diseases are not only likely to coexist with pregnancy, but will also increase in frequency over the years to come. In developing countries with a higher prevalence of rheumatic fever, cardiac disease may complicate as many as 5.9% of pregnancies with a high incidence of maternal death. Since many of these deaths occur during or immediately following parturition, heart disease is of special importance to the anesthesiologist. This importance arises from the fact that drugs used for preventing or relieving pain during labor and delivery exert a major influence - for better or for worse - on the prognosis of the mother and newborn. Properly administered anesthesia and analgesia can contribute to the reduction of maternal and neonatal mortality and morbidity.

Abstract
Advances in the surgical palliation and correction of congenital heart lesions have improved survival and increased the number of patients living into adulthood. Although pregnancy outcomes will be favorable for most patients with congenital heart disease, the cardiovascular challenges associated with pregnancy and delivery are best managed with a multidisciplinary approach during the puerperium. This review addresses the prevalence, physiology, risk assessment, peripartum complications, and anesthetic management of the pregnant patient with underlying congenital heart disease.

Abstract
Infective endocarditis in pregnancy has a low incidence, often being associated with a previous history of rheumatic or congenital heart disease. In most reports the disease tends to run a subacute course and to appear more frequently in the third trimester of pregnancy. We present the case of a 36-year-old woman with large vegetations on the mitral valve due to infective endocarditis detected at the 32nd week of her first pregnancy. The difficulties in selecting the appropriate management strategy, particularly optimal time and mode of delivery, optimal time and type of valve surgery, are emphasized.

Abstract
As increasing numbers of children with congenital heart disorders reach adulthood, the family physician, cardiologist, and obstetrician will increasingly be called upon to give advice regarding the safety of pregnancy. This need has been further highlighted by the recognition that maternal mortality associated with cardiac disease is rising. Unfortunately, this field of practice remains relatively "evidence-sparse" with many management decisions being guided by anecdote and "best guess" common sense. Not surprisingly, this results in many fundamental controversies over the optimal care these patients should receive. This article highlights, through the use of case histories, some of these contentious areas, reflecting the different manifestations of congenital maternal cardiac disease and highlighting the limitations of our knowledge.

Abstract
Cardiac disease complicates approximately 1% to 3% of pregnancies and is responsible for 10% to 15% of maternal mortality. The number of women of childbearing age with congenital disease is increasing as advances in diagnosis and treatment improve survival rates and overall health, allowing successful pregnancy. Pregnant women with severe cardiac disease or women who experience a cardiac event during pregnancy will require admission and stabilization in an adult critical care unit. This group of patients can prove challenging for the obstetrical staff and the critical care staff because they require blending of the knowledge and skills of 2 highly specialized areas of healthcare. The key component to a comprehensive and organized approach to management that ensures the best possible outcome for the woman is a multidisciplinary team that devises a plan on the basis of the most current information, communicates with each other and the patient effectively, and assumes responsibility for implementation of the plan. The purpose of this article is to review management of the woman with cardiac disease throughout pregnancy.

Abstract
PURPOSE OF REVIEW Part I of this review gives an overview of the hemodynamic changes that occur in normal pregnancy, the approach to the pregnant patient with complaints during pregnancy, and the general management of cardiac disease in pregnancy. RECENT FINDINGS The maternal circulatory adaptation to pregnancy consists almost entirely of adaptive changes in the maternal cardiovascular system in response to a primary systemic vasodilatation. Conversely, hemodynamic maladaptation consists of a combination of absence of these changes with signs of sympathetic dominance in the autonomic control of the cardiovascular system. SUMMARY The hemodynamic changes of normal pregnancy per se have profound effects on preexisting cardiac function. Counseling of and care for this subset of patients are challenging for the obstetrician, cardiologist, anesthesiologist and, sometimes, the intensivist to optimize maternal and neonatal survival.

Abstract
PURPOSE OF REVIEW Part II of this review gives an overview of the different maternal cardiac problems during pregnancy and their management, and developments over recent years. RECENT FINDINGS Many studies published over the last 5 years provided new insights on different cardiac diseases in pregnancy. Publications discussed in this part of the review on cardiac disease in pregnancy, for example, provide epidemiological data on heart disease during pregnancy in general, and cardiomyopathy and ischemic heart disease in particular. In addition, we discussed the implications of a history of peripartum cardiomyopathy for a subsequent pregnancy, interventional strategies during pregnancy in women with ischemic heart disease, and the role of echocardiography in the evaluation of cardiac disease in pregnancy. SUMMARY The prevalence of the different causes of heart disease has shifted towards congenital heart disease by the end of the millennium. In developing countries, relatively rare diseases like rheumatic fever are still common, so these diseases are increasingly 'exported' to developed countries. The group of women with congenital heart disease represents most women with heart disease during pregnancy, followed by rheumatic heart disease. With the exception of patients with Eisenmenger's syndrome, pulmonary vascular obstructive disease, and Marfan's syndrome with aortopathy, maternal death during pregnancy is rare in women with heart disease. Although the risk for mortality is low in pregnant women with preexistent cardiac disease, these women are at increased risk for serious morbidity such as heart failure, arrhythmias, and stroke.

Abstract
PURPOSE OF REVIEW This review will summarize the latest publications on the causes, prevention and treatment of maternal collapse during pregnancy and the postpartum period. It will also explore some future trends particularly in the area of education and team working. RECENT FINDINGS Active management of the third stage of labour has been shown to decrease the incidence of postpartum haemorrhage. Inadequate or prolonged resuscitation following major postpartum haemorrhage can lead to myocardial damage. Guidelines that are followed and the use of drills and simulators may increase effective team working and lead to earlier recognition and treatment of maternal collapse. Some cases of amniotic fluid embolism resemble anaphylaxis and should be treated as such. Important evidence-based guidelines on the management of antithrombolytic prophylaxis and the management of pulmonary embolism have recently been published, which should help clinicians clarify their medical care plans. New resuscitation guidelines in the UK will probably mean that all healthcare workers (including obstetricians and midwives) will need appropriate training every year. SUMMARY Understanding the causes of maternal collapse, its early recognition and prompt resuscitation should decrease both maternal and fetal morbidity and mortality. There is increasing evidence that effective preventative measures and improved multidisciplinary team working may have an important impact on maternal and fetal well-being.

Abstract
The incidence of infective endocarditis during pregnancy has been reported to be 0.006%. The maternal mortality rate can reach 33%, with most deaths related to heart failure or an embolic event. The rate of fetal mortality can reach 29%. Heart diseases are the most important nonobstetric causes of maternal death during pregnancy, accounting for 10% of maternal deaths. As many as 3% of women have a form of cardiac disease diagnosed during or in the period preceding pregnancy, with 70 to 80% of the cardiac conditions having congenital causes.

Abstract
Ebstein's anomaly is a common congenital abnormality in the Wolff-Parkinson white syndrome (WPW). The term WPW is applied to patients with both preexcitation on ECG and paroxysmal tachycardias. In this case review, we describe a female with a history of intermittent palpitations who presented in the postpartum period with WPW. Subsequent testing revealed an underlying Ebstein's anomaly. In the United States, heart disease is responsible for 10% of maternal deaths. Although pregnancy is well known to exacerbate symptoms in patients with WPW, postpartum exacerbation has not been clearly described. This unusual case suggests that monitoring beyond the peurperium would be advisable in patients at risk to develop malignant tachyarrhythmias.

Abstract
Cardiac diseases are present in 0.5-4% of pregnancies, and they remain a frequent cause of death during pregnancy. Pregnancy per se imposes significant hemodynamic changes, placing a major burden on the cardiovascular system. The early recognition and close follow-up of patients with cardiac diseases will improve maternal tolerance to the cardiovascular burden imposed by pregnancy, promote fetal growth and neonatal survival. Rheumatic heart disease remains the most frequent heart disease in the pregnant population with pulmonary edema as the most frequent complication. Atrial septal defect is the most frequent congenital heart disease in the adult population, whereas tetralogy of Fallot is the most common cyanotic congenital heart disease. An improvement in modern techniques of monitoring, a better understanding of the pathophysiology of cardiac disease, as well as multidisciplinary care has led to a substantial improvement in outcome of the pregnant cardiac patient. Management should be initiated before conception as it will provide optimal clinical conditions and sufficient information on the underlying pathophysiology.

Abstract
Congenital heart disease in pregnancy is increasingly common because of the advances in surgery and medical therapy which have taken place over the last 30 years, which means that more affected women are surviving into the reproductive age. Antenatal counselling needs to be tailored to the specific lesion, with pulmonary hypertension and cyanotic disease presenting a risk of maternal mortality of up to 50%. The use of anticoagulants in women with artificial valves presents a particular challenge, heparin being safer for the baby and warfarin for the mother. Peripartum cardiomyopathy and Marfan's syndrome may be less dangerous than once thought. The risk of congenital heart disease in the fetus is increased, from twice to 20-fold, depending on the nature of the mother's lesion. Care throughout pregnancy and in the puerperium should be multidisciplinary and include cardiologists, obstetricians and midwives with experience of such cases, preferably in a tertiary centre.
