Speckle tracking echocardiography in cardiac amyloidosis
Heart Failure Reviews, 2019Speckle tracking echocardiography is an imaging method, based on analysis of 2D echocardiographic images, that is useful in providing information on tissue deformation in different cardiac diseases. Cardiac amyloidosis is a complex pathological entity that can be confused with other causes responsible for cardiac hypertrophy, and for this reason, it ...

A new era: Speckle tracking echocardiography and cardiomyopathies
Journal of Clinical Ultrasound, 2022AbstractLimb‐girdle muscular dystrophy (LGMD) is a heterogeneous inherited disorder affecting the skeletal muscle and frequently also involve the heart and in LGMD; development of dilated cardiomyopathy is common and usually the predominant feature. Arrhythmias and conduction disease can be associated with the development of cardiomyopathy.

[Speckle tracking echocardiography: a practical guide].
Giornale italiano di cardiologia (2006), 2017Speckle 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 ...

Two dimensional speckle tracking echocardiography: clinical applications
Heart, 2010This review is the second of two articles that focus on two dimensional speckle tracking echocardiography (STE). While the first article described the principles of STE, this review deals with its potential clinical applications. The technology of speckle tracking based strain analysis is rather new.w1 w2 However, there is considerable experience with ...

Speckle tracking echocardiography: principles and clinical applications
Journal of Medicine and Pharmacy, 2023Speckle Tracking Echocardiography is a relatively new, non-invasive ultrasound technique that allows an objective and quantitative evaluation of global and regional myocardial function. There is a lot of evidence that global longitudinal strain is more sensitive than the left ventricular ejection fraction for the assessment of left ventricular ...

Speckle tracking echocardiography: imaging insights into the aorta
Current Opinion in Cardiology, 2020Purpose of review Pathophysiologic changes of aortic tissue may not always manifest as aneurysms, nor does the size of an aneurysm necessarily represent the severity of tissue abnormality – approximately 40% of patients who present with dissection have aortic diameters below criteria recommended for surgical resection ...

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 ...

Near-Field Clutter Mitigation in Speckle Tracking Echocardiography
Ultrasound in Medicine & BiologyNear-field (NF) clutter filters are critical for unveiling true myocardial structure and dynamics. Randomized singular value decomposition (rSVD) stands out for its proven computational efficiency and robustness. This study investigates the effect of rSVD-based NF clutter filtering on myocardial motion estimation.In silico, material points and their ...

Speckle Tracking Imaging in Normal Stress Echocardiography.
Journal of ultrasound in medicine : official journal of the American Institute of Ultrasound in Medicine, 2017Exercise stress echocardiography is a widely used modality for the diagnosis and follow-up of patients with coronary artery disease. During the last decade, speckle tracking imaging has been used increasingly for accurate evaluation of cardiac function.
