Abstract
A 32-year-old Caucasian woman presented with shortness of breath four weeks postpartum. She was known to suffer from systemic lupus erythematosus with cutaneous, joint and minor renal involvement. During pregnancy, the patient had developed nephrotic syndrome for which she was managed with prophylactic anticoagulation and corticosteroid therapy. A leg deep vein thrombosis had arisen following caesarean section following antepartum haemorrhage. Examination revealed a heart murmur, and pulmonary signs. Computed tomography pulmonary angiogram showed cardiomegaly and bilateral pleural effusions but no pulmonary embolus. Echocardiogram demonstrated dilated cardiomyopathy. An initial diagnosis of peripartum cardiomyopathy was considered, with lupus myocarditis and coronary in situ thrombosis among the differential diagnoses.

Abstract
Peripartum cardiomyopathy (PPCM) is a rare and life-threatening disease that affects young women in the last month of pregnancy or within 5 months of delivery. It is a form of dilated cardiomyopathy with left-sided systolic dysfunction. The incidence rate in the Western world is estimated to be 1:3000. Symptoms of PPCM vary greatly and may be obscured by common physiological aspects of pregnancy. Therefore, the incidence rate might be higher. Echocardiography or MRI can confirm or rule out PPCM. Unfortunately, there is no specific risk factor profile available. The clinical course varies from complete recovery to deterioration of cardiac function. Patients with PPCM, especially those whose ventricular function has not returned to normal, are advised against further pregnancy. Recently, more disease-specific therapeutic strategies have been developed with promising results for prolactin blockade by bromocriptine. Increasing awareness for PPCM among general practitioners, gynaecologists and cardiologists may help to diagnose patients efficiently in order to start adequate treatment. A national registry is warranted to identify risk factor profiles and to optimise treatment strategies.

Abstract
Although multiple mechanisms have been postulated, peripartum cardiomyopathy (PPCM) continues to be a cardiomyopathy of unknown cause. Multiple risk factors exist and the clinical presentation does not allow differentiation among potential causes. Although specific diagnostic criteria exist, PPCM remains a diagnosis of exclusion. Treatment modalities are dictated by the clinical state of the patient, and prognosis is dependent on recovery of function. Randomized controlled trials of novel therapies, such as bromocriptine, are needed to establish better treatment regimens to decrease morbidity and mortality. The creation of an international registry will be an important step to better define and treat PPCM. This article discusses the pathogenesis, risk factors, diagnosis, management, and prognosis of this condition.

Abstract
Peripartum cardiomyopathy is a devastating condition in which women without a previously identified heart condition experience heart failure in the ninth month of pregnancy or in the first 5 months after delivery of a baby. Online support groups are virtual communities for people affected by the same social or health issue. No literature exists on the benefits of women involved in an online support group for peripartum cardiomyopathy. The purpose of this descriptive study was to determine the benefits of participation in the online support group for peripartum cardiomyopathy based on a survey of active members of the group. All contacts between researchers and respondents were through e-mail. A survey of open-ended and Likert-type questions was used. Twelve women, aged 19 to 34 years, participated; all had a diagnosis of peripartum cardiomyopathy. This online support group is a vital resource for women with peripartum cardiomyopathy. Benefits to participation in the online support group included getting and sharing information, exchanging stories, being understood by other women, and gaining hope. Nurse practice implications include referring patients to reputable Web sites and support groups and serving as a professional facilitator in an online group.

Abstract
BACKGROUND Peripartum cardiomyopathy (PPCM or PCMO) is a rare disease of unknown etiology, characterised by an acute onset of heart failure in women in the late stage of pregnancy or in the early months postpartum. OBJECTIVES To assess the effectiveness and safety of any intervention for the care of women and/or their babies with a diagnosis of peripartum cardiomyopathy. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (27 July 2010) and the reference lists of identified studies. SELECTION CRITERIA Randomised and quasi-randomised controlled trials of any intervention for treating peripartum cardiomyopathy. Such interventions include: drugs; cardiac monitoring and treatment; haemodynamic monitoring and treatments; supportive therapies and heart transplant. DATA COLLECTION AND ANALYSIS Two authors independently assessed the studies for inclusion, assessed risk of bias and carried out data extraction. Data entry was checked. MAIN RESULTS We identified and included one pilot study, involving 20 women, undertaken in South Africa. Women were diagnosed postnatally and included in the study within 24 hours of diagnosis. AUTHORS' CONCLUSIONS There are insufficient data to draw any firm conclusions. Treatment with bromocriptine appears promising, although women would be unable to breastfeed due to suppression of lactation.

Abstract
Peripartum cardiomyopathy (PPCM) is a dilated cardiomyopathy defined as systolic cardiac heart failure in the last month of pregnancy or within five months of delivery. PPCM, which affects thousands of women each year in the US, was first described in the 1800s, yet its etiology is still unclear. Its diagnosis is often delayed because its symptoms closely resemble those within the normal spectrum of pregnancy and the postpartum period. When PPCM is misdiagnosed or its diagnosis is delayed, the consequences for patients are deadly: The disorder carries a high mortality rate.

Abstract
Here we report an unusual development of peripartum cardiomyopathy (PPCM) in a parturient woman with preeclampsia. A 36-year-old nulliparous parturient woman underwent elective cesarean section for delivery of twins under spinal anesthesia. Both preoperative workup and past history were unremarkable except for proteinuria and hypertension for 1 week. Approximately 4 hours after cesarean section, progressive orthopnea developed. Chest plain film showed acute pulmonary edema, bilateral pulmonary infiltration with interstitial patches, and cardiomegaly. Postpartum cardiomyopathy was diagnosed afterward by echocardiography. This showed general hypokinesia and severe dysfunction of the left ventricle with ejection fraction of 15-20%. She was admitted to the intensive care unit for further management. Fortunately, the patient recovered after treatment and was discharged 15 days later. This case illustrates that we should bear in mind the possibility of PPCM if orthopnea develops while delivery is approaching in a parturient with preeclampsia. Echocardiography is helpful for early diagnosis of PPCM.

Abstract
Peripartum cardiomyopathy (PPCM) is a rare but potentially lethal complication of pregnancy occurring in approximately 1 : 3,000 live births in the United States although some series report a much higher incidence. African-American women are particularly at risk. Diagnosis requires symptoms of heart failure in the last month of pregnancy or within five months of delivery in the absence of recognized cardiac disease prior to pregnancy as well as objective evidence of left ventricular systolic dysfunction. This paper provides an updated, comprehensive review of PPCM, including emerging insights into the etiology of this disorder as well as current treatment options.

Abstract
BACKGROUND Peripartum cardiomyopathy (PPCM) is a rare cardiomyopathy with a high risk of mortality. The present study assessed clinical outcome and mortality over a 2-year period in an African cohort of 80 PPCM patients. METHODS A prospective study over a 2-year period at a tertiary center, where 80 consecutive women presenting with PPCM were enrolled on first diagnosis. Patients obtained standard heart failure therapy. Detailed assessments included echocardiography, NYHA functional class, left ventricular ejection fraction (LVEF), mortality and serum levels for hemoglobin, CRP, IL-6, TNF-alpha, Fas/Apo-1, and T-cell count at each 6-month intervals for 24 months. RESULTS Baseline mean age was 30 ± 7 years; 38% were primigravidas and 34% were co-infected with HIV. NYHA functional class III-IV was present in 89% patients with a mean LVEF of 30 ± 9%. Four patients were lost to follow-up, 9 moved to remote areas, 7 were excluded due to subsequent pregnancy. The 2-year mortality rate was 28%. Eight of 80 (10%) died by 6 months. Mean LVEF of surviving patients was: 44 ± 11% at 6-months, 46 ± 13% at 12-months and 50 ± 14% at 24-months follow-up. Of the 69 patients still enrolled at 6 months 14 (20%) died over the remaining 18-month period, despite functional recovery. No statistically significant difference in LVEF and mortality was observed between PPCM patients with or without HIV co-infection. CONCLUSION The novel finding of this study is the continuous high mortality of PPCM patients occurring beyond 6 months independent of HIV infection and subsequent pregnancy. This finding strongly encourages the need for long-term clinical follow-up and management of women with PPCM.

Abstract
The aetiology of peripartum cardiomyopathy (PPCM) is still largely unknown. Recent evidence suggests that the breakdown products from prolactin can induce cardiomyopathy. Prolactin secretion can be reduced with bromocriptine which had beneficial effects in a small study. We present a case of a patient with PPCM who received cabergoline, a strong and long lasting antagonist of prolactin secretion. Following treatment, her prolactin levels dropped swiftly. N-terminal pro-BNP levels, which had remained high up to that point, dropped within 1 day (7006 to 4408 pg/mL). Echocardiographic left ventricular ejection fraction recovered from 26% on day 4 postpartum to 32% and later 47% on days 2 and 5 after cabergoline treatment. To our knowledge, this is the first description of a case of PPCM in which cabergoline was administered.

Abstract
Peripartum cardiomyopathy (PPCM) is a serious, potentially life-threatening heart disease of unknown etiology in previously healthy women that develops between the last month of pregnancy and 5–6 months after delivery. PPCM is a distinct clinical entity in which echocardiography demonstrates the features of an idiopathic dilated cardiomyopathy with a high morbidity and mortality, but in addition, patients suffering with PPCM have a chance of reaching full recovery. A variety of potential risk factors related to PPCM have been suggested over the last decades, which may help to identify women at risk in the future. Recent advances in understanding the pathophysiology of PPCM assign a key role to unbalanced oxidative stress and the generation of a cardiotoxic prolactin subfragment. In this regard, pharmacological blockade of prolactin holds the promise of novel, more disease-specific therapy options. The present article provides an overview on the clinical appearance and management, risk factors and potential pathophysiological mechanisms of PPCM.

Abstract
INTRODUCTION Peripartum cardiomyopathy (PPCM) is a rare and life-threatening disease of unknown aetiology. The primary objective of this review was to analysed aetiopathogeneses, clinical presentation and diagnosis, as well as pharmacological, perioperative and intensive care management and prognosis of this pathology. METHODS We undertook a systematic review of the literature using Medline, Google Scholar and PubMed searches. RESULTS Unlike other parts of the world in which cardiomyopathy are rare, dilated cardiomyopathy is a major cause of heart failure throughout Africa. Its aetiopathogenesis is still poorly understood, but recent evidence supports inflammation, viral infection and autoimmunity as the leading causative hypotheses. This diagnosis should be limited to previously healthy women who present with congestive heart failure (CHF) and decreased left ventricular systolic function in the last month of pregnancy or within 5 months after delivery. Recently, introduction of echocardiography has made diagnosis of PPCM easier and more accurate. Conventional treatment consists of diuretics, vasodilators, and sometimes digoxin and anticoagulants, usually in combination. Patients who fail to recover may require inotropic therapy. In resistant cases, newer therapeutic modalities such as immunomodulation, immunoglobulin and immunosuppression may be considered. Prognosis is highly related to reversal of ventricular dysfunction. Compared to historically higher mortality rates, recent reports describe better outcome, probably because of advances in medical care. Based on current information, future pregnancy is usually not recommended in patients who fail to recover normal heart function. CONCLUSION PPCM is a rare but serious form of cardiac failure affecting women in the last months of pregnancy or early puerperium. Its aetiopathogenesis is still poorly understood. Introduction of echocardiography has made diagnosis of PPCM easier and more accurate. Prognosis is highly related to reversal of ventricular dysfunction.

Abstract
Two women, aged 27, presented with different symptoms shortly after giving birth to their first child. Peripartum cardiomyopathy (PPCM) was diagnosed. PPCM is a rare form of cardiac failure occurring late in pregnancy or in the postpartum period. Many women experience dyspnoea, fatigue, and pedal oedema in the last month of pregnancy or postpartum, symptoms which are identical to early congestive heart failure. Therefore, the diagnosis of PPCM requires vigilance. A high mortality rate and overall poor clinical outcome has been reported in a high percentage of these patients. Subsequent pregnancies remain controversial. (Neth Heart J 2008;16:415-8.).

Abstract
OBJECTIVE The objective of the study was to assess the prognostic value of ejection fraction (EF) at index and subsequent pregnancy on long-term outcome in patients with peripartum cardiomyopathy (PPCM). STUDY DESIGN Seventy PPCM patients met inclusion criteria. Patients had echocardiography evaluations at the index pregnancy, at interval follow-up (F/U) or at the beginning of a subsequent pregnancy and the last F/U study available. Outcome data were echocardiographic parameters and the subsequent need for cardiac transplant. RESULTS Patients were categorized on the basis of their initial EF into EF of 25% or less and EF greater than 25% and stratified on the basis of their pregnancy into the following groups: group 1 (n = 33), no subsequent pregnancy; group 2 (n = 16), subsequent pregnancy with early termination; and group 3 (n = 21), successful subsequent pregnancy. F/U from index pregnancy to final F/U was 3.4+/-1.9 (range, 1-6 years). Groups 1 and 2 had persistent left ventricular dysfunction at all echocardiographic evaluations. In group 3, despite a mean EF greater than 40% at a subsequent pregnancy, 29% had worsening cardiac symptoms. Among 28 patients with EF of 25% or less, 16 (57%) had end-stage cardiac disease. One had a transplant and 15 were on a transplant list. All 16 had a baseline EF 25% or less at index pregnancy: 4 had improved (EF greater than 40%) at interval F/U and 3 at last F/U available. CONCLUSION Women with a history of PPCM had a higher rate of progression of symptoms of heart failure in a subsequent pregnancy. A baseline left ventricular EF 25% or less at index pregnancy is associated with a higher rate of cardiac transplant.

Abstract
Peripartum cardiomyopathy (PPCM) is a rare but serious form of cardiac failure affecting women in the last months of pregnancy or early puerperium. Clinical presentation of PPCM is similar to that of systolic heart failure from any cause, and it can sometimes be complicated by a high incidence of thromboembolism. Prior to the availability of echocardiography, diagnosis was based only on clinical findings. Recently, inclusion of echocardiography has made diagnosis of PPCM easier and more accurate. Its etiopathogenesis is still poorly understood, but recent evidence supports inflammation, viral infection and autoimmunity as the leading causative hypotheses. Prompt recognition with institution of intensive treatment by a multidisciplinary team is a prerequisite for improved outcome. Conventional treatment consists of diuretics, beta blockers, vasodilators, and sometimes digoxin and anticoagulants, usually in combination. In resistant cases, newer therapeutic modalities such as immunomodulation, immunoglobulin and immunosuppression may be considered. Cardiac transplantation may be necessary in patients not responding to conventional and newer therapeutic strategies. The role of the anesthesiologist is important in perioperative and intensive care management. Prognosis is highly related to reversal of ventricular dysfunction. Compared to historically higher mortality rates, recent reports describe better outcome, probably because of advances in medical care. Based on current information, future pregnancy is usually not recommended in patients who fail to recover heart function. This article aims to provide a comprehensive updated review of PPCM covering etiopathogeneses, clinical presentation and diagnosis, as well as pharmacological, perioperative and intensive care management and prognosis, while stressing areas that require further research.

Abstract
Cardiac disorders complicate less than 1% of all pregnancies. Physiologic changes in pregnancy may mimic heart disease. In order to differentiate these adaptations from pathologic conditions, an in-depth knowledge of cardiovascular physiology is mandatory. A comprehensive history, physical examination, electrocardiogram, chest radiograph, and echocardiogram are sufficient in most cases to confirm the diagnosis. Care of women with cardiac disease begins with preconception counseling. Severe lesions should be taken care of prior to contemplating pregnancy. Management principles for pregnant women are similar to those for the non-pregnant state. A team approach comprised of a maternal fetal medicine specialist, cardiologist, neonatologist, and anesthesiologist is essential to assure optimal outcome for both the mother and the fetus. Although fetal heart disease complicates only a small percentage of pregnancies, congenital heart disease causes more neonatal morbidity and mortality than any other congenital malformation. Unfortunately, screening approaches for fetal heart disease continue to miss a large percentage of cases. This weakness in fetal screening has important clinical implications, because the prenatal detection and diagnosis of congenital heart disease may improve the outcome for many of these fetal patients. In fact, simply the detection of major heart disease prenatally can improve neonatal outcome by avoiding discharge to home of neonates with ductal-dependent congenital heart disease. Fortunately, recent advances in screening techniques, an increased ability to change the prenatal natural history of many forms of fetal heart disease, and an increasing recognition of the importance of a multidisciplinary, team approach to the management of pregnancies complicated with fetal heart disease, together promise to improve the outcome of the fetus with congenital heart disease.

Abstract
An 18-year-old pregnant woman had cardiac failure and severe pulmonary edema developed immediately after the delivery of her baby. The patient's respiratory distress was severe and her oxygen saturation was under 50%, despite full mechanical ventilatory support. Echocardiogram revealed an ejection fraction of 18%, and she was diagnosed with peripartum cardiomyopathy. Her vital signs were unstable when she received conventional treatment for acute heart failure. Extracorporeal membrane oxygenation was applied 3 hours after the patient was transferred to the emergency department. The patient was weaned from extracorporeal membrane oxygenation 28 hours afterward, and she was extubated 2 days after extracorporeal membrane oxygenation. The patient was discharged 12 days after admission.

Abstract
Peripartum cardiomyopathy (PPCM) is a rare disorder of dilated cardiomyopathy and left ventricular dysfunction occurring in the last month of pregnancy or within 5 months postpartum. Outcome of PPCM is highly variable, comprising clinical improvement and rapid deterioration unresponsive to medical treatment requiring heart transplantation or even death. In this study, we report the clinicopathologic findings of 10 patients with PPCM who were retrospectively identified in our cardiomyopathy registry. During a follow-up of 69+/-27 months, no patient died or required orthotopic heart transplantation. Left ventricular ejection fraction was 38+/-7% at the time of diagnosis and 53+/-7% during follow-up. While all patients had sinus rhythm at the time of diagnosis, three patients presented with left bundle branch block. We found no evidence of viral infection in endomyocardial biopsy samples of seven patients by PCR. Histopathologic findings revealed the presence borderline myocarditis in two of seven patients (29%). Circulating autoantibodies to cardiac tissue of any kind were observed in all patients. In conclusion, in our retrospective observational study, no patient diagnosed with PPCM died or received orthotopic heart transplantation. Improvement of left ventricular ejection fraction was present in eight patients (80%), while LV dysfunction persisted in four patients. Our findings support the hypothesis of an underlying autoimmune pathomechanism in this rare disease.

Abstract
Peripartum cardiomyopathy (PPCM) is a rare disorder in which left ventricular dysfunction and symptoms of heart failure occur in the peripartum period in previously healthy women. Incidence of PPCM ranges from 1 in 1300 to 1 in 15,000 pregnancies. The etiology of PPCM is unknown, but viral, autoimmune, and idiopathic causes may contribute. The diagnostic criteria are onset of heart failure in the last month of pregnancy or in first 5 months postpartum, absence of determinable cause for cardiac failure, and absence of a demonstrable heart disease before the last month of pregnancy. Risk factors for PPCM include advanced maternal age, multiparity, African race, twinning, gestational hypertension, and long-term tocolysis. The clinical presentation of patients with PPCM is similar to that of patients with dilated cardiomyopathy. Early diagnosis and initiation of treatment are essential to optimize pregnancy outcome. Treatment is similar to medical therapy for other forms of dilated cardiomyopathy. About half the patients of PPCM recover without complications. The prognosis is poor in patients with persistent cardiomyopathy. Persistence of disease after 6 months indicates irreversible cardiomyopathy and portends worse survival.

Abstract
Peripartum cardiomyopathy is a rare and under recognized form of dilated cardiomyopathy, defined as a heart failure in the last month of pregnancy or in the first five months post-partum with absence of determinable cause for cardiac failure and absence of demonstrable heart disease. The incidence of peripartum cardiomyopathy ranges from 1 in 1300 to 1 in 15,000 pregnancy. Advanced maternal age, multiparity, twin births, preeclampsia and black race are known risk factors. The etiology of peripartum cardiomyopathy remains unknown but viral, autoimmune or idiopathic myocarditis are highly suggested. The clinical presentation on patients with peripartum cardiomyopathy is similar to that of patients with systolic heart failure. The treatment is based on drugs for sympyomatic control. Studies in graeter populations are need to determine the role of immunosupressive treatment. About half patients of peripartum cardiomyopathy recover. The left ventricular ejection fraction and the left ventricular end-diastolic diameter are statistically significant prognostic factors. The risk of developing peripartum cardiomyopathy in subsequent pregnancies remains high. The place of dobutamine stress test in counseling the patients who desire pregnancy must be more studied.

Abstract
Peripartum cardiomyopathy is a rare and potentially lethal cardiac complication of pregnancy occurring in the final month of pregnancy through the first 5 months after birth. It is characterized by the development of congestive heart failure and left ventricular systolic dysfunction, in previously healthy women with no other identifiable cause for heart failure. The etiology of peripartum cardiomyopathy is not well understood. Potential causal mechanisms include infection, autoimmune disease, and abnormal response to the hemodynamic stresses of pregnancy. There is significant risk of reoccurrence in subsequent pregnancies. The purpose of this article is to review the pathophysiology, diagnosis, management, prognosis, and nursing implications of peripartum cardiomyopathy.

Abstract
BACKGROUND Prior studies have shown both high morbidity and mortality for patients with peripartum cardiomyopathy (PPCM). These studies were small and predated current advances in heart failure treatment. We sought to determine the outcomes of women with PPCM in the contemporary era and to determine predictors of poor outcome. METHODS Patients with PPCM from 1990 to 2003 were identified retrospectively through screening of heart failure clinics and echocardiography records. Their records were reviewed, and current clinical status was determined. RESULTS Fifty-five patients were identified with an average follow-up of 43 months. Their mean initial ejection fraction (EF) was 20%. Compared with their initial EF, 62% of patients improved, 25% were unchanged, and 4% declined. No patients died, and 10% eventually required transplant. At 2 months after diagnosis, 75% of those who eventually recovered had an EF >45%. Factors associated with lack of recovery at initial assessment were a left ventricular (LV) end-diastolic dimension >5.6 cm, the presence of LV thrombus, and African-American race. Recovery of LV function was not predicted by the initial EF. Among patients who recovered, the withdrawal of heart failure medications was not associated with decompensation over a follow-up of 29 months. CONCLUSIONS The morbidity related to PPCM is less than previously reported. Initial LV end-diastolic dimension and EF at 2 months predict long-term outcomes. The discontinuation of heart failure medications after recovery did not lead to decompensation.

Abstract
Reports from case series have estimated the incidence of peripartum cardiomyopathy (PC) at 1 case/1,485 live births to 1 case/15,000 live births and probable mortality rates of 7% to 60%. The objective of this study was to produce the first population-based study of the incidence, mortality, and risk factors for PC. The National Hospital Discharge Survey was used. Discharge information was available for 3.6 million patient discharges from 1990 to 2002. There were an estimated 16,296 cases of PC from 1990 to 2002. During this period, there were 51,966,560 live births in the United States. Thus, the incidence of PC was 1 case/3,189 live births. There was a trend toward an increase in PC incidence during the study period, with an estimate for the years 2000 to 2002 of 1 case/2,289 live births. The in-hospital mortality rate was 1.36% (95% confidence interval 0% to 10.2%). The total mortality rate was 2.05% (95% confidence interval 0.29% to 10.8%). Patients with PC were older (mean age 29.7 vs 26.9 years), were more likely to be black (32.2% vs 15.7%), and had a higher incidence of pregnancy associated hypertensive disorders (22.5% vs 5.87%) compared with national data. In conclusion, the incidence of PC is relatively uncommon, occurring at an average frequency of 1 case/3,189 live births from 1990 to 2002. The estimated mortality of 1.36% to 2.05% (95% confidence interval 0.29% to 10.8%) is less than previously reported from most case series.

Abstract
Peripartum cardiomyopathy (PPCM) is a rare cardiac disorder associated with high rates of mortality that occurs during the peripartum period. PPCM is recognized as a distinct entity, separate from preexisting cardiomyopathies that are worsened by the stressors of pregnancy. To date, its etiology is unknown, although several theories are under investigation in an effort to provide more information regarding available treatment options. A multidisciplinary review of PPCM held by the National Heart, Lung, and Blood Institute, in conjunction with the Office of Rare Disease of the National Institutes of Health, in April 1997 reviewed the current knowledge and developed recommendations for areas of further research and education about PPCM. Since then, there have been some promising research testing hypotheses regarding the etiology of PPCM and advancements in possible treatment options. However, despite these efforts, knowledge and treatment recommendations about PPCM are still generally unchanged, whereas mortality rates remain high. This article attempts to provide an updated, comprehensive review about PPCM and draw attention to areas in need of further research.

Abstract
OBJECTIVE To determine the incidence and prognosis of peripartum cardiomyopathy (PPCM) in rural Haiti. PATIENTS AND METHODS Prospectively identified patients with PPCM treated at the Hospital Albert Schweitzer (HAS), Deschapelles, Haiti, were included in this study. Patients who presented to HAS from February 1, 2000, to January 31, 2005, were identified through a search of the HAS PPCM Registry. Clinical and serial echocardiographic data were collected on these patients. RESULTS The 5-year experience confirms the high incidence of PPCM in this area, approximately 1 case per 300 live births, which is severalfold the estimated incidence in the United States (estimated 1 case per 3000 to 4000 live births). In this population, the ratio of PPCM deaths for the 5-year period was 47.1 per 100,000 births compared with the US ratio of 0.62 per 100,000 births. The mortality rate was 15.3% (15 deaths of 98 patients), and the mean follow-up was 2.2 years (range, 1 month to 5 years). Five years after the initiation of the HAS PPCM Registry search, 26 (28%) of 92 patients with PPCM observed for at least 6 months had regained normal left ventricular function. The difference in left ventricular echocardiographic features at diagnosis between deceased patients and survivors was not statistically significant: mean end-diastolic dimension (6.2 vs 5.8 cm; P=.08), ejection fraction (22% vs 25%; P=.12), and fractional shortening (16% vs 15%; P=.46). Left ventricular echocardiographic features at diagnosis were unable to predict individually who would eventually recover, although a statistically significant difference occurred at diagnosis between the recovered group and nonrecovered group for mean ejection fraction (28% vs 23%; P<.001) and fractional shortening (17% vs 14%; P=.004). CONCLUSION Peripartum cardiomyopathy occurs significantly more commonly in rural Haiti on a per capita basis than in the United States. Patients with PPCM have a higher mortality rate and a poorer return of normal ventricular function.

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
BACKGROUND The impact and clinical relevance of pregnancy-related heart failure (HF) on humoral immunity are not known. Heart failure is often characterized by immunoglobulins (Ig) that differ in subclass profile with etiology. Subclass immunoglobulins differ in the biologic information they confer in disease. Therefore, given that progressive gestation is associated with immunologic incompetence, we sought to study the relative impact of pregnancy-related onset of HF on humoral immunity. METHODS Immunoglobulins (class G and subclasses G1, G2, G3) against cardiac myosin were evaluated in 47 patients with peripartum cardiomyopathy (PPCM) from different global regions: South Africa (n = 15), Mozambique (n = 9), and Haiti (n = 23) and compared with healthy mothers and patients with idiopathic dilated cardiomyopathy (DCM). C-reactive protein, tumor necrosis factor-alpha, and Fas-Apo-1 were also studied in PPCMs. RESULTS All PPCM groups were similar in Ig profiles. The immunoglobulins, frequencies and reactivities, were markedly and nonselectively raised in PPCM patients compared with DCM. Immunoglobulin frequencies in PPCMs, Haiti: G1 58%, G2 66%, G3 54%; Mozambique: G1 77%, G2 66%, G3 66%; and South Africa: G1 47%, G2 53%, G3 53%, were higher compared with DCMs from South Africa (n = 24): G1 8%, G2 8%, G3 21%, or the United Kingdom (n = 68): G1 10%, G2 8.8%, G3 22% (P < .0001). Hence, unlike the selective up-regulation of immunoglobulins of the G3 subclass (IgG3s) in DCM, class G and all subclass immunoglobulins were raised in PPCM. Of the serological variables, IgG3s (immunoglobulins with proinflammatory characteristics) discriminated NYHA functional status at diagnosis. IgG3-positive patients were in a higher NYHA class at initial presentation (P < .05). CONCLUSIONS Immunoglobulin subclass profiles in patients with HF differ with etiology. Unlike DCM, the impact of pregnancy-related HF on humoral immunity is not subclass-restricted. However, raised levels of IgG3s may be of prognostic value in clinical PPCM.

Abstract
OBJECTIVES We sought to determine the prognostic use of inotropic contractile reserve on risk stratification and prognostication of women with peripartum cardiomyopathy. BACKGROUND Peripartum cardiomyopathy is a rare disorder effecting women in their prime years of life. There appears to be an initial high-risk period with 25% to 50% of women dying within the first 3 months postpartum. Early risk stratification and prognostication are, thus, crucial. However, only limited data are available. METHODS In all, 7 women (mean age 31.8 years) with peripartum cardiomyopathy and severe left ventricular (LV) dysfunction (mean LV ejection fraction [LVEF] 25.3 +/- 9.5%) were studied. Of these, 6 underwent dobutamine stress echocardiography at baseline and a follow-up resting echocardiogram at a mean of 4.7 +/- 0.9 months after initial presentation. Resting and peak inotropic contractile reserve, and follow-up LVEF, were computed. RESULTS The mean LVEF improved significantly from baseline (25.3 +/- 9.5%) to maximal inotropic contractile reserve (53.8 +/- 12.6%) (P = .0004) and at follow-up (53.0 +/- 16.4%) (P = .006). Importantly, LVEF at maximal inotropic contractile reserve and at follow-up (5.6 months) did not differ significantly (P = .5). The mean LVEF at maximal inotropic contractile reserve correlated well with the follow-up (LVEF R = 0.79). However, the baseline LVEF did not correlate with follow-up LVEF (P = not significant). CONCLUSIONS In patients presenting with peripartum cardiomyopathy, inotropic contractile reserve during dobutamine stress echocardiography accurately correlates with subsequent recovery of LV function and confers a benign prognosis.

Abstract
Peripartum cardiomyopathy is a rare condition of unclear etiology that accounts for an important percentage of pregnancy-related deaths. Deaths from peripartum cardiomyopathy can be attributed to profound left ventricular failure, thromboembolic events, or arrhythmia. Prompt recognition of the condition, initiation of appropriate medical management, collaboration with perinatology for delivery management, referral to cardiac transplant centers when necessary, and counseling regarding future pregnancies is required for a successful outcome. Patients should be diagnosed by clinical evaluation and echocardiography. After establishing left ventricular dysfunction, a standard heart failure medical regimen should be instituted. Hospitalization should be considered for patients with class III or greater symptoms, or for those patients not responding to outpatient management. If the diagnosis is made in the antepartum period, delivery should be strongly considered. Endomyocardial biopsy has low yield in this situation and should not be considered standard care, especially because controversy exists over the effectiveness of immunosuppressive therapy for myocarditis. Selenium, pentoxifylline, and immune globulin have all been shown to have a beneficial effect in small series of patients. The addition of these agents to standard therapy, however, should be considered on a case-by-case basis. Anticoagulation should be considered in patients with ejection fractions less than 35%. Transplantation results in survival comparable to women with idiopathic-dilated cardiomyopathy, and should be pursued in the appropriate setting. Future pregnancies should be discouraged, even if the left ventricular function recovers. Significant improvement in ventricular function can be expected in up to 50% of patients.

Abstract
The diagnosis of peripartum cardiomyopathy should be considered whenever women present with heart failure during the peripartum period. This cardiomyopathy is distinguished by rapid onset, occurrence in the peripartum period, and significant improvement in up to 50% of affected women. The cause and pathogenesis of this dilated cardiomyopathy remain unknown. Treatment is similar to medical therapy for other forms of dilated cardiomyopathy. Worsening of heart failure may require management in the ICU with support by vasodilators, inotropes, and ventricular assist devices. Patients with severe ventricular dysfunction are less likely to survive and recover normal cardiac function. Subsequent pregnancies may provoke a recurrence, even in patients who apparently recover.

Abstract
Heart disease is a leading cause of maternal death. The aim of this study is to review the most common causes of cardiac disease, highlight factors that should be recognized by the clinician, and address recent advances in the anaesthetic management of these patients. Incipient cardiac disease, including peripartum cardiomyopathy, myocardial infarction and aortic dissection, accounts for approximately one in six maternal deaths. The keys to successful diagnosis and management of incipient disease are: a high index of suspicion, particularly in women with known risk factors for cardiovascular disease; a low threshold for radiological investigations; early cardiology input; and invasive monitoring during labour and delivery. Echocardiography is a safe, non-invasive test, under-used in pregnancy. Management of pregnant women with pre-existing cardiac problems should be undertaken by multidisciplinary teams in tertiary centres. In women with pre-existing cardiac disease wishing to proceed to term, cardiac status must be optimized preoperatively and planned elective delivery is preferable. Vaginal delivery is preferable, and with careful incremental regional anaesthesia is safe in most women with cardiac disease. The presence of adequate systems for early detection, appropriate referral to specialist centres, and timely delivery with multidisciplinary support can minimize the serious consequences of poorly controlled heart disease in pregnancy.

Abstract
BACKGROUND Lymphocytic myocarditis presents as a primary disorder or in association with a systemic disease. Whether primary and secondary myocarditis have the same prognosis is unknown. METHODS Patients (n = 171) referred to the Johns Hopkins Cardiomyopathy service from 1984 to 1998 with newly diagnosed cardiomyopathy were observed for an average of 5.9 years after an original diagnosis of biopsy-proven myocarditis or until reaching the end point of death. Giant-cell myocarditis was excluded from this study. Myocarditis was classified as secondary when a systemic disease was present at the time of presentation; otherwise, myocarditis was classified as primary. Survival rates among patients with primary and secondary myocarditis were compared with Kaplan-Meier analysis and Cox proportional hazard models incorporating clinical variables, including baseline hemodynamics and treatment with immunosuppressive therapy. RESULTS The mortality rate associated with secondary myocarditis varied substantially depending on the underlying systemic disorder. Peripartum myocarditis, when compared with idiopathic myocarditis, had a reduced mortality rate (relative hazard, 0.23 [0.06-0.98]; P <.05), which was attenuated after controlling for confounding variables (relative hazard, 0.62 [0.13-2.98]; P =.55). In contrast, human immunodeficiency virus myocarditis had a particularly poor prognosis (relative hazard, 6.70 [3.51-12.79]; P <.05), even after controlling for confounding variables. Myocarditis associated with systemic inflammatory disorders showed a trend toward increased mortality rate (relative hazard, 2.46 [0.65-9.38]; P =.19). For both primary and secondary myocarditis, advanced age and pulmonary hypertension were important clinical predictors of death. CONCLUSIONS The prognosis of patients with secondary myocarditis, when compared with patients with idiopathic myocarditis, seems most affected by the primary disease process.

Abstract
The anesthetic management of labor and delivery in patients with peripartum cardiomyopathy is not well defined. Using continuous spinal anesthesia in such a rare clinical situation has not been previously reported. A patient with recurrent peripartum cardiomyopathy presented in congestive heart failure for emergent cesarean section. Continuous spinal anesthesia was successfully employed as the anesthetic technique for the procedure. In addition, it also markedly reduced the patient's symptoms. Continuous spinal anesthesia is a reliable, rapidly titratable technique, which provides excellent analgesia with minimal undesirable hemodynamic changes for patients with peripartum cardiomyopathy undergoing cesarean delivery.

Abstract
INTRODUCTION The anesthetic management of labor and delivery in patients with peripartum cardiomyopathy is not well defined. Using continuous spinal anesthesia with bupivacaine or combined spinal epidural anesthesia with ropivacaine in such rare clinical situations has not been previously reported. CASE REPORT We present two cases in which parturients with the diagnosis of peripartum cardiomyopathy presented in congestive heart failure for emergent Cesarean section. Continuous spinal anesthesia and combined spinal-epidural anesthesia were successfully employed as the anesthetic techniques for the procedures. Both patients remained hemodynamically stable during surgery and were discharged home on postoperative days 5 and 4 respectively.

Abstract
The etiology and mechanisms of pathogenesis of human peripartum cardiomyopathy (PPCM) remain unknown. The incidence and prevalence of this disease is rare in some parts of the world and more common in others. The purpose of this review is to summarize our current knowledge of the factors that have been entertained which may contribute to the pathogenesis of PPCM with special emphasis on more recent data from our laboratory that provide support to the view that this disease is an autoimmune disease with multiple contributing factors and effector mechanisms. This is supported by the fact that sera from PPCM patients contain high titers of auto-antibodies against normal human cardiac tissue proteins of 37, 33, and 25 kD that was not present in the sera of patients with idiopathic cardiomyopathy (IDCM), indicating for the first time that PPCM is distinct from IDCM. In addition to the autoantibodies, the PBMC's from PPCM patients demonstrate a heightened level of fetal microchimerism, an abnormal cytokine profile, decreased levels of CD4+ CD25lo regulatory T cells, and a significant reduction in the plasma levels of progesterone, estradiol and relaxin in PPCM patients as compared with other normal pregnant non-PPCM patients. A potential role for reduced plasma levels of selenium in the pathogenesis of select PPCM patients was also noted. These findings for the first time suggest that such abnormalities may in concert lead to the initiation and perpetuation of an autoimmune process, which leads to cardiac failure and disease. Identification of the precise nature of the cardiac tissue autoantigens (currently in progress) will pave the way for the delineation of mechanism of this autoimmune disease. A working model for the pathogenesis of this disease is also described herein.

Abstract
It is critical that the diagnosis of peripartum cardiomyopathy is limited to women with congestive heart failure and decreased systolic function of the left ventricle in last month of pregnancy or within 5 months after delivery. Patients must have no pre-existing cardiac disease and no other cause for current cardiac dysfunction. The inclusion of patients before the last month of pregnancy or after 5 months postpartum introduces a large number of patients with cardiac disorders due to causes other than peripartum cardiomyopathy. Ventricular performance at rest and with exertion determines the type of management, its intensity, and duration. Patients whose ventricular function is normal at rest and with exercise or dobutamine can have their heart failure therapy tapered and ultimately discontinued after 6 to 12 months of standard treatment. Those with normal resting but abnormal stress cardiac function should continue some form of medical therapy (afterload reduction or beta-blocker) for longer periods of time, if not for life. Those with persistently abnormal ventricular function must receive optimal heart failure therapy forever and face the same relatively poor prognosis as patients with dilated cardiomyopathy from any cause. Options for management include standard heart failure therapy (digoxin, diuretics, afterload reduction, and anticoagulation), Swan-Ganz catheter monitoring and use of inotropic agents, intra-aortic balloon counterpulsation, and left ventricular assist device. Patients with peripartum cardiomyopathy are candidates for heart transplantation, assuming they meet all other criteria.

Abstract
Myocarditis is defined as inflammation of the myocardium accompanied by myocellular necrosis. Acute myocarditis must be considered in patients who present with recent onset of cardiac failure or arrhythmia. Often there is a history of an antecedent flu-like illness. Fulminant myocarditis is a distinct entity characterized by sudden onset of severe congestive heart failure or cardiogenic shock, usually following a flu-like illness. Giant cell myocarditis is a rare, frequently fatal disorder of unknown origin characterized by presence of giant cell inflammatory infiltrate in the myocardium. In recent years we have made good progress in understanding the causes, pathogenesis, natural history, diagnosis, and treatment of myocarditis. However, our knowledge is still far from complete. New information that extends our understanding of myocarditis is being reported constantly. This review summarizes recent advances in myocarditis, with an emphasis on the literature during the last year.
