RESUMO
BACKGROUND: Eisenmenger syndrome (ES) is a rare condition seen in children with congenital heart disease (CHD). It is characterized by raised pulmonary vascular resistance (PVR) arising from a shunt reversal with the presence of desaturated blood in the systemic circulation. Proper timing and early intervention in children with congenital heart disease have made the syndrome a rare occurrence. However, this cannot be said in developing countries where facilities for the diagnosis and management of children with congenital heart disease are not optimal. OBJECTIVES: The aim of this narrative review is to highlight the importance of early diagnosis and to review the new techniques in the evaluation of children with ES. It also highlights in a snapshot the state of management of ES in a developing country. METHODS: A search for published data on ES was done through several search engines such as Pubmed, google scholar citation, systematic reviews, and meta-analysis. This involves research done over the past 30 years. Keywords such as Eisenmenger'syndrome, 'congenital heart defect', 'Pulmonary hypertension', 'catherterization', 'echocardiography', and children' were used. RESULTS: This review shows the new technique in the diagnosis, aetio-pathogenesis, management and treatment of children with ES in-depth descriptive analysis and new advances in the management of children with ES. CONCLUSION: Eisenmenger syndrome is a preventable disease that can be curbed by early diagnosis and treatment of children with congenital heart disease, especially in the developing world.
CONTEXTE: Le syndrome d'Eisenmenger (SE) est une affection rare observée chez les enfants atteints de cardiopathie congénitale. Il se caractérise par une augmentation de la résistance vasculaire pulmonaire (RVP) due à l'inversion d'un shunt et à la présence de sang désaturé dans la circulation systémique. Le syndrome est devenu rare chez les enfants atteints de cardiopathie congénitale grâce à un choix judicieux du moment et à une intervention précoce. Toutefois, il n'en va pas de même dans les pays en développement où les moyens de diagnostic et de prise en charge des enfants atteints de cardiopathies congénitales ne sont pas optimaux. OBJECTIFS: L'objectif de cette revue narrative est de souligner l'importance d'un diagnostic précoce et de passer en revue les nouvelles techniques d'évaluation des enfants atteints de SE. Elle met également en lumière, sous forme d'un instantané, l'état de la prise en charge de l'ES dans un pays en développement. MÉTHODES: Une recherche de données publiées sur l'ES a été effectuée à l'aide de plusieurs moteurs de recherche tels que Pubmed, google scholar citation, revues systématiques et méta-analyses. Il s'agit de recherches effectuées au cours des 30 dernières années. Des mots clés tels que "syndrome d'Eisenmenger", "malformation cardiaque congénitale", "hypertension pulmonaire", "cathétérisme", "échocardiographie" et "enfants" ont été utilisés. RÉSULTATS: Cette revue présente les nouvelles techniques de diagnostic, d'étio-pathogénie, de prise en charge et de traitement des enfants atteints de SE, ainsi qu'une analyse descriptive approfondie et les nouvelles avancées dans la prise en charge des enfants atteints de SE. CONCLUSION: Le syndrome d'Eisenmenger est une maladie évitable qui peut être enrayée par un diagnostic et un traitement précoces des enfants atteints de cardiopathies congénitales, en particulier dans les pays en développement.

BACKGROUND: Data regarding the prognosis of Eisenmenger syndrome (ES) and effect of targeted drugs are limited. This study aimed to analyze the prognosis and impact of targeted drug therapy on the survival rate of patients with ES in the Chinese population. METHODS: The data of patients with ES referred to our hospital between January 2010 and December 2020 were retrospectively analyzed. Data included baseline demographics, echocardiographic parameters, and clinical diagnoses. All patients were followed up via telephone interviews in February 2022. The primary endpoint was mortality. RESULTS: Overall, 1,021 patients with ES were included. The 1-, 3-, 5-, 7-, 10-, and 12-year survival rates were 91.6%, 84.2%, 80.7%, 73.8%, 71.4%, and 69.9%, respectively. Patients with atrial septal defects had the best prognosis than those with ventricular septal defects, patent ductus arteriosus, and complex congenital heart disease (CHD) (P < 0.0001). Patients who visited between 2016 and 2020 received increased targeted drug therapy and had a better prognosis than those who visited between 2010 and 2015 (all P < 0.05). Cox regression analysis revealed age, pulmonary arterial systolic pressure, post-tricuspid shunt CHD, targeted drugs, and year of the first hospital visit to be predictors of death (P < 0.05). CONCLUSIONS: Survival rates associated with an increased use of combined targeted drugs significantly improved in patients with ES. However, numerous factors that predict increased mortality remain to be elucidated.

BACKGROUND: Despite advances in medical care, we still come across pregnancy in Eisenmenger syndrome. Eisenmenger syndrome represents the severe end of the spectrum for disease in pulmonary artery hypertension associated with CHD. Due to very high maternal and perinatal morbidity and mortality, pregnancy is contraindicated among these women. Current guidelines also recommend that the women who become pregnant should opt for early termination of pregnancy. Here, we present a case series of 11 women of Eisenmenger syndrome and their pregnancy outcome. METHODS: It was a retrospective analysis of 12 pregnancies among 11 women with Eisenmenger syndrome who were managed in a tertiary care referral centre of Northern India. RESULTS: The mean age of these women was 28 ± 4 years (range 22 to 36 years). Almost 80% of them (9/11) were diagnosed with Eisenmenger syndrome during pregnancy. The commonest cardiac lesion was Ventricular Septal defect (54.5%) followed by Atrial Septal defect (27.3%) and Patent Ductus arteriosus (9.1%). Only three women opted for medical termination of pregnancy, rest eight continued the pregnancy or presented late. Pregnancy complications found include pre-eclampsia (50%), abruption (22%), and fetal growth retardation (62.5%). There were three maternal deaths (mortality rate 27%) in postpartum period. CONCLUSION: This case series highlights the delay in diagnosis and treatment of CHD despite improvement in medical care. Women with Eisenmenger syndrome require effective contraception, preconceptional counselling, early termination of pregnancy, and multidisciplinary care.

BACKGROUND: To explore the outcomes of mothers with Eisenmenger syndrome (ES) and their offspring. METHODS: Pregnant women with ES admitted to the Beijing Anzhen Hospital between 2010 and 2019 were retrospectively analyzed and followed up. RESULTS: Forty-two parturient women with ES were recruited, with an average age of 26.7 years (standard deviation [SD], ±4.0 years). The average gestational age was 33.7 weeks (SD, ±2.5 weeks). The average percutaneous oxygen saturation was 84.1 (±9.2), and 40 (95.2%) had caesarean delivery. The average pulmonary artery systolic pressure was 107.5 mmHg (SD, ±20.3 mmHg). Twelve (28.6%) women experienced pulmonary hypertensive crisis; 11 (26.2%) of these women died. Regarding the offspring, the average fetal weight was 1778.1 g (SD, ±555.3 g), six (14.3%) died, and congenital heart disease was diagnosed in three (7.1%). There were significant differences in age, gestational age, percutaneous oxygen saturation, Apgar score, and heart failure between the maternal death and non-death groups (P < 0.05). Death was mainly related to pulmonary hypertensive crisis and heart failure. CONCLUSIONS: We recommend pregnancy termination if ES occurs during early pregnancy; however, patients should be informed of the risks if it occurs during late pregnancy. Multidisciplinary cooperation should be strengthened to improve the prognosis of the mothers and their offspring.

Although major breakthroughs in the field of pediatric cardiology, cardiac surgery, intervention, and overall care improved the outlook of congenital heart disease, Eisenmenger syndrome (ES) is still encountered and remains a complex clinical entity with multisystem involvement, including secondary erythrocytosis, increased thrombotic and bleeding diathesis, high arrhythmogenic risk, progressive heart failure, and premature death. Clearly, care for ES is best delivered in multidisciplinary expert centers. In this review, we discuss the considerable recent progress in understanding the complex pathophysiology of ES, means of prognostication, and improvement in clinical outcomes achieved with pulmonary arterial hypertension-targeted therapies. Additionally, we delineate areas of uncertainty in various aspects of care, discuss gaps in current evidence, and review current status in less privileged countries and propose initiatives to reduce disease burden. Finally, we propose the application of emerging technologies to enhance the delivery and quality of health care related to ES and beyond.

A young boy in his 20s presented with sudden diminution of vision in right eye 2 days ago. Best-corrected visual acuity was hand movement in right eye and 20/20 in left eye. Funduscopy demonstrated diffuse retinal opacification and swelling at the posterior pole with a cherry red spot at the macula. There was sparing of the superonasal macula with a patent cilioretinal artery. OCT showed diffuse inner retinal thickening of the temporal macula. He was diagnosed as central retinal artery occlusion with cilioretinal sparing in right eye. He was a known case of Eisenmenger syndrome secondary to a large congenital ventricular septal defect. Medical history was notable for prominent pulmonary hypertension and shortness of breath on exertion. Physical examination revealed a harsh systolic murmur. Extremities showed digital erythema and severe clubbing. Chest X-ray demonstrated cardiomegaly. Laboratory examination revealed haemoglobin-220 g/L, haematocrit-60%, serum iron-20 µg/dL.

BACKGROUND: Left main coronary artery disease secondary to pulmonary artery compression related to Eisenmenger syndrome is an under-suspected condition that can cause fatal outcomes if left untreated. It presents with typical angina but is frequently mistaken for pulmonary hypertension (PH) symptoms. It is now recognized as one of the few important causes of angina in PH. CASE PRESENTATION: A 37-year-old man with a history of unoperated atrial septal defect and Eisenmenger syndrome came to the outpatient department with a chief complaint of angina on exertion. Electrocardiogram showed regular sinus rhythm with right axis deviation, right ventricular hypertrophy, deep T-wave inversion in inferior and anterior leads suggestive of ischemia or strain, and incomplete right bundle branch block. Cardiac CT showed compression of the left main coronary artery due to a dilated main pulmonary artery. Therefore, this patient was diagnosed with Eisenmenger syndrome with left main compression due to dilated pulmonary artery. He was treated successfully with IVUS-guided stent implantation. The patient experienced marked improvement in regular activities, with no recurrence of angina symptoms. Angiography 3 months after the procedure revealed good patency of the stent, without significant stenosis. CONCLUSIONS: Left main coronary artery compression is a complication that should be suspected in patients with Eisenmenger syndrome presenting with angina symptoms. Non-invasive modalities are recommended for diagnostic evaluation, but the gold-standard technique remains coronary angiography. The best treatment is not well-established, with either myocardial revascularization or PH treatment, but a left main coronary artery stenting procedure is considered an ideal emergent treatment to provide a better quality of life for patients in this condition.

Pulmonary arterial hypertension related to congenital heart disease (PAH-CHD) affects 5% to 10% of adults with CHD and is associated with significant morbidity and mortality. PAH-CHD develops as a consequence of intracardiac or extracardiac systemic-to-pulmonary shunts that lead to pulmonary vascular remodeling through a pathologic process that is similar to other causes of PAH. Eisenmenger syndrome is the most severe phenotype of PAH-CHD and is characterized by severe elevation in pulmonary vascular resistance, with shunt reversal causing hypoxemia and central cyanosis. The primary management strategy for most patients with PAH-CHD is medical therapy, although defect closure is considered in select cases.

Eisenmenger syndrome is a dramatic complication of certain heart diseases. It is an absolute contra-indication to pregnancy because it holds a high risk of maternal-fetal mortality. Nowadays, we don´t see much of this condition, because congenital heart defects are diagnosed during childhood, infancy, or prenatally; and even if a pregnancy occurs, it is usually terminated as soon as it is diagnosed. Nevertheless, some women are willing to carry the risks that come with their condition. We report the case of a 26-year-old woman with an undiagnosed interventricular septal wall defect that evolved into Eisenmenger syndrome during her pregnancy. A successful elective C-section was done under epidural anesthesia and close monitoring. When facing this challenging situation, there are no clear guidelines, however, premature and elective delivery is paramount.

Pulmonary arterial hypertension (PAH) - a complex and progressive disease that carries significant morbidity and mortality despite optimal medical treatment. Combination therapy for PAH can be more effective than monotherapy. The present randomized trial compared the safety and efficacy of sildenafil ambrisentan combination therapy with sildenafil monotherapy. Twenty-two patients of Eisenmenger syndrome and five patients of idiopathic PAH were randomized to two arms. There was a significant improvement in NYHA functional class and mean pulmonary artery pressure, while an insignificant improving trend was observed for 6-min walk distance and oxygen saturation, following the 12 weeks of combination therapy. An upfront combination therapy was found to be safe and effective in the management of PAH patients.

Studies assessing exercise ventilatory responses during real-life exercise in pulmonary arterial hypertension (PAH) which include patients with cyanotic congenital heart disease are scarce. We assessed the ventilatory response to stairclimbing in patients with idiopathic PAH (IPAH) and congenital heart disease-associated PAH with Eisenmenger (EIS) physiology compared to healthy controls. Fifteen adults with IPAH, six EIS and 15 age and body mass index (BMI) matched controls were prospectively recruited. Participants completed spirometry and a self-paced stair-climb (48 steps) with portable cardiopulmonary exercise testing (CPET) equipment in-situ. Borg dyspnoea scores were measured at rest and on stair-climb cessation. Both IPAH and EIS groups had amplified ventilatory responses compared to Controls. The rate of increase in minute ventilation (VE) was exaggerated in EIS driven by an early increase in tidal volume (Tv) and more gradual increase in respiratory rate (RR). Peak Tv, RR, Tv: forced vital capacity (FVC) ratio, VE/VCO2 slope and stairclimb duration were significantly higher in EIS and IPAH compared to controls despite similar baseline spirometry and change in oxygen uptake on exercise. A decline in end-tidal carbon dioxide (CO2) and arterial oxygen saturations in early exercise distinguished EIS and IPAH patients. Significant correlations were observed between peak exercise Borg score and stair-climb time (r = 0.73, p = 0.002), peak end-tidal CO2 (r = -0.73, p = 0.001), peak VE (r = 0.53, p = 0.008), peak RR (r = 0.42, p = 0.011) and VE/VCO2 slope (r = 0.54, p = 0.001). Patients with IPAH and EIS have exaggerated ventilatory responses to stair-climbing compared to the controls with more severe levels of dyspnoea perception in Eisenmenger syndrome for equivalent oxygen uptake and work.

Pulmonary arterial hypertension is a common complication in patients with congenital heart disease (CHD), aggravating the natural course of the underlying defect. Pulmonary arterial hypertension (PAH) has a multifactorial etiology depending on the size and nature of the cardiac defect as well as environmental factors. Although progress has been made in disease-targeting therapy using pulmonary vasodilators to treat Eisenmenger syndrome, important gaps still exist in the evaluation and management of adult patients with CHD-associated PAH (PAH-CHD) who have systemic-to-pulmonary shunts. The choice of interventional, medical, or both types of therapy is an ongoing dilemma that requires further data. This review focuses on the evaluation and management of PAH-CHD in the contemporary era.

A 52-year-old man who was diagnosed with Eisenmenger syndrome due to a muscular-type ventricular septal defect 30 years previously, visited our emergency room after experiencing six hours of severe left flank pain and vomiting. On laboratory examination, azotemia and microscopic haematuria were identified. Contrast-enhanced computed tomography also revealed pulmonary embolism (PE) and bilateral acute renal infarction. The flank pain resolved after heparin was administered for anti-coagulation and aspiration thrombectomy was performed. The patient was discharged on warfarin as anticoagulant therapy. In this case, a paradoxical embolism was considered to have been the cause of PE and bilateral acute renal infarction in a patient with Eisenmenger syndrome.

Introduction: Eisenmenger syndrome describes a condition in which a congenital heart defect has caused severe pulmonary vascular disease, resulting in reversed (right-left) or bidirectional shunting and chronic cyanosis.Areas covered: In this paper, the progression of congenital heart defects to Eisenmenger syndrome, including early screening, diagnosis and operability are covered. The mechanisms of disease progression in Eisenmenger syndrome and management strategies to combat this, including the role of pulmonary arterial hypertension therapies, are also discussed.Expert opinion/commentary: Patients with congenital heart disease (CHD) are at increased risk of developing pulmonary arterial hypertension with Eisenmenger syndrome being its extreme manifestation. All CHD patients should be regularly assessed for pulmonary hypertension. Once Eisenmenger syndrome develops, shunt closure should be avoided. The clinical manifestations of Eisenmenger syndrome are driven by the systemic effects of the pulmonary hypertension, congenital defect and long-standing cyanosis. Expert care is essential for avoiding pitfalls and preventing disease progression in this severe chronic condition, which is associated with significant morbidity and mortality. Pulmonary arterial hypertension therapies have been used alongside supportive care to improve the quality of life, exercise tolerance and the outcome of these patients, although the optimal timing for their introduction and escalation remains uncertain.

Adult patients with uncorrected congenital heart diseases and chronic intracardiac shunt may develop Eisenmenger syndrome (ES) due to progressive increase of pulmonary vascular resistance, with significant morbidity and mortality. Acute decompensation of ES in conditions promoting a further increase of pulmonary vascular resistance, such as pulmonary embolism or pneumonia, can precipitate major arterial hypoxia and death. In such conditions, increasing systemic oxygenation with veno-venous extracorporeal membrane oxygenation (VV-ECMO) could be life-saving, serving as a bridge to treat a potential reversible cause for the decompensation, or to urgent lung transplantation. Anticipating the effects of VV-ECMO in this setting could ease the clinical decision to initiate such therapeutic strategy. Here, we present a series of equations to accurately predict the effects of VV-ECMO on arterial oxygenation in ES and illustrate this point by a case of ES decompensation with refractory hypoxaemia consecutive to an acute respiratory failure due to viral pneumonia.

Eisenmenger syndrome (ES) has been considered a cause of inoperability in patients with congenital heart disease (CHD). Even if long-standing vasodilators are efficient to reduce pulmonary vascular resistance (PVR), the best approach to grant stable repair of these patients is still unknown. We describe the case of a 28-year-old man with a diagnosis of untreated large ventricular septal defect and established ES. After few years of vasodilator therapy, the patient underwent pulmonary banding with significant reduction of his PVR. His CHD was then repaired, with clinical and functional improvement at 2-year follow-up.

Eisenmenger syndrome (ES) represents the most severe phenotype of pulmonary arterial hypertension (PAH) associated with congenital heart disease (CHD) and occurs in patients with large unrepaired shunts. Despite early detection of CHD and major advances in paediatric cardiac surgery, ES is still prevalent and requires a multidisciplinary approach by adult CHD experts in tertiary centres. Central cyanosis is the primary clinical manifestation leading to secondary erythrocytosis and various multiorgan complications that increase morbidity and affect quality of life. Close follow-up is needed to early diagnose and timely manage these complications. The primary goal of care is to maintain patients' fragile stability. Although the recent use of advanced PAH therapies has substantially improved functional capacity and increased life expectancy, long-term survival remains poor. Progressive heart failure, infectious diseases and sudden cardiac death comprise the main causes of death in patients with ES. Impaired exercise tolerance, decreased arterial oxygen saturation, iron deficiency, pre-tricuspid shunts, arrhythmias, increased brain natriuretic peptide, echocardiographic indices of right ventricular dysfunction and hospitalisation for heart failure predict mortality. Endothelin receptor antagonists are used as first-line treatment in symptomatic patients, while phosphodiesterase-5 inhibitors may be added. Due to the lack of evidence, current guidelines do not provide a clear therapeutic strategy regarding treatment escalation. Additional well-designed trials are required to assess the comparative efficacy of various PAH agents and the benefit of combination therapy. Finally, the development of a risk score is of utmost importance to guide clinical therapy.

A seven-month-old cat was referred for evaluation of exercise intolerance and open-mouth breathing. Based on ultrasonographic examination, caudal vena cava (CVC) aneurysm associated with right congestive heart failure resulting from congenital heart disease was diagnosed. Conservative treatment for alleviating pulmonary hypertension mildly improved the clinical signs and decreased the heart size and CVC aneurysm diameter. However, the improvements were transient and four months after initiating therapy, the cat developed dyspnea and uncontrollable seizures and was euthanized.

Tetralogy of Fallot is the most common cyanotic congenital heart defect consisting of an overriding aorta, right ventricular outflow obstruction, ventricular septal defect, and right ventricular hypertrophy. Without surgical management, approximately only 3% of patients survive past the age of 40 years. Cases of unoperated patients reaching adulthood have been reported; however, few studies describe treatment guidelines for surgical or therapeutic management. In this article, we report the case of a 59-year-old Hispanic male with unoperated tetralogy of Fallot presenting to our cardiology clinic for initial workup and management.

BACKGROUND: Pulmonary arterial hypertension (PAH), is a rare and progressive disease with a high morbidity and mortality. Prostanoid pulmonary vasodilators are the most effective treatment for idiopathic and connective tissue associated PAH. Nonetheless, data examining their safety and efficacy in patients with Eisenmenger syndrome the most severe form of PAH, that is, related to cyanotic congenital heart disease (CHD-PAH) remains limited. AIM: To evaluate safety and the clinical efficacy of nebulised iloprost in patients with Eisenmenger syndrome who are on maximum background oral PAH therapy. METHODS: This pilot study was a randomised, double-blind, placebo-controlled, cross-over study. Patients were randomised to receive nebulised placebo or iloprost for 12â¯weeks and were then crossed over, with a 7-14-day washout. The primary endpoint was a change in 6-minute walk distance (6MWD). RESULTS: Sixteen patients (11 females, aged 47.3⯱â¯9.8â¯year) were recruited, twelve completed the study. All were in WHO-FC III, with a resting oxygen saturation of 84 [81-87] % and a median 6MWD of 290 [260-300] m. There was no significant difference in the primary endpoint between nebulised iloprost (0[-4-9]m) and placebo (10 [-15-51]m), pâ¯=â¯0.58. There were no safety concerns with nebulised iloprost. CONCLUSIONS: Our pilot study provides preliminary evidence that the addition of nebulised iloprost to maximum oral PAH therapy did not improve the primary endpoint of 6MWD. Nebulised iloprost was well tolerated with no significant safety concerns in CHD-PAH.
