Insights
Congenital heart diseases (CHDs) are frequently linked to genetic defects in Rwandan children. Routine echocardiography and genetic testing are recommended for early detection in at-risk pediatric patients.
Area of Science:
- Medical Genetics
- Pediatric Cardiology
- Clinical Genetics
Background:
- Congenital heart diseases (CHDs) are often associated with underlying genetic abnormalities.
- Understanding the prevalence and patterns of CHD in genetically affected pediatric populations is crucial for diagnosis and management.
Purpose of the Study:
- To determine the occurrence and specific patterns of congenital heart disease (CHD) association with genetic defects in pediatric patients in Rwanda.
- To investigate the relationship between genetic defects and the types of CHDs observed in this cohort.
Main Methods:
- Recruited 125 pediatric patients exhibiting clinical signs suggestive of genetic defects.
- Conducted echocardiography to assess cardiac structures and function in all participants.
- Performed standard karyotype analysis to identify chromosomal abnormalities.
Main Results:
- Congenital heart diseases (CHDs) were prevalent in the majority of pediatric patients with identified genetic defects.
- Ventricular septal defect was the most common isolated CHD, frequently observed in cases of Down syndrome.
- Chromosomal abnormalities constituted the majority of genetic diagnoses and were linked to a diverse range of CHDs.
Conclusions:
- Congenital heart diseases (CHDs) are common among Rwandan pediatric patients with genetic defects.
- Routine echocardiography and systematic genetic investigations, including karyotyping, are essential for pediatric patients with suspected CHD and genetic abnormalities.
- Early and comprehensive assessment can improve diagnostic yield and inform clinical management strategies.
Introduction:
Congenital heart diseases (CHD) are commonly associated with genetic defects. Our study aimed at determining the occurrence and pattern of CHD association with genetic defects among pediatric patients in Rwanda.
Methods:
A total of 125 patients with clinical features suggestive of genetic defects were recruited. Echocardiography and standard karyotype studies were performed in all patients.
Results:
CHDs were detected in the majority of patients with genetic defects. The commonest isolated CHD was ventricular septal defect found in many cases of Down syndrome. In total, chromosomal abnormalities represented the majority of cases in our cohort and were associated with various types of CHDs.
Conclusion:
Our findings showed that CHDs are common in Rwandan pediatric patients with genetic defects. These results suggest that a routine echocardiography assessment combined with systematic genetic investigations including standard karyotype should be mandatory in patients presenting characteristic clinical features in whom CHD is suspected to be associated with genetic defect.
