Myocardial tissue tracking imaging techniques have been developed for a more accurate
evaluation of myocardial deformation (ie strain), with the potential to overcome the …

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 interest in the left atrium (LA) has resurged over the recent years. In the early 1980s,
multiple studies were conducted to determine the normal values of LA size. Over the past …

Background: To determine the normal range of left ventricular (LV) 2-dimensional (2-D)
strain and vendor-specific differences, a multicenter prospective 2-D strain study endorsed …

Background—Mechanical dyssynchrony is a potential means to predict response to cardiac
resynchronization therapy (CRT). We hypothesized that novel echocardiographic image …

Background The role of speckle tracking in the assessment of left atrial (LA) deformation
dynamics is not established. We sought to determine the feasibility and reference ranges of …

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 …

Objectives: We sought to investigate the clinical prognostic value of longitudinal and
circumferential strain (S) and strain rate (SR) in patients after high-risk myocardial infarction …

BACKGROUND: Increased left atrial (LA) size and reduced global contractility are related to
adverse cardiac events. The potential incremental value of assessing regional LA …

Background—Diastolic strain rate (SR) measurements that comprise all left ventricular (LV)
segments are advantageous over myocardial velocity for assessment of diastolic function …
