Summary

This study compared M-mode echocardiographic methods for assessing left ventricular mass (LVM). The Devereux and Reichek method showed the highest correlation with anatomical LVM, making it a reliable diagnostic tool.

Area of Science:

  • Cardiology
  • Medical Imaging

Background:

  • Accurate assessment of left ventricular mass (LVM) is crucial in cardiovascular diagnostics.
  • M-mode echocardiography is a common imaging modality for evaluating cardiac structure.

Purpose of the Study:

  • To compare multiple M-mode echocardiographic methods for quantifying left ventricular mass (LVM).
  • To identify the most accurate M-mode echocardiographic method for LVM assessment against anatomical standards.

Main Methods:

  • Twenty-one subjects underwent M-mode echocardiography.
  • Six different M-mode echocardiographic methods were evaluated.
  • Anatomical left ventricular mass served as the gold standard for comparison.

Main Results:

Related Experiment Videos

  • The Devereux and Reichek (1977) M-mode echocardiographic method demonstrated the strongest correlation (r = 0.99) with anatomical LVM.
  • This method yielded a standard deviation of 49.54 g.
  • The formula derived is LVM = 1.4 [(LVIDd + LVPWTd + IVSTd)3 - (LVIDd)3] - 14 g.

    • Conclusions:

    • The Devereux and Reichek method is a highly accurate M-mode echocardiographic technique for estimating left ventricular mass.
    • This validated method can be reliably used in clinical practice for LVM assessment.
