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 …

Background The clinical applicability and reliability of three-dimensional (3D) speckle-
tracking echocardiography has not been well studied in pediatric patients. The aim of this …

Background and Objectives This study was aimed at assessing left ventricular torsion (LVtor)
mechanics using speckle tracking echocardiography (STE), establishing normal reference …

Background: During the physiological cardiac cycle, the helix orientation of the muscle fibres
induces the rotation of the apex relative to the base of the left ventricular (LV). In heart …

Introduction: Left ventricular (LV) strains are measures of deformation that reflect LV function
quantifying the rate of LV contraction, providing information in three directions in space …

Background Global systolic left ventricular (LV) myocardial function progressively declines
as degenerative aortic valve stenosis (AS) progresses. Whether this results in uniformly …

Background: The left ventricular (LV) rotational mechanics are of particular importance in the
function of the LV. The rotational movement is the consequence of the arrangement of the …

Abstract Traditional two-dimensional (2D) ultrasound speckle tracking echocardiography
(STE) studies have shown a wide range of twist values, also for normal hearts, which is due …

Left ventricular (LV) twist mechanics are routinely assessed via echocardiography in clinical
and research trials investigating the function of obliquely oriented myocardial fibers …

Background Recent advances had allowed measurement of myocardial deformation
parameters using 3D speckle‐tracking echocardiography (STE). Agreement between these …
