Insights
This study establishes normal echocardiographic reference values for 186 healthy children, providing essential data for pediatric cardiology. These findings aid in diagnosing cardiac conditions in children based on body weight and surface area.
Area of Science:
- Pediatric Cardiology
- Diagnostic Imaging
- Biometry
Context:
- Echocardiography is crucial for assessing pediatric cardiac health.
- Establishing normative data is essential for accurate diagnosis in children.
- Previous studies may lack comprehensive data across a wide pediatric age range.
Purpose:
- To establish comprehensive two-dimensional echocardiographic reference ranges for healthy children aged 0-18 years.
- To correlate cardiac measurements with body weight and body surface area.
- To provide a normative database for pediatric cardiac assessment.
Summary:
- 186 healthy children (birth to 18 years) underwent two-dimensional echocardiography.
- Measurements included cardiac chamber dimensions, valve annulus widths, great vessel diameters, and ventricular function.
- Regression equations and mean values +/- 2 standard deviations were calculated relative to body weight and surface area.
Impact:
- Provides essential normative data for pediatric echocardiography interpretation.
- Facilitates early and accurate diagnosis of pediatric cardiac abnormalities.
- Supports clinical decision-making in pediatric cardiology and cardiovascular research.
Abstract:
The authors examined by two-dimensional echocardiography a group of 186 healthy children from birth to the age of 18 years. From the assembled records they measured the following: the inner diameter of the inferior vena cava, the diameter of the abdominal aorta, the area of the right and left atrium at the end of systole, the width of the ring of the tricuspid and mitral valve at the end of diastole, the area of the right and left ventricle at the end of systole and its circumference, the width of the annulus of the pulmonary artery, the diameter of the aortic arch, the diameter of the right and left branch of the pulmonary artery. The systolic function of the left ventricle and the curvature of the ventricular septum during systole was calculated from the assessed parameters of the left ventricle. By means of a computer the regression equations of the relation of assessed echocardiographic parameters and body weight and body surface were calculated as well as their mean values +/- 2 standard deviations for the given body weight and body surface which are considered normal for the child population.
