Speckle‐tracking echocardiography has recently emerged as a quantitative ultrasound
technique for accurately evaluating myocardial function by analyzing the motion of speckles …

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 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 …

Blood motion in the heart features vortices that accompany the redirection of jet flows
towards the outlet tracks. Vortices have a crucial role in fluid dynamics. The stability of …

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

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 …

Objectives: The aims of this study were to: 1) assess the feasibility of left ventricular (LV)
vortex flow analysis using contrast echocardiography (CE); and 2) characterize and quantify …

It has now been a quarter of a century since the first description by Kitabatake and his
associates of the use of echo-Doppler to characterize the transmitral flow velocity curves in …

Blood flow patterns are closely linked to the morphology and function of the cardiovascular
system. These patterns reflect the exceptional adaptability of the cardiovascular system to …

Whole-field velocity measurement techniques based on ultrasound imaging (aka 'ultrasound
imaging velocimetry'or 'echo-PIV') have received significant attention from the fluid …
