Left ventricular (LV) twist or torsion represents the mean longitudinal gradient of the net
difference in clockwise and counterclockwise rotation of the LV apex and base, as viewed …

The cells and tissues that make up our body manage contradictory mechanical demands. It
is crucial for their survival to be able to withstand large mechanical loads, but it is equally …

The myofiber geometry of the left ventricle (LV) changes gradually from a right-handed helix
in the subendocardium to a left-handed helix in the subepicardium. In this review, we …

Gyrocardiography (GCG) is a new non-invasive technique for assessing heart motions by
using a sensor of angular motion–gyroscope–attached to the skin of the chest. In this study …

Doppler tissue imaging (DTI) and DTI-derived strain imaging are robust physiologic tools
used for the noninvasive assessment of regional myocardial function. As a result of high …

Soft biological tissues often undergo large (nearly) elastic deformations that can be
analyzed using the nonlinear theory of elasticity. Because of the varied approaches to …

Cardiac dynamics are traditionally linked to a left ventricle, right ventricle, and septum
morphology, a topography that differs from the heart's five-century-old anatomic description …

Structural remodeling of myocardium after infarction plays a critical role in functional
adaptation. Diffusion tensor magnetic resonance imaging (DTMRI) provides a means for …

Background—Left ventricular (LV) torsional deformation, based in part on the helical
myocardial fiber architecture, is an important component of LV systolic and diastolic …

Dynamic changes of myocardial fiber and sheet structure are key determinants of regional
ventricular function. However, quantitative characterization of the contraction-related …
