    M-mode echocardiography quantifies left ventricular ejection fraction despite limitations in accuracy and applicability. Nevertheless, a cubed function or correction formula allows calculation for specific left ventricular conditions.

    Area of Science:

    • Cardiology
    • Medical Imaging
    • Echocardiography

    Background:

    • Left ventricular ejection fraction (LVEF) is a key metric in cardiac function assessment.
    • M-mode echocardiography is commonly used for LVEF quantification.
    • Existing methods for LVEF calculation have known limitations.

    Purpose of the Study:

    • To evaluate the utility of M-mode echocardiography for LVEF quantification.
    • To address the limitations of M-mode echocardiography in LVEF calculation.
    • To present a method for calculating LVEF in specific left ventricular conditions.

    Main Methods:

    • Utilized M-mode echocardiography for left ventricular measurements.
    • Applied a cubed function or correction formula for LVEF calculation.

  • Focused on symmetrically contracting, normally sized, and enlarged left ventricles.

    • Main Results:

    • M-mode echocardiography provides a frequently used method for LVEF quantification.
    • Limitations include accurate short-axis measurement, geometric assumptions, and applicability to asynergic ventricles.
    • A cubed function or correction formula enables LVEF calculation in specific scenarios.

    Conclusions:

    • Despite limitations, M-mode echocardiography remains a practical tool for LVEF assessment.
    • The proposed formula enhances LVEF calculation accuracy for certain left ventricular morphologies.
    • Further investigation may refine LVEF quantification in complex cardiac conditions.
