BACKGROUND: The increased survival rate among individuals with CHD has sparked interest in their transition to adult healthcare. Although there is a general agreement on the importance of transition interventions, the empirical evidence supporting them is insufficient. Therefore, this study aimed to conduct a systematic review and meta-analysis of transition interventions for adult healthcare in adolescents and young adults.
RESULTS: A literature search was conducted for studies comparing the quantitative effects of transition interventions with control groups, published up to March 15, 2023, in major databases (CENTRAL, Embase, PubMed, Web of Science, CINAHL, KISS, and KMbase), major clinical trial registries, academic journal sites related to the topic, and grey literature databases. Ten studies involving a total of 1,297 participants were identified. Transition interventions proved effective in enhancing disease-related knowledge (Hedge\'s g = 0.89, 95% CI = 0.29-1.48) and self-management (Hedge\'s g = 0.67, 95% CI = 0.38-0.95), as well as reducing loss to follow-up (OR = 0.41, 95% CI = 0.22-0.77). The certainty of evidence for the estimated values of each major outcome was low or very low.
CONCLUSIONS: This study supports the implementation of transition interventions by demonstrating that they can improve patients\' disease knowledge and self-management, while also promoting treatment continuity. However, since the available data on transition interventions for adolescents and young adults with CHD remain limited, the widespread adoption of structured transition interventions in the future may alter the conclusions of this study.

BACKGROUND: Submaximal field walking tests are easy to apply and low cost, but it is necessary to standardize their application, especially in the pediatric population. The feasibility and its use in patients with congenital heart disease have been studied. To verify which are the submaximal field walking tests applied in the cardiopulmonary assessment of children and adolescents with CHD and to verify if they are being performed as recommended by the standardization protocols/guidelines.
METHODS: Literature review through a search in six electronic databases, structured in PICO format, without date restrictions. Looking for studies that used submaximal field walking tests in children and adolescents with congenital heart disease aged 5 to 18 years. Methodological quality, effectiveness and safety and risk of bias were assessed.
RESULTS: Five studies met the eligibility criteria with a sample of 160 individuals with congenital heart disease, and all used the six-minute walk test. Note that different methodologies and modifications are used. Only the clinical trial showed good methodological quality.Four studies had low risk of bias and one study had moderate risk.
CONCLUSIONS: Although the six-minute walk test is the only test used as a field test found in our research, there is no standardization in the application of the test, making it difficult to compare the results. In this sense, reducing the limitations and heterogeneity in the application of the test will enable more concrete outcomes and facilitate their reproduction in clinical practice.

Congenital Heart Disease (CHD) is a significant source of pediatric morbidity and mortality. As in other fields of medicine, studies have demonstrated racial and ethnic disparities in congenital heart disease outcomes. The cause of these outcome disparities is multifactorial, involving biological, behavioral, environmental, sociocultural, and systemic medical factors. Potential contributors include differences in preoperative illness severity secondary to coexisting medical conditions, differences in the rate of prenatal and early postnatal detection of CHD, and delayed access to care, as well as discrepancies in socioeconomic and insurance status, and systemic disparities in hospital care. Understanding the factors that contribute to these disparities is an essential step towards developing strategies to address them. As stewards of the perioperative surgical home, anesthesiologists have an important role in developing institutional policies that mitigate racial disparities. Here, we provide a thorough narrative review of recent research concerning perioperative factors contributing to surgical outcomes disparities for children of all ages with CHD, examine potentially modifiable contributing factors, discuss avenues for future research, and suggest strategies to address disparities both locally and nationally.

High-energy or high-protein feeding offers a promising approach to improving malnutrition in children after congenital heart surgery. However, the effect of high-energy or high-protein feeding in this population has not yet been systematically reviewed. Therefore, we aimed to assess the safety and effectiveness of high-energy or high-protein feeding in children after congenital heart surgery. Five electronic databases (PubMed, Embase, CENTRAL, CINAHL, and Scopus) were searched from inception to April 23, 2022. After screening the literature according to inclusion and exclusion criteria, a risk of bias assessment was performed using version 2 of the Cochrane risk-of-bias tool for randomized trials, and the certainty of the evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations system. Finally, the random effects model was used to perform a meta-analysis of all data. A total of 609 subjects from 9 studies were included for qualitative analysis, and meta-analyses were performed on data from 8 of these studies. The results showed that high-energy and/or high-protein feeding did not increase feeding intolerance (RR = 1.09, 95% CI: 0.80, 1.48) or fluid intake (MD =  - 12.50 ml/kg/d, 95% CI: - 36.10, 11.10); however, the intervention was beneficial in increasing weight (MD = 0.5 kg, 95% CI: 0.23, 0.77) and reducing the duration of mechanical ventilation (MD =  - 17.45 h, 95% CI: - 27.30, - 7.60), intensive care unit (ICU) stay (MD =  - 1.45 days, 95% CI: - 2.36, - 0.54) and hospital stay (MD =  - 2.82 days, 95% CI: - 5.22, - 0.43). However, high-energy and/or protein feeding did not reduce the infection rate (RR = 0.68, 95% CI: 0.25, 1.87) or mortality (RR = 1.50, 95% CI: 0.47, 4.82).
CONCLUSIONS: The certainty of the evidence was graded as moderate to high, which suggests that high-energy and/or high-protein feeding may be safe in children after congenital heart surgery. Furthermore, this intervention improves nutrition and reduces the duration of mechanical ventilation, length of ICU stay, and length of hospital stay. However, the overall conclusion of this meta-analysis will need to be confirmed in a cohort of patients with different cardiac physiologies.
BACKGROUND: • Malnutrition is highly prevalent in children with congenital heart disease (CHD) and can negatively affect the prognosis of these children. • High-energy and/or high-protein feeding can improve nutrition status and facilitate recovery; however, evidence on its safety and efficacy is lacking.
BACKGROUND: • Pooled data suggest that high-energy and/or high-protein feeding does not increase fluid intake or feeding intolerance in children with CHD. • High-energy and/or high-protein feeding may reduce the duration of mechanical ventilation, length of intensive care unit stay, and length of hospital stay.

Patients with CHD are less active if compared with controls and have limited functional capacity, related to muscle weakness and fatigue. The aim of this study was to evaluate the peripheral and respiratory muscle strength of children and adolescents with CHD with systematic review and meta-analysis. The review included observational and randomised control trial studies which evaluated peripheral and respiratory muscle strength in children and adolescents with CHD under 18 years old. The peripheral muscle strength was evaluated through dynamometry and respiratory muscle strength through manovacuometry. In studies that compared patients with CHD and respective control groups, it was possible to perform a meta-analysis. A total of 5634 articles met the criteria of eligibility, 15 were included in the systematic review, and 4 were included in the meta-analysis. Twelve studies assessed peripheral muscle strength with a reduction in patients with CHD. In the meta-analysis, patients with CHD had lower muscle strength than controls (-34.07 nm; 95% CI, -67.46 to -0.68; I2 47%; p for heterogeneity = 0.05), and the meta-analysis of the handgrip muscle strength showed no significant difference between patients with CHD and controls (0.08 nm; 95% CI, -6.39 to 6.55; I2 98%; p for heterogeneity <0.00001). The meta-analysis in the present study  showed lower limb muscle strength in patients with CHD in comparison to controls. In contrast, no difference was found regarding hand grip strength. Also, the review showed lower respiratory muscle strength in patients with CHD, yet no meta-analysis was possible to perform.

UNASSIGNED: Congenital heart disease (CHD) entails structural defects in the morphogenesis of the heart or its main vessels. Analyzing exercise capacity of children and adolescents with CHD is important to improve their functional condition and quality of life, since it can allow timely intervention on poor prognostic factors associated with higher risk of morbidity and mortality.
UNASSIGNED: To describe exercise capacity in children and adolescents with CHD compared with healthy controls.
UNASSIGNED: A systematic review was carried out. Randomized clinical trials and observational studies were included assessing exercise capacity through direct and indirect methods in children and adolescents between 5 and 17 years-old. A sensitive analysis was performed including studies with CHD repaired participants. Additionally, it was sub-analyzed by age range (< and ≥ 12 years old). Two independent reviewers analyzed the studies, extracted the data, and assessed the quality of the evidence.
UNASSIGNED: 5619 articles were found and 21 were considered for the review. Eighteen articles used the direct exercise capacity measurement method by cardiopulmonary exercise test (CPET). The CHD group showed significant differences in peak oxygen consumption (VO2peak) with a value of -7.9 ml/Kg/min (95% CI: -9.9, -5.9, p = 0.00001), maximum workload (Wmax) -41.5 (95% CI: -57.9, -25.1 watts, p = 0.00001), ventilatory equivalent (VE/VCO2 ) slope 2.6 (95% CI: 0.3, 4.8), oxygen pulse (O2 pulse)-2.4 ml/beat (95% CI: -3.7, -1.1, p = 0.0003), and maximum heart rate (HRmax) -15 bpm (95% CI: -18, -12 bpm, p = 0.00001), compared with healthy controls. Adolescents (≥ 12 yrs) with CHD had a greater reduction in VO2peak (-10.0 ml/Kg/min (95% CI: -12.0, -5.3), p < 0.00001), Wmax (-45.5 watts (95% CI: -54.4, -36.7), p < 0.00001) and HRmax (-21 bpm (95% CI: -28, -14), p<0.00001).
UNASSIGNED: Suffering CHD in childhood and adolescence is associated with lower exercise capacity as shown by worse VO2peak, Wmax, VE/VCO2 slope, O2 pulse, and HRmax compared with matched healthy controls. The reduction in exercise capacity was greater in adolescents.

Background: Infants with congenital heart disease (CHD) are at risk for feeding-related morbidity and mortality, with growth failure and oral feeding problems associated with poor outcomes. The benefits of human milk (HM) for preterm infants have been well documented, but evidence on HM for infants with CHD has recently begun to emerge. Objectives: Our primary aim was to examine the impact of HM feeding on outcomes for infants with CHD. Methods: Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines, a search was conducted using MEDLINE, CINAHL, and Cochrane Database of Systematic Reviews. The quality of each study was assessed using the Joanna Briggs Critical Appraisal Tools. A total of 16 studies were included. Results: There was evidence that an exclusive HM diet reduces the risk of necrotizing enterocolitis (NEC) for infants with CHD. Evidence with a higher risk for bias indicated that a well-managed HM diet may be associated with improved growth, shorter length of stay, and improved postoperative feeding and nutritional outcomes. Chylothorax outcomes were similar between modified HM and medium-chain triglyceride formula. The studies had significant limitations related to power, lack of control for covariates, and inconsistent delineation of feeding groups. Conclusions: Based on the reduced risk for NEC and given the conclusive benefits in other vulnerable populations, we recommend that clinicians and institutions prioritize programs to support HM feeding for infants with CHD. Large high-quality studies are needed to validate these results. Future work should clarify best practices in managing an HM diet to support optimal growth and development for these infants.

OBJECTIVE: Nickel allergy is common; endovascular specialists are often confronted with nickel allergic patients ahead of the implantation of endovascular devices, many of which are nickel-containing. Our aim was to elucidate whether nickel hypersensitivity is significantly associated with worse or adverse outcomes after placement of a nickel-containing endovascular device.
METHODS: Inclusion criteria were: endovascular and transcatheter procedures for coronary, structural heart, neurovascular and peripheral vascular pathology involving nickel-allergic patients. All adverse outcomes were included as defined by included studies. A systematic review and meta-analysis were undertaken using a random-effects model. Searches of MEDLINE and EMBASE were conducted for articles published 1947-2019.
RESULTS: 190 records were identified, 78 articles were included for qualitative synthesis and 15 met criteria for meta-analysis. Patch-test confirmed nickel allergy was associated with an increased risk of adverse outcomes following implantation of a nickel-containing endovascular device (n=14 articles, 1740 patients; OR 2.61, 95% CI 1.41 to 4.85). This finding further was observed in coronary (n=12 articles, 1624 patients; OR 1.94, 95% CI 1.16 to 3.23) and structural heart subgroups (n=2 articles, 83 patients; OR 52.28, 95% CI 1.31 to 2079.14), but not in the neurovascular subgroup (n=1 article, 33 patients; OR 3.04, 95% CI 0.59 to 15.72) or with a patient-reported history of nickel allergy (n=2 articles, 207 patients; OR 2.14, 95% CI 0.23 to 19.70).
CONCLUSIONS: Patch-tested nickel allergy is associated with an increased risk of adverse outcomes following endovascular device implantation and alternative treatment options should be considered. Specialists faced with patients\' self-reporting nickel allergy should consider proceeding to diagnostic patch-testing.

A patent foramen ovale (PFO) is an interatrial shunt, with a prevalence of 20-34% in the general population. While most people do not have secondary manifestations of a PFO, some reported sequelae include ischaemic stroke, migraine, platypnoea-orthodeoxia syndrome and decompression illness. Furthermore, in some cases, PFO closure should be considered for patients before neurosurgery and for patients with concomitant carcinoid syndrome. Recent trials support PFO closure for ischaemic stroke patients with high risk PFOs and absence of other identified stroke mechanisms. While PFOs can be associated with migraine with auras, with some patients reporting symptomatic improvement after closure, the evidence from randomised controlled trials is less clear in supporting the use of PFO closure for migraine treatment. PFO closure for other indications such as platypnoea-orthodeoxia syndrome, decompression illness and paradoxical embolism are based largely on case series with good clinical outcomes. PFO closure can be performed as a day surgical intervention with high procedural success and low risk of complications.

Device occlusion of perimembranous ventricular septal defect is gaining popularity with the emergence of newer, softer occluders and improved technical know-how. We report a 26-year-old lady with a moderate size perimembranous ventricular septal defect who had a new onset of bundle branch block shortly after device closure. The patient subsequently developed a complete atrio-ventricular heart block.
