Echocardiographic assessment of left ventricular (LV) diastolic function is an integral part of
the routine evaluation of patients presenting with symptoms of dyspnea or heart failure. The …

Left ventricular diastolic function plays an important role in determining left ventricular filling
and stroke volume. Abnormal diastolic function has been recognized in many cardiovascular …

The assessment of left ventricular (LV) diastolic function should be an integral part of a
routine examination, particularly in patients presenting with dyspnea or heart failure. About …

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 …

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 …

Objectives: The purpose of this study was to test the hypothesis that in heart failure with
normal ejection fraction (HFNEF) exercise limitation is due to combined systolic and diastolic …

Aims To examine myocardial deformation and rotation in patients with heart failure, and
elucidate the underlying mechanisms that account for normal ejection fraction (EF) in …

Aims Although the utility of two-dimensional (2D) speckle tracking echocardiography (STE)
to quantify left ventricular (LV) volume has been demonstrated, this methodology is limited …

The left ventricle twists in systole storing potential energy and untwists (recoils) in diastole
releasing the energy. Twist aids left ventricular ejection and untwist aids relaxation and …
