Abstract
In Fontan patients, any pulmonary stenosis may impede free passive inflow into the pulmonary circuit and elevate central venous pressure. When stenting such pulmonary stenosis, dislocation of a stent is a feared complication. Here, we report on a successful retrieval of a dislocated Cook Formula stent into the peripheral left pulmonary artery in a Fontan patient with protein-losing enteropathy using a steerable sheath and a grasping forceps. Furthermore, a successful stent implantation for treating the stenosis was possible. Subsequently, we simulated the retraction technique ex vivo. To manage stent dislocation during complex pediatric catheter interventions, we can recommend the use of a steerable sheath guiding a grasping forceps. A dislocated stent can be grasped, completely longitudinally refolded, and safely retrieved.

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
Ebstein's anomaly is a rare congenital heart disease with malformation of the tricuspid valve and myopathy of the right ventricle. The septal and inferior leaflets adhere to the endocardium due to failure of delamination. This leads to apical displacement of their hinge points with a shift of the functional tricuspid valve annulus towards the right ventricular outflow tract with a possibly restrictive orifice. Frequently, a coaptation gap yields tricuspid valve regurgitation and over time the "atrialized" portion of the right ventricle may dilate. The highly variable anatomy determines the clinical presentation ranging from asymptomatic to very severe with need for early operation. Echocardiography and magnetic resonance imaging are the most important diagnostic modalities to assess the tricuspid valve as well as ventricular morphology and function. While medical management of asymptomatic patients can be effective for many years, surgical intervention is indicated before development of significant right ventricular dilatation or dysfunction. Onset of symptoms and arrhythmias are further indications for surgery. Modified cone reconstruction of the tricuspid valve is the state-of-the-art approach yielding the best results for most patients. Alternative procedures for select cases include tricuspid valve replacement and bidirectional cavopulmonary shunt depending on patient age and other individual characteristics. Long-term survival after surgery is favorable but rehospitalization and reoperation remain significant issues. Further studies are warranted to identify the optimal surgical strategy and timing before adverse right ventricular remodeling occurs. It is this article's objective to provide a comprehensive review of current literature and an overview on the management of Ebstein's Anomaly. It focuses on imaging, cardiac surgery, and outcome. Additionally, a brief insight into arrhythmias and their management is given. The "future perspectives" summarize open questions and fields of future research.

Abstract
Partial detachment of the septal and anterior leaflets of the tricuspid valve (TV) is a technique to visualize a perimembranous ventricular septal defect (VSD) for surgical closure in cases where the VSD is obscured by TV tissue. However, TV incision bears the risk of causing relevant postoperative TV regurgitation and higher degree atrioventricular (AV) block. A total of 40 patients were identified retrospectively in our institution who underwent isolated VSD closure between January 2013 and August 2015. Visualization of the VSD was achieved in 20 patients without and in 20 patients with additional partial detachment of the TV. The mean age of patients with partial tricuspid valve detachment (TVD) was 0.7 ± 0.1 years compared with 1 ± 0.3 years (
p
= 0.22) of patients without TVD. There was no difference in cardiopulmonary bypass time between patients of both groups (123 ± 11 vs. 103 ± 5 minutes,
p
= 0.1). Cross-clamp time was longer if the TV was detached (69 ± 5 vs. 54 ± 4 minutes,
p
= 0.023). There was no perioperative mortality. Echocardiography at discharge and after 2.5 years (2 months–6 years) of follow-up showed neither a postoperative increase of tricuspid regurgitation nor any relevant residual shunt. Postoperative electrocardiograms were normal without any sign of higher degree AV block. TVD offers enhanced exposure and safe treatment of VSDs. It did not result in higher rates of TV regurgitation or relevant AV block compared with the control group.

Abstract
Critical Coronavirus disease 2019 (COVID-19) developed in a 7-year-old girl with a history of dystrophy, microcephaly, and central hypothyroidism. Starting with gastrointestinal symptoms, the patient developed severe myocarditis followed by progressive multiple organ failure complicated by Pseudomonas aeruginosa bloodstream infection. Intensive care treatment consisting of invasive ventilation, drainage of pleural effusion, and high catecholamine therapy could not prevent the progression of heart failure, leading to the implantation of venoarterial extracorporeal life support (VA-ECLS) and additional left ventricle support catheter (Impella® pump). Continuous venovenous hemofiltration (CVVH) and extracorporeal hemadsorption therapy (CytoSorb®) were initiated. Whole exome sequencing revealed a mutation of unknown significance in DExH-BOX helicase 30 (DHX30), a gene encoding a RNA helicase. COVID-19 specific antiviral and immunomodulatory treatment did not lead to viral clearance or control of hyperinflammation resulting in the patient’s death on extracorporeal life support-(ECLS)-day 20. This fatal case illustrates the potential severity of pediatric COVID-19 and suggests further evaluation of antiviral treatment strategies and vaccination programs for children.

Abstract
BACKGROUND Pathological cardiac hypertrophy is a result of afterload-increasing pathologies including untreated hypertension and aortic stenosis. It features progressive adverse cardiac remodeling, myocardial dysfunction, capillary rarefaction, and interstitial fibrosis often leading to heart failure. OBJECTIVES This study aimed to establish a novel porcine model of pressure-overload-induced heart failure and to determine the effect of inhibition of microribonucleic acid 132 (miR-132) on heart failure development in this model. METHODS This study developed a novel porcine model of percutaneous aortic constriction by implantation of a percutaneous reduction stent in the thoracic aorta, inducing progressive remodeling at day 56 (d56) after pressure-overload induction. In this study, an antisense oligonucleotide specifically inhibiting miR-132 (antimiR-132), was regionally applied via intracoronary injection at d0 (percutaneous transverse aortic constriction induction) and d28. RESULTS At d56, antimiR-132 treatment diminished cardiomyocyte cross-sectional area (188.9 ± 2.8 vs. 258.4 ± 9.0 μm2 in untreated hypertrophic hearts) and improved global cardiac function (ejection fraction 48.9 ± 1.0% vs. 36.1 ± 1.7% in control hearts). Moreover, at d56 antimiR-132-treated hearts displayed less increase of interstitial fibrosis compared with sham-operated hearts (Δsham 1.8 ± 0.5%) than control hearts (Δsham 10.8 ± 0.6%). Of note, cardiac platelet and endothelial cell adhesion molecule 1+ capillary density was higher in the antimiR-132-treated hearts (647 ± 20 cells/mm2) compared with in the control group (485 ± 23 cells/mm2). CONCLUSIONS The inhibition of miR-132 is a valid strategy in prevention of heart failure progression in hypertrophic heart disease and may be developed as a treatment for heart failure of nonischemic origin.

Abstract
Patients undergoing complex pediatric cardiac surgery in early infancy are at risk of postoperative secondary end-organ dysfunction. The aim of this study was to determine specific risk factors promoting the development of peri- and postoperative hepatopathy after surgery for congenital heart disease. In this retrospective study, we identified 20 consecutive patients operated between 2011 and 2019 from our institutional cohort who developed significant postsurgical hepatic dysfunction. These patients were compared to a control group of 30 patients with comparable initial cardiac conditions and STS-EACTS risk score. Patients who developed hepatopathy in the intensive care unit have chronic cholestasis and decreased liver synthesis. The impact of postoperative hepatopathy on morbidity was marked. In six patients (30%), liver transplantation was executed as ultima ratio, and two (10%) were listed for liver transplantation. The overall mortality related to postoperative hepatopathy is high: We found nine patients (45%) having severe hepatopathy and mostly multiple organ dysfunction who died in the postoperative course. According to risk analysis, postoperative right and left heart dysfunction in combination with a postoperative anatomical residuum needing a re-operation or re-intervention in the postoperative period is associated with a high risk for the development of cardiac hepatopathy. Furthermore, postoperative complications (pleural effusion, heart rhythm disorders, etc.), postoperative infections, and the need for parenteral nutrition also raise the risk for cardiac hepatopathy. Further investigations are needed to reduce hepatic complications and improve the general prognosis of such complex patients.

Abstract
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.

Abstract
OBJECTIVE This study presents data from the admission trial to show the feasibility, safety and effectiveness of the Nit-Occlud® Lê VSD in the treatment of perimembranous ventricular septal defects with an aneurysmal configuration and a diameter up to 8 mm. BACKGROUND The majority of ventricular septal defects (VSD) are still closed surgically, while a less invasive transcatheter treatment by closure devices is available. Device-based closure is reported to be associated with the risk of complete atrio-ventricular block, especially with double-disc devices in perimembranous defects. METHODS In six tertiary centers in Germany and Israel, an interventional closure of a periembranous VSD was attempted in 88 patients using the Nit-Occlud® Lê VSD. RESULTS The interventional VSD closure was performed in 85 patients. Patients had a median age of 8.0 (2-65) years and a median body weight of 26.7 (10-109) kg. A complete closure of the defects was achieved in 85.4% 2 weeks after device implantation, in 88.9% after three months and in 98.6% at the 5-year follow-up. There was no incidence of death during the study nor did any patient suffer of permanent atrio-ventricular block of higher degree. Serious adverse events, by definition, are potentially life-threatening or require surgery to correct, while major serious events require medical or transcatheter intervention to correct. The study results exhibit a serious adverse event rate of 3.5% (3/85 patients) and a major adverse event rate of 5.9% (5/85 patients). CONCLUSION The Nit-Occlud® Lê VSD coil offers the possibility of an effective and safe approach in patients with aneurysmal perimembranous ventricular septal defects.

Abstract
Currently, no reliable genotype–phenotype correlation is available for pediatric Marfan patients in everyday clinical practice. We investigated correlations of FBN1 variants with the prevalence and age of onset of Marfan manifestations in childhood and differentiated three groups: missense/in-frame, splice, and nonsense/frameshift variants. In addition, we differentiated missense variants destroying or generating a cysteine (cys-missense) and alterations not affecting cysteine. We categorized 105 FBN1-positive pediatric patients. Patients with cys-missense more frequently developed aortic dilatation (p = 0.03) requiring medication (p = 0.003), tricuspid valve prolapse (p = 0.03), and earlier onset of myopia (p = 0.02) than those with other missense variants. Missense variants correlated with a higher prevalence of ectopia lentis (p = 0.002) and earlier onset of pulmonary artery dilatation (p = 0.03) than nonsense/frameshift, and dural ectasia was more common in the latter (p = 0.005). Pectus excavatum (p = 0.007) appeared more often in patients with splice compared with missense/in-frame variants, while hernia (p = 0.04) appeared earlier in the latter. Findings on genotype–phenotype correlations in Marfan-affected children can improve interdisciplinary therapy. In patients with cys-missense variants, early medical treatment of aortic dilatation seems reasonable and early regular ophthalmologic follow-up essential. Patients with nonsense/frameshift and splice variants require early involvement of orthopedic specialists to support the growing child.

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
INTRODUCTION Veno-arterial extracorporeal membrane oxygenation is well-established for pediatric patients with post-cardiotomy heart failure. However, extracorporeal membrane oxygenation support is associated with major complications, that is, hemorrhage and thromboembolism. We seek to report our experience with delayed systemic heparinization during neonatal cardiac extracorporeal membrane oxygenation and its impact on bleeding and thromboembolism. METHODS We retrospectively identified 15 consecutive neonates who were placed on extracorporeal membrane oxygenation after congenital heart surgery during a period of 3 years (2015-2017). Our anticoagulation protocol consisted of full heparin reversal by protamine after switching from cardiopulmonary bypass to extracorporeal membrane oxygenation (target activated clotting time: 120 ± 20 seconds). Administration of systemic heparinization was delayed until postoperative drainage volume declined to <1 mL/kg/h. Primary study endpoints were thromboembolism, bleeding, and requirement of blood products on extracorporeal membrane oxygenation. RESULTS Our cohort (mean age: 13 ± 2.6 days; mean weight: 3.1 ± 0.3 kg; 66.7% male) required post-cardiotomy extracorporeal membrane oxygenation with a mean support time of 4.5 ± 2.2 days. Systemic heparinization was delayed averagely for 18.1 ± 9.3 hours. No thromboembolic events were observed on extracorporeal membrane oxygenation or after weaning. Relevant surgical site bleeding occurred in two patients (13.3%) requiring re-thoracotomy on the first postoperative day. Analysis of transfusion volumes revealed 24.5 ± 21.9 mL/kg/d mean packed red blood cells, 9.6 ± 7.1 mL/kg/d mean fresh frozen plasma, and 7.5 ± 5.7 mL/kg/d mean platelets. In-hospital survival was 86.6% (n = 13). CONCLUSION In this retrospective analysis, the results of delayed systemic heparinization in neonatal post-cardiotomy extracorporeal membrane oxygenation could lead one to conclude that this routine is safe and favorable with low risk for thromboembolic events, reduced postoperative hemorrhage, and reduced blood product utilization.

Abstract
Zusammenfassung
Eine pathologische Druckerhöhung im pulmonalen Gefäßsystem (pulmonale Hypertonie, PH) wurde bisher definiert durch einen invasiv gemessenen mittleren pulmonalarteriellen Druck (mPAP) ≥25 mm Hg in Ruhe. Auf dem 6th World Symposium on Pulmonary Hypertension (WSPH) in Nizza 2018 wurde eine neue Definition der PH vorgeschlagen, die die Senkung der Obergrenze des normalen mPAP von 24 auf 20 mm Hg beinhaltet.
Obwohl keine Evidenz aus pädiatrischen Studien hierfür vorliegt, wurde diese neue PH-Definition (mPAP >20 mm Hg) aus Gründen der Einheitlichkeit auch von der pädiatrischen „Task Force“ des WSPH 2018 übernommen.
Die vorliegende Stellungnahme der Arbeitsgemeinschaft Pulmonale Hypertonie (AGPH) der Deutschen Gesellschaft für Pädiatrische Kardiologie und angeborene Herzfehler e. V. (DGPK) erläutert die zugrunde liegende Rationale und mögliche Konsequenzen dieser Definitionsänderung. Insbesondere stellt sie klar, dass diese Änderung der Definition aktuell keinen Einfluss auf die Verschreibung von Medikamenten zur gezielten spezifischen Therapie der pulmonalarteriellen Hypertonie hat.

Abstract
Objective: To assess the efficacy and safety of the Nit-Occlud ASD-R (PFM S.R.L, La Paz, Bolivia) in the percutaneous closure of secundum atrial septal defects (ASD). Patients and Methods: Fifty-three consecutive patients with median age of 11 years (range 3-67) and mean weight 27.1 kg (range 13-75 kg), treated in two cardiology centers between May 2007 and March 2011. Results: Mean fluoroscopy time was 14 minutes (5-53), mean procedure time was 70 minutes (45-150), mean defect size, as measured by the stop-flow technique, was 17.8 mm (5.6-31), and mean stent size of the implanted device was 18 mm (6-28), which is 0.98 times the defect size. Successful closure of the ASD without major complications was achieved in 49 of 53 patients. In 71.4% of patients in whom device implantation was accomplished, there was no evidence of a persistent shunt at the completion of the procedure. This closure rate increased to 91.7% after 24 hours, with 95.8% closure after three months and 100% closure after six months. Device embolization occurred in one patient within 24 hours of implantation and required surgical device removal and ASD closure. There were no other major complications and no deaths during the period of follow-up (average 72 months; range 59-105 months). Conclusion: The Nit-Occlud ASD-R device is safe and effective with very good closure rates.

Abstract
The European Pediatric Pulmonary Vascular Disease Network is a registered, non-profit organization that strives to define and develop effective, innovative diagnostic methods and treatment options in all forms of pediatric pulmonary hypertensive vascular disease, including pulmonary hypertension (PH) associated with bronchopulmonary dysplasia, PH associated with congenital heart disease (CHD), persistent PH of the newborn, and related cardiac dysfunction. The executive writing group members conducted searches of the PubMed/MEDLINE bibliographic database (1990-2018) and held face-to-face and web-based meetings. Ten section task forces voted on the updated recommendations, based on the 2016 executive summary. Clinical trials, meta-analyses, guidelines, and other articles that include pediatric data were searched using the term "pulmonary hypertension" and other keywords. Class of recommendation (COR) and level of evidence (LOE) were assigned based on European Society of Cardiology/American Heart Association definitions and on pediatric data only, or on adult studies that included >10% children or studies that enrolled adults with CHD. New definitions by the World Symposium on Pulmonary Hypertension 2018 were included. We generated 10 tables with graded recommendations (COR/LOE). The topics include diagnosis/monitoring, genetics/biomarkers, cardiac catheterization, echocardiography, cardiac magnetic resonance/chest computed tomography, associated forms of PH, intensive care unit/lung transplantation, and treatment of pediatric PH. For the first time, a set of specific recommendations on the management of PH in middle- and low-income regions was developed. Taken together, these executive, up-to-date guidelines provide a specific, comprehensive, detailed but practical framework for the optimal clinical care of children and young adults with PH.

Abstract
Isolated unilateral absence of a pulmonary artery (UAPA) is a rare congenital anomaly in which one branch pulmonary artery has no connection to the main pulmonary trunk (most often there is ductal origin). Without treatment, it may lead to ipsilateral pulmonary hypoplasia and contralateral pulmonary artery hypertension. To avoid these complications, early surgical repair of UAPA is necessary. Surgical strategies include direct anastomosis between the "isolated" branch pulmonary artery (PA) and the main pulmonary trunk or creation of an interposition graft using prosthetic material or flap techniques. We describe a surgical technique using a totally autologous interposition tube graft.

Abstract
Alveolar capillary dysplasia (ACD) is a rare neonatal lung disease characterized anatomically by a defective and hypoplastic development of pulmonary alveoli leading to persistent pulmonary hypertension (PPHN) and finally lethal respiratory failure. It is often associated with congenital left heart obstruction. Given the fatal prognosis an early diagnosis is important. However, due to the fast onset of PPHN in neonates and lack of pathognomonic signs for its cause, safe and fast detection of ACD is challenging. Therefore, following the exclusion of cardiac and common pulmonary causes, lung biopsy becomes essential for diagnosis.We hereby report a case of ACD with atrial septal defect type one and hypoplastic aortic arch with an ante-mortem diagnosis and discuss the current state of medicine in relation to ACD.

Abstract
Aortic valve repair in adult congenital heart disease (ACHD) went through a major development during the last two decades to become an increasingly established treatment option in experienced heart valve repair centers. This mini-review addresses valve-sparing treatment strategies in the two most common clinical entities of patients with adult congenital aortic valve disease, namely those presenting with bicuspid (BAV) and unicuspid (UAV) aortic valve disease. Both diseases are integral components of the continuum of congenital aortic valve diseases and represent one of the most common reasons of cardiovascular morbidity in young and otherwise healthy adult patients. The review will highlight the most important advantages of aortic valve sparing procedures as compared to the conventional valve replacement strategy. New treatment aspects will be reviewed including minimally-invasive surgical approaches for aortic valve repair as well as modern protocols of enhanced perioperative recovery which will potentially improve the perioperative recovery and quality of life of the patients undergoing valve-sparing surgical procedures in the future.
