Superior Performance in Prone in Infants With Congenital Heart Disease Predicts an Earlier Onset of Walking

Optimising motor development in the hospitalised infant with CHD: factors contributing to early motor challenges and recommendations for assessment and intervention

BACKGROUND

Neurodevelopmental challenges are the most prevalent comorbidity associated with a diagnosis of critical CHD, and there is a high incidence of gross and fine motor delays noted in early infancy. The frequency of motor delays in hospitalised infants with critical CHD requires close monitoring from developmental therapies (physical therapists, occupational therapists, and speech-language pathologists) to optimise motor development. Currently, minimal literature defines developmental therapists' role in caring for infants with critical CHD in intensive or acute care hospital units.

PURPOSE

This article describes typical infant motor skill development, how the hospital environment and events surrounding early cardiac surgical interventions impact those skills, and how developmental therapists support motor skill acquisition in infants with critical CHD. Recommendations for healthcare professionals and those who provide medical or developmental support in promotion of optimal motor skill development in hospitalised infants with critical CHD are discussed.

CONCLUSIONS

Infants with critical CHD requiring neonatal surgical intervention experience interrupted motor skill interactions and developmental trajectories. As part of the interdisciplinary team working in intensive and acute care settings, developmental therapists assess, guide motor intervention, promote optimal motor skill acquisition, and support the infant's overall development.

A family-tailored early motor intervention (EMI-Heart) for infants with complex congenital heart disease: study protocol for a feasibility RCT

BACKGROUND

Children with congenital heart disease (CHD) undergoing open-heart surgery are at risk for developmental impairments with motor delay manifesting first and contributing to parental concerns. Only a few interventional studies aim to improve neuromotor development in infants with CHD with inconclusive results. We thus developed a family-tailored early motor intervention (EMI-Heart), which aims to promote motor development and family well-being in the first year of life after open-heart surgery. The primary aim described in this protocol is to evaluate feasibility of EMI-Heart. The secondary aim is to describe the difference between the intervention and control group in motor outcomes and family well-being at baseline, post-treatment, and follow-up.

METHODS

This prospective, parallel single-center feasibility randomized controlled trial (RCT) will compare EMI-Heart with standard of care in infants with complex CHD. Sixteen infants and their families, randomly allocated to EMI-Heart or the control group, will participate within the first 5 months of life. Infants assigned to EMI-Heart will receive early motor intervention for 3 months. The intervention's key is to promote infants' postural control to enhance motor development and partnering with parents to encourage family well-being. Feasibility outcomes will be (a) clinical recruitment rate and percentage of families completing EMI-Heart, (b) average duration and number of sessions, and (c) acceptability of EMI-Heart using a parental questionnaire post-treatment, and descriptive acceptability of EMI-Heart to the pediatric physiotherapist. Secondary outcomes of the intervention and control group will be infants' motor outcomes and questionnaires assessing family well-being at 3-5 months (baseline), at 6-8 months (post-treatment), and at 12 months of age (follow-up). We will evaluate feasibility using descriptive statistics. Non-parametric statistical analysis of secondary outcomes will assess differences between the groups at baseline, post-treatment, and follow-up.

DISCUSSION

This feasibility RCT will provide information about a newly developed family-tailored early motor intervention in infants with complex CHD. The RCT design will provide a foundation for a future large-scale interventional trial for infants with CHD after open-heart surgery.

TRIAL REGISTRATION

This study protocol (version 1.3, 01.02.2022) was approved by the Cantonal Ethics Commission Zurich (BASEC-Nr. 2019-01,787) and is registered by Clinicaltrials.gov (NCTT04666857).

Longitudinal Motor-Developmental Outcomes in Infants with a Critical Congenital Heart Defect

Infants with critical congenital heart defects (CCHDs) are at increased risk for neurodevelopmental delays. The early identification of motor delays is clinically relevant to prevent or reduce long-term consequences. The current study aims to describe the motor-developmental pathways of infants with a CCHD. Motor development was assessed in 215 infants and toddlers using the Dutch version of the Bayley-III. At 3 months (n = 165), 9 months (n = 188), and 18 months (n = 171) the motor composite scores were 97, 98, and 104, respectively. A motor composite score of ≤−2 SD was only seen in 2.4%, 0%, and 2.3%, respectively, with gross motor deficits being observed more often than fine motor deficits (12% vs. 0% at 18 months). Over 90% of infants who scored average at 9 months still did so at 18 months. The majority of infants with below-average gross motor scores (≤−1) at 9 months still had a below-average or delayed motor score (≤−2 SD) at 18 months. Abnormal gross motor scores (≤−2 SD) increased with age. Infants with single-ventricle physiology performed significantly (p ≤ 0.05) worse on both fine and gross motor skills at 9 and 18 months compared to infants with other CCHDs.

Motor Developmental Delay After Cardiac Surgery in Children With a Critical Congenital Heart Defect: A Systematic Literature Review and Meta-analysis

PURPOSE

To systematically review evidence regarding the severity and prevalence of motor development in children with a critical congenital heart defect (CCHD) without underlying genetic anomalies.

SUMMARY OF KEY POINTS

Twelve percent of all included studies reported abnormal mean motor developmental scores, and 38% reported below average motor scores. Children with single-ventricle physiology, especially those with hypoplastic left heart syndrome, had the highest severity and prevalence of motor delay, particularly at 0 to 12 months. Most included studies did not differentiate between gross and fine motor development, yet gross motor development was more affected.

RECOMMENDATIONS FOR CLINICAL PRACTICE

We recommend clinicians differentiate between the type of heart defect, fine and gross motor development, and the presence of genetic anomalies. Furthermore, increased knowledge about severity and prevalence will enable clinicians to tailor their interventions to prevent motor development delays in CCHD.

Prenatal markers of atypical neurodevelopment in children with congenital heart defects

BACKGROUND

A growing body of literature demonstrates that survivors of congenital heart defects (CHD) are at increased risk of neurodevelopmental delay, which frequently manifests as motor delay during the first year of life.

OBJECTIVE

The aim of this study was to determine prenatal predictors of an early atypical neurodevelopment. This information could help assist decision-making during prenatal counseling.

STUDY DESIGN

In this retrospective cohort study, we evaluated the records of 75 children with CHD followed at the Clinique d'Investigation Neuro-Cardiaque (CINC) of the CHU Ste-Justine born between 2013 and 2016. The neurodevelopmental outcome was determined using the Alberta Infant Motor Scale (AIMS) at 4 months. Associations between prenatal factors and atypical neurodevelopment (AIMS < 10th percentile) were assessed using bivariate and multivariate analyses.

RESULTS

Forty-four infants (58.7%) had atypical neurodevelopment. When there was no extra cardiac anomaly seen on prenatal ultrasound, a head to abdominal ratio (HC/AC) below 1.1 was associated with a four-fold increased risk of atypical neurodevelopment (OR = 4.54; 95% CI = 1.24-16.64 p = .023). There was no difference in identified genetic anomaly in both groups. However, there was a trend toward more extra cardiac anomalies in infants with atypical neurodevelopment (27.3%) compared to 9.7% in those with typical neurodevelopment (p = .061).

CONCLUSION

Our study shows that early atypical neurodevelopment affects the majority of children with CHD and highlights the importance of post-natal monitoring by a specialized team. A thorough prenatal ultrasound is important to screen for those at higher risk i.e. those with extra cardiac anomaly and HC/AC below 1.1. A larger cohort is needed to validate those results.

Gross Motor Development of Children with Congenital Heart Disease Receiving Early Systematic Surveillance and Individualized Intervention: Brief Report

Purpose: This retrospective study aims to describe the gross motor development of children aged 4 to 24 months with congenital heart disease (CHD) enrolled in a systematic developmental follow-up program and to describe the frequency of physical therapy sessions they received between 4 and 8 months of age. Methods: Twenty-nine infants with CHD underwent motor evaluations using the AIMS at 4 months, and the Bayley-III at 12 and 24 months. Results: Based on AIMS, 79% of 4-month-old infants had a gross motor delay and required physical therapy. Among these, 56.5% received one to two physical therapy sessions, and 43.5% received three to six sessions. Infants who benefited from regular interventions tended to show a better improvement in motor scores from 12 to 24 months. Conclusion: This study highlights the importance of early motor screening in infants with CHD and suggests a potential benefit of early physical therapy in at-risk children.

Sternal Precautions and Prone Positioning of Infants Following Median Sternotomy: A Nationwide Survey

PURPOSE

To describe current practice of pediatric sternal precautions (PSPs) and prone positioning restrictions (PPRs) in infants after median sternotomy.

METHODS

A Web-based survey with 21 questions was developed on the basis of a review of current literature and expert consultation. Snowball sampling resulted in 68 participants well represented by profession throughout the United States.

RESULTS

Approximately 80% of participants reported having institutional protocols for PSPs. Most common reported PSPs were no lifting at the axillae and no pulling of arms to achieve sitting. PSPs also included PPRs. The opinions of participants supported no PPRs or modified PPRs compared with strict PPRs.

CONCLUSIONS

Types of PPRs varied across participants, with the majority of participants in favor of modified PPRs while PSPs were less varied. Research is needed to examine the effects of PSPs and PPRs in infants post-median sternotomy.

Impacts of an Interdisciplinary Developmental Follow-Up Program on Neurodevelopment in Congenital Heart Disease: The CINC Study

Objectives: This study investigates the impact of an early systematic interdisciplinary developmental follow-up and individualized intervention program on the neurodevelopment of children with complex congenital heart disease (CHD) who required cardiac surgery. Study Design: We prospectively enrolled 80 children with CHD: 41 were already followed at our neurocardiac developmental follow-up clinic from the age of 4 months, while 39 were born before the establishment of the program and therefore received standard health care. We conducted cognitive, motor, and behavioral assessments at 3 years of age. We used one-way multivariate analyses of variance to compare the neurodevelopmental outcome of both groups. Results: Between-group analyses revealed a distinct neurodevelopmental profile with clinically significant effect size (P < 0.001, partial η² = 0.366). Children followed at our clinic demonstrated better receptive language performances (P = 0.048) and tended to show higher scores on visuo-constructive tasks (P = 0.080). Children who received standard health care exhibited greater performances in working memory tasks (P = 0.032). We found no group differences on global intellectual functioning, gross and fine motor skills, and behaviors. Referral rates for specific remedial services were higher in patients followed at our neurocardiac clinic compared to the historical cohort (P < 0.005). Conclusions: Overall, the impact of the developmental follow-up and individualized intervention program on neurodevelopmental outcomes remains subtle. Nevertheless, results, although limited by several factors, point toward an advantage for the children who took part in the program regarding receptive language skills over children who received standard health care. We hypothesize that group differences may be greater with growing age. Further research involving larger cohorts is needed to clearly assess the effectiveness of neurocardiac developmental follow-up programs at school age.

Recent advances in our understanding of neurodevelopmental outcomes in congenital heart disease

PURPOSE OF REVIEW

Patients with congenital heart disease (CHD) suffer from a pattern of neurodevelopmental abnormalities including deficits in language and executive function. In this review, we summarize recent studies that examine these outcomes, their risk factors, possible biomarkers, and attempts to develop therapeutic interventions.

RECENT FINDINGS

The latest literature has highlighted the role of genetics in determining neurologic prognosis, as we have increased our understanding of potentially modifiable perioperative risk factors. The role of potentially neurotoxic medical therapies has become more salient. One recent focus has been how neurodevelopment affects quality of life and leads to a high prevalence of mental illness. Neuroimaging advances have provided new insights into the pathogenesis of deficits.

SUMMARY

Although many risk factors in CHD are not modifiable, there is promise for interventions to improve neurodevelopmental outcomes in patients with CHD. Biomarkers are needed to better understand the timing and prognosis of injury and to direct therapy. Research into psychosocial interventions is urgently needed to benefit the many survivors with CHD.
