Two-Dimensional Speckle-Tracking Echocardiography in Normal Korean Population: Is Now to Start Using in Routine Clinical Practice?
Left ventricle (LV) strain measurement by using the two-dimensional (2D) speckle-tracking echocardiography (STE) was first described in 2004, 1) and has been widely applied in research , and the number of publications in the medical literature regarding the clinical utility of STE has been grown rapidly. 2)3) STE is based on frame-by-frame image tracking of tiny natural acoustic markers within ...
متن کاملSpeckle tracking for multi-dimensional flow estimation.
Speckle tracking methods overcome the major limitations of current Doppler methods for flow imaging and quantification: angle dependence and aliasing. In this paper, we review the development of speckle tracking, with particular attention to the advantages and limitations of two-dimensional algorithms that use a single transducer aperture. Ensemble tracking, a recent speckle tracking method bas...
متن کاملAccuracy of Two-Dimensional Speckle Tracking Echocardiography for the Detection of Significant Coronary Stenosis
BACKGROUND Visual assessment of wall motion abnormalities (WMA) by 2-dimensional echocardiography (2DE) is the most semi-quantitative method used to detect coronary artery disease (CAD), but it carries many limitations. Speckle tracking echocardiography (STE) overcomes these limitations and allows an objective quantification of myocardial deformation. The aim of the study to examine the accurac...
متن کاملTwo-dimensional speckle-tracking echocardiography for evaluation of dilative ascending aorta biomechanics
BACKGROUND Two-dimensional (2D) echocardiography is one of the most feasible, noninvasive methods for assessing the aortic diameter and biomechanical changes. We studied possible interfaces between noninvasive biomechanical and speckle-tracking (ST) echocardiographic data from dilated aortas. METHODS Altogether, 44 patients with dilative pathology of ascending aorta (DPAA) were compared with ...
متن کاملEvaluation of myocardial mechanics with three-dimensional speckle tracking echocardiography in heart transplant recipients: comparison with two-dimensional speckle tracking and relationship with clinical variables.
AIMS Two-dimensional speckle-tracking echocardiography (2D-STE) is limited by its inability to track tissue motion in three dimensions. This is particularly relevant in heart transplant recipients, in whom marked translational motion of the transplanted heart is present. We aimed to compare 3-dimensional (3D)- and 2D-STE-derived strain parameters, and to identify clinical features associated wi...
