Abstract
Traditional cardiovascular risk factors put patients with congenital heart disease (CHD) at increased risk for cardiovascular morbidity and mortality. The aim of this study was to evaluate whether body mass index (BMI) is associated with health-related quality of life (HRQoL) in patients with variants of Tetralogy of Fallot (TOF). Patients and parents of children with variants of TOF-CHD were asked to fill out the PedsQL 4.0 questionnaire and provide weight and length. Patients were categorized into low, normal, and high BMI percentiles. Other demographic data were obtained from the Swedish national registry for congenital heart disease (SWEDCON). Statistical analyses included non-parametric Mann-Whitney U test, Fisher exact, and Chi-square tests. Eighty-five patients were included. Twelve were overweight or obese, 57 had a normal BMI, and 16 were underweight. There was a significant difference in age and gender between the groups. Comparing overweight/obese children to those with normal BMI, physical and social functioning were impaired, while emotional and school function were comparable between the groups. This applied to both child and parental assessment. When comparing underweight to normal weight children, school functioning assessed by the parent was the only domain significantly different from patients with a normal BMI. Children with variants of TOF and overweight/obesity have lower HRQoL, particularly in physical and social functioning, while underweight children may have impaired school functioning. We suggest that preventive measures aimed at maintaining a normal weight should be taken early in life to reduce long-term cardiovascular risk in the CHD population.

Abstract
OBJECTIVES Pregnancy-related physiological adaptations result in increased heart rate as well as electrocardiographic changes such as a mean QTc prolongation of 27 ms. Pregnant women with CHD are at increased risk for cardiovascular complications. The aim of this study was to identify risk factors for abnormally prolonged QTc interval-a risk factor for ventricular arrhythmias-in pregnant women with CHD. MATERIAL AND METHOD Retrospective longitudinal single-centre study. Pre-pregnancy demographic and electrocardiographic risk factors for abnormal QTc duration during pregnancy of (a) > 460 ms and (b) >27 ms increase were analyzed. RESULTS Eighty-three pregnancies in 63 women were included, of which three had documented arrhythmias. All five Modified World Health Organization Classification of Maternal Cardiovascular Risk (mWHO) classes were represented, with 15 pregnancies (18.1%) in mWHO class I, 26 (31.3%) in mWHO II, 28 (33.7%) in mWHO II-III, 11 (13.3%) in mWHO III, and three pregnancies (3.6%) in mWHO class IV. Heart rate and QTc interval increased, while QRS duration and PR interval shortened during pregnancy. QTc duration of > 460 ms was associated with increased pre-pregnancy QTc interval, QRS duration, and weight, as well as body mass index. QTc increase of > 27 ms was associated with increased heart rate prior to pregnancy. No significant associations of electrocardiographic changes with mWHO class or CHD type were identified. CONCLUSION Increased QTc in pregnant women with CHD was associated with being overweight or having higher heart rate, QRS, or QTc duration prior to pregnancy. These patients should be monitored closely for arrhythmias during pregnancy.

Abstract
Aims The aim of this study was to investigate circulating ceramides involved in cardiovascular disease (CVD) in young adult childhood cancer survivors (CCS) and their correlations to previously reported adverse cardiovascular changes in this cohort. Methods and results Fifty-seven CCS and 53 healthy controls (age 20-30 years) were studied. Plasma long-chain ceramides, known to be cardiotoxic (C16:0, C18:0, C24:0, and C24:1), were analysed by mass spectrometry. The coronary event risk test 2 (CERT2) score was calculated from the ceramide data. Cardiac and carotid artery ultrasound data and lipid data available from previous studies of this cohort were used to study partial correlations with ceramide and CERT2 score data. All four analysed ceramides were elevated in CCS compared with controls (P ≤ 0.012). The greatest difference was noted for C18:0, which was 33% higher in CCS compared with controls adjusted for sex, age, and body mass index (BMI) (P < 0.001). The CERT2 score was higher in CCS compared with controls (P < 0.001). In the CCS group, 35% had a high to very high CERT2 score (7-12) when compared with 9% in the control group (P < 0.001). The CCS subgroup with a CERT2 score ≥ 7 had higher heart rate, systolic blood pressure, and higher levels of apolipoprotein B compared with CCS with a CERT2 score < 6 (P ≤ 0.011). When adjusted for age, sex, and BMI, CERT2 score was significantly correlated with arterial stiffness, growth hormone, and cranial radiotherapy (P < 0.044). Conclusion Ceramides could be important biomarkers in understanding the pathophysiology of CVD and in predicting CVD disease risk in young adult CCS.

Abstract
INTRODUCTION Proteomics may help discover novel biomarkers and underlying mechanisms for cardiovascular disease. This could be useful for childhood cancer survivors as they show an increased risk of cardiovascular disease. The aim of this study was to investigate circulating cardiovascular proteins in young adult survivors of childhood cancer and their relationship to previously reported subclinical cardiovascular disease. METHODS Ninety-two cardiovascular proteins were measured in 57 childhood cancer survivors and in 52 controls. For proteins that were significantly different between childhood cancer survivors and controls, we performed correlations between protein levels and measures of peripheral arterial stiffness (carotid distensibility and stiffness index, and augmentation index) and endothelial dysfunction (reactive hyperemia index). RESULTS Leptin was significantly higher in childhood cancer survivors compared to controls (normalized protein expression units: childhood cancer survivors 6.4 (1.5) versus 5.1 (1.7), p < 0.0000001) after taking multiple tests into account. Kidney injury molecule-1, MER proto-oncogene tyrosine kinase, selectin P ligand, decorin, alpha-1-microglobulin/bikunin precursor protein, and pentraxin 3 showed a trend towards group differences (p < 0.05). Among childhood cancer survivors, leptin was associated with anthracycline treatment after adjustment for age, sex, and body mass index (p < 0.0001). Higher leptin correlated with lower carotid distensibility after adjustment for age, sex, body mass index, and treatments with radiotherapy and anthracyclines (p = 0.005). CONCLUSION This proteomics approach identified that leptin is higher in young asymptomatic adult survivors of childhood cancer than in healthy controls and is associated with adverse vascular changes. This could indicate a role for leptin in driving the cardiovascular disease burden in this population.

Abstract
Background Severe left-sided cardiac obstructions are associated with high morbidity and mortality if not detected in time. The correct prenatal diagnosis of coarctation of the aorta (CoA) is difficult. Fetal cardiac magnetic resonance imaging (CMR) may improve the prenatal diagnosis of complex congenital heart defects. Flow measurements in the ascending aorta could aid in predicting postnatal CoA, but its accurate visualization is challenging. Objectives To compare the flow in the descending aorta (DAo) and umbilical vein (UV) in fetuses with suspected left-sided cardiac obstructions with and without the need for postnatal intervention and healthy controls by fetal phase-contrast CMR flow. A second objective was to determine if adding fetal CMR to echocardiography (echo) improves the fetal CoA diagnosis. Methods Prospective fetal CMR phase-contrast flow in the DAo and UV and echo studies were conducted between 2017 and 2022. Results A total of 46 fetuses with suspected left-sided cardiac obstructions [11 hypoplastic left heart syndrome (HLHS), five critical aortic stenosis (cAS), and 30 CoA] and five controls were included. Neonatal interventions for left-sided cardiac obstructions (n = 23) or comfort care (n = 1 with HLHS) were pursued in all 16 fetuses with suspected HLHS or cAS and in eight (27%) fetuses with true CoA. DAo or UV flow was not different in fetuses with and without need of intervention. However, DAo and UV flows were lower in fetuses with either retrograde isthmic systolic flow [DAo flow 253 (72) vs. 261 (97) ml/kg/min, p = 0.035; UV flow 113 (75) vs. 161 (81) ml/kg/min, p = 0.04] or with suspected CoA and restrictive atrial septum [DAo flow 200 (71) vs. 268 (94) ml/kg/min, p = 0.04; UV flow 89 vs. 159 (76) ml/kg/min, p = 0.04] as well as in those without these changes. Adding fetal CMR to fetal echo predictors for postnatal CoA did not improve the diagnosis of CoA. Conclusion Fetal CMR-derived DAo and UV flow measurements do not improve the prenatal diagnosis of left-sided cardiac obstructions, but they could be important in identifying fetuses with a more severe decrease in blood flow across the left side of the heart. The physiological explanation may be a markedly decreased left ventricular cardiac output with subsequent retrograde systolic isthmic flow and decreased total DAo flow.

Abstract
Background Pulmonary hypertension (PH) is diagnosed based on an invasive evaluation of the mean pulmonary artery (PA) pressure. The morphological assessment of the pulmonary arteries was only recently not feasible. With the advent of optical coherence tomography (OCT)-imaging, an accessible tool allows to study PA morphology longitudinally. The primary hypothesis was that OCT distincts the PA structure of PH patients from control subjects. The secondary hypothesis was that PA wall thickness (WT) correlates with the progression of PH. Methods This is a retrospective monocentric study of 28 paediatric patients with (PH group) and without PH (control group) who had undergone cardiac catheterisation including OCT imaging of the PA branches. OCT parameters analysed were WT and the quotient of WT and diameter (WT/DM) and those were compared between the PH group and the control group. In addition, the OCT parameters were aligned with the haemodynamic parameters to evaluate the potential of OCT as a risk factor for patients with PH. Results WT and WT/DM in the PH group were significantly higher compared to the control group {WT: 0.150 [0.230, range (R): 0.100-0.330] vs. 0.100 [0.050, R: 0.080-0.130] mm, P<0.001; WT/DM: 0.06 [0.05] vs. 0.03 [0.01], P=0.006}. There were highly significant correlations between WT and WT/DM with the haemodynamic parameters mean pulmonary arterial pressure (mPAP) [Spearman correlation coefficient (rs) =0.702, P<0.001; rs=0.621, P<0.001], systolic pulmonary arterial pressure (sPAP) (rs=0.668, P<0.001; rs=0.658, P<0.001) and WT and pulmonary vascular resistance (PVR) (rs=0.590, P=0.02). Also, there was a significant correlation between WT and WT/DM and the risk factors quotient of mPAP and mean systemic arterial pressure (mSAP) (mPAP/mSAP) (rs=0.686, P<0.001; rs=0.644, P<0.001) and pulmonary vascular resistance index (PVRI) (rs=0.758, P=0.002; rs=0.594, P=0.02). Conclusions OCT can detect significant differences in WT of the PA in patients with PH. Furthermore, the OCT parameters correlate significantly with haemodynamic parameters and risk factors for patients with PH. More investigations are required to evaluate to what extent the impact of OCT can contribute to the clinical care of children with PH.

Abstract
Abnormal left ventricular contractile reserve (LVCR) is associated with adverse cardiac outcomes in different patient cohorts and might be useful in the detection of cardiomyopathy in childhood cancer survivors (CCS) after cardiotoxic treatment. The aim of this study was to evaluate LVCR by dobutamine stress echocardiography (DSE) combined with measures of myocardial strain in CCS previously treated with anthracyclines (AC). Fifty-three CCS (age 25.34 ± 2.44 years, 35 male) and 53 healthy controls (age 24.40 ± 2.40 years, 32 male) were included. Subjects were examined with echocardiography at rest, at low-dose (5 micrograms/kg/min), and at high-dose (40 micrograms/kg/min) dobutamine infusion. Left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS), strain rate (GSR), and early diastolic strain rate (GEDSR) at different DSE phases were used as measures of LVCR. The mean follow-up time among CCS was 15.8 ± 5.8 years. GLS, GSR, and LVEF were lower at rest in CCS compared to controls (p ≤ 0.03). LVEF was within the normal range in CCS. ΔGLS, ΔGSR, and ΔGEDSR but not ΔLVEF were lower in CCS compared to controls after both low- (p ≤ 0.048) and high-dose dobutamine infusion (p ≤ 0.023). We conclude that strain measures during low-dose DSE detect impaired myocardial contractile reserve in young CCS treated with AC at 15-year follow-up. Thus, DSE may help identify asymptomatic CCS at risk for heart failure and allows for tailored follow-up accordingly.

Abstract
BACKGROUND Neonates with critical congenital heart disease require early intervention. Four-dimensional (4D) flow may facilitate surgical planning and improve outcome, but accuracy and precision in neonates are unknown. PURPOSE To 1) validate two-dimensional (2D) and 4D flow MRI in a phantom and investigate the effect of spatial and temporal resolution; 2) investigate accuracy and precision of 4D flow and internal consistency of 2D and 4D flow in neonates; and 3) compare scan time of 4D flow to multiple 2D flows. STUDY TYPE Phantom and prospective patients. POPULATION A total of 17 neonates with surgically corrected aortic coarctation (age 18 days [IQR 11-20]) and a three-dimensional printed neonatal aorta phantom. FIELD STRENGTH/SEQUENCE 1.5T, 2D flow and 4D flow. ASSESSMENT In the phantom, 2D and 4D flow volumes (ascending and descending aorta, and aortic arch vessels) with different resolutions were compared to high-resolution reference 2D flow. In neonates, 4D flow was compared to 2D flow volumes at each vessel. Internal consistency was computed as the flow volume in the ascending aorta minus the sum of flow volumes in the aortic arch vessels and descending aorta, divided by ascending aortic flow. STATISTICAL TESTS Bland-Altman plots, Pearson correlation coefficient (r), and Student's t-tests. RESULTS In the phantom, 2D flow differed by 0.01 ± 0.02 liter/min with 1.5 mm spatial resolution and -0.01 ± 0.02 liter/min with 0.8 mm resolution; 4D flow differed by -0.05 ± 0.02 liter/min with 2.4 mm spatial and 42 msec temporal resolution, -0.01 ± 0.02 liter/min with 1.5 mm, 42 msec resolution and -0.01 ± 0.02 liter/min with 1.5 mm, 21 msec resolution. In patients, 4D flow and 2D flow differed by -0.06 ± 0.08 liter/min. Internal consistency in patients was -11% ± 17% for 2D flow and 5% ± 13% for 4D flow. Scan time was 17.1 minutes [IQR 15.5-18.5] for 2D flow and 6.2 minutes [IQR 5.3-6.9] for 4D flow, P < 0.0001. DATA CONCLUSION Neonatal 4D flow MRI is time efficient and can be acquired with good internal consistency without contrast agents or general anesthesia, thus potentially expanding 4D flow use to the youngest and smallest patients. EVIDENCE LEVEL 1 TECHNICAL EFFICACY: Stage 2.

Abstract
Definition and management of arterial hypertension in children and adolescents are uncertain, due to different positions of current guidelines. The European Society of Cardiology task-force, constituted by Associations and Councils with interest in arterial hypertension, has reviewed current literature and evidence, to produce a Consensus Document focused on aspects of hypertension in the age range of 6-16 years, including definition, methods of measurement of blood pressure, clinical evaluation, assessment of hypertension-mediated target organ damage, evaluation of possible vascular, renal and hormonal causes, assessment and management of concomitant risk factors with specific attention for obesity, and anti-hypertensive strategies, especially focused on life-style modifications. The Consensus Panel also suggests aspects that should be studied with high priority, including generation of multi-ethnic sex, age and height specific European normative tables, implementation of randomized clinical trials on different diagnostic and therapeutic aspects, and long-term cohort studies to link with adult cardiovascular risk. Finally, suggestions for the successful implementation of the contents of the present Consensus document are also given.

Abstract
Background: Marfan Syndrome (MFS) has been associated with increased aortic stiffness and left ventricular dysfunction. The latter may be due to the underlying genotype and/or secondary to aortic stiffening (vascular-ventricular interaction). The aim of this study was to characterize arterial and cardiac function in MFS using a multimodal approach. Methods: Prospective observational study of MFS patients and healthy controls. Methods included echocardiography, ascending aortic distensibility, common carotid intima media thickness [cIMT], parameters of wave reflection, carotid-femoral pulse wave velocity [cfPWV]), reactive hyperemia index [RHI], and biomarker analysis (Olink, CVII panel). Results: We included 20 patients with MFS and 67 controls. Ascending aortic distensibility, cIMT and RHI were decreased, while all parameters of arterial wave reflection, stiffness and BNP levels were increased in the MFS group. Both systolic and diastolic function were impaired relative to controls. Within the MFS group, no significant correlation between arterial and cardiac function was identified. However, cfPWV correlated significantly with indexed left ventricular mass and volume in MFS. Bran natriuretic peptide (BNP) was the only biomarker significantly elevated in MFS following correction for age and sex. Conclusions: MFS patients have generally increased aortic stiffness, endothelial dysfunction and BNP levels while cIMT is decreased, supporting that the mechanism of general stiffening is different from acquired vascular disease. CfPWV is associated with cardiac size, blood pressure and BNP in MFS patients. These may be early markers of disease progression that are suitable for monitoring pharmacological treatment effects in MFS patients.

Abstract
Background
Hypoplastic left heart syndrome is associated with significant morbidity and mortality. We aimed to assess the influence of left ventricular morphology and choice of shunt on adverse outcome in patients with hypoplastic left heart syndrome and stage 1 palliation.
Methods and Results
This was a retrospective analysis of patients with hypoplastic left heart syndrome with stage 1 palliation between 1999 and 2018 in Sweden. Patients (n=167) were grouped based on the anatomic subtypes aortic‐mitral atresia, aortic atresia‐mitral stenosis (AA‐MS), and aortic‐mitral stenosis. The left ventricular phenotypes including globular left ventricle (Glob‐LV), miniaturized and slit‐like left ventricle (LV), and the incidence of major adverse events (MAEs) including mortality were assessed. The overall mortality and MAEs were 31% and 41%, respectively. AA‐MS (35%) was associated with both mortality (all other subtypes versus AA‐MS: interstage‐I: hazard ratio [HR], 2.7;
P
=0.006; overall: HR, 2.2;
P
=0.005) and MAEs (HR, 2.4;
P
=0.0009). Glob‐LV (57%), noticed in all patients with AA‐MS, 61% of patients with aortic stenosis‐mitral stenosis, and 19% of patients with aortic atresia‐mitral atresia, was associated with both mortality (all other left ventricular phenotypes versus Glob‐LV: interstage‐I: HR, 4.5;
P
=0.004; overall: HR, 3.4;
P
=0.0007) and MAEs (HR, 2.7;
P
=0.0007). There was no difference in mortality and MAEs between patients with AA‐MS and without AA‐MS with Glob‐LV (
P
>0.15). Patients with AA‐MS (35%) or Glob‐LV (38%) palliated with a Blalock‐Taussig shunt had higher overall mortality compared with those palliated with Sano shunts, irrespective of the stage 1 palliation year (AA‐MS: HR, 2.6;
P
=0.04; Glob‐ LV: HR, 2.1;
P
=0.03).
Conclusions
Glob‐LV and AA‐MS are independent morphological risk factors for adverse short‐ and long‐ term outcome, especially if a Blalock‐Taussig shunt is used as part of stage 1 palliation. These findings are important for the clinical management of patients with hypoplastic left heart syndrome.

Abstract
Pulmonary vasodilator therapy is still often an off-label treatment for pulmonary hypertension in children. The aim of this nationwide register-based study was to assess patient characteristics and strategies for pulmonary vasodilator therapy in young Swedish children. Prescription information for all children below seven years of age at treatment initiation, between 2007 and 2017, was retrieved from the National Prescribed Drug Register, and medical information was obtained by linkage to other registers. All patients were categorized according to the WHO classification of pulmonary hypertension. In total, 233 patients had been prescribed pulmonary vasodilators. The treatment was initiated before one year of age in 61% (N = 143). Sildenafil was most common (N = 224 patients), followed by bosentan (N = 29), iloprost (N = 14), macitentan (N = 4), treprostinil (N = 2) and riociguat (N = 2). Over the study period, the prescription rate for sildenafil tripled. Monotherapy was most common, 87% (N = 203), while 13% (N = 20) had combination therapy. Bronchopulmonary dysplasia (N = 82, 35%) and/or congenital heart defects (N = 156, 67%) were the most common associated conditions. Eight percent (N = 18) of the patients had Down syndrome. Cardiac catheterization had been performed in 39% (N = 91). Overall mortality was 13% (N = 30) during the study period. This study provides an unbiased overview of national outpatient use of pulmonary vasodilator therapy in young children. Few cases of idiopathic pulmonary arterial hypertension were found, but a large proportion of pulmonary hypertension associated with congenital heart defects or bronchopulmonary dysplasia. Despite treatment, mortality was high, and additional pediatric studies are needed for a better understanding of underlying pathologies and evidence of treatment effects.

Abstract
Background: Bicuspid aortic valve (BAV), the most common congenital cardiac anomaly, has been associated with an aortopathy, increased aortic stiffness and diastolic dysfunction. The involved mechanisms and impact of age remain unclear. It was the aim of this study to characterize arterial and cardiac function, their correlation, and the effect of age in children and adults with a history of BAV. Methods: Multimodal cardiovascular assessment included echocardiography, ascending aortic distensibility, common carotid intima media thickness [cIMT], parameters of wave reflection [central (cAIx75) and peripheral (pAIx75) augmentation index corrected to a heart rate of 75/min, aging index (AI)], carotid-femoral pulse wave velocity [cfPWV], and endothelial function (EndoPAT). Multivariable linear regression and correlation analyses were performed. Results: We included 47 BAV patients and 84 controls (age 8–65 years). Ascending aortic stiffness, pulse wave reflection (cAIx75, pAIx75, and AI) and central blood pressure were significantly increased in patients with BAV. However, PWV, cIMT, and endothelial function were not significantly different from controls. BAV patients had marginally reduced diastolic (E': β = −1.5, p < 0.001) but not systolic function compared to controls. Overall, all parameters of arterial stiffness had moderate-strong correlations with diastolic dysfunction and age. In the BAV group, ascending aortic distensibility had the strongest correlation with diastolic dysfunction. Conclusions: BAV is associated with increased proximal arterial stiffness and wave reflection. However, PWV and cIMT are not increased, and endothelial function is preserved. This suggests that the mechanism of arterial and cardiac stiffening is different from patients with acquired heart diseases.

Abstract
Background: Childhood cancer survivors (CCS) are at an increased risk for cardiovascular diseases (CVD). It was the primary aim of this study to determine different measures of cardiac, carotid, lipid, and apolipoprotein status in young adult CCS and in healthy controls. Methods: Cardiac and common carotid artery (CCA) structure and function were measured by ultrasonography. Lipids and apolipoproteins were measured in the blood. Peripheral arterial endothelial vasomotor function was assessed by measuring digital reactive hyperemia index (PAT-RHI) using the Endo-PAT 2000. Results: Fifty-three CCS (20-30 years, 35 men) and 53 sex-matched controls were studied. The CCS cohort was divided by the median dose of anthracyclines into a low anthracycline dose (LAD) group (50-197 mg/m2, n = 26) and a high anthracycline dose (HAD) group (200-486 mg/m2, n = 27). Carotid distensibility index (DI) and endothelial function determined by PAT-RHI were both lower in the CCS groups compared with controls (p < 0.05 and p = 0.02). There was no difference in carotid intima media thickness. Atherogenic apolipoprotein-B (Apo-B) and the ratio between Apo-B and Apoliprotein-A1 (Apo-A1) were higher in the HAD group compared with controls (p < 0.01). Apo-B/Apo-A1-ratio was over reference limit in 29.6% of the HAD group, in 15.4% of LAD group, and in 7.5% of controls (p = 0.03). Measured lipid markers (low density lipoprotein and total cholesterol and triglycerides) were higher in both CCS groups compared with controls (p < 0.05). Systolic and diastolic function were measurably decreased in the HAD group, as evidenced by lower EF (p < 0.001) and lower é-wave (p < 0.005) compared with controls. CCA DI correlated with Apo-B/Apo-A1-ratio and Apo-A1. Follow-up time after treatment correlated with decreased left ventricular ejection fraction (p = 0.001). Conclusion: Young asymptomatic CCS exhibit cardiac, vascular, lipid, and apolipoprotein changes that could account for increased risk for CVD later in life. These findings emphasize the importance of cardiometabolic monitoring even in young CCS.

Abstract
BACKGROUND Coarctation of the Aorta (CoA) is associated with increased aortic stiffness and diastolic left ventricular dysfunction. The mechanisms involved and impact of age remain unclear. It was the aim of this study to characterize arterial and cardiac function, their correlation, and the effect of age in children and adults with repaired CoA. METHODS Multimodal cardiovascular assessment from the ascending aorta to microcirculation and endothelial function was performed prospectively. Statistical analyses included multivariable linear regression and correlation of vascular parameters with age and diastolic function. RESULTS Fifty-seven patients with well-repaired CoA and 77 healthy controls were included (age 8-59). There was no significant difference in age, gender, body surface area and BMI between the groups. Ascending aortic distensibility was decreased while common carotid intima media thickness, central augmentation index corrected to a heart rate of 75/min [Aix75], peripheral Aix75 and aging index were increased in the CoA group. Interestingly, in a subgroup analysis of CoA patients with tricuspid vs. bicuspid aortic valves (BAV), only the latter had increased Aix75. Carotid-femoral pulse wave velocity [cfPWV], reactive hyperemia index and microcirculation were not significantly different between CoA and control patients. Diastolic function was impaired in the CoA group relative to controls. Both diastolic function and age correlated moderate-strongly with arterial parameters. CONCLUSIONS Patients with well repaired CoA have increased proximal arterial stiffness which correlates with diastolic function and age. Increased Aix75 may be attributed to a high prevalence of associated BAV. Neither cfPWV nor peripheral endothelial or microcirculatory function are impaired.

Abstract
BACKGROUND After surgical repair of aortic coarctation (CoA) there is a risk for restenosis (reCoA), particularly in the first year of life. This study aimed to identify reCoA risk factors by analyzing postoperative predischarge echocardiograms. METHODS This was a retrospective analysis of echocardiograms of children born operated on for CoA in Sweden in 2011 to 2017. RESULTS A total of 253 children were included. Median age at surgery was 10 days; median follow-up was 4.6 years. Risk for restenosis occurred in 34 patients (13%; 74% by 6 months and 91% by 12 months). We generated 2 reCoA risk models applying aortic dimensions and the respective Z-scores combined with surgical and demographic factors. We defined reCoA risk categories as low (≤10%), moderate (11% to 29%), moderate to high (30% to 49%), or high (≥50%). Patients with either isthmus of 3.3 mm or less (1- and 5-year event-free survival of 38% and 32%, respectively) or isthmus Z-score of -2.8 or less with a weight at surgery of less than 4.4 kg (1- and 5-year event free survival of 21% and 16%, respectively) were at highest risk for reCoA. Conversely, patients at low risk had isthmus greater than 3.7 mm and distal aortic arch greater than 3.5mm (1- and 5-year event free survival of 97% and 97%, respectively), and isthmus and proximal aortic arch Z-score greater than -2.8 or operative weight greater than 4.4 kg with an isthmus Z-score of -2.8 or less (1- and 5-year event-free survival of 97% and 97%, respectively). CONCLUSIONS Risk for reCoA can be predicted based on postoperative predischarge echocardiographic variables combined with surgical and demographic factors. We suggest tailoring follow-up intervals individually according to the predicted reCoA risk.

Abstract
Establishing connections between changes in linear DNA sequences and complex downstream mesoscopic pathology remains a major challenge in biology. Herein, we report a novel, multi-modal and multiscale imaging approach for comprehensive assessment of cardiovascular physiology in Drosophila melanogaster We employed high-speed angiography, optical coherence tomography (OCT) and confocal microscopy to reveal functional and structural abnormalities in the hdp2 mutant, pre-pupal heart tube and aorta relative to controls. hdp2 harbor a mutation in wupA, which encodes an ortholog of human troponin I (TNNI3). TNNI3 variants frequently engender cardiomyopathy. We demonstrate that the hdp2 aortic and cardiac muscle walls are disrupted and that shorter sarcomeres are associated with smaller, stiffer aortas, which consequently result in increased flow and pulse wave velocities. The mutant hearts also displayed diastolic and latent systolic dysfunction. We conclude that hdp2 pre-pupal hearts are exposed to increased afterload due to aortic hypoplasia. This may in turn contribute to diastolic and subtle systolic dysfunction via vascular-heart tube interaction, which describes the effect of the arterial loading system on cardiac function. Ultimately, the cardiovascular pathophysiology caused by a point mutation in a sarcomeric protein demonstrates that complex and dynamic micro- and mesoscopic phenotypes can be mechanistically explained in a gene sequence- and molecular-specific manner.

Abstract
OBJECTIVE Trans-catheter (TC) pulmonary valve replacement (PVR) has become common practice for patients with right ventricular outflow tract obstruction (RVOTO) and/or pulmonic insufficiency (PI). Our aim was to compare PVR and right ventricular (RV) function of patients who received TC vs surgical PVR. DESIGN Retrospective review of echocardiograms obtained at three time points: before, immediately after PVR, and most recent. PATIENTS Sixty-two patients (median age 19 years, median follow-up 25 months) following TC (N = 32) or surgical (N = 30) PVR at Yale-New Haven Hospital were included. OUTCOME MEASURES Pulmonary valve and right ventricular function before, immediately after, and most recently after PVR. RESULTS At baseline, the TC group had predominant RVOTO (74% vs 10%, P < .001), and moderate-severe PI was less common (61% vs 100%, P < .001). Immediate post-procedural PVR function was good throughout. At last follow-up, the TC group had preserved valve function, but the surgical group did not (moderate RVOTO: 6% vs 41%, P < .001; >mild PI: 0% vs 24%, P = .003). Patients younger than 17 years at surgical PVR had the highest risk of developing PVR dysfunction, while PVR function in follow-up was similar in adults. Looking at RV size and function, both groups had a decline in RV size following PVR. However, while RV function remained stable in the TC group, there was a transient postoperative decline in the surgical group. CONCLUSIONS TC PVR in patients age <17 years is associated with better PVR function in follow-up compared to surgical valves. There was a transient decline in RV function following surgical but not TC PVR. TC PVR should therefore be the first choice in children who are considered for PVR, whenever possible.

Abstract
OBJECTIVE Determine prevalence and associations with pulmonary hypertension (PH) in preterm infants. STUDY DESIGN Prospective institutional echocardiographic PH screening at 36 to 38 weeks' corrected gestational age (GA) for infants born <32 weeks' GA who had bronchopulmonary dysplasia (BPD; group BPD), and infants without BPD who had a birth weight (BW) <750 g, or clinical suspicion for PH (group NoBPD). RESULTS Two hundred and four infants were screened (GA 25.9±2 weeks, BW 831±286 g). The PH prevalence in group BPD was higher than in group NoBPD (44/159 (28%) vs 5/45 (11%); P=0.028). In group BPD, BW and GA were lower in infants with PH compared with NoPH. Following correction for BW and GA, necrotizing enterocolitis (NEC), severe intraventricular hemorrhage (IVH), atrial septal defect (ASD), and mortality were independently associated with PH in infants with BPD. In group NoBPD, NEC was the only identified factor associated with PH. Altogether, screening only those infants with NEC and infants with BPD who also had a BW <840 g would have yielded a 84% sensitivity for detecting PH, and reduced the number of screening echocardiograms by 43%. CONCLUSIONS PH in prematurity is associated with NEC in infants with and without BPD. In infants with BPD, smaller GA and BW, severe IVH, ASD and mortality are also associated with PH. Infants without identified PH-associated factors may not require routine echocardiographic PH screening.

Abstract
BACKGROUND Pulmonary hypertension (PH) in infants with bronchopulmonary dysplasia (BPD) is associated with increased morbidity and mortality. Elevated levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and decreased levels of amino acid precursors of nitric oxide (NO) have been associated with PH, but have not been studied in infants with PH secondary to BPD. OBJECTIVE The aim of this study was to identify a biochemical marker for PH in infants with BPD. METHODS Twenty infants, born at <27 weeks' gestational age (GA) and/or with a birth weight (BW) ≤750 g, who met the criteria for BPD at 36 weeks' corrected GA (CGA) were enrolled in this cross-sectional pilot study. A screening echocardiogram was conducted at 36-38 weeks' CGA and plasma NT-proBNP and amino acid levels were obtained within 1 week of the screening echocardiogram. RESULTS Five infants (25%) had echocardiographic evidence of PH. GA and BW were not significantly different between the 2 groups (a PH group and a No PH group). NT-proBNP was significantly elevated in the PH group (median 1,650 vs. 520 pg/ml; p = 0.001) but citrulline levels were significantly lower (median 21 vs. 36 μmol/l; p = 0.005). Arginine levels were not significantly different between the groups (median 78 vs. 79 μmol/l; p = 1). CONCLUSION NT-proBNP and the NO precursor citrulline may be cost-effective biochemical markers for screening for the presence of PH in preterm infants who have BPD. If validated in a larger study, such biochemical markers may, in part, replace PH screening echocardiograms in these patients.

Abstract
Bicuspid aortic valve (BAV) is the most common congenital cardiac abnormality, occurring in 1% to 2% of the general population. Adults with degenerative aortic valve (AV) disease have been shown to have an elliptical shaped AV annulus. The goal of this study was to investigate the shape of the aortic annulus in children with BAV, coarctation of the aorta (CoA) with or without BAV, and normal controls with trileaflet AVs using 3-dimensional echocardiography (3DE). We reviewed echocardiograms of children with isolated BAV (n = 40), CoA (n = 26), and controls (n = 40) that included 3DE of the AV. Eccentricity index (EI) was defined as the ratio between the smaller and larger annular dimension. ΔD was defined as the difference between the larger and smaller annular dimension. Patients with BAV had an eccentric AV annulus compared with controls (BAV EI 0.85 ± 0.05 and control EI 0.96 ± 0.03; p <0.001). Subjects with CoA also had a more eccentric annulus than controls regardless of AV morphology (CoA 0.84 ± 0.06; p <0.001). EI was not associated with somatic growth parameters or gender. Among all patients with BAV, AV dysfunction was associated with fusion of the right and noncoronary (R-N) cusps (p <0.001), but there was no association between valve dysfunction and EI. ΔD was higher in both the BAV and CoA groups compared with the control group (BAV 3.4 ± 1.9 mm, CoA 2.8 ± 1.8 mm, and control 0.6 ± 0.4 mm; p <0.001 each). Although there was no significant correlation of ΔD with age in the control group during childhood, ΔD increased with age in the BAV and CoA groups. In conclusion, children with BAV and/or CoA have an elliptical shaped AV annulus by 3DE, which is independent of age, gender, or body surface area. AV annular eccentricity may lead to inaccurate measurement of AV annular size if measured by 2DE alone. Considering AV annular eccentricity when balloon sizing the annulus before valvuloplasty may help improve interventional results in some patients.

Abstract
BACKGROUND As the survival of children with cardiac disease increases, chronic complications of deep venous thrombosis from cardiac catheterization, particularly post-thrombotic syndrome, may be important to monitor for and treat, if needed. We aimed to determine the prevalence of this syndrome in children who underwent cardiac catheterization. PROCEDURE We conducted a cross-sectional study of children <18 years old at least 1 year from first catheterization through the femoral vein. We used the Manco-Johnson instrument, the only tool validated in children, to diagnose post-thrombotic syndrome. We defined the syndrome as a score ≥ 1. It was considered physically and functionally significant if the score was ≥ 1 in both physical and functional domains of the instrument. We also conducted ultrasonography to assess for thrombosis and valvular insufficiency. RESULTS We enrolled 62 children with a median age of 4 months during catheterization and a median of 5.4 years since catheterization. A total of 40 children had post-thrombotic syndrome (prevalence: 64.5%; 95% confidence interval: 51.3-76.3%), the majority of which were mild. Presence of cyanotic congenital heart disease, total number of catheterizations, use of antithrombotic agents at any time after the first catheterization, age at first catheterization, or time since first catheterization was not associated with the syndrome. A total of seven children (prevalence: 11.3%; 95% confidence interval: 3.2-19.4%) had physically and functionally significant syndrome. None of the children had abnormalities on ultrasonography at the time of enrollment. CONCLUSIONS Post-thrombotic syndrome is a common complication after cardiac catheterization. Manifestations are usually mild and unlikely to require treatment.

Abstract
AIMS Aortic stiffness and diastolic function are abnormal in adults with bicuspid aortic valves (BAVs). The goal of this study was to determine the relationship between aortic stiffness and left ventricular (LV) diastolic impairment in children with well-functioning BAV and no associated congenital heart disease. METHODS AND RESULTS This is a retrospective review of echocardiograms in children with isolated BAV (group BAV; N = 50) and healthy frequency-matched controls (group Control; N = 50). We analysed LV systolic and diastolic function, proximal and distal ascending aortic stiffness index (SI), distensibility, and strain. Age range was 0.2-20 (median 11) years. There was no significant difference in blood pressure, normalized LV size and systolic function between the groups. Several parameters of LV diastolic function were lower in group BAV compared with group Control (e.g. septal E': BAV 12 ± 2.3 cm/s; Control 13.5 ± 1.8 cm/s, P < 0.001). All parameters of proximal and distal ascending aortic elasticity were abnormal in group BAV vs. Control (SI proximal ascending aorta: BAV 4.2 ± 1.6; Control 3.0 ± 0.9, P < 0.001). There was no significant correlation between parameters of aortic elasticity and diastolic function. In a subgroup analysis of children with fusion of the right-non vs. right-left coronary cusps, there was no significant difference for any of the parameters analysed. CONCLUSION Even children with well-functioning isolated BAV have abnormalities in aortic elasticity and diastolic function when compared with the Control group. However, a relationship between the two could not be established.

Abstract
Aortic stiffness and diastolic function are abnormal in adults with repaired coarctation of the aorta (CoA). The goal of this study was to determine the relation between aortic stiffness and left ventricular (LV) diastolic impairment in children who had undergone CoA repair very early in life. This is a retrospective review of echocardiograms in children with isolated repaired CoA (group CoA; n = 24) and healthy matched controls (group Normal; n = 24). We analyzed systolic and LV diastolic functions, proximal and distal ascending aortic stiffness indices (SIs), distensibility, and strain. Age range was 0.3 to 21 (median 9) years. Age at time of CoA repair was 0 to 24 (median 0.5) months. Median time since CoA repair was 6 years. There was no significant difference in blood pressure, LV size, and systolic function between the groups. LV diastolic function was impaired in group CoA compared with group Normal (septal E': CoA 10.3 ± 1.6 cm/s and Normal 13.4 ± 1.9 cm/s, p <0.001). All parameters of proximal and distal ascending aortic elasticities were abnormal in group CoA versus Normal (SI of proximal ascending aorta: CoA 4.9 ± 1.6 and Normal 2.7 ± 0.6, p <0.001). Across all patients, there was a strong correlation between septal E' and proximal ascending aortic SI (r = -0.72, p <0.001). In conclusion, even children who underwent CoA repair at a very young age have abnormal LV diastolic function and aortic elasticity compared with controls and there is a linear relation between the 2. LV diastolic dysfunction in patients with repaired CoA may be due to chronically increased afterload.

Abstract
PURPOSE OF REVIEW As our understanding of the molecular regulation of cardiac development has progressed, an increasing number of genes that cause congenital heart disease when mutated are being identified. This review focuses on the progress made during the past year. RECENT FINDINGS After PTPN11 was identified as a Noonan syndrome disease gene, additional discoveries have made clear that mutations in other genes along the RAS signaling pathway can cause a spectrum of syndromes and possibly isolated congenital heart disease. Similarly, alterations of genes in other signaling and transcriptional pathways may contribute to the development of atrial septal defects and bicuspid aortic valves. Recently identified disease genes for syndromes associated with congenital heart disease are also reviewed. Finally, the possibility that somatic mosaicism may contribute to the development of congenital heart disease is discussed. SUMMARY The recent knowledge about the molecular genetic causes of congenital heart disease is reviewed. In many instances, these gene discoveries are being rapidly translated into meaningful genetic testing, which is improving the diagnosis and prognostication for congenital heart disease in isolation or in the context of a syndrome. Ultimately, genetic information will be necessary for planning care as well as clinical research.

Abstract
PTPN11 missense mutations cause approximately 50% of Noonan syndrome, an autosomal dominant disorder presenting with various congenital heart defects, most commonly valvar pulmonary stenosis, and hypertrophic cardiomyopathy. Atrioventricular septal defects and coarctation of the aorta occur in 15% and 9%, respectively. The aim of this study was to determine if PTPN11 mutations exist in non-syndromic patients with these two relevant forms of congenital heart disease. The 15 coding PTPN11 exons and their intron boundaries from subjects with atrioventricular septal defects (n = 24) and coarctation of the aorta (n = 157) were analyzed using denaturing high performance liquid chromatography and sequenced if abnormal. One subject with an atrioventricular septal defect but no other known medical problems had a c.127C > T transition in exon 2, predicting a p.L43F substitution. This mutation affected the phosphotyrosine-binding region in the N-terminal src homology 2 domain and was close to a Noonan syndrome mutation (p.T42A). An otherwise healthy patient with aortic coarctation had a silent c.540C > T change in exon 5 corresponding to p.D180D. Our study showed that PTPN11 mutations are rarely found in two isolated forms of congenital heart disease that commonly occur in Noonan syndrome. The p.L43F mutation belongs to a rare class of PTPN11 mutations altering the phosphotyrosine-binding region. These mutations are not predicted to alter the autoinhibition of the PTPN11 protein product, SHP-2, which is the mechanism for the vast majority of mutations causing Noonan syndrome. Future studies will be directed towards understanding these rare phosphotyrosine binding region mutants.

Abstract
To elucidate further the role, in normal development and in disease pathogenesis, of TFAP2B, a transcription factor expressed in neuroectoderm, we studied eight patients with Char syndrome and their families. Four novel mutations were identified, three residing in the basic domain, which is responsible for DNA binding, and a fourth affecting a conserved PY motif in the transactivation domain. Functional analyses of the four mutants disclosed that two, R225C and R225S, failed to bind target sequence in vitro and that all four had dominant negative effects when expressed in eukaryotic cells. Our present findings, combined with data about two previously identified TFAP2B mutations, show that dominant negative effects consistently appear to be involved in the etiology of Char syndrome. Affected individuals in the family with the PY motif mutation, P62R, had a high prevalence of patent ductus arteriosus but had only mild abnormalities of facial features and no apparent hand anomalies, a phenotype different from that associated with the five basic domain mutations. This genotype-phenotype correlation supports the existence of TFAP2 coactivators that have tissue specificity and are important for ductal development but less critical for craniofacial and limb development.
