J Thromb Haemost 2024:S1538-7836(24)00361-1. [PMID: 38908831 DOI: 10.1016/j.jtha.2024.05.036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2024] [Revised: 05/23/2024] [Accepted: 05/29/2024] [Indexed: 06/24/2024]
Abstract
BACKGROUND Thrombocytopenia is common for patients in the intensive care unit (ICU) and is associated with adverse outcomes. ICU thrombocytopenia in pediatric patients who underwent cardiac surgeries with cardiopulmonary bypass (CPB) is inadequately studied. OBJECTIVES We aimed to investigate the incidence, risk factors, and prognostic role of ICU thrombocytopenia after congenital cardiac surgeries with CPB. METHODS A retrospective study involving 11 761 patients was conducted. Patients were categorized into 4 groups of thrombocytopenia based on platelet counts tested during ICU: non (>150 × 109/L), mild (100-150 × 109/L), moderate (50-100 × 109/L), and severe (<50 × 109/L). Logistic and Cox regression analyses were utilized to explore the risk factors of thrombocytopenia and the association of ICU thrombocytopenia with 30-day mortality. RESULTS ICU thrombocytopenia was observed in 4007 patients (34.1%), with mild, moderate, and severe thrombocytopenia occurring in 2773 (23.6%), 987 (8.4%), and 247 (2.1%) patients, respectively. Younger age, cyanotic congenital heart disease, CPB duration, and preoperative laboratory findings (red blood cell, thrombocytopenia, red cell distribution width, hematocrit, and coagulation disorder) were identified as independent risk factors of ICU thrombocytopenia. Patients with moderate (hazard ratio [95% CI]: 11.38 [3.02-42.87]; P < .001) and severe thrombocytopenia (hazard ratio [95% CI]: 49.54 [13.11-187.14]; P < .001) had a significantly higher risk of 30-day mortality. Furthermore, with the increase in the severity of ICU thrombocytopenia, there was an incremental increase in the incidence of postoperative critical bleeding and thrombosis, perioperative blood transfusions, length of ICU stays, and duration of mechanical ventilation. CONCLUSION ICU thrombocytopenia occurred in one-third of children after congenital cardiac surgery with CPB, and it was associated with multiple adverse outcomes.

Pilot Assessment of Platelet Thrombus Area and Contractile Force in Pediatric Congenital Heart Surgery Patients Using a Microfluidic Device. J Cardiothorac Vasc Anesth 2024:S1053-0770(24)00389-6.

Abstract
OBJECTIVES This work was designed to evaluate maximum platelet contractile force and thrombus area before and after cardiopulmonary bypass (CPB) in pediatric patients having congenital heart disease (CHD) surgery using a microfluidic device. DESIGN A prospective cohort study was designed. SETTING The work took place at an academic medical center. PARTICIPANTS Twenty pediatric CHD patients ≤8 years of age with expected CPB time >30 minutes were enrolled. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Blood was collected at baseline and post-CPB. Maximum platelet contractile force and thrombus area were evaluated in vitro using a microfluidic device (ATLAS PST). Post-CPB samples were supplemented with recombinant von Willebrand factor (rVWF) to explore the impact on contractile force and thrombus area. At baseline, the maximum thrombus area was 0.06 (0.05, 0.07), and the maximum force was 123.3 nN (68.4, 299.5). Linear mixed-effects regression models showed that the maximum thrombus area was larger post-CPB and post-CPB + rVWF compared with pre-CPB (estimated coefficient [Est] = 0.04, p = 0.002; Est = 0.09, p < 0.001, respectively). The maximum thrombus area was also larger post-CPB + rVWF compared with post-CPB (Est = 0.04, p = 0.001). Force was higher post-CPB + rVWF compared with pre-CPB (Est = 173.32, p = 0.044). CONCLUSIONS In pediatric CHD patients, microfluidic testing demonstrated that platelet thrombus area increased slightly after CPB, while platelet contractile force did not change. In vitro addition of rVWF further increased thrombus area, suggesting augmentation of primary hemostasis. Microfluidic assessment of platelet contractile force and thrombus area in pediatric CHD patients appears feasible and can demonstrate changes after CPB. Further studies are needed to determine its accuracy, clinical utility, and normal values for pediatric patients.

Abstract
Many aspects of thrombopoiesis, the release of platelets from megakaryocytes (Mks), remain under debate, including where this process occurs. Murine lung in situ -microscopy studies suggested that a significant fraction of circulating platelets were released from lung-entrapped, marrow-derived Mks. We now confirm these in situ studies that endogenous mMks are entrapped in the lungs and show that intravenously infused in vitro -differentiated, mature murine (m) and human (h) Mks are similarly entrapped followed by shedding of their cytoplasm over ∼30 minutes with a peak number of released platelets occurring 1.5-4 hours later. However, while infused Mks from both species shed large intrapulmonary cytoplasmic fragments that underwent further processing into platelet-sized fragments, the two differed: many mMks escaped from and then recycled back to the lungs, while most hMks were enucleated upon first intrapulmonary passage. Infused immature hMks, inflammatory hMks, umbilical cord-blood-derived hMks and immortalized Mk progenitor cell (imMKCL)-derived hMks were also entrapped in the lung of recipient mice, and released their cytoplasm, but did so to different degrees. Intraarterial infused hMks resulted in few Mks being entrapped in tissues other than the lungs and was accompanied by a blunted and delayed rise in circulating human platelets. These studies demonstrate that the lung entraps and processes both circulating Mks and released large cytoplasmic fragments consistent with a recent lung/heart murine study and support a pulmonary-centric "catch-and-release" model of thrombopoiesis. Thus, thrombopoiesis is a drawn-out process with the majority of cytoplasmic processing derived from Mks occurring in the pulmonary bed. Key Points Infused in vitro -differentiated megakaryocytes synchronously release cytoplasmic fragments highly selectively in the pulmonary bed. Large, released megakaryocyte fragments recycle to the lungs, undergo further fission, terminally form platelets.

Abstract
Chronic mountain sickness is a maladaptive syndrome that affects individuals living permanently at high altitude and is characterized primarily by excessive erythrocytosis (EE). Recent results concerning the impact of EE in Andean highlanders on clotting and the possible promotion of hypercoagulability, which can lead to thrombosis, were contradictory. We assessed the coagulation profiles of Andeans highlanders with and without excessive erythrocytosis (EE+ and EE-). Blood samples were collected from 30 EE+ and 15 EE- in La Rinconada (Peru, 5100-5300 m a.s.l.), with special attention given to the sampling pre-analytical variables. Rotational thromboelastometry tests were performed at both native and normalized (40%) haematocrit using autologous platelet-poor plasma. Thrombin generation, dosages of clotting factors and inhibitors were measured in plasma samples. Data were compared between groups and with measurements performed at native haematocrit in 10 lowlanders (LL) at sea level. At native haematocrit, in all rotational thromboelastometry assays, EE+ exhibited hypocoagulable profiles (prolonged clotting time and weaker clot strength) compared with EE- and LL (all P < 0.01). At normalized haematocrit, clotting times were normalized in most individuals. Conversely, maximal clot firmness was normalized only in FIBTEM and not in EXTEM/INTEM assays, suggesting abnormal platelet activity. Thrombin generation, levels of plasma clotting factors and inhibitors, and standard coagulation assays were mostly normal in all groups. No highlanders reported a history of venous thromboembolism based on the dedicated survey. Collectively, these results indicate that EE+ do not present a hypercoagulable profile potentially favouring thrombosis.

Abstract
The number of adults with congenital heart defects (CHD) is steadily rising and amounts to approximately 360,000 in Germany. CHD is often associated with pulmonary hypertension (PH), which may develop early in untreated CHD. Despite timely treatment of CHD, PH not infrequently persists or recurs in older age and is associated with significant morbidity and mortality.The revised European Society of Cardiology/European Respiratory Society 2022 guidelines for the diagnosis and treatment of PH represent a significant contribution to the optimized care of those affected. However, the topic of "adults with congenital heart disease" is addressed only relatively superficial in these guidelines. Therefore, in the present article, this topic is commented in detail from the perspective of congenital cardiology.

Abstract
Background Congenital heart disease (CHD) is one of the leading causes of mortality in India, with the majority being attributed to cyanotic conditions. Hence, it is crucial to assess the factors that play a significant role in patient prognosis in heart defects of a child. The present cross-sectional study assessed the prevalence of thrombocytopenia in patients with cyanotic congenital heart defects (CCHD). The objectives of our study were to assess the levels of platelets in various cyanotic congenital heart defects and then infer the prevalence of thrombocytopenia in these patients as a whole. Methodology The study population comprised children aged fifteen days to twelve years with two-dimensional (2D) echocardiography confirmation of CHD; those who were critically ill, had proven sepsis, and were not willing to participate in the study were excluded. Blood samples of enrolled patients were obtained and collected in ethylenediamine tetraacetic acid (EDTA) tubes for assessment. The prevalence was then calculated. Results were obtained and interpreted based on these observations. Result Out of 268 children with CHD, 52 reported thrombocytopenia, and the prevalence rate was found to be 19.4. The comparative analysis of thrombocytopenia showed a significant p-value only in cases with total anomalous pulmonary venous connection (TAPVC). Conclusion Patients with cyanotic congenital heart defects are often diagnosed with various hematological derangements, and while hemoglobin levels are usually seen to rise, significant thrombocytopenia is reported in these patients. The low platelet counts often pose a risk peri-surgically and can also affect the surgical outcomes of the patient. Therefore, it is imperative to study further the relationship between thrombocytopenia and an independent risk factor for patient prognosis in patients of CCHD.

Abstract
OBJECTIVES Nailfold video-capillaroscopy (NVC) is an inexpensive method of assessing microcirculation. We reviewed the literature to assess whether changes to the nailfold capillaries exist in patients with cardiovascular disease (CVD). METHODS We searched PubMed, Scopus and Cochrane Library databases for original research articles relating to the use of noninvasive microvascular assessment in patients with CVD. Methodological quality was assessed with the 'Quality Assessment Tool for Observational Cohort and Cross-sectional Studies.' The results obtained from NVC were analysed qualitatively and compared with other forms of microvascular assessment. RESULTS In total 2759 articles were screened, of which 22 studies involving 562 patients (~40% women) with CVD were included. Mean age ranged between 3.7-68.4 years (cases) and 4.0-58.0 years (controls). Reduced capillary density and increased capillary dimensions were seen in patients with pulmonary arterial hypertension (PAH). Among patients with systemic sclerosis, advanced scleroderma patterns can be used to identify patients with or at risk of developing PAH. Functional nailfold changes precede structural changes in patients with hypertension. However, the studies were heterogeneous in the diagnosis of disease and the measurement of nailfold parameters. Most studies did not exclude conditions with altered nailfold features, and only one study performed a power calculation. Furthermore, abnormal nailfold findings are present in patients without systemic disease. CONCLUSIONS Structural and functional changes to the nailfold are a feature of established CVD and precede the development of PAH. However, heterogeneity in measurement and abnormal findings in healthy participants limit their use in the wider population.

Abstract
Background Coagulation abnormality is a significant complication and cause of mortality in children with uncorrected congenital heart defects (CHD). The aim of this study was to determine the prevalence of coagulation abnormalities and the associated factors in children with uncorrected CHD. Method A cross sectional study conducted to determine the prevalence of coagulation abnormalities among 70 children with uncorrected CHD aged six months to 17 years and 70 age and sex matched apparently healthy controls. Coagulation abnormalities was determined using complete blood count, prothrombin time, activated partial thromboplastin time and D-dimer assay. Results The prevalence of coagulation abnormalities among children with CHD and controls was 37.1% and 7.1% respectively. Children with Cyanotic CHD had a significantly higher prevalence of coagulation abnormalities compared to children with Acyanotic CHD (57.1% versus 17.1%). Haematocrit and oxygen saturation levels were significantly associated with coagulation abnormalities. Conclusion This study affirms that coagulation abnormalities are frequent in children with uncorrected CHD. Oxygen saturation and haematocrit are risk factors of coagulation abnormalities. Routine coagulation screen is recommended especially in children with cyanotic congenital heart defects to improve their quality of life and reduce morbidity and mortality while awaiting definitive surgeries.

Mohammadi H, Mohammadpour Ahranjani B, Aghaei Moghadam E, Kompani F, Mirbeyk M, Rezaei N. Hematological indices in pediatric patients with acyanotic congenital heart disease: a cross-sectional study of 248 patients. EGYPTIAN JOURNAL OF MEDICAL HUMAN GENETICS 2022; 23:47. [PMID: 37521840 PMCID: PMC8901268 DOI: 10.1186/s43042-022-00262-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Accepted: 01/30/2022] [Indexed: 11/30/2022] Open
Abstract
Background Congenital heart disease CHD is a significant cause of mortality and morbidity in children worldwide. Patients with congenital heart disease may develop hematological problems, including thrombocytopenia and neutropenia. In addition, several studies indicate the higher frailty of patients with CHDs to infections and malignancies. Nevertheless, the mechanisms of immune system changes in these patients have remained in the shadow of uncertainty. Moreover, very few studies have worked on cytopenia in CHD. This study has assessed the frequency of thrombocytopenia, neutropenia, lymphopenia, and anemia in pediatric patients with acyanotic congenital heart disease ACHD prior to open-heart surgery. Methods This cross-sectional study was handled in the Pediatric Cardiology Clinic, Tehran University of Medical Sciences, during pre-operation visits from 2014 till 2019. Two hundred forty-eight children and adolescents with acyanotic congenital heart disease before open-heart surgery met the criteria to enter the study. Results A total of 191 (76.7%) patients with Ventricular Septal Defects (VSD), 37 (14.85%) patients with Atrial Septal Defects (ASD), and 20 (8.11%) patients with Patent Ductus Arteriosus (PDA) were enrolled in this study. The median age was 23.87 months. Thrombocytopenia and neutropenia were found, respectively, in 3 (1.2) and 23 (9.2%) patients. Hemoglobin level and lymphocyte count were significantly lower in patients with neutropenia than patients with normal neutrophil count (P value = 0.024 and P value = 0.000). Significant positive correlations were found between neutropenia and anemia. There were no correlations between neutrophil count and Platelets. Also, anemia was found in 48 patients (19.3%). The study also found a statistically significant correlation between the co-existence of VSD and neutropenia in the patients (P value = 0.000). Conclusion Although most were mildly neutropenic, there was a significant correlation between neutropenia and Ventricular Septal Defect compared to PDA and ASD groups. Regarding the importance of neutropenia to affect the prognosis of congenital heart defects in infections, it is important to consider further studies on the status of immune system function in these patients.

Abstract
Haemoptysis represents one of the most severe major bleeding manifestations in the clinical course of pulmonary arterial hypertension (PAH) associated with congenital heart disease (CHD). Accumulating evidence indicates that dysfunction of the pulmonary vascular bed in the setting of PAH predisposes patients to increased hemorrhagic diathesis, resulting in mild to massive and life-threatening episodes of haemoptysis. Despite major advances in PAH targeted treatment strategies, haemoptysis is still correlated with substantial morbidity and impaired quality of life, requiring a multidisciplinary approach by adult CHD experts in tertiary centres. Technological innovations in the field of diagnostic and interventional radiology enabled the application of bronchial artery embolization (BAE), a valuable tool to efficiently control haemoptysis in modern clinical practice. However, bleeding recurrences are still prevalent, implying that the optimum management of haemoptysis and its implications remain obscure. Moreover, regarding the use of oral anticoagulation in patients with haemoptysis, current guidelines do not provide a clear therapeutic strategy due to the lack of evidence. This review aims to discuss the main pathophysiological mechanisms of haemoptysis in PAH-CHD, present the clinical spectrum and the available diagnostic tools, summarize current therapeutic challenges, and propose directions for future research in this group of patients.

Abstract
PURPOSE OF REVIEW Adults with congenital heart disease (ACHD) are a complex and growing population that presents numerous challenges for anesthetic management. This review summarizes special considerations for anesthetic management in ACHD. RECENT FINDINGS The adult patient with congenital heart disease may require anesthetic care for multiple surgeries and interventions throughout their lifetime. The cardiac and extracardiac manifestations of ACHD have important perioperative implications that affect anesthetic management. Recent American Heart Association/American College of Cardiology and European Society of Cardiology guidelines endorse a multidisciplinary, team-based approach to care. The cardiac anesthesiologist, endorsed as part of this multidisciplinary team, must have a thorough understanding of congenital heart disease pathophysiology and common extra-cardiac manifestations of ACHD. Safe anesthetic management in adult congenital heart disease should incorporate a multi-disciplinary approach to patient care. Anesthesiologists and centers with special expertise in ACHD care should be utilized or consulted whenever possible.

Abstract
A high prevalence of heavy menstrual bleeding (HMB) has been reported in women with Fontan circulation. Cyanosis has been reported to contribute to HMB, and menstruation has been suggested to affect cardiac status in women with congenital heart disease. This study aimed to evaluate the relationship between the amount of menstrual flow and cardiac status in women with Fontan circulation.Twenty women who had undergone the Fontan procedure were prospectively investigated and the amount of their menstrual flow was evaluated using a questionnaire. Participants were divided into two groups-small and large menstrual bleeding groups-and their clinical data, including the results of hematological tests and echocardiographic findings, were evaluated.One (5%) woman showed primary amenorrhea. Eight of the remaining 19 (42%) women were included in the large menstrual bleeding group. Women with large menstrual bleeding showed a significantly higher hematocrit level (47.1% [36.2%-50.3%] versus 42.1% [35.3%-44.9%], P = 0.006) and longer QRS duration (106 [92-172] ms versus 88 [78-140] ms, P = 0.008), as well as a lower fractional area change (37.4% [35.6%-47.2%] versus 47.0% [38.2%-55.7%], P = 0.010) and global longitudinal strain (-10.5% [-14.9% to -6.6%] versus -13.9% [-20.5% to -7.8%], P = 0.041) of the dominant ventricle on echocardiography, than women with small bleeding.Erythrocytosis, longer QRS duration, and reduced ventricular function were related to increased menstrual bleeding in women with Fontan circulation. These functions may be interrelated with the amount of menstrual flow in such women.

Abstract
Extracorporeal membrane oxygenation (ECMO) is a life-saving support for cardio-respiratory function. Over the last 50 years, the extracorporeal field has faced huge technological progress. However, despite the improvements in technique and materials, coagulation problems are still the main contributor to morbidity and mortality of ECMO patients. Indeed, the incidence and survival rates of the main hemorrhagic and thrombotic complications in neonatal respiratory ECMO are relevant. The main culprit is related to the intrinsic nature of ECMO: the contact phase activation. The exposure of the human blood to the non-endothelial surface triggers a systemic inflammatory response syndrome, which chronically activates the thrombin generation and ultimately leads to coagulative derangements. Pre-existing illness-related hemostatic dysfunction and the peculiarity of the neonatal clotting balance further complicate the picture. Systemic anticoagulation is the management's mainstay, aiming to prevent thrombosis within the circuit and bleeding complications in the patient. Although other agents (i.e., direct thrombin inhibitors) have been recently introduced, unfractionated heparin (UFH) is the standard of care worldwide. Currently, there are multiple tests exploring ECMO-induced coagulopathy. A combination of the parameters mentioned above and the evaluation of the patient's underlying clinical context should be used to provide a goal-directed antithrombotic strategy. However, the ideal algorithm for monitoring anticoagulation is currently unknown, resulting in a large inter-institutional diagnostic variability. In this review, we face the features of the available monitoring tests and approaches, mainly focusing on the role of point-of-care (POC) viscoelastic assays in neonatal ECMO. Current gaps in knowledge and areas that warrant further study will also be addressed.

Abstract
BACKGROUND Pulmonary arterial hypertension (PAH) is common in congenital heart disease (CHD). Because clinical-trial data on PAH associated with CHD (PAH-CHD) remain limited, registry data on the long-term course are essential. This analysis aimed to update information from the COMPERA-CHD registry on management strategies based on real-world data. METHODS The prospective international pulmonary hypertension registry COMPERA has since 2007 enrolled more than 10,000 patients. COMPERA-CHD is a sub-registry for patients with PAH-CHD. RESULTS A total of 769 patients with PAH-CHD from 62 specialized centers in 12 countries were included into COMPERA-CHD from January 2007 through September 2020. At the last follow-up in 09/2020, patients [mean age 45.3±16.8 years; 512 (66%) female] had either post-tricuspid shunts (n=359; 46.7%), pre-tricuspid shunts (n=249; 32.4%), complex CHD (n=132; 17.2%), congenital left heart or aortic valve or aortic disease (n=9; 1.3%), or miscellaneous CHD (n=20; 2.6%). The mean 6-minute walking distance was 369±121 m, and 28.2%, 56.0%, and 3.8% were in WHO functional class I/II, III or IV, respectively (12.0% unknown). Compared with the previously published COMPERA-CHD data, after 21 months of follow-up, the number of included PAH-CHD patients increased by 91 (13.4%). Within this group the number of Eisenmenger patients rose by 39 (16.3%), the number of "Non-Eisenmenger PAH" patients by 45 (26.9%). Currently, among the 674 patients from the PAH-CHD group with at least one follow-up, 450 (66.8%) received endothelin receptor antagonists (ERA), 416 (61.7%) PDE-5 inhibitors, 85 (12.6%) prostacyclin analogues, and 36 (5.3%) the sGC stimulator riociguat. While at first inclusion in the COMPERA-CHD registry, treatment was predominantly monotherapy (69.3%), this has shifted to favoring combination therapy in the current group (53%). For the first time, the nature, frequency, and treatment of significant comorbidities requiring supportive care and medication are described. CONCLUSIONS Analyzing "real life data" from the international COMPERA-CHD registry, we present a comprehensive overview about current management modalities and treatment concepts in PAH-CHD. There was an trend towards more aggressive treatment strategies and combination therapies. In the future, particular attention must be directed to the "Non-Eisenmenger PAH" group and to patients with complex CHD, including Fontan patients.

Abstract
In adults with congenital heart disease (ACHD), conditions acquired with aging, such as metabolic syndrome, hypertension, diabetes mellitus, and obesity, can negatively influence the original cardiovascular disease. Metabolic syndrome has a higher prevalence in ACHD than in the general population. In contrast, coronary artery disease shows a similar prevalence in adults with acyanotic CHD and the general population, while adults with cyanotic CHD, even after repair, have an even lower incidence of coronary artery disease than the general population/adults with acyanotic CHD. However, even in those with cyanotic CHD, coronary artery disease can develop when they have risk factors such as obesity, dyslipidemia, hypertension, diabetes mellitus, smoking habit, or limited exercise. The prevalence of risk factors for cardiovascular disease is similar between ACHD and the general population, but an increased risk of coronary atherosclerosis has been observed for congenital coronary artery anomalies, dextro-transposition of the great arteries after arterial switch operation, Ross procedure, and coarctation of the aorta. Aortopathy may be an additional risk factor for cardiovascular disease. As ACHD have other abnormalities that may make the heart more vulnerable to both the development of atherosclerosis and adverse cardiovascular sequelae, regular evaluation of their cardiovascular disease risk status is recommended. Metabolic syndrome is more common among ACHD than in the general population, and may therefore increase the future incidence of atherosclerotic coronary artery disease even in ACHD. Thus, ACHD should be screened for metabolic syndrome to eliminate risk factors for atherosclerotic coronary artery disease.

Peripheral microangiopathy in Eisenmenger syndrome: A nailfold video capillaroscopy study. Int J Cardiol 2021; 336:54-59. [PMID: 33741426 DOI: 10.1016/j.ijcard.2021.03.033] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2020] [Revised: 03/08/2021] [Accepted: 03/12/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND Eisenmenger syndrome (ES) comprises a severe phenotype of pulmonary arterial hypertension characterized by angiopathy of the lung circulation. The aim of the present study was to demonstrate the presence of systemic microvascular abnormalities in patients with ES using nailfold video-capillaroscopy (NVC) and to identify potential correlations of nailfold capillaroscopic characteristics with non-invasive markers of systemic organ function. METHODS Α cross-sectional NVC study was performed in 17 consecutive patients with ES and 17 healthy controls matched for age and sex. NVC quantitative (capillary density, capillary dimensions, haemorrhages, thrombi, shape abnormalities) and qualitative (normal, non-specific or scleroderma pattern) parameters were evaluated. RESULTS Patients with ES [median age 40 (18-65) years, 11 women] presented reduced capillary density [8.8 (7.2-10.2) loops/mm vs. 9.9 (8.3-10.9) loops/mm, p = .004] and increased loop width [15.9 (10.3-21.7) μm vs. 12.3 (7.6-15.2) μm, p < .001], while they had significantly more abnormal capillaries than healthy controls [2.5 (0.9-5.4) abnormal loops/mm vs. 1.0 (0.0-1.7) abnormal loops/mm, p < .001]. NVC shape abnormalities in ES were positively correlated with NT-proBNP (r = 0.52, p = .03) and were negatively associated with estimated glomerular filtration rate (r = -0.60, p = .02). Additionally, capillary loop diameter was positively correlated with increased haemoglobin levels (r = 0.55, p = .03) and negatively correlated with reduced peripheral oxygen saturation (r = - 0.56, p = .02). CONCLUSIONS This study supports the hypothesis of peripheral microvascular involvement in ES parallel to pulmonary microangiopathy detected by NVC. Further longitudinal studies are needed to confirm our preliminary results.

Thrombocytopaenia in cyanotic CHD. Cardiol Young 2021; 31:429-434.

Abstract
INTRODUCTION Thrombocytopaenia is common in adults with cyanotic heart disease. Our aim was to explore potential mechanisms for thrombocytopaenia in these vulnerable patients. METHODS Adults with cyanotic heart defects were identified from our clinical database. Haemoglobin levels, platelet counts, and resting oxygen saturations were determined at baseline and during follow-up. Associations between patient characteristics and cardiac physiology with these parameters at baseline and during follow-up were analysed using regression models. Survival estimates were determined by the Kaplan-Meier method. RESULTS We included 79 patients (mean age 32.2 ± 12.4, 48 (61%) Eisenmenger syndrome, 20 (25%) Down syndrome). Mean oxygen saturation was 84.1 ± 5.9%; 38 (48%) had thrombocytopaenia. There was a strong inverse correlation between platelet count and haemoglobin level (R = -0.655, R2 = 0.429, p < 0.0001) and a weaker but significant positive correlation between platelet count and oxygen saturation (R = 0.345, R2 = 0.119, p = 0.002). There was a significant inverse correlation between decrease in platelet count and increase in haemoglobin level during follow-up (R = -0.401, R2 = 0.161, p = 0.001) but not to changes in oxygen saturation (R = 0.043, R2 = 0.002, p = 0.726). Survival estimates were lower for patients with thrombocytopaenia at baseline (log-rank test p < 0.0001). CONCLUSIONS Our findings suggest a direct inverse correlation between platelet counts and haemoglobin levels in adults with cyanotic heart disease. Further studies are required to explore the mechanisms of thrombocytopaenia in cyanotic heart disease and its potential role as an independent marker of risk.

Abstract
BACKGROUND Recent basic studies demonstrate that the lung is a primary organ of platelet biogenesis. However, whether the pathophysiological state of the lung affect the platelets is little known. We aim to investigate the incidence of thrombocytopenia in patients with pulmonary infection (PIN) and risk factors associated with pulmonary thrombocytopenia. METHODS In total, 11,941 patients with pulmonary infection (PIN) were enrolled, and patients with other three infectious diseases were collected as controls. The incidence of thrombocytopenia was compared, and the risk factors associated with thrombocytopenia in PIN patients were investigated by multivariate analysis. To explore the mechanism of thrombocytopenia, hypoxic model was constructed. Blood platelet counts from the angular vein (PLTs), left ventricle (PLTpost) and right ventricle (PLTpre) were determined. Megakaryocytes identified by anti-CD41 antibody were detected through flow cytometry and immunofluorescence. RESULTS The incidence of thrombocytopenia in PIN was higher than that in other three infectious diseases (9.8% vs. 6.4% ~ 5.0%, P < 0.001). Low arterial oxygen partial pressure (PaO2) was an important risk factor for thrombocytopenia (OR = 0.88; P < 0.001). In a hypoxic mouse model, PLTs decreased (518.38 ± 127.92 vs 840.75 ± 77.30, P < 0.05), which showed that low PaO2 induced thrombocytopenia. The difference between the PLTpost and PLTpre (∆PLTpost-pre), representing the production of platelets in the lungs, was significantly attenuated in hypoxic mice when compared with normoxic mice (F = 25.47, P < 0.05). Additionally, proportions of CD41-positive megakaryocytes in the lungs, marrow, spleen all decreased in hypoxic mice. CONCLUSION There is a high incidence for thrombocytopenia in PIN patients. Low PaO2-induced thrombocytopenia is associated with impaired generation of platelet in the lungs.

Abstract
The presence of thrombocytopenia in cyanotic congenital heart disease (CCHD) is an uncommon, but well-known condition. We present a patient with pulmonary atresia with ventricular septal defect (PA with VSD) requiring a multi-stage operation. We were unsure whether the patient's hypoxia was the cause of his thrombocytopenia, as the hypoxia was relatively mild. His thrombocytopenia improved following reoxygenation after the Rastelli operation (total correction of PA with VSD). From these findings, we suggest that if a patient with CCHD presents with thrombocytopenia without an obvious cause, hypoxia-induced thrombocytopenia should be considered, regardless of the degree of hypoxia, platelet count, or hematocrit percentage.

Abstract
OBJECTIVES Few studies have investigated the Multiplate platelet function analyzer in pediatrics. The authors evaluated Multiplate combined with Rotem in terms of guiding platelet transfusion after pediatric cardiac surgery with cardiopulmonary bypass (CPB). The authors further compared coagulation parameters between cyanotic and acyanotic patients. DESIGN Subgroup analysis of a randomized clinical trial. SETTING Tertiary hospital. PARTICIPANTS Patients weighing between seven and 15 kg. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Rotem and Multiplate tests were performed (1) after anesthesia induction, (2) upon CPB separation, and (3) upon intensive care unit arrival. Among a total of 59 subjects, 9 patients required platelet transfusion. In multivariate linear regression, analysis EXTEM maximum clot firmness upon CPB separation was associated with the volume of transfused platelets (regression coefficient = -0.348 [95% confidence interval -1.006 to -0.028]; p = 0.039). No such association was found for the Multiplate test. Acyanotic and cyanotic heart disease were present in 32 and 27 children, respectively. There were no significant differences between these two groups in terms of platelet count and function. Postoperative blood loss was significantly higher in the cyanotic group compared with the acyanotic arm (p = 0.015; difference [95% confidence interval -2.40 {-4.20 to -0.60}]). There were no differences between groups regarding transfusion of allogeneic blood products. CONCLUSIONS This study showed that Rotem, but not Multiplate results, were associated with platelet transfusion in pediatric cardiac surgery with no intake of platelet inhibitors. The usefulness of combining these tests in platelet transfusion decision-making needs to be evaluated in larger populations.

Abstract
PURPOSE Adults with congenital heart disease (ACHD) are a rapidly growing population with ever-increasing complexity, and intensive care unit (ICU) management is often necessary. This review summarizes common cardiovascular and non-cardiovascular complications in ACHD and provides a framework for ICU care. RECENT FINDINGS Heart failure is the leading cause of hospitalization and mortality in ACHD. Varied anatomy and repairs, as well as differing physiological complications, limit generalized application of management algorithms. Recent studies suggest that earlier mechanical support in advanced cases is feasible and potentially helpful. Cardiac arrhythmias are poorly tolerated and often require immediate attention. Other complications requiring intensive care include infections such as endocarditis and COVID-19, pulmonary hypertension, renal failure, hepatic dysfunction, coagulopathy, and stroke. Successful ICU care in ACHD requires a multi-disciplinary approach with careful consideration of anatomy, physiology, and associated comorbidities. Few studies have formally examined ICU management in ACHD and further research is necessary.

Abstract
Immature platelets or reticulated platelets are newly released thrombocytes. They can be identified by their large size and high RNA cytoplasm concentration. Immature platelet fraction (IPF) represents the percentage of immature circulative platelets to the total number of platelets. The development of analytical standardization of this hematological parameter by new automated devices allowed a better exploration of its contribution in a context of thrombocytopenia. In fact, several studies had confirmed its clinical utility to differentiate immune thrombocytopenia from other causes of thrombocytopenia. IPF can also predict platelets recovery after chemotherapy and successful engraftment. In addition, immature platelets have shown utility in other diseases such as coronary artery diseases, bacterial infections and liver diseases. Despite all these advantages, immature platelet fraction can be increased in some cases of thrombocytopenia characterized by platelets hypoproduction. The aim of this review is to present the immature platelet fraction contribution in clinical practice.

Abstract
INTRODUCTION Pulmonary hypertension (PH) is a common complication in patients with congenital heart disease (CHD), aggravating the natural, post-operative, or post-interventional course of the underlying anomaly. The various CHDs differ substantially in characteristics, functionality, and clinical outcomes among each other and compared with other diseases with pulmonary hypertension. OBJECTIVE To describe current management strategies and outcomes for adults with PH in relation to different types of CHD based on real-world data. METHODS AND RESULTS COMPERA (Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension) is a prospective, international PH registry comprising, at the time of data analysis, >8200 patients with various forms of PH. Here, we analyzed a subgroup of 680 patients with PH due to CHD, who were included between 2007 and 2018 in 49 specialized centers for PH and/or CHD located in 11 European countries. At enrollment, the patients´ median age was 44 years (67% female), and patients had either pre-tricuspid shunts, post-tricuspid shunts, complex CHD, congenital left heart or aortic disease, or miscellaneous other types of CHD. Upon inclusion, targeted therapies for pulmonary arterial hypertension (PAH) included endothelin receptor antagonists, PDE-5 inhibitors, prostacyclin analogues, and soluble guanylate cyclase stimulators. Eighty patients with Eisenmenger syndrome were treatment-naïve. While at inclusion the primary PAH treatment for the cohort was monotherapy (70% of patients), with 30% of the patients on combination therapy, after a median observation time of 45.3 months, the number of patients on combination therapy had increased significantly, to 50%. The use of oral anticoagulants or antiplatelets was dependent on the underlying diagnosis or comorbidities. In the entire COMPERA-CHD cohort, after follow-up and receiving targeted PAH therapy (n = 511), 91 patients died over the course of a 5-year follow up. The 5-year Kaplan-Meier survival estimate for CHD associated PH was significantly better than that for idiopathic PAH (76% vs. 54%; p < 0.001). Within the CHD associated PH group, survival estimates differed particularly depending on the underlying diagnosis and treatment status. CONCLUSIONS In COMPERA-CHD, the overall survival of patients with CHD associated PH was dependent on the underlying diagnosis and treatment status, but was significantly better as than that for idiopathic PAH. Nevertheless, overall survival of patients with PAH due to CHD was still markedly reduced compared with survival of patients with other types of CHD, despite an increasing number of patients on PAH-targeted combination therapy.

Abstract
Megakaryocytes are normal cellular components of the blood returning to the heart and entering the lungs, and historical data has pointed to a role of the lungs in platelet production. Recent studies using intravital microscopy have demonstrated that platelet release occurs in the lung from bone marrow megakaryocytes that embolize into the lung circulation.

Abstract
A 65-year-old woman presented to the emergency department with an acute onset of left-sided hemiparesis and slurred speech for 6 hours. Physical examination was notable for clubbing and peripheral cyanosis. Brain MRI showed an acute infarct involving the right gangliocapsular region. Investigations showed an elevated haemoglobin level, a haematocrit level of >65% and thrombocytopaenia. Transthoracic echocardiography revealed tricuspid atresia, ventricular septal defect and atrial septal defect. A diagnosis of cyanotic congenital heart disease was made. Studies have indicated an association between raised haematocrit and vascular occlusive episodes in patients with polycythaemia vera. However, a relationship between raised haematocrit due to polycythaemia secondary to complex congenital heart disease and vascular thrombosis has not been reported. The improvement of neurological deficits in our patient coincided with a decline in haematocrit. The objective of this report was to highlight an association between elevated haematocrit and ischaemic stroke in patients with secondary polycythaemia due to complex congenital heart disease.

Abstract
A 3-year-old boy with tetralogy of Fallot and recurrent cyanotic spells was found to have severe thrombocytopenia with platelet counts in the range of 11–30,000/mm3. There was a hesitation to operate in view of the high bleeding risk due to profound thrombocytopenia. However, the total correction was done after excluding other causes of thrombocytopenia. His platelet count dramatically improved after the operation.

Abstract
BACKGROUND Eisenmenger syndrome is a rare sequela of uncorrected congenital heart disease complicated by pulmonary hypertension, from which reversal of the pathologic left-to-right cardiovascular shunt and cyanosis follow. Right-to-left shunting can lead to paradoxical cerebral emboli-increasing the risk of spontaneous or iatrogenic stroke and cerebral abscess. CASE DESCRIPTION A 38-year-old man presented with new focal seizures due to a brain abscess. Ventricular septal defect and pulmonary hypertension were identified. Despite dexamethasone and broad-spectrum antibiotics, he developed hemiparesis and altered mental status and required emergent stereotactic abscess drainage. Despite the anesthetic hazards of Eisenmenger syndrome, the procedure was successful and the patient recovered completely. CONCLUSIONS Noncardiac perioperative mortality in Eisenmenger syndrome is historically reported up to 19%, and risks are further increased with prolonged case duration or hypotension, mandating vigilant attention to volume status. Correspondingly, shorter- or lower-risk procedures such as stereotactic drainage are recommended. Procedures should be performed only at centers with expertise in management of Eisenmenger syndrome and cardiac-specialized anesthesiologists whenever possible. Although a conservative approach with early, aggressive medical management is preferred, operative intervention may be required in the setting of progressive deterioration and excellent postoperative outcomes are achievable.

Abstract
In adult congenital heart disease (ACHD), residua and sequellae after initial repair develop late complications such as cardiac failure, arrhythmias, thrombosis, aortopathy, pulmonary hypertension and others. Acquired lesions with aging such as hypertension, diabetes mellitus, obesity can be negative influence on original cardiovascular disease (CVD). Also, atherosclerosis may pose an additional health problem to ACHD when they grow older and reach the age at which atherosclerosis becomes clinically relevant. In spite of the theoretical risk of atherosclerosis in ACHD due to above mentioned factors, cyanotic ACHDs even after repair are noted to have minimal incidence of coronary artery disease (CAD). Acyanotic ACHD has similar prevalence of CAD as the general population. However, even in cyanotic ACHD, CAD can develop when they have several risk factors for CAD. The prevalence of risk factor is similar between ACHD and the general population. Risk of premature atherosclerotic CVD in ACHD is based, 3 principal mechanisms: lesions with coronary artery abnormalities, obstructive lesions of left ventricle and aorta such as coarctation of the aorta and aortopathy. Coronary artery abnormalities are directly affected or altered surgically, such as arterial switch in transposition patients, may confer greater risk for premature atherosclerotic CAD. Metabolic syndrome is more common among ACHD than in the general population, and possibly increases the incidence of atherosclerotic CAD even in ACHD in future. Thus, ACHD should be screened for metabolic syndrome and eliminating risk factors for atherosclerotic CAD.

Abstract
Adults with cyanotic congenital heart diseases (CCHD) have a higher risk for bleeding, but also for thrombosis. Rotational thromboelastometry (RT), using tissue factor (EXTEM), a contact activator (INTEM) or cytochalasin (FIBTEM), assesses coagulation by determining the time to initiation of clotting (CT) and clot firmness (MCF) including platelet-fibrin-interaction. The aim of this study was to evaluate RT and whole blood impedance aggregometry (IA) in CCHD compared with a control group without chronic cyanosis (NCCHD). These were used to establish normal reference ranges. We prospectively included 124 patients (76 CCHD, 48 NCCHD). Mean oxygen saturation in CCHD was 81.5%, and 98% in NCCHD (p <0.001). Fifty-five CCHD and 1 NCCHD had pulmonary hypertension. Eisenmenger syndrome was present in 39 CCHD (51.3%). Hemoglobin, hematocrit, and reticulocyte levels were significantly higher in CCHD, and they also showed more thrombocytopenia. Platelet aggregation was under normal range in 89.5% of CCHD after triggering with ADP, in 85.5% after triggering with arachidonic acid (ASPI) and in 73.7% after TRAP-6. RT showed significantly longer clotting times and reduced clot firmness in both EXTEM and INTEM tests. FIBTEM-MCF was also significantly reduced. Moderate inverse correlation was found between platelet count and erythrocytes (r = -0.608, p <0.001). Significant correlations were found between platelet number and RT-parameters as well as with all IA parameters. In conclusion, according to RT and IA, CCHD present hypocoagulable disorders. No signs of hypercoagulability were found.

Abstract
Patients with Eisenmenger syndrome (ES) have a higher mortality rate than patients with simple congenital heart disease (CHD). To determine factors associated with death in the era of advanced pulmonary vasodilator treatment, we analyzed the characteristics of adult ES patients depending on underlying CHD. Simple septal defects and patent ductus arteriosus were classified as simple CHD, and other conditions were classified as complex CHD. Sixty-seven adult ES patients (50.7% women) were reviewed retrospectively. CHD was diagnosed at a median of 10.0 years of age and ES was diagnosed at 18.6 years. Thirteen patients (19.4%) died; the median age was 38.6 years (IQR 32.2-47.8). In a multivariate analysis, patients with SpO2 < 85% had a higher mortality rate than others [hazard ratio (HR) 9.7; 95% confidence interval (CI) 1.002-95.2, p = 0.05]. In simple CHD patients, those with a low platelet count (< 100 × 109/L) or low SpO2 (< 85%) were at a higher risk of death than those without (HR 16.32, 95% CI 1.25-2266.31, p = 0.032; and HR 38.91, 95% CI 3.44-5219.41, p = 0.001, respectively). Advanced pulmonary vasodilators were used more in survivors than in non-survivors (48.1% vs. 15.4%, p = 0.032). Low SpO2 and platelet count were related to mortality in adult ES, especially in those with simple CHD. Therefore, careful attention should be paid to the care of adult ES patients with this tendency; active pulmonary vasodilator treatment should be considered.

Abstract
The presentation of coronary artery disease in a patient with Eisenmenger syndrome (ES) is relatively rare. Cardiogenic shock due to coronary artery dissection during percutaneous coronary intervention (PCI) can be more critical in these patients. Here, we report a case of successful PCI under mechanical circulation support in a patient with ES who experienced potentially fatal right coronary artery dissection. This case emphasizes that use of extracorporeal membrane oxygenation (ECMO) can lead to successful management of critical complication during PCI, and that the immediate decision to apply of ECMO is important in ES patients who face impending cardiogenic shock with acute heart failure.

Abstract
In the summer of 2016, delegates from the German Respiratory Society (DGP), the German Society of Cardiology (DGK) and the German Society of Pediatric Cardiology (DGPK) met in Cologne, Germany, to define consensus-based practice recommendations for the management of patients with pulmonary hypertension (PH). These recommendations were built on the 2015 European Pulmonary Hypertension guidelines, aiming at their practical implementation, considering country-specific issues, and including new evidence, where available. To this end, a number of working groups was initiated, one of which was specifically dedicated to PH in adults associated with congenital heart disease (CHD). As such patients are often complex and require special attention, and the general PAH treatment algorithm in the ESC/ERS guidelines appears too unspecific for CHD, the working group proposes an analogous algorithm for the management of PH-CHD which takes the special features of this patient group into consideration, and includes general measures, supportive therapy, targeted PAH drug therapy as well as interventional and surgical procedures. The detailed results and recommendations of the working group on PH in adults with CHD, which were last updated in the spring of 2018, are summarized in this article.

Abstract
Adult congenital heart disease (ACHD) is a constantly expanding population with challenging issues. Initial medical and surgical treatments are seldom curative, and the majority of patients still experience late sequelae and complications, especially thromboembolic events. These common and potentially life-threating adverse events are probably dramatically underdiagnosed. Better identification and understanding of thromboembolic risk factors are essential to prevent long-term related morbidities. In addition to specific situations associated with a high risk of thromboembolic events (Fontan circulation, cyanotic congenital heart disease), atrial arrhythmia has been recognized as an important risk factor for thromboembolic events in ACHD. Unlike in patients without ACHD, thromboembolic risk stratification scores, such as the CHA2DS2-VASc score, may not be applicable in ACHD. Overall, after a review of the scientific data published so far, it is clear that the complexity of the underlying congenital heart disease represents a major risk factor for thromboembolic events. As a consequence, prophylactic anticoagulation is indicated in patients with complex congenital heart disease and atrial arrhythmia, regardless of the other risk factors, as opposed to simple heart defects. The landscape of ACHD is an ongoing evolving process, and specific thromboembolic risk scores are needed, especially in the setting of simple heart defects; these should be coupled with specific trials or long-term follow-up of multicentre cohorts.

Abstract
BACKGROUND We examined the association of preoperative cell count abnormalities, which have been shown to be associated with outcomes in adult cardiac patients, with morbidity and mortality after operation for congenital heart disease (CHD) in children. METHODS We performed a retrospective cohort study on 4,865 children undergoing cardiac operation from 2004 to 2014. Our exposures of interest were presence of preoperative lymphopenia (lymphocyte count ≤ 3,000 cells/μL), thrombocytopenia (platelet count < 150 × 103/μL), and neutrophilia (neutrophil count ≥ 7,000 cells/μL). Our outcomes of interest were mortality status, postoperative length of stay (LOS), and occurrence of postoperative complications. We performed logistic and linear regressions to determine the associations of preoperative cell counts with mortality, LOS, and complications, adjusting for age, sex, race or ethnicity, presence of a genetic syndrome, and Society of Thoracic Surgeons and European Association for Cardio-Thoracic Surgery Congenital Heart Surgery Mortality category. RESULTS Overall mortality was 2.8%, median LOS was 6 days, and 7.6% of patients had postoperative complications. Lymphopenia was associated with increased odds of postoperative mortality (odds ratio 1.67, 95% confidence interval: 1.15 to 2.43, p = 0.007). Lymphopenia, thrombocytopenia, and neutrophilia were all associated with longer postoperative LOS. Lymphopenia and thrombocytopenia were associated with increased occurrence of postoperative sepsis, and neutrophilia was associated with need for postoperative mechanical circulatory support. CONCLUSIONS In children undergoing CHD operation, preoperative lymphopenia is associated with increased in-hospital mortality postoperatively. Preoperative lymphopenia, neutrophilia, and thrombocytopenia are associated with longer postoperative LOS and with development of postoperative complications. Preoperative cell counts may serve as important prognostic markers in preoperative planning for patients with CHD.

Abstract
BackgroundChildren with cyanotic heart disease develop secondary erythrocytosis and thrombocytopenia via unknown mechanisms. Mature erythrocyte microRNAs may reflect clinical pathologies and cell differentiation processes pre-enucleation. This study evaluated erythrocyte microRNAs in children with cyanotic heart disease.MethodsErythrocyte microRNAs from children with cyanotic and acyanotic heart disease and without cardiac disease were quantified with Ion PGM System (n=10 per group). Differential expression was confirmed by quantitative PCR (qPCR; n=20 per group).ResultsMir-486-3p, mir-486-5p, and mir-155-5p increased in patients with cyanotic heart disease compared with those without heart disease: fold differences (95% confidence interval): mir-486-3p: 1.92 (1.14-3.23), P=0.011; mir-486-5p: 2.27 (1.41-3.65), P<0.001; and mir-155-5p: 1.44 (1.03-2.03), P=0.028. Mir-486-5p was increased, and let-7e-5p and mir-1260a were decreased in patients with acyanotic heart disease compared with those without heart disease: mir-486-5p: 1.66 (1.03-2.66), P=0.035; let-7e-5p: 0.66 (0.44-0.99), P=0.049; and mir-1260a: 0.53 (0.29-0.99), P=0.045.ConclusionSeveral microRNA levels changed in children with cyanotic and acyanotic heart disease. Mir-486-3p and -5p are associated with hematopoietic differentiation. Mir-486-3p regulates the erythroid vs. megakaryocyte lineage fate decision. Mir-155 is a hypoxia-inducible microRNA, whose overexpression inhibits megakaryocyte differentiation. Erythrocyte microRNA expression changes may contribute to erythrocytosis and thrombocytopenia in children with cyanotic heart disease.

Abstract
BACKGROUND Cyanotic nephropathy (CN), seen in 30-50% of patients with congenital cyanotic heart disease (CCHD), affects both tubular and glomerular function, resulting in proteinuria and azotemia. Microalbuminuria is an early marker for glomerular damage and an independent predictor of progressive renal disease. METHODS A cross-sectional study was conducted. A total of 116 patients aged 1 month to 15 years with CCHD at Chiang Mai University Hospital between 2015 and 2016 were assessed and 94 patients were enrolled. To determine the prevalence and associated factors of significant albuminuria in CCHD patients, baseline characteristics, oxygen saturation, surgery, hemoglobin (Hb), hematocrit (Hct), spot urine albumin, urine protein, and creatinine were obtained. Binary logistic-regression modeling was used to identify associated factors. RESULTS Prevalence of CN in children with CCHD was 58.51% and 92.55% according to albuminuria and proteinuria staging respectively. Prevalence of significant proteinuria, significant albuminuria, and decreased GFR was 88.30%, 41.49% and 31.91% respectively. Participants with significant albuminuria had fewer previous surgeries (p = 0.05), a longer waiting time for surgery (p = 0.02), enalapril usage (p = 0.04), pulmonary hypertension (p = 0.03), higher Hct z-score (p = 0.03) and lower platelet count (p = 0.001) compared with those without significant albuminuria. Using multivariate logistic regression analysis, waiting duration for surgery (p = 0.04), Hct >40% (p = 0.02), and platelet count <290,000/mm3 (p = 0.04) were predictive of microalbuminuria. CONCLUSIONS Cyanotic nephropathy can be detected in the first decade of life with the presentation of microalbuminuria. High Hct level and low platelet count were identified as a predictor of microalbuminuria, whereas early cardiac surgery decreased the risk of developing significant albuminuria.

Abstract
BACKGROUND Immune abnormalities are common in Fontan patients with protein-losing enteropathy. Limited data exist on immune function of other patients with single ventricle circulation. METHODS This prospective cohort study evaluated immunologic characteristics of children with single ventricle circulation from neonatal age up to early post-Fontan period. RESULTS Low leukocyte counts were observed in half of the patients prior to bidirectional Glenn and Fontan surgery. Total lymphocyte counts were below normal range in 36% to 63% of patients across all groups except patients following Fontan procedure who had normal counts. Typical lymphocyte subpopulation patterns were (1) high counts of total and helper T lymphocytes (CD3+ and CD4+ cells), low B lymphocytes (CD19+ cells), and increased CD4/CD8 ratio in neonates and (2) low T lymphocytes (CD3+, CD4+, CD8+ cells) with high natural killer cells (CD16+) and B lymphocytes (CD19+ cells) in other groups. Low preoperative total lymphocyte counts were associated with longer intensive care unit stay in patients after bidirectional Glenn and Fontan procedure ( P = .03 and P = .01, respectively) and low leukocyte counts with higher incidence of pleural effusions and chylothorax after Fontan procedure ( P = .005 and P = .002, respectively). CONCLUSIONS Single ventricle patients display several immunological abnormalities. Beyond the neonatal age, an immune pattern includes CD3+, CD4+, CD8+ lymphopenia, and CD16+ and CD19+ lymphocytosis. B-cell lymphocytosis compensates T-cell lymphopenia, producing normal total lymphocyte counts in patients early after Fontan surgery. Low preoperative total lymphocyte counts may be associated with longer postoperative intensive care unit stay in patients with bidirectional Glenn and Fontan procedure and leukopenia with pleural effusions in Fontan patients.

Abstract
Life expectancy and quality of life for those born with congenital heart disease (CHD) have greatly improved over the past 3 decades. While representing a great advance for these patients, who have been able to move from childhood to successful adult lives in increasing numbers, this development has resulted in an epidemiological shift and a generation of patients who are at risk of developing chronic multisystem disease in adulthood. Noncardiac complications significantly contribute to the morbidity and mortality of adults with CHD. Reduced survival has been documented in patients with CHD with renal dysfunction, restrictive lung disease, anemia, and cirrhosis. Furthermore, as this population ages, atherosclerotic cardiovascular disease and its risk factors are becoming increasingly prevalent. Disorders of psychosocial and cognitive development are key factors affecting the quality of life of these individuals. It is incumbent on physicians who care for patients with CHD to be mindful of the effects that disease of organs other than the heart may have on the well-being of adults with CHD. Further research is needed to understand how these noncardiac complications may affect the long-term outcome in these patients and what modifiable factors can be targeted for preventive intervention.

Abstract
OBJECTIVES Although a significant proportion of patients with cyanotic congenital heart disease are thrombocytopaenic, its prevalence and clinical significance in adults with Eisenmenger syndrome (ES) is not well studied. Accordingly, we examined the relationship of thrombocytopaenia and mean platelet volume (MPV) to bleeding or thrombotic complications and survival in a contemporary cohort of patients with ES, including patients with Down syndrome. METHODS Demographics, laboratory and clinical data were analysed from 226 patients with ES under active follow-up over 11 years. RESULTS Age at baseline was 34.6±11.4 years and 34.1% were men. Mean platelet count and MPV were 152.6±73.3×109/L and 9.6±1.2 fL, respectively. A strong inverse correlation was found between platelet count and haemoglobin concentration and MPV. During the study, there were 39 deaths, and 21 thrombotic and 43 bleeding events. On univariate Cox regression analysis, patients with a platelet count <100×109/L had a twofold increased mortality (HR 2.10, 95% CI 1.10 to 4.01, p=0.024). Platelet count was not associated with an increased risk of thrombosis. However, there was a threefold increased thrombotic risk with MPV >9.5 fL (HR 3.50, 95% CI 1.28 to 9.54, p=0.015). Patients with either severe secondary erythrocytosis (>220g/L) or anaemia (<130g/L) were at higher risk of thrombotic events (HR 3.93, 95% CI 1.60 to 9.67, p=0.003; and HR 4.75, 95% CI 1.03 to 21.84, p=0.045, respectively). CONCLUSIONS Thrombocytopaenia significantly increased the risk of mortality in ES. Furthermore, raised MPV, severe secondary erythrocytosis and anaemia, but not platelet count, were associated with an increased risk of thrombotic events in our adult cohort.
