The authors summarize the recent developments in speckle-tracking echocardiography
(STE), a relatively new technique that can be used in conjunction with two-dimensional or …

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 …

Recently there has been considerable interest in LV torsion and its relationship with
symptomatic and pre-symptomatic disease processes. Torsion gives useful additional …

Speckle tracking echocardiography (STE) is an emerging tool to characterize and quantify
myocardial segmental and rotational mechanics. This literature review is aimed at clinical …

Aims Decreased left ventricular (LV) rotation and torsion and even reversed systolic apical
rotation have been described in patients with dilated cardiomyopathy (DCM). We sought to …

Background To determine the inter‐study reproducibility of MR feature tracking (MR‐FT)
derived left ventricular (LV) torsion and torsion rates for a combined assessment of systolic …

Left ventricular mechanical dyssynchrony (LVMD) is defined by a difference in the timing of
mechanical contraction or relaxation between different segments of the left ventricle (LV) …

Key points• Left ventricular twist (LVT) results from rotation of the LV apex and base in
opposite directions.• Although LVT is altered in various cardiac diseases, physiological …

A number of echocardiographic techniques have been introduced to determine left
ventricular dyssynchrony (LVD) and to improve selection of patients for CRT. During the last …

Normal cardiac function of the left and right ventricles, together with the septum, is related to
form/function interactions within the helical ventricular myocardial band. This knowledge is a …
