Factors Influencing Weight Gain at Different Stages of the Fontan Pathway for Children with Functionally Single Ventricle Heart Disease
To investigate the change in standardized weight-for-age z-score (WAZ) and explore clinical and demographic factors influencing weight changes in children with functionally single ventricle hearts (f-SV) undergoing the Fontan surgical pathway.
Approach:
Data Collection: Included children who had surgical or interventional catheter procedures, with survival status obtained from the UK Office for National Statistics. Specific variables collected included weight, age, and surgical stage.
Key Findings:
Weight and height z-scores decrease sharply from birth to S2 but improve post-procedure.
Weight normalizes around 10-12 years after Fontan surgery, while height gain is often lower, increasing obesity risk.
Growth faltering is common in infants with f-SV due to multiple factors including inadequate intake and higher metabolic expenditure.
Interpretation:
The study highlights the importance of understanding factors influencing weight changes in children with f-SV during the Fontan surgical pathway.
Limitations:
The NCHDA dataset does not include patients who have never had surgical procedures.
Exclusion of children without complete weight data at all surgical stages may limit the generalizability of findings.
Conclusion:
Understanding modifiable factors affecting weight gain in f-SV patients can inform clinical management strategies.
From Medicare payment updates to drug approvals and device access, these federal actions may affect reimbursement, prescribing, patient access, and clinical workflows.
