ABSTRACT

Importance: Obesity may affect the clinical course of Kawasaki disease (KD) in children and multisystem inflammatory syndrome in children (MIS-C) associated with COVID-19. Objective: To compare the prevalence of obesity and associations with clinical outcomes in patients with KD or MIS-C. Design, Setting, and Participants: In this cohort study, analysis of International Kawasaki Disease Registry (IKDR) data on contemporaneous patients was conducted between January 1, 2020, and July 31, 2022 (42 sites, 8 countries). Patients with MIS-C (defined by Centers for Disease Control and Prevention criteria) and patients with KD (defined by American Heart Association criteria) were included. Patients with KD who had evidence of a recent COVID-19 infection or missing or unknown COVID-19 status were excluded. Main Outcomes and Measures: Patient demographic characteristics, clinical features, disease course, and outcome variables were collected from the IKDR data set. Using body mass index (BMI)/weight z score percentile equivalents, patient weight was categorized as normal weight (BMI <85th percentile), overweight (BMI ≥85th to <95th percentile), and obese (BMI ≥95th percentile). The association between adiposity category and clinical features and outcomes was determined separately for KD and MIS-C patient groups. Results: Of 1767 children, 338 with KD (median age, 2.5 [IQR, 1.2-5.0] years; 60.4% male) and 1429 with MIS-C (median age, 8.7 [IQR, 5.3-12.4] years; 61.4% male) were contemporaneously included in the study. For patients with MIS-C vs KD, the prevalence of overweight (17.1% vs 11.5%) and obesity (23.7% vs 11.5%) was significantly higher (P < .001), with significantly higher adiposity z scores, even after adjustment for age, sex, and race and ethnicity. For patients with KD, apart from intensive care unit admission rate, adiposity category was not associated with laboratory test features or outcomes. For patients with MIS-C, higher adiposity category was associated with worse laboratory test values and outcomes, including a greater likelihood of shock, intensive care unit admission and inotrope requirement, and increased inflammatory markers, creatinine levels, and alanine aminotransferase levels. Adiposity category was not associated with coronary artery abnormalities for either MIS-C or KD. Conclusions and Relevance: In this international cohort study, obesity was more prevalent for patients with MIS-C vs KD, and associated with more severe presentation, laboratory test features, and outcomes. These findings suggest that obesity as a comorbid factor should be considered at the clinical presentation in children with MIS-C.

ABSTRACT

Pulse wave velocity (PWV) has been explored to predict cardiovascular health in adults. Less is known about neonatal PWV. We evaluated the association between arterial stiffness of neonates of mothers (NoM) with diabetes and childhood health. Neonatal brachial-femoral PWV (bfPWV) was measured after birth and neonates followed for a median of 5.2 years [1 month-6.6 years]. 36 pregnant women with pregestational diabetes mellitus PGDM (n = 12), gestational diabetes mellitus (GDM) (n = 13), and controls (n = 11) were enrolled. Neonates were similar in weight, gestational age, and delivery mode. 26 neonates had follow-up data including weight, height and blood pressure. More mothers with PGDM had poor glycemic control compared to mothers with GDM (83% vs. 8%; p = 0.0002). PWV was higher in NoM with PGDM than controls (3.4 ± 0.5 vs. 2.6 ± 0.8 m/s; p = 0.04). At follow-up, children of mothers with diabetes (n = 16) had higher weight percentile (78.5 ± 27.9 vs 49.5 ± 34.6%; p = 0.02) and diastolic blood pressure (DBP) (68 ± 13.6 vs 57.3 ± 4.3 mmHg; p = 0.01) than controls (n = 10). No correlation emerged between neonatal PWV and childhood body mass index (BMI) or maternal HbA1c. Results suggest maternal diabetes affect neonatal arterial stiffness and childhood blood pressure; however, the mechanism is unclear. The long-term implications of these findings warrant further investigation.

ABSTRACT

In this manuscript, we describe the design and rationale of a randomized controlled trial in pediatric Fontan patients to test the hypothesis that a live-video-supervised exercise (aerobic+resistance) intervention will improve cardiac and physical capacity; muscle mass, strength, and function; and endothelial function. Survival of children with single ventricles beyond the neonatal period has increased dramatically with the staged Fontan palliation. Yet, long-term morbidity remains high. By age 40, 50% of Fontan patients will have died or undergone heart transplantation. Factors that contribute to onset and progression of heart failure in Fontan patients remain incompletely understood. However, it is established that Fontan patients have poor exercise capacity which is associated with a greater risk of morbidity and mortality. Furthermore, decreased muscle mass, abnormal muscle function, and endothelial dysfunction in this patient population is known to contribute to disease progression. In adult patients with 2 ventricles and heart failure, reduced exercise capacity, muscle mass, and muscle strength are powerful predictors of poor outcomes, and exercise interventions can not only improve exercise capacity and muscle mass, but also reverse endothelial dysfunction. Despite these known benefits of exercise, pediatric Fontan patients do not exercise routinely due to their chronic condition, perceived restrictions to exercise, and parental overprotection. Limited exercise interventions in children with congenital heart disease have demonstrated that exercise is safe and effective; however, these studies have been conducted in small, heterogeneous groups, and most had few Fontan patients. Critically, adherence is a major limitation in pediatric exercise interventions delivered on-site, with adherence rates as low as 10%, due to distance from site, transportation difficulties, and missed school or workdays. To overcome these challenges, we utilize live-video conferencing to deliver the supervised exercise sessions. Our multidisciplinary team of experts will assess the effectiveness of a live-video-supervised exercise intervention, rigorously designed to maximize adherence, and improve key and novel measures of health in pediatric Fontan patients associated with poor long-term outcomes. Our ultimate goal is the translation of this model to clinical application as an "exercise prescription" to intervene early in pediatric Fontan patients and decrease long-term morbidity and mortality.

ABSTRACT

BACKGROUND: Intraoperative imaging determines the integrity of surgical repairs. Transoesophageal echocardiography represents standard care for intraoperative imaging in CHD. However, some conditions preclude its use, and epicardial echocardiography is used alternatively. Minimal literature exists on the impact of epicardial echocardiography versus transoesophageal echocardiography. We aimed to evaluate accuracy between the two modalities and hypothesised higher imaging error rates for epicardial echocardiography. METHODS: We retrospectively reviewed all epicardial echocardiograms performed over 16 years and compared them to an age- and procedure-matched, randomly selected transoesophageal echocardiography cohort. We detected un- or misidentified cardiac lesions during the intraoperative imaging and evaluated patient outcomes. Data are presented as a median with a range, or a number with percentages, with comparisons by Wilcoxon two-sample test and Fisher's exact test. RESULTS: Totally, 413 patients comprised the epicardial echocardiography group with 295 transoesophageal echocardiography matches. Rates of imaging discrepancies, re-operation, and incision infection were similar. About 13% of epicardial echocardiography patients had imaging discrepancies versus 16% for transoesophageal (p = 0.2352), the former also had smaller body sizes (p < 0.0001) and more genetic abnormalities (33% versus 19%, p < 0.0001). Death/mechanical support occurred more frequently in epicardial echocardiography patients (16% versus 6%, p < 0.0001), while hospitalisations were longer (25 versus 19 days, p = 0.0003). CONCLUSIONS: Diagnostic accuracy was similar between patients undergoing epicardial echocardiography and transoesophageal echocardiography, while rates of death and mechanical support were increased in this inherently higher risk patient population. Epicardial echocardiography provides a reasonable alternative when transoesophageal echocardiography is not feasible.

ABSTRACT

Recommendations for management of patients with Kawasaki disease (KD) and coronary artery aneurysms (CAA) include physical activity (PA) promotion. This study aimed to characterize self-reported practices of KD providers to evaluate practice variation in use of cardiopulmonary exercise testing (CPET) and PA recommendations. We developed a REDCap survey with different clinical scenarios of KD patients. It was completed by members of the International Kawasaki Disease Registry (IKDR) and community pediatric cardiologists. Twenty-eight physicians responded; 63% practiced in the US, 63% practiced in an academic setting, 48% were general pediatric cardiologists, and 55% were IKDR members. Most respondents (69%) followed < 50 KD patients. The great majority (93%) agreed that patients with no CAA do not require CPET and could be cleared for all PA. For patients with small CAA, 43% of respondents recommended CPET and 75% cleared for all PA if CAAs regressed completely, but only 32% cleared if CAA persisted. For patients with medium CAA, 66% respondents cleared for PA if CAA regressed, and only 7% if CAA persisted; with 66% and 75% recommending CPET, respectively. For patients with large/giant CAA, 81% of respondents recommended CPET. No respondents felt comfortable clearing their patients with persistent large/giant CAA for PA and 19% would restrict from the entire physical education program. There is practice variation in use of CPET in KD patients with CAAs. Providers are hesitant to promote PA in KD patients with CAA despite known benefits and current guidelines.

ABSTRACT

BACKGROUND: Echocardiographic quantification of fetal cardiac output (CO) aids clinical decision-making in the management of various cardiac and extracardiac diseases. Small variability in measuring semilunar valve dimension significantly reduces the reproducibility of the calculated CO. The authors propose minute stroke distance or velocity-time integral (VTI) as a more reproducible measure reflecting fetal ventricular systolic function. The aim of this study was to test the hypothesis that right and left ventricular minute VTI increase predictably with estimated fetal weight and are more reproducible than CO. METHODS: Five hundred seventy-one singleton fetuses without cardiovascular pathology between 16 and 36 weeks' gestation were reviewed retrospectively. Twenty-two fetuses with pathology resulting in low- or high-CO states were also assessed for comparison. VTI was measured in both ventricular outflow tracts at the level of the semilunar valve, excluding a Doppler insonation angle of >30°. Heart rate, semilunar valve dimension, and VTI determined minute VTI and CO. Inter- and intrarater variability were evaluated in a random 10% subset. RESULTS: Minute VTI and CO measurements were feasible in 67% to 89% of fetuses in this retrospective study. Minute VTI and CO increased with estimated fetal weight nonlinearly (R = 0.61-0.94). The mean inter- and intrarater variability for VTI, 6% and 5.7%, were significantly less than for CO, 25% and 23.7% (P < .001 for all). CONCLUSIONS: Minute VTI is an easily measured, highly reproducible method of quantifying fetal ventricular systolic function. Variability in calculated CO from valve measurement differences is minimized by solely using VTI. Nomograms of minute VTI provide an efficient and precise assessment of fetal systolic function and may be used to track fetuses in disease states with low or high CO.

ABSTRACT

Background Stiffer aortas are associated with a faster rate of aortic root (AoR) dilation and higher risk of aortic dissection in patients with Marfan syndrome. We have previously shown that mild aerobic exercise reduces aortic stiffness and rate of AoR dilation in a Marfan mouse model. In this study, we investigated if these results could be translated to pediatric patients with Marfan syndrome. Methods and Results We enrolled 24 patients with Marfan syndrome aged 8 to 19 years to participate in a 6-month physical activity intervention, excluding those with ventricular dysfunction or prior history of aortic surgery. We instructed patients to take 10 000 steps per day, tracked by an activity tracker. At baseline and 6 months, we measured AoR dimension, arterial stiffness, endothelial function, physical activity indices, inflammatory biomarkers, and coping scores. Controls consisted of 15 age-matched patients with Marfan syndrome. Twenty-four patients with Marfan syndrome (median age, 14.4 years [interquartile range {IQR}, 12.2-16.8], 14 male patients) were enrolled. Baseline assessment demonstrated that the majority of these patients were sedentary and had abnormal arterial health. Twenty-two patients completed the intervention and took an average of 7709±2177 steps per day (median, 7627 [IQR, 6344-9671]). Patients wore their Garmin trackers at a median of 92.8% (IQR, 84%-97%) of their intervention days. AoR Z score in the intervention group had a significantly lower rate of change per year compared with the controls (rate of change, -0.24 versus +0.008; P=0.01). Conclusions In this clinical intervention in pediatric patients with Marfan syndrome, we demonstrated that a simple physical activity intervention was feasible in this population and has the potential to decrease the AoR dilation rate.

ABSTRACT

Introduction: As we learn more about the novel multisystem inflammatory syndrome in children (MIS-C) associated with COVID-19 infection, the protocols for long-term follow-up have evolved and only some of these protocols have been published. Here, we review the current literature on follow-up guidelines in MIS-C patients. Methods: We conducted a PUBMED search of all articles published on "MIS-C" and the term "follow-up" between 2020 and 2022. Inclusion criteria were that (1) the study was an observational study or case series, and (2) the study population included pediatric population who met the diagnostic criteria for MIS-C. Results: There were 206 publications on MIS-C and follow-up in the last 2 years with 11 studies that fit the inclusion criteria. These papers were representing 11 different centers and encompassed a total of 343 participants. Seven of the 11 studies had participants follow-up with their cardiologist within 1 month of discharge. Between 12% and 62% of patients within each study had depressed left ventricular ejection fraction (LVEF) at admission. At the initial follow-up visit, five studies showed a normal LVEF in all patients while the other seven studies showed 2%-13% patients continuing to have depressed LVEF. In eight of the 11 studies, 9%-52% of patients had coronary artery dilation at admission. At their initial follow-up visit, 3%-28% of patients continued to have coronary artery dilation. Conclusion: There is some institutional variation in the outpatient follow-up protocols in patients diagnosed with MIS-C. A standardized follow-up guidelines might be helpful to monitor long-term prognosis of these patients.

ABSTRACT

IMPORTANCE: Single ventricle CHD affects about 5 out of 100,000 newborns, resulting in complex anatomy often requiring multiple, staged palliative surgeries. Paediatricians are an essential part of the team that cares for children with single ventricle CHD. These patients often encounter their paediatrician first when a complication arises, so it is critical to ensure the paediatrician is knowledgeable of these issues to provide optimal care. OBSERVATIONS: We reviewed the subtypes of single ventricle heart disease and the various palliative surgeries these patients undergo. We then searched the literature to detail the general paediatrician's approach to single ventricle patients at different stages of surgical palliation. CONCLUSIONS AND RELEVANCE: Single ventricle patients undergo staged palliation that drastically changes physiology after each intervention. Coordinated care between their paediatrician and cardiologist is requisite to provide excellent care. This review highlights what to expect when these patients are seen by their paediatrician for either well child visits or additional visits for parental or patient concern.

ABSTRACT

IMPORTANCE: Paediatricians play an integral role in the lifelong care of children with CHD, many of whom will undergo cardiac surgery. There is a paucity of literature for the paediatrician regarding the post-operative care of such patients. OBSERVATIONS: The aim of this manuscript is to summarise essential principles and pertinent lesion-specific context for the care of patients who have undergone surgery or intervention resulting in a biventricular circulation. CONCLUSIONS AND RELEVANCE: Familiarity with common issues following cardiac surgery or intervention, as well as key details regarding specific lesions and surgeries, will aid the paediatrician in providing optimal care for these patients.

ABSTRACT

Objective: Aortic root (AoR) size remains an imperfect predictor of rate of aortic dilation in Marfan syndrome (MFS). Indicators of vascular phenotype such as aortic stiffness have been proposed as additional predictors. In this study we assessed the rate of AoR dilation and stiffness in adult patients with MFS. Methods: We performed a retrospective chart review. We included adult patients with MFS (aged 20-40 years) with at least 2 local echocardiograms 6 months apart (no aortic surgery in-between). A blinded observer analyzed the echocardiograms. AoR dilation rate and stiffness were calculated. Results: Thirty-two patients (53% women; median age, 21.1; interquartile range [IQR], 19-24 years at first echocardiogram) were included. AoR dilation rate in the entire cohort was 0 to 8 mm/year (median, 0.465; IQR, 0.23-1.45 mm/year). Multiple linear regression analysis showed that baseline AoR stiffness was associated with AoR dilation rate (ß = 0.0004; P < .001 for elastic modulus), whereas baseline age and baseline AoR dimension were not. Eighteen of these 32 patients (56%) eventually had AoR surgery (Sx) and 14 did not have surgery (NSx). At baseline, Sx and NSx patients were similar in age. AoR dimension was larger (Sx, 4.27 cm; IQR, 4.05-4.49 cm vs NSx, 3.73 cm; IQR, 3.37-4.09 cm; P = .011) and AoR stiffness was higher in Sx patients (beta stiffness index: median, 23.2; IQR, 17.8-28.6 vs median, 15.6; IQR, 11.6-19.7; P = .024). AoR dilation rate was greater in Sx patients, independent of baseline AoR dimension (1.63 ± 0.41 mm/year vs 0.38 ± 0.08 mm/year; P = .01). Conclusions: Our results showed that AoR dilation rate varies among adult patients with MFS and is associated with baseline AoR stiffness, measured by echocardiography. Further studies are warranted to determine how aortic stiffness can be implemented clinically to refine management in patients with MFS.

ABSTRACT

PURPOSE: In a large cohort of 373 pediatric patients with Marfan syndrome (MFS) with a severe cardiovascular phenotype, we explored the proportion of patients with MFS with a pathogenic FBN1 variant and analyzed whether the type/location of FBN1 variants was associated with specific clinical characteristics and response to treatment. Patients were recruited on the basis of the following criteria: aortic root z-score > 3, age 6 months to 25 years, no prior or planned surgery, and aortic root diameter < 5 cm. METHODS: Targeted resequencing and deletion/duplication testing of FBN1 and related genes were performed. RESULTS: We identified (likely) pathogenic FBN1 variants in 91% of patients. Ectopia lentis was more frequent in patients with dominant-negative (DN) variants (61%) than in those with haploinsufficient variants (27%). For DN FBN1 variants, the prevalence of ectopia lentis was highest in the N-terminal region (84%) and lowest in the C-terminal region (17%). The association with a more severe cardiovascular phenotype was not restricted to DN variants in the neonatal FBN1 region (exon 25-33) but was also seen in the variants in exons 26 to 49. No difference in the therapeutic response was detected between genotypes. CONCLUSION: Important novel genotype-phenotype associations involving both cardiovascular and extra-cardiovascular manifestations were identified, and existing ones were confirmed. These findings have implications for prognostic counseling of families with MFS.

ABSTRACT

Background: The impact of adjunctive anti-inflammatory treatment on outcomes for patients with Kawasaki disease (KD) and coronary artery aneurysms (CAAs) is unknown. Methods: Using data from the International KD Registry in patients with ≥ medium CAA we evaluate associations of treatment with outcomes and major adverse cardiac events (MACE). Results: Medium or large CAA was present in 527 (32%) patients. All were treated with intravenous immunoglobulin (IVIG), 70% were male, and the median age was 1.3 years (interquartile range: 0.4-4.0 years). The most common acute therapies included single IVIG alone in 243 (46%), multiple IVIG in 100 (19%), multiple IVIG + corticosteroids in 75 (14%), and multiple IVIG + infliximab + corticosteroids in 44 (8%) patients. Patients who received therapy beyond single IVIG had a larger CA z-score at baseline (P < 0.001) and a higher rate of bilateral CAA (P < 0.001). Compared with IVIG alone, early adjunctive treatments (within 3 days of initial IVIG) were not associated with time to CAA regression or MACE, whereas later adjunctive therapy was associated with MACE and longer time to CAA regression. Patients receiving IVIG plus steroids vs IVIG alone had a trend towards shorter time to CAA regression and lower risk of MACE (P = 0.07). A larger CAA z-score at baseline was the strongest predictor of an increase in the CAA z-score over follow-up, lower likelihood of CAA regression, and higher risk of MACE. Conclusions: Persistence of CAA and MACE are more strongly associated with baseline severity CAA than with acute adjuvant anti-inflammatory therapy. Patients who received late adjunctive therapy are at higher risk for worse outcomes.


Contexte: L'incidence d'un traitement anti-inflammatoire d'appoint chez les patients atteints de la maladie de Kawasaki (MK) compliquée d'anévrismes coronariens est inconnue. Méthodologie: À partir de données provenant du registre international de la maladie de Kawasaki portant sur les patients ayant subi des anévrismes coronariens modérés ou importants, nous avons évalué l'incidence des différents traitements sur les résultats cliniques et les événements cardiovasculaires indésirables majeurs (ECIM). Résultats: Des anévrismes coronariens modérés ou importants ont été relevés chez 527 patients (32 %). Tous les patients recevaient des immunoglobulines administrées par voie intraveineuse (IgIV); 70 % d'entre eux étaient de sexe masculin, et leur âge médian était de 1,3 an (écart interquartile : de 0,4 an à 4,0 ans). Les traitements d'urgence les plus fréquents comprenaient un seul traitement par IgIV chez 243 patients (46 %), plusieurs traitements par IgIV chez 100 patients (19 %), une association de plusieurs traitements IgIV et de corticostéroïdes chez 75 patients (14 %) et une association de plusieurs traitements IgIV, de corticostéroïdes et d'infliximab chez 44 patients (8 %). Les patients ayant reçu un traitement autre qu'un seul traitement IgIV présentaient des scores z initiaux plus élevés pour le diamètre des artères coronaires (P < 0,001) et un taux plus élevé d'anévrismes coronariens bilatéraux (P < 0,001). En comparaison d'un traitement par IgIV seulement, les traitements d'appoint précoces (administrés dans les trois jours suivant le début du traitement par IgIV) n'ont pas eu d'incidence sur la durée avant la régression des anévrismes coronariens ni sur la survenue d'ECIM, alors que les traitements d'appoint plus tardifs ont été associés à un risque plus élevé d'ECIM et à une régression plus tardive des anévrismes coronariens. Les patients ayant reçu une association d'IgIV et de corticostéroïdes avaient tendance à présenter une régression plus rapide des anévrismes coronariens et un plus faible risque d'ECIM que ceux recevant uniquement un traitement par IgIV (P = 0,07). Un score z initial plus élevé pour un anévrisme coronarien était le facteur prédictif le plus puissant d'une augmentation du score z pendant la période de suivi, d'une probabilité plus faible de régression de l'anévrisme et d'un risque plus élevé d'ECIM. Conclusions: La gravité initiale de l'anévrisme coronarien est plus fortement associée à la persistance de l'anévrisme et à la survenue d'ECIM que le recours à un traitement anti-inflammatoire d'urgence en appoint. Les patients recevant un traitement d'appoint tardif étaient par ailleurs plus susceptibles de présenter des résultats défavorables.

ABSTRACT

Background: Exercise training programs can effectively enhance exercise capacity in adults with congenital heart disease, including Fontan patients. However, few studies have explored the impact of exercise training exclusively on paediatric Fontan cohorts. This study systematically reviews exercise capacity in paediatric Fontan patients and the impact of training programs on their cardiovascular health. Methods: Medline and Embase were searched for articles published between January 1990 and November 2021. Studies were included in which data could be analyzed discretely for patients who had undergone the Fontan procedure and were ≤20 years old at the time of study. Cardiopulmonary exercise parameters were extracted from all studies, and training protocols were collected from training programs. Results: The studies demonstrated that Fontan patients exhibit significantly diminished peak exercise capacity relative to healthy peers. We identified 9 training programs that exclusively studied Fontan patients ≤20 years. The programs ranged from 6 weeks to 12 months in duration, with 8 programs incorporating aerobic activity and 1 focused only on inspiratory muscle training. At least 1 measure of maximal or submaximal exercise capacity improved significantly within each program in which statistical analysis was performed, with no reported adverse events. There were 2 additional training programs in which the patients were predominantly (>65%), but not exclusively, Fontan patients. Conclusions: Overall, the results indicate that exercise training programs can safely and effectively improve at least 1 measure of exercise capacity in paediatric Fontan patients.


Contexte: Les programmes d'entraînement peuvent améliorer efficacement la tolérance à l'effort des adultes atteints de cardiopathies congénitales, y compris les patients ayant subi l'intervention de Fontan. Toutefois, peu d'études portant sur l'effet de l'entraînement à l'effort ont été menées exclusivement au sein de cohortes d'enfants ayant subi l'intervention de Fontan. Notre revue systématique porte sur la tolérance à l'effort d'enfants ayant subi l'intervention de Fontan, de même que sur l'effet des programmes d'entraînement sur leur santé cardiovasculaire. Méthodologie: Nous avons effectué des recherches dans MEDLINE et Embase afin de recenser les articles publiés entre janvier 1990 et novembre 2021. Les études retenues comprenaient des données qui pouvaient être l'objet d'une analyse discrète et qui se rapportaient à des patients ayant subi l'intervention de Fontan et étant âgés de 20 ans ou moins lors de leur participation aux études. Nous avons consigné les paramètres d'entraînement cardiopulmonaire de toutes les études, de même que les protocoles des programmes d'entraînement. Résultats: Les études ont démontré que les patients qui ont subi l'intervention de Fontan présentent une tolérance à l'effort maximal significativement réduite par rapport aux pairs en bonne santé. Nous avons dénombré neuf programmes d'entraînement ayant servi exclusivement à des études portant sur des patients âgés de 20 ans ou moins qui avaient subi l'intervention de Fontan. La durée des programmes allait de six semaines à 12 mois. Huit programmes intégraient des activités aérobiques et un était axé uniquement sur l'entraînement musculaire inspiratoire. Les résultats pour au moins un indicateur de la tolérance à l'effort maximal ou sous-maximal se sont améliorés de façon significative dans chaque programme comportant une analyse statistique, sans qu'aucun événement indésirable soit signalé. Nous avons recensé deux autres programmes d'entraînement dont les participants étaient principalement (plus de 65 %), mais pas exclusivement, des patients ayant subi l'intervention de Fontan. Conclusions: Dans l'ensemble, les résultats indiquent que les programmes d'entraînement à l'effort peuvent améliorer efficacement et en toute sécurité au moins un indicateur de la tolérance à l'effort chez les enfants ayant subi l'intervention de Fontan.

ABSTRACT

OBJECTIVE: To evaluate practice variation in pharmacologic management in the International Kawasaki Disease Registry (IKDR). STUDY DESIGN: Practice variation in intravenous immunoglobulin (IVIG) therapy, anti-inflammatory agents, statins, beta-blockers, antiplatelet therapy, and anticoagulation was described. RESULTS: We included 1627 patients from 30 IKDR centers with maximum coronary artery aneurysm (CAA) z scores 2.5-4.99 in 848, 5.0-9.99 in 349, and ≥10.0 (large/giant) in 430 patients. All centers reported IVIG and acetylsalicylic acid (ASA) as primary therapy and use of additional IVIG or steroids as needed. In 23 out of 30 centers, (77%) infliximab was also used; 11 of these 23 centers reported using it in <10% of their patients, and 3 centers used it in >20% of patients. Nonsteroidal anti-inflammatory agents were used in >10% of patients in only nine centers. Beta-blocker (8.8%, all patients) and abciximab (3.6%, all patients) were mainly prescribed in patients with large/giant CAAs. Statins (2.7%, all patients) were mostly used in one center and only in patients with large/giant CAAs. ASA was the primary antiplatelet modality for 99% of patients, used in all centers. Clopidogrel (18%, all patients) was used in 24 centers, 11 of which used it in >50% of their patients with large/giant CAAs. CONCLUSIONS: In the IKDR, IVIG and ASA therapy as primary therapy is universal with common use of a second dose of IVIG for persistent fever. There is practice variation among centers for adjunctive therapies and anticoagulation strategies, likely reflecting ongoing knowledge gaps. Randomized controlled trials nested in a high-quality collaborative registry may be an efficient strategy to reduce practice variation.

ABSTRACT

OBJECTIVE: To test feasibility of tele-clinic visits using parentally acquired vital signs and focused echocardiographic images in patients with Marfan syndrome. STUDY DESIGN: We included patients with Marfan syndrome aged 5-19 years followed in our clinic. We excluded patients with Marfan syndrome and history of previous aortic root (AoR) surgery, cardiomyopathy, arrhythmia, or AoR ≥4.5 cm. We trained parents in-person to acquire focused echocardiographic images on their children using a hand-held device as well as how to use a stadiometer, scale, blood pressure (BP) machine, and a digital stethoscope. Before tele-clinic visits, parents obtained the echocardiographic images and vital signs. We compared tele-clinic and on-site clinic visit data. Parental and clinic echocardiograms were independently analyzed. RESULTS: Fifteen patient/parent pairs completed tele-clinic visits, conducted at a median of 7.0 (IQR 3.0-9.9) months from the in-person training session. Parents took a median of 70 (IQR 60-150) minutes to obtain the height, weight, heart rate, BP, cardiac sounds, and echocardiographic images before tele-clinic visits. Systolic BP was greater on-site than at home (median +13 mm Hg, P = .014). Height, weight, diastolic BP, heart rate, and AoR measurements were similar. CONCLUSIONS: This study provides information for implementing tele-clinic visits using parentally acquired vital signs and echocardiographic images in patients with Marfan syndrome. The results show that tele-clinic visits are feasible and that parents were able to obtain focused echocardiographic images on their children. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03581682.

ABSTRACT

Background In a recent multicenter study of perinatal outcome in fetuses with Ebstein anomaly or tricuspid valve dysplasia, we found that one third of live-born patients died before hospital discharge. We sought to further describe postnatal management strategies and to define risk factors for neonatal mortality and circulatory outcome at discharge. Methods and Results This 23-center, retrospective study from 2005 to 2011 included 243 fetuses with Ebstein anomaly or tricuspid valve dysplasia. Among live-born patients, clinical and echocardiographic factors were evaluated for association with neonatal mortality and palliated versus biventricular circulation at discharge. Of 176 live-born patients, 7 received comfort care, 11 died <24 hours after birth, and 4 had insufficient data. Among 154 remaining patients, 38 (25%) did not survive to discharge. Nearly half (46%) underwent intervention. Mortality differed by procedure; no deaths occurred in patients who underwent right ventricular exclusion. At discharge, 56% of the cohort had a biventricular circulation (13% following intervention) and 19% were palliated. Lower tricuspid regurgitation jet velocity (odds ratio [OR], 2.3 [1.1-5.0], 95% CI, per m/s; P=0.025) and lack of antegrade flow across the pulmonary valve (OR, 4.5 [1.3-14.2]; P=0.015) were associated with neonatal mortality by multivariable logistic regression. These variables, along with smaller pulmonary valve dimension, were also associated with a palliated outcome. Conclusions Among neonates with Ebstein anomaly or tricuspid valve dysplasia diagnosed in utero, a variety of management strategies were used across centers, with poor outcomes overall. High-risk patients with low tricuspid regurgitation jet velocity and no antegrade pulmonary blood flow should be considered for right ventricular exclusion to optimize their chance of survival.

ABSTRACT

PURPOSE OF REVIEW: Children and adolescents with congenital heart disease (CHD) often have decreased exercise capacity and muscle mass. Exercise has numerous health benefits and can improve exercise capacity and muscle mass. As such, guidelines recommend 60 min of daily physical activity in the majority of pediatric CHD patients. Despite these known benefits and guidelines, children and adolescents with CHD often do not exercise regularly. The purpose of this review is to summarize the current literature on exercise in this population. RECENT FINDINGS: With recent advancements in the field, clinical focus in pediatric cardiology has expanded from improving mortality to improving long-term outcomes and quality of life. As part of this paradigm shift, there is ongoing research on safety, impact, and effective delivery of exercise to this population with the overarching goal of promoting an active lifestyle. SUMMARY: Exercise interventions are generally safe, feasible, and beneficial in children and adolescents with CHD. There is growing evidence demonstrating the benefits and utility of exercise as a prescription rather than restriction in pediatric CHD patients. Novel approaches are needed for effective delivery of exercise in this population. Further studies are warranted for assessment of long-term benefits of exercise in pediatric CHD patients.

ABSTRACT

Telehealth is a promising new tool in medicine that has changed the landscape of medical care. The benefits of telehealth technology are immense, including improved access to care and potential savings in monetary and opportunity costs. Current challenges of incorporating telehealth services into regular clinical care include licensure and regulatory barriers, difficulty obtaining insurance reimbursements, and high costs of setting up successful telehealth infrastructures. These challenges threaten telehealth's future scalability and expansion to reach all patients in need.

ABSTRACT

Background Pediatric heart transplant recipients have high-risk cardiovascular profiles that can affect their long-term outcomes; however, promoting exercise and healthy diet has not been a major focus in the field. The objective of this study was to test the feasibility and impact of a supervised exercise and diet intervention delivered via live videoconferencing in this population. Methods and Results Patients 8 to 19 years of age at least 1 year post heart transplantation were enrolled. The 12- to 16-week intervention phase included live video-supervised exercise (×3/week) and nutrition (×1/week) sessions. The 12- to 16-week maintenance phase included ×1/week live video-supervised exercise and nutrition sessions and ×2/week self-directed exercise sessions. Cardiac, vascular, nutritional, and functional health indices were obtained at baseline, after intervention, and after maintenance. Fourteen patients (median age, 15.2; interquartile range, 14.3-16.7 years) at a median of 3.3 (interquartile range, 1.5-9.7) years after heart transplant completed the intervention. Patients attended 89.6±11% of exercise and 88.4±10% of nutrition sessions during the intervention and 93.4±11% of exercise and 92.3±11% of nutrition sessions during maintenance. After intervention, body mass index percentile (median, -27%; P=0.02), endothelial function (median, +0.29; P=0.04), maximum oxygen consumption (median, +2 mL/kg per minute; P=0.002). Functional Movement Screening total score (median, +2.5; P=0.002) and daily consumption of saturated fat (median, -6 g; P=0.02) improved significantly. After maintenance, improvements in maximum oxygen consumption (median, +3.2 mL/kg per minute; P=0.02) and Functional Movement Screening total score (median, +5; P=0.002) were sustained. Conclusions In pediatric heart transplant recipients, a live video-supervised exercise and diet intervention is feasible. Our results demonstrate excellent adherence with significant improvements in cardiovascular and functional health. Clinical Trial Registration URL: http://www.clinicaltrials.gov.
