    Area of Science:

    • Veterinary Cardiology
    • Diagnostic Imaging

    Background:

    • Echocardiography is a valuable non-invasive tool for cardiac assessment.
    • Swine models are frequently used in cardiovascular research.

    Purpose of the Study:

    • To evaluate the utility of M-mode echocardiography for assessing cardiac structure and function in clinically normal pigs.
    • To compare echocardiographic findings with invasive measurements.

    Main Methods:

    • M-mode echocardiograms were acquired from anesthetized pigs in left lateral recumbency.
    • Measurements included internal minor axis diameter, contractility index (Vcf), caudal wall thickness, and aortic root dimension.
    • Echocardiographic data were corroborated with cineangiographic and postmortem studies.

    Main Results:

    Related Experiment Videos

    • Echocardiography provided reliable measurements of cardiac dimensions and contractility.
    • Comparison with other methods showed minimal differences (≤2 mm).
    • The technique is convenient for restrained, mature swine.

    Conclusions:

    • M-mode echocardiography is a reliable, non-invasive method for obtaining cardiovascular data in swine.
    • This technique offers a safe and cost-effective alternative to invasive procedures for research and clinical applications.
