Area of Science:

  • Veterinary Cardiology
  • Diagnostic Imaging
  • Animal Physiology

Background:

  • Echocardiography is crucial for evaluating cardiac function.
  • Standardized protocols are needed for reliable cardiac assessments in calves.
  • Limited data exists on the comprehensive echocardiographic evaluation of healthy young cattle.

Purpose of the Study:

  • To establish a standardized echocardiographic protocol for calves.
  • To assess the repeatability and reliability of 51 cardiac variables.
  • To validate in vivo echocardiographic measurements against post-mortem data.

Main Methods:

  • A standardized echocardiographic protocol was applied to 18 healthy calves.
  • Measurements of 51 anatomical and functional cardiac variables were taken.

Related Experiment Videos

  • Two-dimensional and M-mode echocardiography were utilized in long and short axis views.

    • Main Results:

    • Most of the 51 measured cardiac variables demonstrated high repeatability within 24 hours.
    • A close correlation was found between post-mortem and in vivo echocardiographic measurements.
    • Echocardiographic values showed consistency across different scanning planes and ultrasonic modes.

    Conclusions:

    • Quantitative echocardiography is a reliable and repeatable diagnostic technique in calves.
    • The established protocol provides a foundation for future cardiac research in cattle.
    • In vivo echocardiographic measurements are accurate and comparable to post-mortem findings.
