To define the incidence of definitive necrotising enterocolitis in term infants with CHD and identify risk factors for morbidity/mortality.

We performed a 20-year (2000–2020) single-institution retrospective cohort study of term infants with CHD admitted to the Boston Children’s Hospital cardiac ICU with necrotising enterocolitis (Bell’s stage ≥ II). The primary outcome was a composite of in-hospital mortality and post-necrotising enterocolitis morbidity (need for extracorporeal membrane oxygenation, multisystem organ failure based on the paediatric sequential organ failure assessment score, and/or need for acute gastrointestinal intervention). Predictors included patient characteristics, cardiac diagnosis/interventions, feeding regimen, and severity measures.

Of 3933 term infants with CHD, 2.1% (n = 82) developed necrotising enterocolitis, with 67% diagnosed post-cardiac intervention. Thirty (37%) met criteria for the primary outcome. In-hospital mortality occurred in 14 infants (17%), of which nine (11%) deaths were attributable to necrotising enterocolitis. Independent predictors of the primary outcome included moderate to severe systolic ventricular dysfunction (odds ratio 13.4,confidence intervals 1.13–159) and central line infections pre-necrotising enterocolitis diagnosis (odds ratio 17.7, confidence intervals 3.21–97.0) and mechanical ventilation post-necrotising enterocolitis diagnosis (odds ratio 13.5, confidence intervals 3.34–54.4). Single ventricle, ductal dependency, and feeding related factors were not independently associated with the primary outcome.

The incidence of necrotising enterocolitis was 2.1% in term infants with CHD. Adverse outcomes occurred in greater than 30% of patients. Presence of systolic dysfunction and central line infections prior to diagnosis and need for mechanical ventilation after diagnosis of necrotising enterocolitis can inform risk triage and prognostic counseling for families.

CHD are among the most common congenital defects. Due to the chronic nature of CHD, patients face various risk factors that threaten their mental health. However, a comprehensive understanding of the medical and social predictors of mental health issues in adults with CHD is lacking. This study aims to investigate the prevalence of anxiety and depression in adults with CHD.

This cross-sectional descriptive study focused on adults with CHD in Kerman, Iran. The participants completed demographic information alongside two psychological assessment tools: the Beck Anxiety Inventory (BAI) and the Depression Anxiety Stress Scales (DASS)-21. The data were analyzed using SPSS 26.

The mean age of the participants was 29.94 ± 12.36 years, and 63.8% were female. According to the DASS, 73.4% did not have depression, 61% did not have anxiety, and 76.2% did not have stress. In total, 19% had mild stress, and 4.8% had moderate stress. According to the BAI, 27.6% did not have anxiety. Individual characteristics were not significantly associated with depression. However, gender, age, and type of surgery were significantly associated with anxiety. Cyanosis was significantly associated with stress.

The results show that mental disorders like depression, anxiety, and stress are highly prevalent in adults with CHD. The prevalence depends on individual factors such as age, gender, and disease severity. Therefore, it is recommended that mental disorders in this population be evaluated and treated accurately.

This study investigated the association between early extubation (EE) and the degree of postoperative intensive care unit (ICU) support after the Fontan procedure, specifically evaluating the volume of postoperative intravenous fluid (IVF) and vasoactive-inotropic score (VIS).

Retrospective analysis of patients who underwent Fontan palliation from 2008 to 2018 at a single center was completed. Patients were initially divided into pre-institutional initiative towards EE (control) and post-initiative (modern) cohorts. Differences between the cohorts were assessed using t-test, Wilcoxon, or chi-Square. Following stratification by early or late extubation, four groups were compared via ANOVA or Kruskal-Wallis Test.

There was a significant difference in the rate of EE between the control and modern cohorts (mean 42.6 versus 75.7%, p = 0.01). The modern cohort demonstrated lower median VIS (5 versus 8, p = 0.002), but higher total mean IVF (101±42 versus 82 ±27 cc/kg, p < 0.001) versus control cohort. Late extubated (LE) patients in the modern cohort had the highest VIS and IVF requirements. This group received 67% more IVF (140 ± 53 versus 84 ± 26 cc/kg, p < 0.001) and had a higher median VIS at 24 hours (10 (IQR, 5–10) versus 4 (IQR, 2–7), p < 0.001) versus all other groups. In comparison, all EE patients had a 5-point lower median VIS when compared to LE patients (3 versus 8, p= 0.001).

EE following the Fontan procedure is associated with reduced post-operative VIS. LE patients in the modern cohort received more IVF, potentially identifying a high-risk subgroup of Fontan patients deserving of further investigation.

There are little reported data on the perspectives of fathers caring for children with chronic conditions. Although survival of children with advanced heart disease has improved, long-term morbidity remains high. This study describes the experience and prognostic awareness of fathers of hospitalised children with advanced heart disease.

Cross-sectional survey study of parents caring for children hospitalised with advanced heart disease admitted for ≥ 7 days over a one-year period. One parent per patient completed surveys, resulting in 27 father surveys. Data were analysed using descriptive methods.

Nearly all (96%) of the fathers reported understanding their child’s prognosis “extremely well” or “well,” and 59% felt they were “very prepared” for their child’s medical problems. However, 58% of fathers wanted to know more about prognosis, and 22% thought their child’s team knew something about prognosis that they did not. Forty-one per cent of fathers did not think that their child would have lifelong limitations, and 32% anticipated normal life expectancies. All 13 fathers who had a clinical discussion of what would happen if their child got sicker found this conversation helpful. Nearly half (43%) of the fathers receiving new prognostic information or changes to treatment course found it “somewhat” or “a little” confusing.

Fathers report excellent understanding of their child’s illness and a positive experience around expressing their hopes and fears. Despite this, there remain many opportunities to improve communication, prognostic awareness, and participation in informed decision-making of fathers of children hospitalised with advanced heart disease.

Low pre-albumin, body mass index, and thiamine levels have been associated with poor nutritional status and cognitive/memory deficits in adult heart failure patients. However, the relationship of these nutritional/dietary intake biomarkers to cognition has not been assessed in adolescents post-Fontan procedure and healthy controls.

This is a cross-sectional study. Adolescents (14–21 years of age) post-Fontan completion were recruited from paediatric cardiology clinics and controls from the community. The Montreal Cognitive Assessment was administered (normal ≥ 26), and blood draw (thiamine [normal 70–110 nmol/L] and pre-albumin levels [adolescent normal 23–45 mg/dL]) and the Thiamine Food Frequency Questionnaire were completed by all participants.

Seventy subjects, 40 post-Fontan (mean age 16 ± 1.6, female 51%, Hispanic 44%, hypoplastic left heart syndrome 26%) and 30 controls (mean age 16.8 ± 1.9, female 52%, Hispanic 66%), were participated. Post-Fontan group had lower median total cognitive scores (23 versus 29, p < 0.001), pre-albumin levels (23 versus 27, p = 0.013), and body mass index (20 versus 24, p = 0.027) than controls. Post-Fontan group had higher thiamine levels than controls (127 versus 103, p = 0.033). Lower pre-albumin levels (< 23) and underweight body mass index were associated with abnormal total cognitive scores (p = 0.030). Low pre-albumin level (p = .038) was an independent predictor of worse cognition.

Lower pre-albumin was an independent predictor for worse cognition in adolescents post-Fontan. Lower pre-albumin levels may reflect chronic liver changes or protein-losing enteropathy seen in Fontan physiology. These findings highlight the possibility for nutrition-induced cognitive changes.

There is variation in care and hospital length of stay following surgical repair of ventricular septal defects. The use of clinical pathways in a variety of paediatric care settings has been shown to reduce practice variability and overall length of stay without increasing the rate of adverse events.

A clinical pathway was created and used to guide care following surgical repair of ventricular septal defects. A retrospective review was done to compare patients two years prior and three years after the pathway was implemented.

There were 23 pre-pathway patients and 25 pathway patients. Demographic characteristics were similar between groups. Univariate analysis demonstrated a significantly shorter time to initiation of enteral intake in the pathway patients (median time to first enteral intake after cardiac ICU admission was 360 minutes in pre-pathway patients and 180 minutes in pathway patients, p < 0.01). Multivariate regression analyses demonstrated that the pathway use was independently associated with a decrease in time to first enteral intake (–203 minutes), hospital length of stay (–23.1 hours), and cardiac ICU length of stay (–20.5 hours). No adverse events were associated with the use of the pathway, including mortality, reintubation rate, acute kidney injury, increased bleeding from chest tube, or readmissions.

The use of the clinical pathway improved time to initiation of enteral intake and decreased length of hospital stay. Surgery-specific pathways may decrease variability in care while also improving quality metrics.

Chylothorax following paediatric cardiac surgery is associated with significant morbidity, particularly those that are refractory to conservative therapy. It is our impression that there is important variability in the medical, surgical, and interventional therapies used to manage refractory chylothorax between congenital heart programmes. We therefore conducted a survey study of current practices for managing refractory chylothorax.

The Chylothorax Work Group, formed with the support of the Pediatric Cardiac Critical Care Consortium, designed this multi-centre survey study with a focus on the timing and indication for utilising known therapies for refractory chylothorax. The survey was sent to one chylothorax expert from each Work Group centre, and results were summarised and reported as the frequency of given responses.

Of the 20 centres invited to participate, 17 (85%) submitted complete responses. Octreotide (13/17, 76%) and sildenafil (8/17, 47%) were the most utilised medications. Presently, 9 (53%) centres perform pleurodesis, 15 (88%) perform surgical thoracic duct ligation, 8 (47%) perform percutaneous lymphatic interventions, 6 (35%) utilise thoracic duct decompression procedures, and 3 (18%) perform pleuroperitoneal shunts. Diagnostic lymphatic imaging is performed prior to surgical thoracic duct ligation in only 7 of the 15 (47%) centres that perform the procedure. Respondents identified barriers to referring and transporting patients to centres with expertise in lymphatic interventions.

There is variability in the treatment of refractory post-operative chylothorax across a large group of academic heart centres. Few surveyed heart centres have replaced surgical thoracic duct ligation or pleurodesis with image-guided selective lymphatic interventions.

Kawasaki disease is a systemic vascular disease with an unclear pathophysiology that primarily affects children under the age of five. Research on immune control in Kawasaki disease has been gaining attention. This study aims to apply a bibliometric analysis to examine the present and future directions of immune control in Kawasaki disease.

By utilizing the themes “Kawasaki disease,” “Kawasaki syndrome,” and “immune control,” the Web of Science Core Collection database was searched for publications on immune control in Kawasaki disease. This bibliometric analysis was carried out using VOSviewers, CiteSpace, and the R package “bibliometrix.”

In total, 294 studies on immune control in Kawasaki disease were published in Web of Science Core Collection. The three most significant institutions were Chang Gung University, the University of California San Diego, and Kaohsiung Chang Gung Memorial Hospital. China, the United States, and Japan were the three most important countries. In this research field, Clinical and Experimental Immunology was the top-referred journal, while the New England Journal of Medicine was the most co-cited journal. The Web of Science Core Collection document by McCrindle BW et al. published in 2017 was the most cited reference. Additionally, the author keywords concentrated on “COVID-19,” “SARS-CoV-2,” and “multisystem inflammatory syndrome in children” in recent years.

The research trends and advancements in immune control in Kawasaki disease are thoroughly summarised in this bibliometric analysis, which is the first to do so. The data indicate recent research frontiers and hot directions, making it easier for researchers to study the immune control of Kawasaki disease.

Failure of the patent ductus arteriosus to close is common among extremely low birth weight neonates and has been associated with increased morbidities. The objective of this study was to compare outcomes between early and late surgical ligation in extremely low birth weight patients.

This was a single-centre retrospective cohort study of infants who required surgical closure of patent ductus arteriosus between January 2017 and August 2022.

A total of 43 neonates were identified with birth weight less than 1 kg that underwent surgical patent ductus arteriosus ligation. Compared to the late ligation group, the early ligation group experienced fewer total days of mechanical ventilation (43.9 days vs. 97.2 days, p < 0.05) and a shorter length of hospital stay (114.2 days vs. 169.0 days, p < 0.05).

Early surgical ligation of haemodynamically significant patent ductus arteriosus in extremely low birth weight neonates may improve hospital morbidity, including improved ventilatory outcomes and a shorter length of stay.

Enteral feeding prior to cardiac surgery has benefits in pre-operative and post-operative patient statuses. In 2020, to increase pre-operative feeding for single-ventricle patients prior to stage 1 palliation, an enteral feeding algorithm was created. The aim of this study is to monitor the impact of our practice change with the primary outcome of necrotising enterocolitis incidence from birth to 2 weeks following surgical intervention.

This is a single-site, retrospective cohort study including patients from 1 March, 2018 to 1 July, 2022. Variables assessed include demographics, age at cardiac surgery, primary cardiac diagnosis, necrotising enterocolitis pre-operative and 2 weeks post-operative cardiac surgery, feeding route, feeding type, volume of trophic enteral feeds, and near-infrared spectroscopy.

Following implementation of a pre-operative enteral feeding algorithm, the rate of neonates fed prior to surgery increased (39.5–75%, p = .001). The feedings included a mean volume of 28.24 ± 11.16 ml/kg/day, 83% fed breastmilk only, 44.4% tube fed, and 55.5% of infants had all oral feedings. Comparing enterally fed neonates and those not enterally fed, the necrotising enterocolitis incidence from birth to 2 weeks post-op was not significantly increased (p = 0.926).

As a result of implementing our feeding algorithm, the frequency of infants fed prior to stage I Norwood or Hybrid surgeries increased to 75%, and there was no significant change in the incidence of necrotising enterocolitis. This study confirmed that pre-operative enteral feeds are safe and are not associated with increased incidence of necrotising enterocolitis.

This study examined the relationship between changes in physical activity and their impact on exercise capacity and health-related quality of life over a 3-year span in patients with CHD.

We evaluated 99 young patients with CHD, aged 13–18 years at the outset. Physical activity, health-related quality of life, and exercise capacity were assessed via questionnaires and peak oxygen uptake measurements at baseline and after 3 years; changes in measures were estimated between the two time points and categorised into quartiles. Participants were stratified according to achieved (active) or not-achieved (inactive) recommended levels of physical activity (≥150 minutes/week) at both time points.

Despite increases in physical activity, exercise capacity, and health-related quality of life over 3 years, the changes were not statistically significant (all p > 0.05). However, a positive association was found between physical activity changes and exercise capacity (ß = 0.250, p = 0.040) and health-related quality of life improvements (ß = 0.380, p < 0.001). Those with the most pronounced physical activity increase showed notable exercise capacity (p < 0.001) and health-related quality of life increases (p < 0.001) compared with patients with the largest decline in physical activity. The active-inactive category demonstrated a notable decline in exercise capacity compared to the active-active group, while the inactive-active group showed health-related quality of life improvements.

Over 3 years, increased physical activity was consistently linked to increases in exercise capacity and health-related quality of life in patients with CHD, highlighting the potential of physical activity augmentation as an intervention strategy.

Familial Mediterranean fever is an autosomal recessive autoinflammatory inherited disease. We aimed to evaluate cardiac involvement in children with familial Mediterranean fever during the attack-free period.

The prospective study included 75 familial Mediterranean fever patients during the attack-free period and 50 healthy children. Cardiac evaluation was performed using electrocardiography, 24-hour ambulatory Holter monitoring, and conventional and tissue Doppler echocardiography. Aortic stiffness indices were calculated.

There were no differences between the groups in age, height, sex, body mass index, and arterial blood pressure parameters (p > 0.05). QT and corrected QT dispersion parameters were similar in both groups (p > 0.05). The E wave velocity and the E/A ratio of the mitral and tricuspid valves decreased, and the A wave velocity of the tricuspid and mitral valve increased in familial Mediterranean fever by the Doppler echocardiography (p < 0.05). The myocardial contraction velocities (Sd), early relaxation velocity (Ed), and Ed/late relaxation velocity (Ad) of both ventricles were decreased in familial Mediterranean fever group, whereas the Ad of both ventricles and the interventricular septum was increased in familial Mediterranean fever group. Aortic strain and distensibility were decreased, and pressure strain elastic modules (Ep), pressure strain normalised (Ep*) by diastolic pressure, and aortic stiffness β index were increased in familial Mediterranean fever patients (p < 0.05). When time domain heart rate variability parameters were evaluated, SDNN-i, RMSSD, and PNN50 significantly decreased in familial Mediterranean fever patients (p < 0.05), whereas SDNN and SDANN were similar in both groups (p > 0.05).

Our findings showed that cardiac involvement could exist in familial Mediterranean fever patients, even during nonattack periods.

The aim of our study was to assess left and right ventricle systolic and diastolic functions in female adolescents with vitamin D deficiency using conventional echocardiography and pulsed-wave tissue Doppler imaging and to investigate carotid intima media thickness and asymmetric dimethylarginine levels.

Sixty-six female adolescents were enrolled in this study. The female adolescents were divided into a vitamin D deficiency group (n: 34) and a control group (n: 32). All subjects underwent laboratory blood tests, including asymmetric dimethyl arginine, complete two-dimensional, pulse, and tissue Doppler echocardiography, and measurement of the carotid intima-media thickness.

The vitamin D-deficient female adolescent group had normal left and right ventricle systolic and diastolic functions and normal global systolic and diastolic myocardial performance. In the patients with vitamin D deficiency, the carotid intima-media thickness was higher than that in the controls. In the patients within the vitamin D deficiency group, vitamin D was found to be positively correlated with magnesium and negatively correlated with phosphorus and left atrial dimension.

The results of this study demonstrate that vitamin D deficiency in female adolescence is associated with normal myocardial geometry and function. Although it has been associated with normal levels of asymmetric dimethyl arginine concentration, high measured carotid intima-media thickness may reflect endothelial dysfunction.

Pregnancy-related physiological adaptations result in increased heart rate as well as electrocardiographic changes such as a mean QTc prolongation of 27 ms. Pregnant women with CHD are at increased risk for cardiovascular complications. The aim of this study was to identify risk factors for abnormally prolonged QTc interval—a risk factor for ventricular arrhythmias—in pregnant women with CHD.

Retrospective longitudinal single-centre study. Pre-pregnancy demographic and electrocardiographic risk factors for abnormal QTc duration during pregnancy of (a) > 460 ms and (b) >27 ms increase were analyzed.

Eighty-three pregnancies in 63 women were included, of which three had documented arrhythmias. All five Modified World Health Organization Classification of Maternal Cardiovascular Risk (mWHO) classes were represented, with 15 pregnancies (18.1%) in mWHO class I, 26 (31.3%) in mWHO II, 28 (33.7%) in mWHO II-III, 11 (13.3%) in mWHO III, and three pregnancies (3.6%) in mWHO class IV. Heart rate and QTc interval increased, while QRS duration and PR interval shortened during pregnancy. QTc duration of > 460 ms was associated with increased pre-pregnancy QTc interval, QRS duration, and weight, as well as body mass index. QTc increase of > 27 ms was associated with increased heart rate prior to pregnancy. No significant associations of electrocardiographic changes with mWHO class or CHD type were identified.

Increased QTc in pregnant women with CHD was associated with being overweight or having higher heart rate, QRS, or QTc duration prior to pregnancy. These patients should be monitored closely for arrhythmias during pregnancy.

I encountered three adult patients with major coronary artery occlusion after Kawasaki disease in childhood, who had developed again acute coronary syndrome of adults in the peripheral branches, such as the 4th segments, the atrioventricular node artery, and the posterior descending artery, of the right coronary artery.

I reviewed their clinical course and coronary angiograms.

Their age at onset of acute coronary syndrome ranged from 29 to 33 years. The male patient with a previous anteroseptal myocardial infarction in children had a symptomatic occlusion of the branch of the 4th posterior descending artery at 32 years of age. Acute coronary syndrome occurred in the area of 4th atrioventricular node artery in two female patients. The collateral arteries from the circumflex artery to the 4th atrioventricular node arteries were not clearly injected. It was suspected that they had developed bilateral giant aneurysms after acute Kawasaki disease. Two patients had an acute myocardial infarction due to thrombotic occlusion in a giant aneurysm of the right coronary artery or the left anterior descending artery, and one patient had an asymptomatic coronary occlusion of the right coronary artery and left anterior descending artery in children.

Occlusion of peripheral coronary arteries in adulthood can occur in patients with multi-vessel disease caused by Kawasaki disease. Recurrent events of acute coronary syndrome can occur in adults, although its prevalence may be low. Careful follow-up in adults is also needed in this population.

In this study, we aimed to evaluate quality of life and parental attitudes in children who underwent an atrial septal defect closure procedure with a transcatheter or surgical method in childhood and whether they continued their lives with similar activities to their healthy peers by comparing the two groups.

Patient forms to define sociodemographic and clinical features, the Questionnaire for Measuring Health-Related Quality of Life in Children and Adolescents (KINDL) to measure the quality of life of children, and the Parent-Child Relationship Test (Parental Attitude Research Instrument) to measure parental attitudes were used.

The groups were similar in terms of age and sex. The mean quality of life scale scores were high in all groups, and there was no statistically significant difference between the scores. Parents of the patients who underwent closure received higher scores from the demographic attitudes and recognition of quality subdimension compared to the parents of the healthy group.

The quality of life of children with atrial septal defect closure was found to be similar to their healthy peers. Additionally, the effects of surgical or percutaneous closure of atrial septal defect on quality of life are similar. Children with atrial septal defect closure perceive their health status as well as their healthy peers, and this perception does not cause any difference in the attitudes and behaviours of families.
