“…In 2DSTE and 3DSTE studies, there is an agreement that regardless of gender, LV rotational and twist parameters increase with aging. 19,20,22,23 Notomi et al 24 reported that in infancy the LV basal rotation is counterclockwise and it gradually shifts over to clockwise rotation using TDI; in contrast to this finding, Kaku et al 23 found that in infancy the LV basal rotation is clockwise rotation using 3DSTE.…”

Introduction Left ventricular (LV) rotation and twist are essential parts of LV function. Three‐dimensional speckle tracking echocardiography (3DSTE) is a relatively new method and is useful for the quantification of LV wall deformation and rotational parameters. The aim of the present study was to examine LV rotation and twist differences between different age‐groups and genders in a healthy population. Methods The present study is comprised of 297 healthy adults; 120 adults have been excluded due to inferior image quality. The population was further divided into 4 subgroups based on age decades. Results Only the LV twist of all patients (13.5 ± 3.7 degree vs 15.6 ± 4.9 degree, P = 0.02) and the LV twist of females (13.0 ± 3.6 degree vs 15.5 ± 5.6 degree, P = 0.03) differed significantly between the age‐group of 18–29 years and 50+ years. LV basal and apical rotation were not significantly different between the age‐groups; however, they tendentiously increased with aging. No significant differences could be demonstrated regarding LV rotational and twist parameters between genders in any group. A phenomenon called LV rigid body rotation (LV‐RBR)—where the base and apex of the LV rotate in the same direction—was present in 10 cases. Conclusions Three‐dimensional speckle tracking echocardiography seems to be a reasonably viable tool for the quantification of LV rotation and twist. Both LV basal and apical rotation and LV twist increase with aging, regardless of gender. LV‐RBR is also present in the normal population.

“…LV untwisting begins in late systole in normal hearts and continues throughout the isovolumic relaxation period, preceding inflow across the mitral valve. LV untwisting is an important mechanism that aids LV filling at a normal LA pressure . Therefore, LV diastolic function depends largely on the degree and rate of LV untwisting.…”

“…In the presented case with calpainopathy, routine echocardiographic examination did not confirm systolic or diastolic heart failure. However, over reduced LV strains, significantly increased LV apical rotation and LV twist were found indicating asymptomatic subclinical (latent) LV dysfunction (26)(27)(28)(29).…”

Assessment of Age‐Related Changes in Left Ventricular Twist by 3‐Dimensional Speckle‐Tracking Echocardiography

Abstract: Three-dimensional speckle-tracking echocardiography can be an effective noninvasive method for assessing 3D LV twist. Age-related differences in the 3D LV twist may be the result of the age-related changes in the endocardial myofibers.
