The concept of ultrafast echocardiographic imaging has been around for decades. However, only recent progress in ultrasound machine hardware and computer technology allowed to apply this echocardiography. High frame rate echocardiography can visualize phenomena that have never captured before. It enables a wide variety potential new applications, including shear wave imaging, speckle tracking, ...

UNLABELLED SummaryWe present the case of a 26-year-old male with acute tonsillitis who was referred for coronary angiography because of chest pain, elevated cardiac biomarkers, and biphasic T waves. The patient had no cardiovascular risk factors. Echocardiography showed no wall motion abnormalities and no pericardial effusion. 2D speckle tracking revealed distinct decreased regional peak longit...

Three-dimensional (3-D) speckle tracking echocardiography allows us to track a change in regional endocardial surface area. The change of regional area during a cardiac cycle should be useful for assessing left ventricular regional work. We investigated the feasibility of assessing regional work, calculated as the area within the wall tension-regional area (T-A) loop using 3-D 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 ...

Myocardial contrast echocardiography (MCE) and two-dimensional speckle tracking (2D-STE) were used to detect left ventricular myocardial microcirculation perfusion systolic function in dilated cardiomyopathy (DCM) explore the relationship between two.

3D+T echocardiography is a valuable tool for assessing cardiac function, as it enables real-time, non-invasive and low cost acquisition of volumetric images of the heart. The automated tracking of heart chambers in 3D+T echocardiography remains a challenging task due to reasons including speckle noise, shadowing, and the existence of intra-cavity structures [6]. Furthermore, the real-time detec...

BACKGROUND To examine the subclinical myocardial injury shortly after epirubicin exposure in asymptomatic patients with large B-cell non-Hodgkin lymphoma using 2-dimensional (2D) speckle tracking echocardiography. METHODS Sixty-seven patients aged 52.58 ± 13.86 years with large B-cell non-Hodgkin lymphoma treated with epirubicin were studied. Echocardiography was performed at baseline and 1 d...

Speckle -tracking echocardiography (STE) provides quantitative information about myocardial deformation, more accurately than conven...

OBJECTIVES This study assessed the use of 3-dimensional (3D) speckle-tracking echocardiography for noninvasive monitoring and diagnosis of acute rejection in heart transplant recipients. METHODS Fifteen heart transplant recipients underwent 32 endomyocardial biopsies; echocardiography was performed within 3 hours before biopsy. Twenty-four biopsies (acute rejection-negative group) showed grad...

background: the recent developments in tissue doppler imaging (tdi) now more than ever permit the quantification of the myocardial function. in the current systems, tissue tracking or displacement curves are generated from color tissue doppler data through the instantaneous temporal integral of velocity-time curves. methods: the purpose of the present study was to assess regional myocardial dis...
