BACKGROUND Evaluation of myocardial function by speckle-tracking echocardiography is a new method for the early diagnosis of systolic dysfunction. OBJECTIVES We aimed to determine myocardial speckle-tracking echocardiography indices in Kawasaki Disease (KD) patients and compare them with the same indices in control subjects. PATIENTS AND METHODS Thirty-two patients (65.5% males) with KD and...

This paper proposes a robust real-time myocardial border tracking algorithm for echocardiography. Commonly, after an initial contour of LV border is traced at one or two frames from the entire cardiac cycle, LV contour tracking is performed over the remaining frames. Among a variety of tracking techniques, optical flow method is the most widely used for motion estimation of moving objects. Howe...

Background Global longitudinal strain (GLS), has shown utility in detecting early subclinical LV dysfunction and has demonstrated significant efficacy in evaluating patients for chemotherapy cardiotoxicity. However, echocardiography is often reliant on operator experience and adequate quality windows for assessment. CMR is not subject to limitations of poor image quality due to its superior end...

The feasibility and potential for the morphological and hemodynamic investigation of the heart has been increasing the use of the echocardiography in the research setting. Additionally, the development of new technologies, like the real time 3D echocardiography and speckle tracking, demands validation throughout experimental studies before being instituted in the clinical setting. This paper ai...

Abstract Introduction The left atrium (LA)’s essential function is modulating ventricular (LV) filling via its different reservoir, conduit, and contractile functions. This could be accurately achieved now by dedicated speckle-tracking echocardiography software. Methodology We included in this prospective cohort study 200 subjects with structurally normal hearts, who present for elective echoca...

Recognizing the critical need for standardization in strain imaging, in 2010, the European Association of Echocardiography (now the European Association of Cardiovascular Imaging, EACVI) and the American Society of Echocardiography (ASE) invited technical representatives from all interested vendors to participate in a concerted effort to reduce intervendor variability of strain measurement. As ...

conclusions echocardiography and 2d speckle tracking strain imaging shows improvements in left ventricular deformation indices in atrioventricular reentrant tachycardia (avrt) and atrioventricular nodal reentrant tachycardia (avnrt) patients for the mean systolic strain and strain rate at 24 hours and the three-month follow-up. in spite of the normal lvef, even during sinus rhythm, deformation ...

Echocardiography is the most common diagnostic tool for patients with heart disease, providing detailed information about cardiovascular morphology and hemodynamics previously available only by angiography and catheterization. It is noninvasive, widely available and inexpensive. With its huge evidence base, echocardiography has a central position in modern cardiac diagnosis and management. Rece...

AIMS Speckle tracking echocardiography has already demonstrated its clinical potential. However, its use in routine practice is jeopardized by recent reports on high inter-vendor variability of the measurements. As such, the European Association of CardioVascular Imaging (EACVI) and the American Society of Echocardiography (ASE) set up a standardization task force, which was joined by all manuf...

Left ventricular (LV) function is normally improved after renal transplant; however, cardiovascular mortality remains elevated. Moderate physical activity has a positive impact on myocardial function; however, few data are available about the role of 2D echocardiography (2DE) and 2D speckle tracking echocardiography (2DSTE) on renal transplant recipients (RTR). From a large cohort of RTR submit...
