BACKGROUND Amyloidosis is a disease caused by deposits of insoluble fibrils in extracellular spaces. The most common type of familial amyloidosis is mediated by mutation of transthyretin, especially Val30Met. Symptoms and ejection fraction decrease may occur in cardiac amyloidosis only in case of poor prognosis. Myocardial strain detected by two-dimensional speckle tracking echocardiography can...

OBJECTIVES The aim of this study was to test myocardial deformation imaging using speckle-tracking echocardiography for predicting outcomes in chronic aortic regurgitation. BACKGROUND In chronic aortic regurgitation, left ventricular (LV) dysfunction must be detected early to allow timely surgery. Speckle-tracking echocardiography has been proposed for this purpose, but the clinical value of ...

background two-dimensional (2d) strain is a new reproducible technique for assessing regional myocardial function; however, its application for evaluation of left atrium (la) function is less studied. objectives we sought to assess la function in heart failure patients using velocity vector imaging (vvi). patients and methods thirty five patients (mean age: 43.34 ± 18.1 years, 59.3% male) with ...

Speckle Tracking Echocardiography is a relatively new, non-invasive ultrasound technique that allows an objective and quantitative evaluation of global regional myocardial function. There lot evidence longitudinal strain more sensitive than the left ventricular ejection fraction for assessment dysfunction, used to follow-up cancer therapeutic-related cardiac stratify risks, classify determine t...

background: echocardiographic evaluations of the longitudinal axis of the left ventricular (lv) function have been used in the diagnosis and assessment of heart failure with normal ejection fraction (hfnef). the evaluation of the global and segmental peak systolic longitudinal strains (pslss) by two-dimensional speckle tracking echocardiography (ste) may correlate with conventional echocardiogr...

AIMS The aims of this study were (1) to evaluate the relationship between novel two-dimensional transthoracic indices of left atrial (LA) mechanical function (speckle-tracking- and tissue Doppler-derived parameters), conventional indices (A-wave peak velocity and velocity-time integral, and A' velocity), and transoesophageal echocardiographic parameters (LA appendage emptying velocity and spont...

To evaluate the frequency and clinical features of heart involvement in Fabry disease (FD) diagnostic value cardiac MRI speckle-tracking echocardiography.

It is well known that arterial function relates to cardiovascular morbidity and mortality. The noninvasive technology for the assessment of arterial function has developed as the importance of prevention of early cardiovascular disease has been emphasized. Over 2-D and Doppler echocardiography, speckle-tracking echocardiography has emerged as a valuable ultrasound imaging technique that allows ...
