Speckled myocardium echo
WebJun 26, 2024 · Strain is an advanced echocardiographic technique that assesses myocardial function by evaluating deformation of the myocardium. It is reported as a dimensionless percentage of myocardial deformation and may be determined using tissue Doppler imaging or speckle-tracking echocardiography. Tissue Doppler imaging, an earlier technique, was … WebSpeckle tracking echocardiography permits assessment of myocardial strain in three spatial directions (longitudinal, radial and circumferential) independent of the angle of insonation of the ultrasound beam. Longitudinal strain is probably the most frequent type of strain used to characterise LV systolic function in clinical practice.

WebNational Center for Biotechnology Information WebMovement of the echo-reflecting speckle patterns in the myocardium is utilized to image the shortening of every segment during various phases of the cardiac cycle. Within each region of interest in the myocardium, the image-processing algorithm automatically subdivides regions into blocks of pixels tracking stable patterns of speckles.
WebCardiac amyloidosis may even coexist with aortic stenosis 1 and other patients with new-onset atrial fibrillation. 2 In this editorial, we discuss the role of left ventricular speckle … WebThe high sensitivity of both tissue Doppler imaging (TDI) derived and two dimensional (2D) speckle tracking derived myocardial deformation (strain and strain rate) data for the early detection of myocardial dysfunction recommend these new non-invasive diagnostic methods for extensive clinical use.
WebHypertrophic cardiomyopathy is a genetic disorder that causes left ventricular hypertrophy under normal loading conditions. Hypertrophic cardiomyopathy should not be confused with hypertrophy caused by increased loading conditions. Increased ventricular load is mostly caused by systemic hypertension or aortic stenosis. WebFeb 23, 2024 · Strain is a unitless measurement of dimensional or deformational change; speckle-tracking echocardiography is the most widely used technique to assess strain, with demonstrated clinical utility in a variety of settings. This paper reviews the diagnostic and prognostic impact of echocardiographic assessment of myocardial strain.
WebJul 12, 2024 · Background: The influence of age and gender on strain-imaging-derived myocardial work (MW) was recently investigated in healthy subjects. No information is available on the impact of heart rate (HR) on MW. Methods: 177 healthy subjects (47% men, mean age 42 years) underwent an echo-Doppler exam, including quantification of global …
