clinical application of left ventricular twist: a twist in the right direction?

Left Ventricular Twist in Cardiomyopathy

Left ventricular twist and torsion: research observations and clinical applications.

Left ventricular twist in a normal African adult population.

AIMS Speckle tracking has emerged as a quantitative technique for assessing left ventricular (LV) function. However, no normative data for LV twist using speckle tracking echocardiography (STE) are available in the black population. This study assessed myocardial mechanics by determining LV twist parameters in different age groups using STE, and evaluated the effect of ageing on LV twist in thi...

Left ventricular twist abnormalities in patients with left ventricular non-compaction. A cardiovascular magnetic resonance study

Background Current morphologic left ventricular (LV) non-compaction (LVNC) criteria seem to be still insufficient. The prevalence of borderline degree of LV hypertrabeculation is far more frequent than initially expected. LV twist and strain values are proposed as potential new functional parameters supplementing the classic morphologic LVNC criteria. The aim of this study was to assess diagnos...

Simulation of a New Process Design to Fabricate a Rectangular Twist Waveguide Using Extrusion and a Twist Die

The aim of the present study is to determine the feasibility of making a rectangular twist waveguide used to rotate electromagnetic waves. For this purpose, the process of fabricating an aluminum rectangular twist waveguide was simulated by making use of finite element method and Deform software. The optimum length and angle of the twist die for manufacturing a twist waveguide with inner cross ...

Influence of cardiac shape on left ventricular twist.

The dynamic interaction between subendocardial and subepicardial fibre helices in the left ventricle (LV) leads to a twisting deformation, which has an important role in LV function. This study sought to assess the influence of cardiac shape on LV twist in the normal and dilated human heart. The study comprised 45 dilated cardiomyopathy (DCM) patients and 60 for age- and gender-matched healthy ...
