Speckle tracking echocardiography in acute myocarditis

The International Journal of Cardiovascular Imaging, 2012
To evaluate 2-dimensional speckle tracking echocardiography as a diagnostic and prognostic tool in patients with acute myocarditis. In this retrospective cohort study, 45 patients (age, 39 ± 15 years; 32 male) with suspected acute myocarditis and 83 healthy controls (age, 39 ± 13 years; 27 male) underwent 2-dimensional speckle tracking echocardiography.

[Speckle tracking echocardiography: a practical guide].

Giornale italiano di cardiologia (2006), 2017
Speckle tracking echocardiography (STE) has recently emerged as a quantitative technique to accurately estimate myocardial function. By the analysis of the motion of speckles in the two-dimensional ultrasonic image, this technique allows a non-Doppler angle-independent objective analysis of myocardial deformation, with the possibility to quantify ...

Speckle Tracking in 3D Echocardiography with Motion Coherence

2007 IEEE Conference on Computer Vision and Pattern Recognition, 2007
Tracking of speckles in echocardiography enables the study of myocardium deformation, and thus can provide insights about heart structure and function. Most of the current methods are based on 2D speckle tracking, which suffers from errors due to through-plane decorrelation. Speckle tracking in 3D overcomes such limitation. However, 3D speckle tracking

Speckle-tracking echocardiography: state of art and its applications

Minerva Medica, 2023
Echocardiographic evaluation of left ventricular ejection fraction (LVEF) provides important information regarding both myocardial function and prognosis. This parameter presents various limitations and does not allow early detection of myocardial dysfunction. LVEF may be related to hemodynamic load, geometric assumptions, to image quality, and it does

Use of Three-Dimensional Speckle-Tracking Echocardiography for Quantitative Assessment of Global Left Ventricular Function: A Comparative Study to Three-Dimensional Echocardiography

Journal of the American Society of Echocardiography, 2014
BACKGROUND: The aim of this study was to determine whether global strains derived from three-dimensional (3D) speckle-tracking echocardiography (STE) are as accurate as left ventricular (LV) ejection fraction (LVEF) obtained by two-dimensional (2D) and ...

Atrial Myopathy Quantified by Speckle-tracking Echocardiography in Mice

Circulation: Cardiovascular Imaging, 2023
BACKGROUND: Emerging evidence suggests that atrial myopathy may be the underlying pathophysiology that explains adverse cardiovascular outcomes in heart failure (HF) and atrial fibrillation. Lower left atrial (LA) function (strain) is a key biomarker of atrial myopathy, but murine LA strain has not been described, thus limiting

New developments in speckle tracking echocardiography

Choonpa Igaku, 2010
スペックルトラッキング法は，組織ドプラ法と違って，運動方向にとらわれずに心筋の速度を知ることが出来る．したがって，心筋の動線に沿ったストレインやストレインレートを壁の部位によらず求めることが出来る．このことはdyssynchronyの評価や虚血のサインであるpostsystolic shorteningの評価に有利である．また，最近は心筋全層の機能のみならず，心筋内スペックルを追跡することにより心内膜下層，中層，心外膜下層の機能も評価出来るようになってきた．心筋層別の機能評価が出来るようになれば，心筋虚血など種々疾患の詳細な評価が可能であり，新しい病態解析に繋がるであろう．さらに ...

Detection of left atrial dysfunction with speckle tracking echocardiography

Herz, 2016
The aim of this study was to evaluate the relationship between the SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) score and left ventricular end-diastolic pressure (LVEDP) measured with an invasive method and with speckle-tracking echocardiography (STE).The study included 124 patients who underwent cardiac catheterization. LVEDP values and

Speckle Tracking Echocardiography in Pediatric and Congenital Heart Disease

Echocardiography, 2013
Assessment of myocardial strain using speckle tracking echocardiography is an emerging echocardiographic technique that is increasingly used in the diagnosis and management of acquired heart disease in adults. In pediatric heart disease, this is still mainly considered as a research tool as the application of this technology has been slowed by the lack

Three Dimensional Speckle Tracking Echocardiography in Hemodialysis Patients

Hemodialysis International
ABSTRACT Background It has been suggested that ventricular strain measurements may be impaired in chronic hemodialysis patients despite having no history of heart disease. The aim of this study is to investigate whether ventricular strain parameters can be used to detect subclinical cardiac ...
