This cohort study aims to explore weight gain and stunting in the Syracuse, NY paediatric refugee population.

Demographics, height and weight were collected through chart review and electronic abstraction in 2019–2020 for N 941. BMI was calculated using Centers for Disease Control and Prevention software and metrics; obesity was defined as a BMI ≥ 95th percentile while overweight was a BMI percentile ≥85th but <95th percentile. Stunting was based on the WHO’s definition of a height-for-age Z score <−2·0. Differences in BMI percentiles were assessed using chi-square tests, t-tests or one-way ANOVA while BMI change over time was analysed using linear mixed modelling.

Paediatric refugees.

The cohort was 49 % female with a mean age (sd) upon arrival of 8·9 (4·7) years. Sixty-one percent of refugees were from Africa, with 33 % from the Middle East. Stunting was observed in 9·7 % of participants upon arrival and varied significantly by region of origin. Obesity was observed in 24 % of refugees after living in the US for 5 or more years while the frequency of overweight at 5 plus years was 19·4 %. In linear mixed modelling, stunting, region of origin and duration of residence in the US were found to be significant predictors of BMI change over time.

Results support implementing targeted obesity prevention interventions in the Pediatric International Health Clinic refugee population and highlight additional risk for those arriving with stunting.

Kawasaki disease is an acute childhood vasculitis that may cause coronary artery aneurysms, raising concern for long-term myocardial dysfunction. Exercise stress echocardiography provides a noninvasive assessment of systolic and diastolic reserve, yet data comparing exercise responses in Kawasaki disease patients with contemporary coronary risk stratification are limited.

We retrospectively analysed exercise stress echocardiograms in patients with a history of Kawasaki disease-related coronary artery aneurysm (maximum coronary artery z-score ≥2.5) and age-matched controls without cardiac disease. Two-dimensional echocardiography was performed at rest and during early recovery following a standardised ergometer exercise test. Left ventricular and left atrial strain and mitral inflow velocities were measured. Within-group pre- and post-exercise changes were assessed using paired t-tests. Linear mixed-effects models evaluated differences in the magnitude of exercise-induced change between groups.

There were 34 and 27 patients in the Kawasaki disease and control cohorts, respectively. The Kawasaki disease cohort had a mean maximal coronary z-score of 3.8 ± 2.1. Both groups demonstrated significant pre- to post-exercise changes in left ventricular longitudinal strain and mitral A velocity. Additional systolic and diastolic parameter changes were observed within the Kawasaki disease cohort. Mixed-effects modelling revealed no significant differences in the magnitude of exercise-induced change between Kawasaki disease patients and controls.

In paediatric patients with a remote history of Kawasaki disease and mild to moderate coronary artery aneurysms, exercise stress echocardiography demonstrated no differences in the magnitude of exercise-induced changes in systolic and diastolic indices compared to controls.

Delirium is an inherently prevalent and particularly challenging aspect of pediatric heart disease that benefits from engagement of a vulnerable parent population. However, parental experience of witnessing their child’s episode(s) of delirium is seldom reported on in the cardiac population. Our aim was to identify and describe the specific impact of bearing witness to delirium symptoms as a parent or caregiver.

A cross-sectional online survey was distributed via parent social media groups and e-mail lists, displayed at conferences, and posted in clinical spaces from August 2023 through March 2024.

Fifty-one parents/caregivers provided meaningful responses. Most parents/caregivers were white (47, 92%), married (43/50, 86%), female (43, 84%), had a bachelor’s degree or greater (39, 77%), and nearly half (24, 47%) had a household income greater than $150,000. Half (26, 51%) of the children with delirum symptoms were less than 3 years old at first episode. Most (40, 78%) parents/caregivers described witnessing their child’s delirium symptoms as “very” or “extremely distressing” and 17 (33%) were “very” or “extremely fearful” of further episodes. Only 39% (19/51) of parents/caregivers received support despite 90% indicating they would have wanted more support. Of the 13 parents/caregivers who indicated their experience with delirium still impacts their daily life, seven screened positive by Impact of Event Scale 6 criteria for probable post-traumatic stress disorder.

This survey provides new evidence on the distressing nature of witnessing a child’s delirium episodes(s). Recognition of the impact on parents/caregivers and efforts to improve support and parental education should be undertaken.

Dilated cardiomyopathy is a rare but severe myocardial disease in the paediatric population, often leading to heart failure, heart transplantation, or sudden cardiac death. Genetic factors are a major contributor to childhood dilated cardiomyopathy. Recently, biallelic variants in the PPP1R13L gene have been implicated in a novel syndromic form of early-onset dilated cardiomyopathy, characterised by cardiac dysfunction alongside variable ectodermal features.

We report a 4-year-old boy who presented with decompensated heart failure and echocardiographic findings consistent with dilated cardiomyopathy. Syndromic features included sparse, dry hair, high anterior hairline, broad nasal bridge, and pointed teeth. Genetic analysis revealed a novel homozygous frameshift variant in the PPP1R13L gene (c.2368_2375dup; p. Pro793Glyfs*32), classified as pathogenic. The clinical course was complicated by recurrent ventricular arrhythmias and ultimately sudden cardiac death.

PPP1R13L-related cardiomyopathy should be considered in children with early-onset dilated cardiomyopathy and syndromic features. Early diagnosis is critical for clinical management, arrhythmia surveillance, and appropriate family counselling.

Renal replacement therapy is sometimes utilised after paediatric heart transplant, although current data on this are extremely limited. We sought to identify incidence of renal replacement therapy and patient characteristics, comorbidities, and outcomes when renal replacement therapy was needed around paediatric heart transplant.

The Pediatric Health Information System database was queried for paediatric intensive care patients who underwent a heart transplant from 2018 to 2021. Demographic and clinical data were analysed. Only patients admitted for heart transplant with heart transplant occurring on day 0 of admission were included to ensure that renal replacement therapy was postoperative.

A total of 235 patients who underwent heart transplant were included. Of these, 22 (9.3%) required renal replacement therapy. Mortality during admission was 3.8% in those without renal replacement therapy and 40.9% of patients requiring renal replacement therapy. Renal replacement therapy was associated with cardiomyopathy, infection, rejection, acute kidney injury, acute hepatic failure, and fluid overload.

Renal replacement therapy was utilised in 9.3% of paediatric heart transplant admissions and is associated with increased mortality. Postoperative need for renal replacement therapy is associated with increased mortality and adverse transplant outcomes.

The bidirectional Glenn surgery is an important staging procedure for patients with single ventricle physiology. Approximately 1000 children are born each year in the United States with this subset of CHD. There is limited data regarding optimal post-operative management for these children. We surveyed paediatric cardiac intensive care providers surrounding their management strategies after the bidirectional Glenn surgery.

An anonymous survey was distributed via email to paediatric cardiac intensive care providers. The survey included anonymised demographic data and focused on post-operative physiologic targets for patients recovering after the bidirectional Glenn surgery.

Thirty-five paediatric cardiac intensive care providers responded to an anonymous 12-question survey. Subjects were mostly comprised of paediatric cardiac intensive care attendings (80%), with an average of 7.86 years of training. The respondents primarily practised in settings with medical trainees, and all practised in settings with extracorporeal membrane oxygenation capabilities.

Respondents were asked to complete a web-based survey. Five of the survey questions were devoted to background demographic data, and seven questions were aimed at identifying physiologic targets. Two of the seven questions were in relation to a provided clinical vignette.

This survey demonstrated that there is a lack of consensus in the management of patients after the bidirectional Glenn surgery. Specifically, granular SpO2, mean arterial pressure, and pH Goals were all less than 75% consensus. This survey highlights the variable practice patterns in providers taking care of patients after the bidirectional Glenn surgery, and further demonstrates the need for physiologic and outcome-driven targets to optimise the post-operative care.

This study aimed to evaluate the characteristics, difficulties, and outcomes of patients who underwent transcatheter ablation treatment due to arrhythmia with a diagnosis of CHD.

A total of 166 patients (189 substrates) with CHD who underwent catheter ablation between November 2013 and 2023 were evaluated retrospectively. EnSite™ (St Jude Medical Inc., St Paul, MN, USA) was used in all patients.

The mean age was 14.8 ± 7.9 years (2.9–43 years). The most common CHD’s were Ebstein anomaly (n: 40), tetralogy of Fallot (n: 31), atrial septal defect (n: 25), ventricular septal defect (n: 22), great artery transposition (D/L TGA, n: 12), and complex CHD in single ventricle physiology (n: 9). The most common arrhythmia mechanisms were Wolf-Parkinson-White syndrome (WPW, n: 50), intraatrial reentrant tachycardia (IART, n: 39), typical atrioventricular nodal reentrant tachycardia (AVNRT, n: 37), and ventricular tachycardia-ventricular extrasystoles (VT/VES, n: 23). There was more than one arrhythmia in 23 patients and multiple manifest accessory pathways in 10 patients. The average procedure time was 174 ± 69.3 minutes, and the average fluoro time was 8.3 minutes. While successful ablation was performed in 176/189 (acute success 93.1%) substrates, the procedure was unsuccessful in five patients and suboptimal in eight patients. Recurrence was observed in 11 patients (6.4%) during a mean follow-up period of 49.2 ± 30.1 months. A second ablation was performed on 13 patients. Acute success was achieved in all except one patient. A total of 11 patients are being followed up with medical treatment.

Despite the complex anatomy, age, operations, and limited vascular access possibilities in patients diagnosed with CHD, transcatheter ablation treatment with advances in electrophysiology, the introduction of different energy types, special ablation catheters, multipolar mapping catheters, and 3D nonfluoroscopic mapping systems seems to be a safe and effective option.

With more than 1 million children in the United States living with a heart defect or condition, it is important to identify interventions that may minimise the long-term impacts of repeated medical surveillance and care. Thus, the purpose of this quasi-experimental study was to examine relationships between facility dog intervention and young children’s anxiety during outpatient echocardiogram.

Participants were seventy children aged 18 months to 8 years undergoing echocardiogram in a paediatric cardiology clinic. Child anxiety was scored by a trained nurse observer pre- and post-procedure using the modified Yale Preoperative Anxiety Scale. Facility dog intervention included individualised play, positioning, therapeutic conversation and touch, and emotional support throughout to promote coping and compliance. Parents and staff completed a post-procedural perceptions survey about their experiences.

Paired samples t-tests demonstrated child anxiety levels were significantly lower post-procedure compared to pre-procedure (Z = −3.974, p < .001). This direction held for nearly all participants; however, those with prior echocardiogram history demonstrated significantly higher anxiety levels at the pre-procedural timepoint (z = −2.442, p = .015). Caregivers (97.2%) and staff (87.9%) agreed or strongly agreed that facility dog intervention was helpful in this context.

Facility dog intervention was associated with a significant reduction in young children’s anxiety across procedural timepoints in outpatient echocardiography. The intervention was perceived as helpful by families and staff; no workflow changes or barriers were noted. Thus, facility dog intervention may be a well-received and promising care innovation for this vulnerable chronic population.

Amiodarone is a frequently used medication in paediatric patients to manage atrial and ventricular arrhythmias, but its acute haemodynamic effects, particularly in children, remain underexplored. This retrospective, single-centre study aimed to characterise the clinical impact of amiodarone intravenous infusions on heart rate, blood pressure, oxygen delivery, and transaminase levels within the first 48 hours of amiodarone initiation in paediatric cardiac ICU patients.

Single-centre, retrospective study of patients receiving amiodarone infusions, with measurements taken at baseline and at various intervals up to 48 hours after initiation. The primary outcome was the effect on heart rate, while secondary outcomes included blood pressure, arterial saturation, near-infrared spectroscopy values, central venous pressure, and transaminase levels. Several types of analysis models were employed to assess the results.

Data were collected from 87 paediatric patients. No significant changes in liver enzymes, blood pressure, or renal oxygen extraction were observed. These findings provide novel insights into the acute haemodynamic effects of amiodarone infusions in paediatric patients, suggesting that while amiodarone significantly lowers heart rate, it does not substantially affect oxygen delivery or necessitate increased vasoactive support.

Amiodarone infusions are associated with a significant decrease in heart rate without greatly impacting oxygen delivery or requiring increased vasoactive support. Heart rate decreases most until a cumulative dose of 30,000 mcg/kg, and heart rate decrease is most pronounced in those with ventricular tachycardia.
