    M-mode echocardiography remains valuable in adult cardiac practice. Two-dimensional echocardiography offered limited additional diagnostic contribution in most reviewed cases.

    Area of Science:

    • Cardiology
    • Medical Imaging

    Background:

    • Echocardiography is a cornerstone of cardiac diagnostics.
    • The comparative diagnostic utility of M-mode versus two-dimensional echocardiography in routine adult practice requires ongoing evaluation.

    Purpose of the Study:

    • To retrospectively assess the diagnostic contribution of two-dimensional echocardiography compared to M-mode echocardiography in adult patients.
    • To determine the continued relevance of M-mode echocardiography in contemporary cardiology.

    Main Methods:

    • Retrospective review of 300 consecutive M-mode and two-dimensional echocardiograms.
    • Independent assessment by two observers on the diagnostic value of each modality.
    • Patient population included ambulatory and hospitalized adults in a community hospital setting.

    Main Results:

    • Two-dimensional echocardiography provided no additional diagnostic information in 75% of cases reviewed.
    • The diagnostic contribution of two-dimensional echocardiography was deemed important or essential in only 20% of cases.
    • M-mode echocardiography demonstrated significant utility across the majority of reviewed examinations.

    Conclusions:

    • M-mode echocardiography continues to hold significant value in everyday adult cardiac practice.
    • The incremental diagnostic benefit of routine two-dimensional echocardiography over M-mode echocardiography in this cohort was limited.
    • M-mode echocardiography remains a cost-effective and essential tool for cardiac assessment.
