Normal aortic root dimensions in premature infants.

M D Reller, R A Meyer, S Kaplan

    Journal of Clinical Ultrasound : JCU
    |May 1, 1983
    PubMed
    Summary

    Normal aortic root dimensions in premature infants were established using echocardiograms. Aortic root diameter increased with infant weight, from 0.53 cm in smaller infants to 0.80 cm in larger premature infants.

    Area of Science:

    • Pediatric Cardiology
    • Neonatal Medicine
    • Diagnostic Imaging

    Background:

    • Establishing normal reference ranges for cardiovascular structures is crucial for diagnosing congenital heart disease and monitoring growth in neonates.
    • Premature infants present unique physiological challenges, necessitating specific dimensional standards.

    Purpose of the Study:

    • To define normal aortic root dimensions in premature infants based on gestational age and weight.
    • To provide reference data for the accurate assessment of aortic root size in this vulnerable population.

    Main Methods:

    • Retrospective analysis of 334 sequential echocardiograms.
    • Inclusion of 111 premature infants with birth weights ranging from 600 to 2500 grams.
    • Measurement of aortic root diameter using standard echocardiographic techniques.

    Main Results:

    • A statistically significant increase in aortic root diameter was observed with increasing infant weight.
    • Aortic root diameter ranged from 0.53 cm ± 0.04 cm for infants weighing 600-900 g.
    • Aortic root diameter reached 0.80 cm ± 0.08 cm for infants weighing 2200-2500 g.

    Conclusions:

    • Normal aortic root dimensions in premature infants correlate directly with body weight.
    • These findings establish essential reference values for echocardiographic evaluation of premature neonates.
    • This data aids in the early detection of aortic root abnormalities in high-risk infant populations.
