    Left ventricular hypertrophy (LVH) alters aortic root motion, reducing the atrial emptying index (AEI). This echocardiographic finding offers a rapid method for assessing altered left ventricular filling in patients with LVH.

    Area of Science:

    • Cardiology
    • Echocardiography
    • Physiology

    Background:

    • Aortic root motion is linked to left atrial function.
    • Left ventricular hypertrophy (LVH) can affect diastolic filling patterns.

    Purpose of the Study:

    • To investigate if LVH alters posterior aortic root motion.
    • To assess the utility of the atrial emptying index (AEI) in identifying altered diastolic filling in LVH.

    Main Methods:

    • Echocardiograms of 60 patients with LVH (due to aortic stenosis, hypertrophic subaortic stenosis, hypertension) were compared to 36 normal subjects.
    • Analyzed posterior aortic root motion during diastole.
    • Calculated the atrial emptying index (AEI).

    Main Results:

    Related Experiment Videos

  • Patients with LVH showed attenuated, less abrupt diastolic posterior aortic root motion.
  • The AEI was significantly reduced in patients with LVH (p < 0.001).
  • AEI did not differentiate severity of hypertrophy.

    • Conclusions:

    • Altered posterior aortic root motion is characteristic of LVH.
    • The AEI is a valuable, visually assessed index for identifying altered left ventricular filling in LVH.
    • AEI provides a rapid qualitative assessment of diastolic function.
