RESUMEN
Multisystem inflammatory syndrome in children (MIS-C) shares several clinical and immunological features with Kawasaki Disease (KD) and pediatric hyperinflammation, but the immuno-phenotypic overlap among these clinical mimics is still incompletely understood. Here we analyzed serum samples from treatment-naïve patients with MIS-C (n = 31) and KD (n = 11), pediatric hyperinflammation (n = 13) and healthy controls (HC, n = 10) by proximity extension assay (PEA) to profile 184 blood biomarkers. Collectively, immunophenotypic overlap between MIS-C and hyperinflammation exceeds overlap with KD. Overexpression of IL-17A in MIS-C and KD could best separate these conditions from hyperinflammatory conditions, while those were hallmarked by overabundance of adenosin deaminase and IL-18. Depletion in serum TNF-related subfamily member 9 (TNFRSF9) and apoptosis inducing ligand (TRAIL) linked with cardiovascular manifestations and myocarditis in MIS-C. Altogether, our analysis highlights important differences in molecular marker signatures also across different MIS-C and KD cohorts and suggests several previously unidentified molecular associations in context of cardiovascular inflammation.

OBJECTIVE: Studies suggest that men who undergo assisted reproductive technologies (ART) may have a higher risk of cardiovascular disease; however, limited data on this matter is available. This observational pilot study aimed to investigate the overall vascular health of fathers with history of intracytoplasmic sperm injection (ICSI) compared to fathers whose partners conceived spontaneously. METHODS: Diet quality, physical activity, sedentary behavior as well as overall vascular function including the assessment of pulse wave analysis, intima-media thickness (cIMT), arterial stiffness of the common carotid artery (CCA) and blood lipids, were evaluated. RESULTS: A total of 34 fathers with history of ICSI and 29 controls (48.49 [46.32 - 57.09] years vs. 47.19 [40.62 - 55.18] years, p = 0.061) were included. After adjusting for age, no significantly increased cardiovascular risk was detected regarding vascular function. CONCLUSIONS: The results suggest an unaltered cardiovascular risk profile in fathers with history of ICSI. In the future, prospective multicenter studies are required to validate these preliminary results.

INTRODUCTION: Hypercholesterolemia is a risk factor for premature arteriosclerosis. Inflammation and oxidative stress are thought to contribute to endothelial dysfunction preceding vasculopathy. We investigated the association between inflammation, glycocalyx biomarkers, endothelial function and vascular parameters in children with hypercholesterolemia. METHODS: In 22 patients (LDL-cholesterol > 130 mg/dl; median age [IQR]: 13 [2.3] years) and 22 controls (13 [2.5] years) tumor necrosis factor-alpha (TNF-α), oxidized cholesterol (oxLDL), and glycocalyx biomarkers (Syndecan-1, Hyaluronan) were measured using immunoassays. Endothelial function was assessed by peripheral arterial tonometry, sublingual glycocalyx and microcirculation by videomicroscopy and carotid intima media thickness by ultrasound. RESULTS: OxLDL was significantly higher in patients (78.9 [38.2] vs. 50.3 [16.6] U/l, p=0.002), whereas all other experimental parameters were comparable between groups. Multivariate analysis revealed a significant association of Syndecan-1 with TNF-α (ß=0.75, p<0.001) and with hypercholesterolemia (ß=0.31, p=0.030). The interaction term combining TNF-α and hypercholesterolemia showed a significant effect (p=0.034). Sex was an independent predictor of endothelial function. CONCLUSION: The combined effect of hypercholesterolemia and inflammation on glycocalyx perturbation and the impact of sex in the premature development of arteriosclerosis deserve further evaluation. Therapeutic approaches tackling low grade systemic inflammation-may offer potential to prevent or delay progression of CVD and cardiovascular complications. .
RESUMEN
Increased aortic stiffness predisposes cardiac afterload and influences cardiac function. Congenital heart diseases involving aortic arch malformation and extended cardiovascular surgery, i.e. univentricular heart diseases, can lead to increased aortic stiffness. This study aimed to investigate whether Fontan patients (FO) have increased aortic stiffness within distinct aortic segments, and whether these parameters relate to Fontan-specific haemodynamics. In a prospective case-control study, 20 FO and 49 heart-transplanted control subjects with biventricular circulation underwent invasive cardiac catheterisation. We invasively measured pulse wave velocity (PWV) in the ascending aorta and along the entire aorta. Haemodynamic parameters, including end-diastolic pressure, pulmonary artery pressure, the cardiac index and systemic vascular resistance index were also assessed. FO exhibited significantly higher ascending aorta PWV (aPWV) than controls (FO: 7.2 ± 2.4 m/s|Controls: 4.9 ± 0.7 m/s, p < 0.001) and compared to the inner group central aorta PWV (cPWV; FO: 5.5 ± 1.2 m/s|Controls: 5.3 ± 1.0 m/s). Multivariate analysis confirmed this aPWV elevation in FO even after adjusting for age and BMI. aPWV and cPWV were almost identical within the control group. Correlation analyses revealed associations between cPWV and blood pressure in controls, while correlations were less apparent in FO. We detected no significant association between the aPWV and other haemodynamic parameters in any of our groups. FO exhibit increased aPWV, indicating specific vascular stiffness in the ascending aorta, while their overall aortic stiffness remains comparable to controls. Further research is needed to understand the implications of these findings on Fontan circulation and long-term cardiovascular health. CENTRAL MESSAGE: Fontan patients show increased aortic arch pulse wave velocity, suggesting specific vascular stiffness. PERSPECTIVE STATEMENT: Our study offers rare insights into pulse wave velocity in Fontan patients, highlighting increased arterial stiffness in the aortic arch. Vascular stiffness was particularly increased in the area of surgical reconstruction. This indicates the need for further research on vascular stiffness in Fontan circulation to understand its impact on cardiovascular health.

RESUMEN
BACKGROUND: Energy drinks (EDs) are popular beverages among minors. To date, clinical studies investigating ED-induced effects on the pediatric cardiovascular system are sparse. This study aimed to investigate the effects of a single, bodyweight-adjusted ED dosage on 24-h ambulatory blood pressure monitoring (ABPM) in healthy children and adolescents. METHODS: This study was a randomized, single-blind, placebo-controlled, crossover clinical trial. Study participants received a single, bodyweight-adjusted ED amount or a placebo drink on 2 consecutive days at similar morning hours. Twenty-four-hour ABPM was assessed via an automated oscillometric blood pressure device after beverage consumption on both study days. RESULTS: A total of 17 healthy children and teenagers (13.90 (12.29-17.89) years) were included in the final analysis. The ED consumption led, compared to the placebo intake, to a significantly higher 24-h systolic (115.90 (110.22-118.04) vs. 110.64 (108.09-115.45) mmHg, p = 0.013) and diastolic blood pressure (66.08 (64.20-68.32) vs. 62.63 (61.40-66.46) mmHg, p = 0.005). CONCLUSIONS: The single, bodyweight-adjusted ED consumption is linked with a significantly higher systolic as well as diastolic 24-h blood pressure in healthy children and adolescents. Minors, particularly those with an increased cardiovascular morbidity, should be discouraged from drinking EDs. IMPACT: Energy drinks (EDs) are consumed by many children and teenagers. While adverse cardiovascular events after ED consumption were reported in the literature, the effects of these beverages on the pediatric 24-h blood pressure profile have not been systematically evaluated yet. In our manuscript, we demonstrate for the first time that acute ED consumption is associated with a significantly higher 24-h systolic blood pressure and diastolic blood pressure in healthy minors.

Tricuspid annular plane systolic excursion (TAPSE) is important in the noninvasive echocardiographic assessment of right heart function. This retrospective observational study shows correlations of TAPSE with invasive right heart catheterization parameters after pediatric heart transplantation (HTx). The study included patients after pediatric HTx with cardiac catheterizations in 2018/2019 and measurement of TAPSE (n = 52 patients with 57 examinations; 50.9% adults, 52.6% female, median age: 18.54 years). TAPSE was compared with normal values. Stepwise, linear and multiple regression were used to show influencing variables on TAPSE. Mean TAPSE z-score was -3.48 (SD: 2.25) and 68.4% of HTx-recipients showed abnormally reduced TAPSE (z-score â2) compared to normal values. Multiple regression (p-value <0.001; corrected R2 = 0.338) showed significant correlations of time since HTx (p-value <0.001) and mPAP (p-value: 0.008) with TAPSE z-scores. Divided into subgroups (time since HTx <10 and ≥10 years), TAPSE and mPAP correlated only ≥10 years after HTx (p-value = 0.002). This study provides data of TAPSE even ≥10 years after pediatric HTx. Most patients showed a decreased TAPSE early after HTx, which improved over time. TAPSE z-scores correlated significantly with time since HTx and mPAP, especially ≥10 years post-HTx. Therefore, TAPSE must be used carefully in the early follow-up.

AIMS: Kawasaki disease (KD) is an acute systemic vasculitis with possible long-term impact of general cardio-vascular health. An endothelial glycocalyx disorder during the disease's acute phase might predispose to long-term vascular anomalies leading to endothelial dysfunction and atherosclerosis. To investigate any association between increased cardiovascular risk and endothelial glycocalyx, we assessed circulating glycocalyx components in patients with a KD history, and analysed their association with acute-phase clinical features and more importantly, with patients' current cardiovascular risk factors. METHODS: This prospective observational cohort study included 51 subjects: 31 patients with a history of KD, and 20 healthy subjects matched for age and sex. We analysed serum syndecan-1 and hyaluronan via ELISA. We assessed features reported during the acute phase of KD such as blood counts, C-reactive protein (CRP) levels and coronary artery aneurysms (CAA), and their current blood pressure and lipid markers in relation to measured glycocalyx components. RESULTS: Our multivariate analysis revealed that hyaluronan and syndecan-1 levels were not associated with KD. However, the latter exhibited a significant association with acute-phase blood count alterations in patients with KD. Furthermore, significant interactions of hyaluronan and syndecan-1 with certain cardiovascular risk factors like blood lipids and blood pressure were only present in KD patients. CONCLUSION: Vasculitis during KD's acute phase might predispose to a long-term endothelial glycocalyx alteration, influenced by other factors having a vascular impact such as blood pressure and circulating lipids.

Key aspects of the medical management of Kawasaki disease (KD) are not yet supported by a high evidence level, thus making room for individual recommendations. We performed a structured comparison of existing international KD guidelines to analyze potential differences in the implementation of evidence-based KD recommendations regarding diagnosis and therapy. To identify country-specific guidelines, we took a multilateral approach including a comprehensive PubMed literature, online research, and directly contacting national pediatric associations. We then ran a structured guidelines' analysis and evaluated the diagnostic and therapeutic differences in the context of evidence-based medicine. In this structured guideline analysis, we identified nine national and one European guidelines. According to them all, the diagnosis of KD still relies on its clinical presentation with no reliable biomarker recommended. First-line treatment consistently involves only intravenous immunoglobulin (IVIG) therapy. Recommendations in terms of acetylsalicylic acid, corticosteroids, and additional therapeutic options vary considerably. CONCLUSION: According to all guidelines, KD is diagnosed clinically with some variance in defining incomplete KD and being a non-responder to treatment. First-line treatment consistently includes IVIG. Recommendations for additional therapeutic strategies are more heterogeneous. WHAT IS KNOWN: ⢠The diagnosis of KD relies on the clinical presentation, entailing challenges in timely diagnosis. ⢠Other treatment options then IVIG are not supported by a high evidence level, making room for individual recommendations. WHAT IS NEW: ⢠Definition of incomplete KD and being non-responsive to an initial treatment vary to some extent between the national guidelines. ⢠Only IVIG is consistently proposed throughout all guidelines, further therapeutic recommendations vary between the national recommendations.

An increasing number of children are conceived by assisted reproductive technologies (ART). Several studies indicated vascular alterations in ART children. However, limited data is available within the adult ART population. Therefore, this study investigated the overall vascular health of young ART adults in comparison to spontaneously conceived peers. In total, 16 ART subjects and 22 spontaneously conceived peers (22.06 ± 2.21 years vs. 22.00 ± 2.14 years, p = 0.194) were enrolled for the assessment of endothelial function, brachial blood pressure, central blood pressure, pulse wave velocity, carotid intima-media thickness, and blood lipids. No significant differences in vascular function were detected between the in vitro fertilization subgroup (n = 9), the intracytoplasmic sperm injection subgroup (n = 7) and spontaneously conceived peers. This pilot study suggests an unimpaired vascular function in young ART adults. In the future, multi-centric studies with a greater sample size are required to confirm the results of the current study and enable precise cardiovascular risk stratification of the adult ART population.
RESUMEN
Background: Minors are considered the main consumer group of energy drinks (EDs). The aim of this study was to investigate the acute effects of ED consumption on left ventricular (LV) hemodynamics and efficiency in healthy children and teenagers. Methods: This study was a randomized, single-blind, placebo-controlled, crossover clinical trial. Study participants consumed a weight-adjusted amount of an ED or a placebo on two consecutive days. LV hemodynamics and efficiency parameters were evaluated non-invasively by generating LV pressure−volume loops (PVLs) through simultaneous echocardiography and blood pressure measurement. Results: A total of 24 children and teenagers (14.90 ± 2.27 years, 13 male) were included in the present study. Conventional echocardiographic parameters of LV function did not show significant differences between both beverage groups. The non-invasive generation of LV PVLs revealed a significantly lower cardiac efficiency 240 min after the ED consumption compared to the placebo intake (140.72 (133.21−149.73) mmHg vs. 135.60 (124.78−140.33) mmHg, p < 0.01). Conclusions: Acute ED consumption is associated with a significantly lower cardiac efficiency in healthy minors. The generation of non-invasive LV PVLs might be beneficial in the assessment of subtle changes in LV efficiency. Further studies need to investigate the influence of chronic ED consumption on LV function and morphology.

BACKGROUND: Cardiac allograft vasculopathy (CAV) and nephrotoxicity affect long-term survival after heart transplantation (HTX). Studies, mostly conducted in adults, showed a positive effect of everolimus (EVL) on these problems. We describe the effects of conversion of the immunosuppressive therapy to an everolimus including regime on CAV, renal function, and safety in heart transplanted children/adolescents. METHODS: This retrospective single-center study included 36 participants (mean time after HTX 6.3 ± 4.7 years). Descriptive pre/post-comparisons were performed with an observation period partially up to 4 years. Impact on CAV was assessed based on intravascular imaging and Stanford grading. Safety analysis included cytomegalovirus (CMV)-infection and acute rejection. RESULTS: In terms of CAV (9 out of 36 patients) four showed no progression, three an improvement, one a worsening; one new diagnosis. The average CrCl showed a significant improvement 6, 12, and 24 months after conversion regarding all patients (n = 29). There was no acute rejection or CMV-infection. CONCLUSION: Conversion to an EVL-based therapy after pediatric HTX is a safe immunosuppressive regime without increasing risk of acute rejection or CMV-infection. There was some evidence of reduction in progression of CAV and a significant improvement of the renal function.

Reduced adherence after heart transplantation increases the risk for acute rejection. Therefore, the aim of this study was to evaluate the patient's satisfaction with outpatient care and quality of life (QOL) after pediatric and adult heart transplantation. Observational study after pediatric (n = 22) and adult (n = 65) heart transplantation and the parents of the pediatric patients (n = 22) to evaluate the patients' satisfaction with outpatient care and QOL. Established standardized questionnaires were used for patient satisfaction (ZAP survey) and QOL (SF36); the latter was compared with the cohort of the BGS98 survey (BGS98 cohort). ZAP score: excellent results with almost all values >80. QOL: pediatric cohort showed significantly higher values in physical functioning (P = 0.041) and role physical (P = 0.003) but significantly lower values in the sub-scale general health (P = 0.02) compared to adult cohort. In comparison with BGS98 cohort, children showed almost similar results, whereas adult cohort showed worse values in physical and emotional functioning, but higher values regarding general health. The QOL of patients after pediatric heart transplantation is comparable to a standardized reference population in Germany, whereas adult patients show reduced physical and emotional functioning, but better values regarding general health. The patients' satisfaction with the outpatient care is very high.

A percutaneous pulmonary valve-in-valve (PPVIV) implantation in small surgical tissue valves may be limited due to the valve's initial diameter. Fracturing of the valve's integrity by high-pressure balloons may enhance the diameter and facilitate subsequent PPVIV with a large valve. To the best of our knowledge, the Trifecta® valve seemed not to be accessible for fracturing. We report a case of successful 19-mm Trifecta valve fracturing, followed by PPVIV using a 26-mm Edwards SAPIEN 3 valve in pulmonary position. By repetitively using a high-pressure balloon 5 mm larger than the labeled valve size, we were able to fracture the valve's integrity and implant a 26-mm valve thereafter. Therefore, Trifecta valve appears to be suitable for valve ring fracturing and subsequent PPVIV in certain patients.

Elevated von Willebrand factor (vWF):Antigen plasma levels have been observed in conjunction with cardiovascular diseases or vasculitis. The association of Kawasaki disease, a vascular inflammatory disease and vWF:Antigen, vWF:Collagen binding activity, and vWF multimers is unknown. We therefore investigated vWF parameters in 28 patients with acute Kawasaki disease in association with disease activity and coronary artery lesions. VWF:Antigen and vWF:Collagen binding activity were assessed via enzyme-linked immunoassay. The ratio of both (vWF:Collagen binding activity and VWF:Antigen) was calculated and vWF multimeric structure analysis performed. We analyzed the association between vWF parameters and our clinical data focusing on coronary artery outcome. VWF:Antigen and vWF:Collagen binding activity levels were significantly higher in the acute than in the disease's convalescence phase, and correlated positively with CRP levels. Neither variable was associated with coronary artery lesions. The vWF:Collagen binding activity/vWF:Antigen ratio, however, was significantly decreased in patients with a coronary artery lesion (z-score > 2; N = 10; mean ratio 0.96 vs. 0.64; p = 0.031) and even more so in those with a coronary artery aneurysm (z-score > 2.5; N = 8; mean ratio 0.94 vs. 0.55; p = 0.02). In a sub-analysis, those patients with a very low ratio in the acute phase presented a persistent coronary artery aneurysm at their 1-year follow-up.Conclusion: This study suggests that comprehensive analysis of vWF parameters may help to both monitor KD inflammation and facilitate the identification of those patients carrying an increased risk for coronary artery lesion.What is Known:⢠Von Willebrand factor (VWF)-parameters represent surrogate markers for vascular inflammation.⢠Kawasaki disease is a generalized vasculitis in children, which can be complicated by coronary artery lesions.What is New:⢠In those Kawasaki disease patients with coronary artery lesions, the vWF:CB/vWF:Ag ratio was significantly decreased.⢠VWF parameters may help to identify patients at risk for coronary artery lesions.

PURPOSE OF THE REVIEW: Targeted pharmacotherapies did improve survival rates, exercise capacity, and quality of life (QoL) of PAH patients. However, these pharmacological interventions are expensive and not always accessible. In addition, not all patients do respond similarly to these medications and many will continue to deteriorate. This review aims to discuss the beneficial role of an artificial right-to-left shunt and highlights current interventional devices and outcomes. RECENT FINDINGS: Since patients with preexisting atrial shunts or patients with Eisenmenger's disease show better survival rates, improved exercise capacity, and QoL, PAH patients clinically do benefit from an atrial septostomy by reducing signs of right heart failure, improving left heart filling, cardiac output, and systemic oxygen transport despite hypoxia. However, an uncontrolled septostomy with unrestricted right-to-left shunt bears the risk of acute severe desaturation and death. The Atrial Flow Regulator (AFR device, Occlutech®, Sweden) provides an adjustable shunt size with restricted flow and excellent short-term outcomes. Interventional strategies for PAH palliation are on the rise. The novel AFR device provides a durable and safe option for a controlled right-to-left shunting, thus enabling an individualized management.

The aim of this registry is to provide data on age-related clinical features of suspected myocarditis and to create a study platform allowing for deriving diagnostic criteria and, at a later stage, testing therapeutic interventions in patients with myocarditis. STUDY DESIGN AND RESULTS: After an initial 6-month pilot phase, MYKKE was opened in June 2014 as a prospective multicenter registry for patients from pediatric heart centers, university hospitals, and community hospitals with pediatric cardiology wards in Germany. Inclusion criteria consisted of age<18 years and hospitalization for suspected myocarditis as leading diagnosis at the discretion of the treating physician. By December 31, 2015, fifteen centers across Germany were actively participating and had enrolled 149 patients. Baseline data reveal 2 age peaks (<2 years, >12 years), show higher proportions of males, and document a high prevalence of severe disease courses in pediatric patients with suspected myocarditis. Severe clinical courses and early adverse events were more prevalent in younger patients and were related to severely impaired leftventricular ejection fraction at initial presentation. SUMMARY: MYKKE represents a multicenter registry and research platform for children and adolescents with suspected myocarditis that achieve steady recruitment and generate a wide range of real-world data on clinical course, diagnostic workup, and treatment of this group of patients. The baseline data reveal the presence of 2 age peaks and provide important insights into the severity of disease in children with suspected myocarditis. In the future, MYKKE might facilitate interventional substudies by providing an established collaborating network using common diagnostic approaches.

May-Thurner syndrome is a venous compression syndrome of the pelvic vessels that represents a relevant risk factor for thrombus formation. The standard procedure to secure a diagnosis is venography, followed by endovascular therapy as the preferred treatment choice if the patient is symptomatic. In our case series, there are three related patients with May-Thurner syndrome. A 16-year-old female was admitted with pulmonary embolism, dyspnoea and hip pain. The compression syndrome was diagnosed with interventional venography, and the patient received venous stent implantation. Due to her family history, we also suspected her mother to be affected by the syndrome and elucidated the diagnosis shortly afterwards by invasive venography. Subsequently, we examined the patient's 19-year-old brother, and magnetic resonance imaging confirmed May-Thurner syndrome. A similar case series has not been published before. In this case, the family relation indicates a possible hereditary aspect of May-Thurner syndrome. This hypothesis should be the subject of further research. In conclusion, it is essential to assess family history thoroughly when treating patients with May-Thurner syndrome.
