    The Left Atrioventricular Coupling Index (LACI) assesses left atrial and ventricular diastolic function and shows prognostic value.

  • 2

    Four measurement approaches for LACI include two-dimensional echocardiography, real-time three-dimensional echocardiography, speckle-tracking echocardiography, and AI-assisted analysis.

  • 3

    Two-dimensional echocardiography is optimal for screening, while real-time three-dimensional echocardiography provides the highest consistency with cardiovascular magnetic resonance.

  • 4

    Key limitations in LACI implementation include lack of cross-platform calibration, fragmented reference values, and absence of validated cutoffs.

  • 5

    Future efforts should focus on standardization, establishing reference values for specific populations, and conducting randomized controlled trials for LACI.
