Congenital heart disease in Ceylon
Insights
Interatrial septal defect is the most common congenital heart disease in Ceylon. This study analyzed 555 cases, finding variations in defect prevalence by age group.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Public Health
Background:
- Congenital heart disease (CHD) represents a significant global health burden.
- Understanding the epidemiological patterns of CHD is crucial for targeted interventions.
- Previous studies on CHD prevalence have primarily focused on Western populations.
Purpose of the Study:
- To determine the prevalence and distribution of various congenital heart disease types in a Sri Lankan population.
- To compare the findings with international data on CHD epidemiology.
Main Methods:
- Retrospective analysis of 555 consecutive cases of congenital heart disease.
- Data collected from patients in Ceylon (now Sri Lanka).
- Categorization of cardiac lesions and age-specific analysis.
Main Results:
- Interatrial septal defect was the most frequent cardiac lesion overall.
- Interventricular septal defect and persistent ductus arteriosus were the next most common.
- Interventricular and interatrial septal defects showed equal prevalence in patients under 16, with interventricular defects being most common under 11.
- Persistent truncus arteriosus was unusually common, while coarctation of the aorta and congenital aortic stenosis were rare.
Conclusions:
- The epidemiological profile of congenital heart disease in Sri Lanka differs from that reported in other regions.
- Specific lesions like persistent truncus arteriosus show a higher prevalence, necessitating further investigation.
- Age-specific analysis reveals distinct patterns in septal defects.
Abstract:
An analysis of 555 consecutive cases of congenital heart disease in Ceylon has shown that for the whole series interatrial septal defect is the commonest cardiac lesion; next is interventricular septal defect, followed by persistent ductus arteriosus. Interventricular and interatrial septal defects are equally common among all the patients below 16 years of age, but interventricular septal defects are commonest among those below 11 years. Persistent truncus arteriosus is unusually common, while coarctation of the aorta and congenital aortic stenosis are rare, as compared with series reported from other places.
