Long-term early development research in congenital heart disease (LEADER-CHD): a study protocol for a prospective cohort observational study investigating the development of children after surgical correction for congenital heart defects during the first 3 years of life

Neurodevelopmental Assessment in Children With Congenital Heart Disease by Applying the Denver Developmental Screening Test 2: A Prospective Cross-Sectional Study

Background Congenital heart conditions often cause developmental delays and impact neurodevelopment throughout one's lifetime. Hence, it is crucial to analyze the impact that heart defects have on the developing brain of a child. The present cross-sectional study was undertaken given the paucity of studies on the developmental status in children with congenital heart diseases (CHDs) in central India, where we tried to evaluate and compare the prevalence of neurodevelopmental delay in individuals with different congenital cardiac disorders. The objectives of our study were, firstly, to utilize the Denver Developmental Screening Test 2 (DDST-2) to evaluate the neurodevelopmental conditions in children with CHD; secondly, to compare the neurodevelopmental state of children with acyanotic CHD (ACHD) and cyanotic CHD (CCHD); and thirdly, to ascertain the prevalence of developmental delay in children with CHD. Methodology The study population comprised children aged six months to six years with two-dimensional (2D) echocardiography confirmation of CHD; those who were critically ill, had genetic syndromes, and were not willing to participate in the study were excluded. The neurodevelopmental assessment was conducted using the DDST-2. The screening looked at each patient's progress in four areas: personal-social, fine motor-adaptive, language, and gross motor. Based on these observations, results were obtained and interpreted. Result Out of 82 children with CHD, the prevalence rate of developmental delay according to the DDST-2 was found to be maximum in the gross motor domain and the least affected in the social domain, which was similar to the analysis of developmental delay by developmental quotient (DQ). The comparative analysis of developmental delay in ACHD and CCHD according to the DDST-2 showed a significant P value only in the gross motor domain. Conclusion The DDST-2 is a straightforward screening tool for determining how well-developed infants with CHD are. The gross motor domain is the most frequently damaged in ACHD and CCHD, followed by the fine motor domain, and the social domain is the least affected. Cyanotic CHD patients are more susceptible to developmental delay than children with ACHD.

Growth and development of children under 5 years of age with tetralogy of Fallot in a Chinese population

Congenital Heart Defects (CHDs) are associated with different patterns of malnutrition and growth retardation, which may vary worldwide and need to be evaluated according to local conditions. Although tetralogy of Fallot (TOF) is one of the first described CHDs, the etiology outcomes in growth and development of TOF in early age child is still unclear in most cases. This study was designed to investigate the growth retardation status of Chinese pediatric TOF patients under 5 years old. The body height, body weight and body mass index (BMI) of 262 pediatric patients (138 boys and 124 girls) who underwent corrective surgery for TOF between 2014 and 2018 were measured using conventional methods. The average body height, body weight and BMI of the patients were significantly lower than WHO Child Growth Standards, while the most affected was body height. Meanwhile, higher stunting frequency and greater deterioration of both the body height and weight happened in elder age (aged 13-60 months) rather than in infant stage (aged 0-12 months) among these patients. Our results confirmed that intervention should be given at early age to prevent the growth retardation of TOF patients getting severer.

Chinese Parents' Perceptions, Attitudes, and Treatment-Seeking Intentions Toward Congenital Heart Disease with Charitable Assistance: A Cross-Sectional Study in a Congenital Heart Center in Southern China

OBJECTIVE

To investigate the perceptions, attitudes and treatment-seeking intentions of Chinese parents toward charitable assistance for congenital heart disease (CHD).

METHODS

This was a cross-sectional study, and different questionnaires were used. Data on Chinese parents' perceptions, attitudes, and treatment-seeking intentions toward charitable assistance for CHD were collected and analyzed.

RESULTS

A total of 220 parents of children with CHD were included in the survey, and 201 completed the survey. The results showed that the perception rate of charity assistance for CHD was only 44.8%, and the channels of understanding were narrow. The majority of participants (98.0%) approved of charitable assistance. A total of 79.1% of the parents thought that charity assistance would improve their treatment-seeking intentions, and 62.7% of the parents answered that it would affect their medical institutions' choice. The results also showed that higher treatment-seeking intention was significantly correlated with higher income and charitable assistance but not with the parents' education level. Correlation analysis found that parents with different monthly incomes and charitable assistance had statistically significant treatment-seeking intentions. Analyzing the factors of surgical treatment in our hospital, it was found that charitable assistance was an essential factor influencing them to choose treatment.

CONCLUSION

Many Chinese parents of patients with CHD did not know about charity assistance, but most of them approved the project. Charitable assistance could improve parents' treatment-seeking intentions.

First steps to a clinical research unit for developmental research in paediatric cardiology: conception and progress of the LEADER project (Long Term Early Development Research) in CHD

OBJECTIVE

We developed the Long-term Early Development Research (LEADER) project to investigate the development of children with CHD and/or after cardiopulmonary resuscitation. Both populations are at risk for delays in motor, cognitive, and language development. However, few studies to date have investigated the longitudinal development in these children.

METHODS

To establish a clinical research unit, we planned three studies: a cross-sectional study in children after cardiopulmonary resuscitation (LEADER-REA Pilot Study), a longitudinal study in children after cardiopulmonary resuscitation, with a focus on evaluating various biomarkers as predictors for developmental outcome (LEADER-CPR study), and a longitudinal study in children with ventricular septal defect, tetralogy of Fallot, or transposition of the great arteries after cardiac surgery (LEADER-CHD study).

RESULTS

Implementation of all three LEADER studies was successful and study protocols were conducted as planned. Findings from the LEADER-REA Pilot study have been recently published and data collection for both prospective trials is ongoing. Descriptive analysis of the first 20 assessments of the LEADER-CHD study showed no severe deficits in overall cognitive, motor, and language developments in the children.

CONCLUSIONS

Children with CHD and/or after cardiopulmonary resuscitation are at risk for developmental delay. Therefore, a detailed developmental assessment is necessary as a pre-requisite for individual developmental support. Our LEADER project has been shown to be feasible in a clinical setting and is the first step towards the establishment of a clinical research unit in our clinic with a focus on longitudinal research.
