Summary
This summary is machine-generated.

Two speckle-tracking software systems for cardiac ultrasound show comparable results in assessing left ventricular function in healthy individuals. Global longitudinal strain is more reliable than radial or circumferential strain across different systems.

Area of Science:

  • Cardiology
  • Medical Imaging
  • Echocardiography

Background:

  • Two-dimensional (2D) speckle echocardiography is crucial for assessing left ventricular function.
  • Myocardial strain analysis, a key component of echocardiography, can be performed using various speckle-tracking software.
  • Variability in software may impact the accuracy of myocardial strain measurements.

Purpose of the Study:

  • To compare the performance of two commercial cardiac ultrasound systems and their proprietary speckle-tracking software.
  • To evaluate the quantification of global myocardial strain in a healthy population using different systems.
  • To determine the comparability of GE Vivid 7 and Toshiba Artida 4D systems for strain analysis.

Main Methods:

  • Twenty-eight healthy subjects underwent two 2D echocardiograms using GE Vivid 7 and Toshiba Artida 4D systems.
  • Global longitudinal, radial, and circumferential strain were analyzed using manufacturer-specific software (EchoPac PC and 2D Wall Motion Tracking).
  • Bland-Altman analysis assessed agreement between the two systems for strain quantification.

Main Results:

  • No significant differences were found in global longitudinal, radial, or circumferential strain values between the GE and Toshiba systems (P = NS).
  • Limits of agreement were narrower for global longitudinal strain (-2.25 to 3.65) compared to radial (-2.23 to 12.44) and circumferential strain (-1.36 to 10.54).
  • Left ventricular ejection fraction averaged 59 +/- 7% across subjects.

Conclusions:

  • Commercially available speckle-tracking software demonstrates comparable performance in quantifying left ventricular function in healthy individuals.
  • Global longitudinal strain is a more robust and reliable parameter than radial or circumferential strain when using different cardiac ultrasound systems.
  • These findings support the use of global longitudinal strain for consistent myocardial function assessment across various echocardiography platforms.
