Two-dimensional echocardiography in infants with persistent truncus arteriosus

A B Houston, N L Gregory, E Murtagh

    British Heart Journal
    |November 1, 1981
    PubMed
    Summary

    Two-dimensional echocardiography accurately diagnosed persistent truncus arteriosus in infants. Key indicators included a single great artery with specific branching or valve cusp variations, enabling reliable identification.

    Area of Science:

    • Pediatric Cardiology
    • Congenital Heart Disease
    • Diagnostic Imaging

    Background:

    • Persistent truncus arteriosus is a complex congenital heart defect.
    • Accurate and early diagnosis is crucial for infant outcomes.
    • Echocardiography is a primary non-invasive imaging modality for pediatric cardiac assessment.

    Purpose of the Study:

    • To evaluate the diagnostic utility of two-dimensional echocardiography for persistent truncus arteriosus in infants.
    • To identify specific echocardiographic criteria for diagnosing this condition.

    Main Methods:

    • Consecutive series of 13 infants with suspected persistent truncus arteriosus.
    • Two-dimensional echocardiography was performed on all participants.
    • Analysis focused on the great artery origin, branching patterns, and semilunar valve morphology.

    Main Results:

    • All 13 infants demonstrated a single great artery with an aortic-like course.
    • Branching from the ascending great artery was observed in 10 infants.
    • More than three semilunar valve cusps were identified in 5 infants.
    • These echocardiographic findings led to a correct diagnosis in 12 out of 13 infants.

    Conclusions:

    • Two-dimensional echocardiography is effective in diagnosing persistent truncus arteriosus in neonates and infants.
    • Identifying a single great artery with characteristic branching and/or abnormal semilunar valve cusp number are reliable diagnostic markers.
    • Echocardiographic assessment provides crucial information for managing this severe congenital heart defect.
