Extracardiac abnormalities in infants with congenital heart disease
Insights
Extracardiac anomalies (ECA) are found in 25% of infants with significant heart disease, often linked to syndromes. These anomalies increase mortality risk in infants with congenital heart disease (CHD).
Area of Science:
- Pediatric Cardiology
- Medical Genetics
- Developmental Biology
Background:
- Extracardiac anomalies (ECA) are frequently observed in infants with congenital heart disease (CHD).
- Approximately 25% of infants evaluated for significant cardiac conditions exhibit ECA.
- Multiple ECA and association with known syndromes are common in affected infants.
Purpose of the Study:
- To investigate the prevalence and types of extracardiac anomalies in infants with congenital heart disease.
- To determine the association between ECA and specific cardiac defects.
- To assess the impact of ECA on mortality in infants with CHD.
Main Methods:
- Retrospective analysis of infants diagnosed with significant cardiac disease within their first year of life.
- Documentation of co-occurring extracardiac anomalies and established syndromes.
- Statistical analysis to correlate ECA presence with specific cardiac defects and mortality rates.
Main Results:
- ECA are present in 25% or more of infants with specific conditions like endocardial cushion defect, patent ductus arteriosus, atrial septal defect, ventricular septal defect, malpositions, tetralogy of Fallot, and complex coarctation.
- Musculoskeletal anomalies and syndrome-associated ECA are most common.
- The presence of ECA significantly elevates mortality risk in infants with CHD.
Conclusions:
- Extracardiac anomalies are a significant comorbidity in infants with congenital heart disease.
- Identifying ECA is crucial for risk stratification and management of infants with CHD.
- The increased mortality associated with ECA highlights the need for comprehensive evaluation in these patients.
Abstract:
Extracardiac anomalies (ECA) occur in 25% of infants seen during the first year of life for significant cardiac disease. Often the ECA are multiple and one third of the affected infants have some established syndrome. In infants with endocardial cushion defect, patent ductus arteriosus, atrial septal defect, ventricular septal defect, malpositions, tetralogy of Fallot, and complex coarctation ECA occur in 25% or more of the cases. The most frequent ECA are in the musculoskeletal system or associated with a specific syndrome. The presence of an ECA significantly increases the mortality in infants with CHD.
