Bronchial Atresia with Eisenmenger Syndrome in a Complex Congenital Heart Disease-A Rare Coexistence: A Case Report.

BACKGROUND: Congenital bronchial atresia (CBA) is a relatively benign and uncommon pulmonary anomaly that is usually an incidental radiological finding. Bronchial atresia may also be acquired. Its association with pulmonary vascular anomalies and congenital heart disease (CHD) has been described in literature as a handful of case reports only. CASE DESCRIPTION: We report a case of a 26-year-old female having a rare coexistence of bronchial atresia with a large patent ductus arteriosus (PDA) and a small atrial septal defect (ASD), and had Eisenmenger syndrome (ES) at the time of presentation. PDA itself causes pulmonary arterial hypertension (PAH) if not corrected early within a few months of infancy. On the contrary, CBA can also lead to PAH and along with PDA may have contributed to the development of ES in our case. CONCLUSION: Timely diagnosis and treatment of CBA and its associated CHD may prevent or delay the complications occurring later on.

Evaluation of Outcomes of Pregnancy in Women with Eisenmenger Syndrome: Is There Any Prognostic Criterion?

OBJECTIVE: Pregnancy in women with Eisenmenger syndrome (ES) presents very high morbidity and mortality rates for both the mother and fetus. In this study, we aimed to evaluate the outcomes of pregnancies affected by ES. METHODS: This retrospective cohort study reviewed pregnancies in women with ES at two university hospitals over the past 10 years. The primary outcomes examined were maternal, perinatal, and pregnancy-related outcomes in women with ES. RESULTS: The study enrolled eight pregnant women diagnosed with ES. The average maternal age was 26.7 years (range 21-36 years). The causes of ES included ventricular septal defect (five patients), patent ductus arteriosus (two patients), and atrial septal defect (one patient). Four patients had been diagnosed with ES before pregnancy. Two patients died in this group; one developed right heart failure in the third trimester and unfortunately died immediately after delivery due to cardiogenic shock, and another died on the 10th postpartum day from sudden cardiac arrest despite having had a successful delivery. Four patients were diagnosed with ES during the postpartum period; none in this group died, and there were no cases of fetal mortality. We could not identify any clinical or echocardiographic predictors for postpartum mortality. The two deceased patients showed tendencies of severe right heart failure and lower oxygen saturation during the third trimester and before delivery. CONCLUSION: Despite advanced obstetric care and targeted treatments for pulmonary arterial hypertension, maternal mortality is still unacceptably high in patients with ES. No significant predictors of maternal mortality were identified.

Swyer-James-MacLeod Syndrome in a Patient with Eisenmenger Syndrome.

Swyer-James-MacLeod syndrome is characterized radiologically by hyperlucency in a single lung lobe, accompanied by reduced vascularity, alveolar hyperdistention, and air trapping, without bronchial airway obstruction. The most common congenital heart defect in childhood, ventricular septal defect, leads to irreversible pulmonary hypertension and Eisenmenger syndrome if not treated promptly. This case report presents a 25-year-old patient with Swyer-James-MacLeod syndrome and Eisenmenger syndrome. It is crucial to include Swyer-James-MacLeod syndrome in the differential diagnosis of patients with atypically distributed pulmonary emphysema and unilateral hyperlucency for early diagnosis and timely intervention.

Pseudo-subarachnoid haemorrhage: An unusual presentation of hyperviscosity syndrome.

Hyperviscosity syndrome can present with haematological, neurological or cardiovascular manifestations. The common differential diagnoses for severe headache and altered sensorium in a patient with Eisenmenger syndrome include brain abscess, meningitis, cortical venous thrombosis and subarachnoid haemorrhage (SAH). We report a patient with Eisenmenger syndrome with hyperviscosity, presenting as pseudo-SAH, which was successfully treated with phlebotomy.

Contemporary survival outcomes of congenital systemic-to-pulmonary shunt in children with borderline pulmonary vascular resistant index compared to Eisenmenger syndrome.

Pulmonary arterial hypertension (PAH) associated with congenital heart disease (PAH-CHD) is a complication that occurs after unrepaired significant systemic-to-pulmonary shunt. Treatment options for PAH-CHD-predominantly left-to-right (L-R) shunt in children with borderline-high pulmonary vascular resistant index (PVRi) have been debated. We aimed to assess the treatment and survival of children with PAH-CHD-predominantly L-R shunt with borderline to high PVRi, using Eisenmenger syndrome (ES) for comparison. In 1995-2021, a total of 142 patients with ES and 192 children with PAH-CHD-predominantly L-R shunt were eligible for our analysis. The PVRi in ES patients was 26.7 ± 16.8 WU m2. Most patients (91%) received PAH-targeted therapy. Of the 192 children with PAH-CHD-predominantly L-R shunt, the baseline PVRi was 9.2 ± 5.8 WU m2. A total of 64 patients (33.3%) had borderline PVRi (4-8 WU m2) and 98 patients (51%) had high PVRi (> 8 WU m2). Most patients (88.5%) responded to acute pulmonary vasodilatory testing and underwent repair, with 158 undergoing defect closure and 12 having fenestrated closure. A treat-and-repair strategy was used in 33 children (17.1%). The 10- and 15-year survival rates for patients with ES were 79.3% and 72.4%, respectively, which was significantly inferior to children with borderline PVRi [97.3% and 87.8% (p = 0.02)]; and high PVRi [91.6% and 89.5% (p = 0.06)], respectively. The survival rate of children receiving treat-and-repair was slightly higher than that of ES (p = 0.16). The independent mortality risk in children with PAH-CHD-predominantly L-R shunt was persistent PAH following the defect correction (adjusted hazard ratio 5.8, 95% CI 1.7-19.9, p = 0.005).Trial registration: TCTR20200420004.

Perioperative Management of an Obstetric Patient with Eisenmenger Syndrome and Pre-Eclampsia Using Milrinone.

ABSTRACT: Pregnancy in a patient with pulmonary hypertension carries a high risk of mortality. It poses multiple problems in the management of pregnancy, labor, and postpartum, thereby emphasizing the need for a multidisciplinary team for a successful outcome. We describe the successful management of a case of Eisenmenger syndrome who developed pre-eclampsia during her 28 weeks of pregnancy. As far as our knowledge, this is the first case report that describes the use of milrinone in a parturient for a successful outcome.

Cyanotic Nephropathy in an Adult Patient with Eisenmenger Syndrome: A Case Report and Literature Review.

INTRODUCTION: Cyanotic nephropathy, a rare disease characterized by proteinuria, decreased estimated glomerular filtration rate, thrombocytopenia, polycythemia, and hyperuricemia, may occasionally be secondary to cyanotic congenital heart disease (CHD). There are currently no detailed diagnostic criteria or treatments for cyanotic nephropathy, owing to its extremely low incidence. Eisenmenger syndrome (ES) was initially defined by Paul Wood in pathophysiologic terms as "pulmonary hypertension (PH) at the systemic level, caused by a high pulmonary vascular resistance, with a reversed or bidirectional shunt at the aorto-pulmonary, ventricular, or atrial level." It typically develops in the presence of large, unrepaired atrial or ventricular septal defects, arterial shunts, or complex forms of CHD and is the most severe hemodynamic phenotype of pulmonary arterial hypertension associated with CHD. This study aimed to outline the case of an ES patient who developed cyanotic nephropathy and successfully achieved clinical remission through primary disease treatment and symptomatic management. Overall, this case expands our understanding of cyanotic nephropathy and lays a theoretical reference for the treatment of ES. CASE PRESENTATION: A 33-year-old Chinese female attended the outpatient department with abnormal urine test results over the past two and a half years. Following a comprehensive medical history collection, she underwent the necessary tests. Cardiac color ultrasound displayed a significant widening of the pulmonary artery and PH (severe), as well as mild tricuspid regurgitation and patent ductus arteriosus. The results of the kidney biopsy, combined with clinical findings, suggested a high risk of polycythemia-related kidney disease. She was eventually diagnosed with cyanotic nephropathy and ES. Her symptoms were relieved following symptomatic treatment, such as the administration of ambrisentan, febuxostat, and home oxygen therapy. Her follow-up visit at 6 months demonstrated improvements in hyperuricemia and a significant increase in physical strength. CONCLUSION: Cyanotic nephropathy is a rare condition in adults. Kidney biopsy remains the gold standard of diagnosis for various nephropathies. Active treatment of CHD and alleviating hypoxia may be pivotal for the treatment of cyanotic nephropathy.

Acquired Cardiovascular Diseases in Patients with Pulmonary Hypertension Due to Congenital Heart Disease: A Case Report.

Background: Advances in the diagnosis and treatment of congenital heart diseases (CHDs) have resulted in improved survival rates for CHD patients. Up to 90% of individuals with mild CHD and 40% with complex CHD now reach the age of 60. Previous studies have indicated an elevated risk of atherosclerotic cardiovascular disease (ASCVD) and associated risk factors, morbidity, and mortality in adults with congenital heart disease (ACHD). However, there were no comprehensive guidelines for the prevention and management of acquired cardiovascular diseases (CVDs) in ACHD populations until recently. Case presentation: A 55-year-old man with Eisenmenger syndrome and comorbidities (arterial hypertension, heart failure, dyslipidemia, hyperuricemia, and a history of pulmonary embolism (PE)) presented with progressive breathlessness. The electrocardiogram (ECG) revealed signs of right ventricle (RV) hypertrophy and overload, while echocardiography showed reduced RV function, RV overload, and severe pulmonary hypertension (PH) signs, and preserved left ventricle (LV) function. After ruling out a new PE episode, acute coronary syndrome (ACS) was diagnosed, and percutaneous intervention was performed within 24-48 h of admission. Conclusions: This case highlights the importance of increased awareness of acquired heart diseases in patients with pulmonary hypertension due to CHD.

Triple vasodilator therapy in pulmonary arterial hypertension associated with congenital heart disease.

OBJECTIVE: This study assessed the long-term effects of triple therapy with prostanoids on patients with pulmonary arterial hypertension associated with congenital heart disease (PAH-CHD), as there is limited information on the safety and efficacy of this treatment approach. METHODS: A retrospective cohort study was conducted on patients with PAH-CHD who were actively followed up at our centre. All patients were already receiving dual combination therapy at maximum doses. Clinical characteristics, including functional class (FC), 6-minute walking test distance (6MWTD) and N-terminal pro-brain natriuretic peptide (NT-proBNP) levels, were documented before initiating triple therapy and annually for a 2-year follow-up period. RESULTS: A total of 60 patients were included in the study, with a median age of 41 years and 68% being women. Of these, 32 had Eisenmenger syndrome, 9 had coincidental shunts, 18 had postoperative PAH and 1 had a significant left-to-right shunt. After 1 year of triple combination initiation, a significant improvement in 6MWTD was observed (406 vs 450; p=0.0027), which was maintained at the 2-year follow-up. FC improved in 79% of patients at 1 year and remained stable in 76% at 2 years. NT-proBNP levels decreased significantly by 2 years, with an average reduction of 199 ng/L. Side effects were experienced by 33.3% of patients but were mostly mild and manageable. Subgroup analysis showed greater benefits in patients without Eisenmenger syndrome and those with pre-tricuspid defects. CONCLUSIONS: Triple therapy with prostanoids is safe and effective for patients with PAH-CHD, improving FC, 6MWTD and NT-proBNP levels over 2 years. The treatment is particularly beneficial for patients with pre-tricuspid defects and non-Eisenmenger PAH-CHD.

Lung infarction secondary to infected pulmonary arterial thrombosis in a patient with Eisenmenger's syndrome.

A case is presented where a patient with Eisenmenger's syndrome is successfully treated for infection of chronic pulmonary arterial thrombosis with good effect. The evidence for antibiotic and anticoagulant therapy in this patient group is discussed.

Intravascular Ultrasound-Guided Stent Implantation in the Left Main Coronary Artery Extrinsic Compression by Pulmonary Artery Aneurysm Due to Eisenmenger Syndrome.

Pulmonary arterial hypertension (PAH) is a profoundly destructive condition marked by the gradual narrowing and restructuring of small pulmonary arteries, leading to a rise in pulmonary vascular resistance (PVR), causing right-sided heart failure and, ultimately, mortality. During more advanced stages of this disease, patients may present with rare manifestations of pulmonary artery aneurysm (PAA) which are exertional chest pain, and hoarseness. The left main coronary artery compression (LMCA-Co) has been an increasingly recognized and possibly life-threatening entity in patients with severe PAH. The lack of well-established decision-making strategies for the management of both PAA and LMCA-Co has been remained as an unsolved issue in this setting. In this report, we present a case of percutaneous intervention of LMCA-Co with the guidance of intracoronary imaging in a patient with patent ductus arteriosus-Eisenmenger syndrome. Percutaneous intervention with intravascular guidance appears to be a safe and effective option for relieving symptoms and achieving positive clinical outcomes in patients with LMCA-Co.

Eisenmenger Syndrome: A Revisit of a Hidden but Catastrophic Disease.

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.

Pregnancy in women with congenital heart disease: a focus on management and preventing the risk of complications.

INTRODUCTION: Congenital heart disease (CHD) is the most common cardiac disorder in pregnancy in the western world (around 80%). Due to improvements in surgical interventions more women with CHD are surviving to adulthood and choosing to become pregnant. AREAS COVERED: Preconception counseling, antenatal management of CHDs and strategies to prevent maternal and fetal complications.Preconception counseling should start early, before the transition to adult care and be offered to both men and women. It should include the choice of contraception, lifestyle modifications, pre-pregnancy optimization of cardiac state, the chance of the child inheriting a similar cardiac lesion, the risks to the mother, and long-term prognosis. Pregnancy induces marked physiological changes in the cardiovascular system that may precipitate cardiac complications. Risk stratification is based on the underlying cardiac disease and data from studies including CARPREG, ZAHARA, and ROPAC. EXPERT OPINION: Women with left to right shunts, regurgitant lesions, and most corrected CHDs are at lower risk and can be managed in secondary care. Complex CHD, including systemic right ventricle need expert counseling in a tertiary center. Those with severe stenotic lesions, pulmonary artery hypertension, and Eisenmenger's syndrome should avoid pregnancy, be given effective contraception and managed in a tertiary center if pregnancy does happen.

Pseudoaneurysm after aortopulmonary window repair and bilateral lung transplantation for eisenmenger syndrome: a case report.

BACKGROUND: Aortopulmonary window (APW) is a rare congenital cardiac anomaly characterized by communication between the main pulmonary artery and ascending aorta. There are various surgical techniques, and the short- and long-term results are excellent if the surgical repair is performed early in life. To our knowledge, there have been no reports of pseudoaneurysm after APW repair. Herein, we present a case of a 30-year-old woman with an ascending aortic pseudoaneurysm found at the site of APW repair nine months after the APW repair and bilateral lung transplantation. CASE PRESENTATIONS: A 30-year-old woman presented with APW and Eisenmenger syndrome. The patient underwent APW repair and bilateral lung transplantation. We transected the communication between the aorta and pulmonary artery and closed the aortic side directly with strips of felts. Nine months after the surgery, the patient complained of chest pain. Cardiac computed tomography revealed an ascending aortic pseudoaneurysm at the anastomotic site. Emergent graft replacement of the ascending aorta was performed and the postoperative course was uneventful. CONCLUSIONS: We have presented a case of a pseudoaneurysm at the anastomotic site after APW repair and bilateral lung transplantation. The choice of surgical technique should be based on the patient's background requiring lung transplantation, and in these cases close postoperative follow-up is required.

Management and outcomes of pulmonary artery hypertension and Eisenmenger syndrome during pregnancy: a prospective observational cohort study.

OBJECTIVES: Maternal-fetal morbidity and mortality among pregnant women with pulmonary artery hypertension (PAH) and Eisenmenger syndrome are unacceptable, and management decision-making in these clinical scenarios remains debatable. This study aimed to compare and analyse clinical characteristics, management and pregnancy outcomes in PAH and Eisenmenger syndrome. DESIGN: Prospective observational cohort study. SETTINGS: A large tertiary care university hospital. PATIENTS: Thirty patients with pulmonary artery hypertension and 20 patients with Eisenmenger syndrome. METHODS: Data pertaining to clinical characteristics, anaesthetic, medical and obstetric management, and outcomes in pregnancy complicated by PAH and Eisenmenger syndrome were collected between July 2020 and June 2022. Each treating unit followed its management protocol in consultation with the multidisciplinary team. MAIN OUTCOME MEASURES: Maternal mortality and morbidity. RESULTS: Maternal mortality was lower in the PAH group (6.6% versus 15%; p = 0.33). All mortalities were in the postpartum period. The incidence of new-onset or exacerbation of heart failure (23.3% versus 60%; p = 0.009) and hypoxaemia (13.3% versus 50%; p = 0.005) were significantly lower in the PAH group. In the Eisenmenger syndrome group, a significantly higher number of women received pulmonary hypertension and heart failure medications. Prematurity and neonatal intensive care unit admission were frequently noticed in Eisenmenger syndrome, whereas perinatal mortality, birthweight and APGAR score were comparable. CONCLUSIONS: Fetomaternal outcomes are inferior in Eisenmenger syndrome compared with PAH and are either lower or comparable to those reported from contemporary cohorts of developed nations.

Impact of current targeted drug therapy on the prognosis of Eisenmenger syndrome: A large-scale retrospective analysis.

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.

Characteristics, treatments and survival of pulmonary arterial hypertension associated with congenital heart disease in China: Insights from a national multicenter prospective registry.

BACKGROUND: The purpose of this registry was to provide insights into the characteristics, treatments and survival of patients with PAH-CHD in China. METHODS: Patients diagnosed with PAH-CHD were enrolled in this national multicenter prospective registry. Baseline and follow-up data on clinical characteristics, PAH-targeted treatments and survival were collected. RESULTS: A total of 1060 PAH-CHD patients (mean age 31 years; 67.9% females) were included, with Eisenmenger syndrome (51.5%) being the most common form and atrial septal defects (37.3%) comprising the most frequent underlying defect. Approximately 33.0% of the patients were in World Health Organization functional class III to IV. The overall mean pulmonary arterial pressure and pulmonary vascular resistance were 67.1 (20.1) mm Hg and 1112.4 (705.9) dyn/s/cm5, respectively. PAH-targeted therapy was utilized in 826 patients (77.9%), and 203 patients (19.1%) received combination therapy. The estimated 1-, 3-, 5-, and 10-year survival rates of the overall cohort were 96.9%, 92.9%, 87.6% and 73.0%, respectively. Patients received combination therapy had significantly better survival than those with monotherapy (p = 0.016). NT-proBNP >1400 pg/ml, SvO2 ≤ 65% and Borg dyspnea index ≥ 3 and PAH-targeted therapy were independent predictors of mortality. Hemoglobin > 160g/L was a unique predictor for mortality in Eisenmenger syndrome. CONCLUSIONS: Chinese PAH-CHD patients predominantly exhibit Eisenmenger syndrome and have significantly impaired exercise tolerance and right ventricular function at diagnosis, which are closely associated with long-term survival. PAH-targeted therapy including combination therapy showed a favorable effect on survival in PAH-CHD. The long-term survival of Chinese CHD-PAH patients remains to be improved.
