RESUMO
BACKGROUND AND AIMS: Cardiopulmonary fitness in congenital heart disease (CHD) decreases faster than in the general population resulting in impaired health-related quality of life (HRQoL). As the standard of care seems insufficient to encourage and maintain fitness, an early hybrid cardiac rehabilitation programme could improve HRQoL in CHD. METHODS: The QUALIREHAB multicentre, randomized, controlled trial evaluated and implemented a 12-week centre- and home-based hybrid cardiac rehabilitation programme, including multidisciplinary care and physical activity sessions. Adolescent and young adult CHD patients with impaired cardiopulmonary fitness were randomly assigned to either the intervention (i.e. cardiac rehabilitation) or the standard of care. The primary outcome was the change in HRQoL from baseline to 12-month follow-up in an intention-to-treat analysis. The secondary outcomes were the change in cardiovascular parameters, cardiopulmonary fitness, and mental health. RESULTS: The expected number of 142 patients was enroled in the study (mean age 17.4 ± 3.4 years, 52% female). Patients assigned to the intervention had a significant positive change in HRQoL total score [mean difference 3.8; 95% confidence interval (CI) 0.2; 7.3; P = .038; effect size 0.34], body mass index [mean difference -0.7â kg/m2 (95% CI -1.3; -0.1); P = .022; effect size 0.41], level of physical activity [mean difference 2.5 (95% CI 0.1; 5); P = .044; effect size 0.39], and disease knowledge [mean difference 2.7 (95% CI 0.8; 4.6); P = .007; effect size 0.51]. The per-protocol analysis confirmed these results with a higher magnitude of differences. Acceptability, safety, and short-time effect of the intervention were good to excellent. CONCLUSIONS: This early hybrid cardiac rehabilitation programme improved HRQoL, body mass index, physical activity, and disease knowledge, in youth with CHD, opening up the possibility for the QUALIREHAB programme to be rolled out to the adult population of CHD and non-congenital cardiac disease.

BACKGROUND: Aerobic fitness is a predictor of cardiovascular health which correlates with health-related quality of life in the general population. The aim is to evaluate the aerobic capacity by cardiopulmonary exercise test (CPET) in children with sickle cell disease in comparison with healthy matched controls. METHODS: Controlled cross-sectional study. RESULTS: A total of 72 children (24 with sickle cell disease and 48 healthy controls), aged 6-17 years old were enrolled. Children with sickle cell disease had a poor aerobic capacity, with median VO2max Z-score values significantly lower than matched controls (-3.55[-4.68; -2.02] vs. 0.25[-0.22; 0.66], P < 0.01, respectively), and a high proportion of 92% children affected by an impaired aerobic capacity (VO2max Z-score < -1.64). The VO2max decrease was associated with the level of anemia, the existence of a homozygote HbS/S mutation, restrictive lung disease and health-related quality of life. CONCLUSION: Aerobic capacity is poor in children with sickle cell disease. VO2max decrease is associated with the level of anemia, the existence of a homozygote HbS/S mutation, lung function, and health-related quality of life. These results represent a signal in favor of early initiation of cardiac rehabilitation in patients with sickle cell disease. CLINICAL TRIALS: NCT05995743. IMPACT: Aerobic fitness is a predictor of cardiovascular health which correlates with health-related quality of life in the general population. Aerobic capacity (VO2max) is poor in children with sickle cell disease, despite the absence of any pattern of heart failure. VO2max decrease was associated with the level of anemia, the existence of a homozygote HbS/S mutation, restrictive lung disease, and health-related quality of life. These results are in favor of early initiation of cardiac rehabilitation in children with sickle cell disease.
RESUMO
PURPOSE: Childhood cancer survivors are at increased risk for cardiovascular disease. Maximal oxygen uptake (VO2max) is a major determinant of cardiovascular morbidity. The aim of this study was to compare aerobic capacity, measured by cardiopulmonary exercise test (CPET), of adolescents and young adults in remission with that of healthy controls and to identify the predictors of aerobic capacity in this population. METHOD: This is a controlled cross-sectional study. RESULTS: A total of 477 subjects (77 in remission and 400 controls), aged from 6 to 25 years, were included, with a mean delay between end of treatment and CPET of 2.9 ± 2.3 years in the remission group. In this group, the mean VO2max was significantly lower than in controls (37.3 ± 7.6 vs. 43.3 ± 13.1 mL/kg/min, P < 0.01, respectively), without any clinical or echocardiographic evidence of heart failure. The VAT was significantly lower in the remission group (26.9 ± 6.0 mL/kg/min vs. 31.0 ± 9.9 mL/kg/min, P < 0.01, respectively). A lower VO2max was associated with female sex, older age, higher BMI, radiotherapy, and hematopoietic stem cell transplantation. CONCLUSION: Impaired aerobic capacity had a higher prevalence in adolescents and young adults in cancer remission. This impairment was primarily related to physical deconditioning and not to heart failure. TRIAL REGISTRY: NCT04815447. IMPACT: In childhood cancer survivors, aerobic capacity is five times more impaired than in healthy subjects. This impairment mostly reflects early onset of physical deconditioning. No evidence of heart failure was observed in this population.

To identify the risk factors of early occurrence of malnutrition in infants with severe congenital heart disease (CHD) during their first year of life. Retrospective longitudinal multicenter study carried out from January 2014 to December 2020 in two tertiary care CHD centers. Four CHD hemodynamic groups were identified. Malnutrition was defined by a Waterlow score under 80% and/or underweight under -2 standard deviations. A total of 216 infants with a severe CHD, e.g., requiring cardiac surgery, cardiac catheterization, or hospitalization for heart failure during their first year of life, were included in the study. Malnutrition was observed among 43% of the cohort, with the highest prevalence in infants with increased pulmonary blood flow (71%) compared to the other hemodynamic groups (p < 0.001). In multivariate analysis, low birthweight (OR 0.62, 95% CI 0.44-0.89, p = 0.009), CHD with increased pulmonary blood flow (OR 4.80, 95% CI 1.42-16.20, p = 0.08), heart failure (OR 9.26, 95% CI 4.04-21.25, p < 0.001), and the number of hospitalizations (OR 1.35, 95% CI 1.08 l-1.69, p = 0.009) during the first year of life were associated with malnutrition (AUC 0.85, 95% CI 0.79-0.90). Conclusions: In infants with a severe CHD, early occurrence of malnutrition during the first year of life affected a high proportion of subjects. CHD with increased pulmonary blood flow, low birthweight, heart failure, and repeated hospitalizations were risk factors for malnutrition. Further studies are required to identify optimal nutritional support in this population. What is Known: ⢠Malnutrition is a known morbidity and mortality factor in children with severe congenital heart disease. What is New: ⢠Early occurrence of malnutrition during the first year of life in infant severe congenital heart disease (CHD) was high (43%). ⢠CHD with increased pulmonary blood flow, low birthweight, heart failure, and repeated hospitalizations during the first year of life were risk factors for malnutrition.

BACKGROUND: Participation in physical activity improves health in individuals with congenital heart disease. However, most do not sufficiently engage in physical activity. The aim of this study was to collect information regarding the experiences of adolescents with congenital heart disease who practiced physical activities. METHODS: French adolescents aged 13-18 years, diagnosed with congenital heart disease, class I or II dyspnoea on the NYHA scale and authorized physical activity were interviewed individually about their physical activity experiences using a semi-structured format. The qualitative interview transcript data were analysed using a phenomenological approach; data analysis was performed independently by three researchers and merged at each step until saturation. RESULTS: Eleven adolescents with congenital heart disease participated. Three main themes emerged: 'own representation', 'physical activity (PA) set-up' and 'environment'. Adolescents had a generally positive view of physical activity, which was associated with positive experiences. However, they reported that their physical condition limited PA, and they wished for adapted activities. The results revealed the importance of environmental factors, for example, within the social and school environments. The participants indicated that they appreciated the social interactions that PA afforded, but that integration into a group could be difficult, especially in school, with some participants describing feelings such as anxiety, frustration or guilt when they could not participate fully. PA facilitators included familial support. However, participants noted a lack of clear medical guidance to help them choose suitable activities based on their circumstances and personal preferences. They wished for the public to be better informed about congenital heart disease to reduce stigmatism. CONCLUSIONS: This study provides valuable information for clinicians, physical educators and policy makers to help them promote physical activity and support adolescents and their families in understanding their own condition, maximizing their potential and in their choice of activities.

AIMS: To estimate the effect of prophylactic angiotensin-converting enzyme inhibitors (ACEi) on survival in Duchenne muscular dystrophy (DMD). METHODS AND RESULTS: We analysed the data from the French multicentre DMD Heart Registry (ClinicalTrials.gov: NCT03443115). We estimated the association between the prophylactic prescription of ACEi and event-free survival in 668 patients aged 8 to 13 years, with normal left ventricular function, using (i) a Cox model with intervention as a time-dependent covariate, (ii) a propensity-based analysis comparing ACEi treatment vs. no treatment, and (iii) a set of sensitivity analyses. The study outcomes were overall survival and hospitalizations for heart failure (HF) or acute respiratory failure. Among the 668 patients included in the DMD Heart Registry, 576 (mean age 6.1 ± 2.8 years) were eligible for this study, of whom 390 were treated with ACEi prophylactically. Death occurred in 53 patients (13.5%) who were and 60 patients (32.3%) who were not treated prophylactically with ACEi, respectively. In a Cox model with intervention as a time-dependent variable, the hazard ratio (HR) associated with ACEi treatment was 0.49 [95% confidence interval (CI) 0.34-0.72] and 0.47 (95% CI 0.31-0.17) for overall mortality after adjustment for baseline variables. In the propensity-based analysis, 278 patients were included in the treatment group and 834 in the control group, with 18.5% and 30.4% 12-year estimated probability of death, respectively. ACEi were associated with a lower risk of death (HR 0.39; 95% CI 0.17-0.92) and hospitalization for HF (HR 0.16; 95% CI 0.04-0.62). All other sensitivity analyses yielded similar results. CONCLUSION: Prophylactic ACEi treatment in DMD was associated with a significantly higher overall survival and lower rates of hospitalization for HF.

BACKGROUND: The Pediatric Quality of Life Inventory Version 4.0 (PedsQLTM4.0) is a generic health-related quality of life (HRQoL) questionnaire, widely used in pediatric clinical trials but not yet validated in France. We performed the psychometric validation of the self and proxy PedsQLTM4.0 generic questionnaires for French children aged 8-12 years old. METHODS: This bicentric cross-sectional study included 123 children and their parents with congenital heart disease (CHD) and 97 controls. The psychometric validation method was based on the consensus-based standards for the selection of health measurement instruments (COSMIN). The reliability was tested using the intraclass correlation coefficient (ICC). To evaluate the validity of this scale, content, face, criterion, and construct validity psychometric proprieties were tested. Acceptability was studied regarding questionnaires' completion and the existence of a floor or a ceiling effect. RESULTS: Test-retest reliability intra-class correlation coefficients were mainly in good range (0.49-0.66). Face validity was very good among parents (0.85) and children (0.75). Content validity was good (0.70), despite misinterpretation of some items. In construct validity, each subscale had acceptable internal consistency reliability (Cronbach's α > 0.72 in self-reports, > 0.69 in proxy-reports). In the confirmatory factor analysis, the goodness-of-fit statistics rejected the original structure with 4 factors. The exploratory factor analysis revealed an alternative two-factor structure corresponding to physical and psychological dimensions. Convergent validity was supported by moderate (> 0.41) to high correlations (0.57) between PedsQL and Kidscreeen questionnaires for physical, emotion and school dimensions. The ability of the PedsQL to discriminate CHD severity was better with physical, social and total scores for both self-reports and proxy-reports. CONCLUSIONS: The PedsQLTM4.0 generic self and proxy HRQoL questionnaires found good psychometric properties, with regard to acceptability, responsiveness, validity, and reliability. This instrument appeared to be easy to use and comprehend within the target population of children aged 8 to 12 years old and their parents. TRIAL REGISTRATION: This study was approved by the South-Mediterranean-IV Ethics Committee and registered on ClinicalTrials.gov (NCT01202916), https://clinicaltrials.gov/ct2/show/NCT01202916 .

BACKGROUND: Recent advances in the field of congenital heart disease (CHD) led to an improved prognosis of the patients and in consequence the growth of a new population: the grown up with congenital heart disease. Until recently, more than 50% of these patients were lost to follow up because of the lack of specialized structures. The critical moment is the transition between paediatric and adult unit. Therapeutic education is crucial to solve this issue by helping patients to become independent and responsible. The TRANSITION-CHD randomized trial aims to assess the impact of a transition education program on health-related quality of life (HRQoL) of adolescents and young adults with CHD. METHODS: Multicentre, randomised, controlled, parallel arm study in CHD patients aged from 13 to 25 years old. Patients will be randomised into 2 groups (education program vs. no intervention). The primary outcome is the change in self-reported HRQoL between baseline and 12-month follow-up. A total of 100 patients in each group is required to observe a significant increase of the overall HRQoL score of 7 ± 13.5 points (on 100) with a power of 80% and an alpha risk of 5%. The secondary outcomes are: clinical outcomes, cardiopulmonary exercise test parameters (peak VO2, VAT, VE/VCO2 slope), level of knowledge of the disease using the Leuven knowledge questionnaire for CHD, physical and psychological status. DISCUSSION: As the current research is opening on patient related outcomes, and as the level of proof in therapeutic education is still low, we sought to assess the efficacy of a therapeutic education program on HRQoL of CHD patients with a randomized trial. TRIAL REGISTRATION: This study was approved by the National Ethics Committee (South-Mediterranean IV 2016-A01681-50) and was registered on Clinicaltrials.gov (NCT03005626).

BACKGROUND: Advances in paediatric cardiology have improved the prognosis of children with inherited cardiac disorders. However, health-related quality of life (QoL) and physical activity have been scarcely analysed in children with inherited cardiac arrhythmia or inherited cardiomyopathy. Moreover, current guidelines on the eligibility of young athletes with inherited cardiac disorders for sports participation mainly rely on expert opinions and remain controversial. METHODS: The QUALIMYORYTHM trial is a multicentre observational controlled study. The main objective is to compare the QoL of children aged 6 to 17 years old with inherited cardiac arrhythmia (long QT syndrome, Brugada syndrome, catecholaminergic polymorphic ventricular tachycardia, or arrhythmogenic right ventricular dysplasia), or inherited cardiomyopathy (hypertrophic, dilated, or restrictive cardiomyopathy), to that of age and gender-matched healthy subjects. The secondary objective is to assess their QoL according to the disease's clinical and genetic characteristics, the level of physical activity and motivation for sports, the exercise capacity, and the socio-demographic data. Participants will wear a fitness tracker (ActiGraph GT3X accelerometer) for 2 weeks. A total of 214 children are required to observe a significant difference of 7 ± 15 points in the PedsQL, with a power of 90% and an alpha risk of 5%. DISCUSSION: After focusing on the survival in children with inherited cardiac disorders, current research is expanding to patient-reported outcomes and secondary prevention. The QUALIMYORYTHM trial intends to improve the level of evidence for future guidelines on sports eligibility in this population.

BACKGROUND: In the context of tremendous progress in congenital cardiology, more attention has been given to patient-related outcomes, especially in assessing health-related quality of life (HRQoL) of patients with congenital heart diseases (CHD). However, most studies have mainly focused on teenagers or adults and currently, few HRQoL controlled data is available in young children. This study aimed to evaluate HRQoL of children with CHD aged 5 to 7 y.o., in comparison with contemporary peers recruited in school, as well as the factors associated with HRQoL in this population. METHODS: This multicentre controlled prospective cross-sectional study included 124 children with a CHD (mean age = 6.0 ± 0.8 y, 45% female) during their outpatient visit and 125 controls (mean age = 6.2 ± 0.8 y, 54% female) recruited at school. A generic paediatric HRQoL instrument was used (PedsQL 4.0). RESULTS: Self-reported HRQoL in children with CHD was similar to controls, overall (73.5 ± 1.2 vs. 72.8 ± 1.2, P = 0.7, respectively), and for each dimension. Parents-reported HRQoL was significantly lower in the CHD group than in controls. HRQoL was predicted by the disease severity and by repeated invasive cardiac procedures (surgery or catheterization). CONCLUSION: HRQoL in young children with CHD aged 5 to 7 years old was good and similar to controls. This study contributed to the growing body of knowledge on HRQoL in congenital cardiology and emphasized the need for child and family support in the most complex CHD. Trial registration This study was approved by the institutional review board of Montpellier University Hospital (2019_IRB-MTP_02-19) on 22 February 2019 and was registered on ClinicalTrials.gov (NCT03931096) on 30 April 2019, https://clinicaltrials.gov/ct2/show/NCT03931096 .

Background: Fabry disease (FD) is a rare X-linked lysosomal disorder caused by pathogenic variants in the alpha-galactosidase-A gene (GLA). Life threatening complications in adulthood include chronic kidney failure, strokes and the cardiac involvement which is the leading cause of mortality. Usually, it presents with hypertrophic cardiomyopathy, together with arrhythmia and conduction abnormalities. An early indicator is decreased T1 value on cardiac magnetic resonance (CMR). Enzyme replacement therapy (ERT) is effective on some extra-cardiac symptoms but its effect on cardiac lesions depends on the level of initial myocardial lesions. CMR is routinely used to monitor cardiac involvement in FD due to its capacity for tissular characterization. However, there is a lack of data on the pediatric population to understand how to integrate CMR into early therapeutic decisions. Method: Monocentric longitudinal study carried out at Montpellier University Hospital from 2016 to 2022. All pediatric patients with FD were evaluated over time with clinical, biological, and cardiac imaging (CMR, echocardiography). Results: Out of the six patients included, (3 males), five were treated with ERT during the study. Low T1 values were observed in 4 patients. The normalization of T1 values was observed after 4 years of ERT in 3 patients. Conclusion: Due to the lack of strong clinical and biological markers of FD in pediatric patients, initiation and follow-up of ERT efficacy remain challenging. CMR with T1-mapping, a noninvasive method, could play a role in the evaluation of early cardiac impairment in young patients at diagnosis and during follow-up with or without ERT.
RESUMO
BACKGROUND: To assess the feasibility, acceptability, safety, and short-term benefits of a tailored cardiac rehabilitation program for children and adolescents with long QT syndrome (LQTS). METHODS: Eight participants, aged between 6 and 18, with a positive LQTS genotype and impaired cardiorespiratory fitness, were enrolled in a 12-week centre-based cardiac rehabilitation program. The program included supervised exercise training group sessions (aerobic, resistance, and outdoor activities) and patient education workshops. Feasibility, acceptability, and safety of the program were prospectively monitored. Feedback from the parents, children, and professionals involved was collected from qualitative interviews. Short-term effects on cardiorespiratory fitness, muscle fitness, physical activity, and health-related quality of life (HRQoL) were measured between baseline and the end of the program. RESULTS: Retention (88% with one participant dropping out) and adherence (79%) rates were good, and no cardiac events occurred during the 12-week intervention period. Participants, parents, and healthcare professionals expressed a high level of satisfaction with the program. A significant increase between the beginning and the end of the program was observed for ventilatory anaerobic threshold (21.7±5.2 vs. 28.7±5.1 mL/kg/min, P=0.01, effect size=0.89), grip strength, (18±5.3 Kg vs. 20±4.7 Kg, P=0.02, effect size=0.90), lower limb explosive strength (142±36.5 cm vs. 148±24 cm, P=0.02, effect size=0.90), and parent-reported physical health dimension of HRQoL (65.6±9.75 vs. 84.4±20.35, P=0.03, effect size=0.87). CONCLUSIONS: A 12-week tailored centre-based cardiac rehabilitation program was feasible, acceptable, and safe for children with LQTS. Cardiac rehabilitation for children with LQTS presents a new approach aligned with secondary prevention in youth with cardiac diseases. TRIAL REGISTRATION: The trial was registered at Clinicaltrials.gov (NCT05964322, registration date: 27/07/2023).
RESUMO
OBJECTIVES: This study aims to describe the various presentations of the prenatally diagnosed isolated right aortic arch (RAA), that is, without associated congenital heart defect and to evaluate the impact of prenatal diagnosis of isolated RAA in terms of postnatal outcome. METHOD: In this multicentric retrospective study, from 2010 to 2019, all live births with a prenatal ultrasound diagnosis of isolated RAA were included, with a 1-year postnatal follow-up. The concordance between the different diagnostic steps (prenatal ultrasound, postnatal ultrasound and postnatal CT scan) was evaluated using Gwet's AC1 coefficient. RESULTS: A total of 309 cases of prenatally diagnosed RAA were analysed, most of which had a left ductus arteriosus (83%). The concordance between prenatal and postnatal ultrasound diagnosis was excellent regarding the RAA type (AC1=0.97, 95% CI=(0.94 to 0.99)). The rare discrepancies mainly involved non-diagnosed or misdiagnosed double aortic arch (2%). CT scan was performed in 108 neonates (35%) and the concordance between prenatal ultrasound and postnatal CT scan was good regarding the RAA diagnosis (AC1=0.80, 95% CI=(0.69 to 0.90)) but poor regarding the distribution of brachiocephalic vessels (AC1=0.21, 95% CI=(0.06 to 0.36)). An associated genetic anomaly was sought for in half of the cases and identified in 4% of the cohort. During the first year of life, 50 (18%) infants presented with vascular ring symptoms and 24 (8%) underwent aortic arch surgery. CONCLUSION: This multicentric nationwide cohort of 309 prenatally diagnosed isolated RAA demonstrated the reliability of prenatal screening, highlighted the rare cases of discrepancies between prenatal and postnatal diagnosis and underlined the value of CT scan to improve the postnatal follow-up. TRIAL REGISTRATION NUMBER: NCT04029064.
RESUMO
PURPOSE: Currently, nearly 90% of patients with congenital heart disease (CHD) reach adulthood in relatively good health. Structured transition programs have emerged to support adolescents and young adults in transitioning to adult care structures, improve their autonomy, and limit healthcare ruptures. The TRANSITION-CHD randomized controlled trial aimed to assess the impact of a transition program on health-related quality of life (HRQoL) in adolescents and young adults with CHD. METHODS: From January 2017 to February 2020, 200 subjects with a CHD, aged 13-25 years, were enrolled in a prospective, controlled, multicenter study and randomized in two balanced groups (transition program vs. standard of care). The primary outcome was the change in PedsQL self-reported HRQoL score between baseline and 12-month follow-up, using an intention-to-treat analysis. The secondary outcomes were the change in disease knowledge, physical health (cardiopulmonary fitness, physical activity), and mental health (anxiety, depression). RESULTS: The change in HRQoL differed significantly between the transition group and the control group (mean difference = 3.03, 95% confidence interval (CI) = [0.08; 5.98]; p = .044; effect size = 0.30), in favor of the intervention group. A significant increase was also observed in the self-reported psychosocial HRQoL (mean difference = 3.33, 95% CI = [0.01; 6.64]; p = .049; effect size = 0.29), in the proxy-reported physical HRQoL (mean difference = 9.18, 95% CI = [1.86; 16.51]; p = .015; effect size = 0.53), and in disease knowledge (mean difference = 3.13, 95% CI = [1.54; 4.72]; p < .001; effect size = 0.64). DISCUSSION: The TRANSITION-CHD program improved HRQoL and disease knowledge in adolescents and young adults with CHD, supporting the generalization and systematization of similar preventive interventions in pediatric and congenital cardiology.

BACKGROUND: The origin of congenital or childhood nonimmune isolated atrioventricular (AV) block remains unknown. We hypothesized that this conduction abnormality in the young may be a heritable disease. METHODS AND RESULTS: A multicenter retrospective study (13 French referral centers, from 1980-2009) included 141 children with AV block diagnosed in utero, at birth, or before 15 years of age without structural heart abnormalities and without maternal antibodies. Parents and matched control subjects were investigated for family history and for ECG screening. In parents, a family history of sudden death or progressive cardiac conduction defect was found in 1.4% and 11.1%, respectively. Screening ECGs from 130 parents (mean age 42.0 ± 6.8 years, 57 couples) were compared with those of 130 matched healthy control subjects. All parents were asymptomatic and in sinus rhythm, except for 1 with undetected complete AV block. Conduction abnormalities were more frequent in parents than in control subjects, found in 50.8% versus 4.6%, respectively (P<0.001). A long PR interval was found in 18.5% of the parents but never in control subjects (P<0.0001). Complete or incomplete right bundle-branch block was observed in 39.2% of the parents and 1.5% of the control subjects (P<0.0001). Complete or incomplete left bundle-branch block was found in 15.4% of the parents and 3.1% of the control subjects (P<0.0006). Estimated heritability for isolated conduction disturbances was 91% (95% confidence interval, 80%-100%). SCN5A mutation screening identified 2 mutations in 2 patients among 97 children. CONCLUSIONS: ECG screening in parents of children affected by idiopathic AV block revealed a high prevalence of conduction abnormalities. These results support the hypothesis of an inheritable trait in congenital and childhood nonimmune isolated AV block.

AIMS: The natural history of congenital or childhood non-immune, isolated atrioventricular (AV) block is poorly defined. METHODS AND RESULTS: We retrospectively studied 141 children with isolated, non-immune AV block diagnosed in utero, or up to 15 years of age, at 13 French medical centres, between 1980 and 2009. Patients with structural heart disease or maternal antibodies were excluded. Atrioventricular block was asymptomatic in 119 (84.4%) and complete in 100 (70.9%) patients. There was progression to complete AV block in 29/41 (70.7%) patients with incomplete AV block over 2.8 ± 3.4 years (1-155 months), but all patients with incomplete AV block may not have been included in the study. Narrow QRS complex was present in 18 of 26 patients (69.2%) with congenital, and 106 of 115 (92.2%) with childhood AV block. Pacemakers were implanted in 112 children (79.4%), during the first year of life in 18 (16.1%) and before 10 years of age in 90 (80.4%). The mean interval between diagnosis of AV block and pacemaker implants was 2.6 ± 3.9 years (0-300 months). The pacing indication was prophylactic in 70 children (62.5%). During a mean follow-up of 11.6 ± 6.7 years (1-32 years), no patient died or developed dilated cardiomyopathy (DCM). The long-term follow-up was uncomplicated in 127 children (90.1%). CONCLUSION: In this large multicentre study, the long-term outcome of congenital or childhood non-immune, isolated AV block was favourable, regardless of the patient's age at the time of diagnosis. No patient died or developed DCM, and pacemaker-related complications were few.

A 1-day-old girl was referred for a cardiology consultation for a mean saturation at 80% without respiratory distress. Echocardiography showed an isolated ventricular inversion. This entity is extremely rare, with fewer than 20 cases reported. This case report describes the clinical evolution and the complex surgical management of this pathology. (Level of Difficulty: Advanced.).
RESUMO
Background: Kawasaki disease (KD) is a rare paediatric condition that can lead to giant coronary aneurysms. Follow-up of such complex coronary lesions remains a challenge, and their management is difficult to standardize. Case summary: Our present case concerns a 17-year-old boy who suffered a giant aneurysm of the left coronary artery, complicated by an asymptomatic stenosis. During regular follow-up, his annual cardiopulmonary exercise test revealed signs of ischaemia (ST depression and premature ventricular complexes). After several further stress tests with inconsistent results, he underwent invasive coronary angiography that revealed significant stenosis with a positive fractional flow reserve (FFR). Discussion: We discuss the challenges of diagnosing and managing coronary artery stenosis in paediatric patients with KD, particularly in cases with calcified and thrombosed lesions. A multimodal approach is crucial, including non-invasive imaging, and coronary angiography with optical coherence tomography and FFR. The evaluation of the lesion and its follow-up is an important factor in anticipating the best therapeutic choice for each patient.
RESUMO
AIMS: Overweight and obesity in children with congenital heart disease (CHD) represent an alarming cardiovascular risk. Promotion of physical activity and cardiac rehabilitation in this population requires assessing the level of aerobic fitness (VO2max) by a cardiopulmonary exercise test (CPET). Nevertheless, the interpretation of CPET in overweight/obese children with CHD remains challenging as VO2max is affected by both the cardiac condition and the body mass index (BMI). The new paediatric VO2max Z-score reference equations, based on a logarithmic function of VO2max, height and BMI, were applied to overweight/obese children with a CHD and compared with overweight/obese children without any other chronic condition. METHODS AND RESULTS: In this cross-sectional controlled study, 344 children with a BMI > 85th percentile underwent a CPET (54% boys; mean age 11.5 ± 3.1 years; 100 CHD; 244 controls). Using the VO2max Z-score equations, aerobic fitness was significantly lower in obese/overweight CHD children than that in matched obese/overweight control children (-0.43 ± 1.27 vs. -0.01 ± 1.09; P = 0.02, respectively), and the proportion of children with impaired aerobic fitness was significantly more important in obese/overweight CHD children than in matched controls (17% vs.6%, P = 0.02, respectively). The paediatric VO2max Z-score reference equations also identified specific complex CHD at risk of aerobic fitness impairment (univentricular heart and right outflow tract anomalies). Using Cooper's weight- and height-based linear equations, similar matched-comparisons analyses found no significant group differences. CONCLUSIONS: As opposed to the existing linear models, the new paediatric VO2max Z-score equations can discriminate the aerobic fitness of obese/overweight children with CHD from that of obese/overweight children without any chronic disease. REGISTRATION: ClinicalTrials.gov NCT04815577.
The new paediatric VO2max Z-score reference equations found a lower aerobic fitness in obese or overweight children with CHD than that in matched obese or overweight control children and a high proportion of children with impaired aerobic fitness in obese or overweight children with CHD and identified specific complex CHD at risk of aerobic fitness impairment. As opposed to Cooper's weight-based or height-based linear equations, the new paediatric VO2max Z-score equations can discriminate the aerobic fitness of obese or overweight children with CHD from that of obese or overweight children without any chronic disease.

BACKGROUND: To evaluate the change in aerobic fitness (VO2max), measured by cardio-pulmonary exercise test (CPET), in children with congenital heart disease (CHD), compared to matched healthy controls, and identify predictors of VO2max change with time in this specific population. METHOD: This longitudinal retrospective multicentre cohort study was carried out from 2010 to 2020. We included CHD paediatric patients from the cohort of a previous cross-sectional study, who had a second CPET at least 1 year after the first one, during their follow-up. RESULTS: We included 936 children, 296 in the CHD group and 640 controls. Mean time between baseline and final CPET was 4.4 ± 1.7 years. After matching on age and gender and adjustment for age and BMI, the mean VO2max group difference was 10.5% ± 1.0% of percent-predict VO2max at baseline and increased to 19.1% ± 1.3% at final assessment. In the CHD group, the proportion of children with impaired aerobic fitness was significantly higher at final than at baseline CPET assessment (51.4% vs 20.3%; P < 0.01). The mean annual VO2max decrease was significantly worse in the CHD group than in controls (-1.88% ± 0.19% of percent-predict VO2max/year vs. -0.44% ± 0.27% of percent-predict VO2max/year, P < 0.01, respectively). In multivariate analyse, male gender, a high initial VO2max, a high BMI, and the number of cardiac surgical procedures ≥2, were predictors of the VO2max decrease with time. CONCLUSION: The VO2max decrease with time is more pronounced in children with CHD compared to healthy matched controls. This study highlighted the importance of serial CPET assessment in children with CHD. Trial registration NCT04815577.
