Aortic diameters in infants and young children: normative angiographic data

Area of Science:

• Pediatric Cardiology
• Medical Imaging
• Vascular Biology

Background:

• Accurate aortic diameter measurements are crucial for diagnosing and managing pediatric cardiovascular conditions.
• Normative data is essential for interpreting individual patient measurements in the context of normal growth and development.

Purpose of the Study:

• To establish normative cineangiographic measurements for key segments of the aorta in infants and children.
• To provide reference data for assessing aortic dimensions in pediatric patients with and without congenital heart disease.

Main Methods:

• Cineangiographic measurements of the ascending aorta, arch, isthmus, postisthmic region, and descending aorta were performed.
• Measurements were taken in the left anterior oblique view.
• Data was collected from 18 healthy children and 47 children with congenital heart disease not involving the aorta.

Main Results:

• Normative diameter data for various aortic segments were tabulated.
• Results were stratified by age and body surface area.
• The data allows for comparison of individual measurements against established norms.

Conclusions:

• The study provides valuable normative data for pediatric aortic dimensions.
• This data aids in the clinical assessment of aortic size variations in children.
• The findings support the use of cineangiography for evaluating aortic development and disease.
