[The incidence of heart defects in children]
Insights
This study analyzed congenital heart disease in 91,823 children born in Bohemia in 1980. Congenital heart disease affected 6.4% of newborns, with ventricular septal defect being the most common.
Area of Science:
- Pediatric Cardiology
- Epidemiology
- Public Health
Context:
- A comprehensive birth cohort from Bohemia (n=91,823) born in 1980 was analyzed.
- Congenital heart disease (CHD) is a significant global health concern.
- Understanding the prevalence and types of CHD is crucial for early intervention and management.
Purpose:
- To determine the prevalence and incidence of congenital heart disease and cardiomyopathy in a large birth cohort.
- To identify the most common types of congenital heart defects in this population.
Summary:
- Congenital heart disease was diagnosed in 6.415/1000 liveborns, and cardiomyopathy in 0.261/1000 liveborns.
- Ventricular septal defect (31.4%) was the most prevalent heart defect, followed by atrial septal defect (11.4%) and aortic stenosis (7.6%).
- 1.808/1000 liveborns initially diagnosed with CHD showed no detectable defect by age 4.
Impact:
- Provides crucial epidemiological data on congenital heart disease in a specific population.
- Highlights the importance of accurate diagnosis and long-term follow-up for pediatric cardiac conditions.
- Informs public health strategies and resource allocation for managing congenital heart defects.
Abstract:
By examining all of 91,823 children born in 1980 in Bohemia, congenital heart disease was proved in 589 (6.415/1000 liveborns) and cardiomyopathy in 24 (0.261/1000 liveborns). Further 166 (1.808/1000 liveborns) were follow-up with a diagnosis of congenital heart disease by pediatric cardiologists in the field, but at the age of 4 years we didn't prove the defect any more. Prevalence of heart defects: ventricular septal defect (31.4%), atrial septal defect (11.4%), aortic stenosis (7.6%), pulmonary stenosis (7.1%), coarctation of the aorta (5.8%), transposition of the great arteries (5.4%), patent ductus arteriosus (4.8%), atrioventricular canal and hypoplastic left heart (4.1%), tetralogy of Fallot (3.6%). Other defects occurred less frequently than in 2.5% of all congenital heart disease.
