Automated Function Imaging (AFI) provides accurate and reproducible global longitudinal strain (GLS) measurements for assessing left ventricular function. This technique is feasible and quick, regardless of operator experience.

Area of Science:

  • Cardiology
  • Medical Imaging
  • Ultrasound Technology

Background:

  • Speckle tracking ultrasound enables segmental strain calculation.
  • Automated Function Imaging (AFI) integrates speckle tracking for rapid left ventricular (LV) function assessment.

Purpose of the Study:

  • Evaluate the feasibility, calculation time, accuracy, and reproducibility of global longitudinal strain (GLS) using AFI.
  • Compare AFI-derived GLS to established echocardiographic and angiographic methods for determining LV function.

Main Methods:

  • Echocardiography performed on 65 patients undergoing cardiac catheterization.
  • Patients categorized into three ejection fraction (EF) groups.
  • GLS analysis from apical views, compared against EF and other LV function parameters.

  • Evaluated by both experienced and novice operators.

    • Main Results:

    • Successful GLS acquisition in 97% of patients.
    • Mean calculation time under 60 seconds.
    • Significant GLS differences across EF groups (p<0.01).
    • Strong correlations between GLS and LV function (r=0.68-0.87) with high reproducibility.
    • No significant difference in results between operators of varying experience.

    Conclusions:

    • AFI is a clinically applicable and effective method for LV function assessment.
    • Short acquisition time, high feasibility, and accuracy are key advantages.
    • Operator experience does not impact the reliability of AFI for GLS measurement.
