Abstract Three-dimensional (3D) speckle-tracking echocardiography (3DSTE) is an
advanced imaging technique designed for left ventricular (LV) myocardial deformation …

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 …

Background—Left ventricular (LV) torsion is due to oppositely directed apical and basal
rotation and has been proposed as a sensitive marker of LV function. In the present study …

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 …

The keynote to understanding cardiac function is recognizing the underlying architecture
responsible for the contractile mechanisms that produce the narrowing, shortening …

Brief Communications segment (light gray). The fibers of ascending and descending
segments cross each other at a 90 angle at the level of the septum. Following such a plane …

Cardiovascular magnetic resonance (CMR) tagging has been established as an essential
technique for measuring regional myocardial function. It allows quantification of local …

Rapid progress has been made in cardiac MRI (CMRI) over the past decade, which has
firmly established it as a reliable and clinically important technique for assessment of cardiac …

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 …

During left ventricular (LV) torsion, the base rotates in an overall clockwise direction and the
apex rotates in a counterclockwise direction when viewed from apex to base. LV torsion is …
