Global and regional myocardial function quantification by two-dimensional strain in Takotsubo cardiomyopathy.
AIMS This study sought to characterize global and regional systolic function in Takotsubo cardiomyopathy (TC) using two-dimensional (2D) strain imaging. METHODS AND RESULTS Twelve consecutive patients (11 women, 1 man) underwent 2D echocardiography on admission and on early follow-up (34 +/- 16 days). Two-dimensional images were analysed to measure longitudinal and radial strain and to calcul...
متن کاملQuantification of Regional Myocardial Function following Acute Myocardial Infarction by Ultrasonic Strain Rate and Strain Imaging
Objectives: The rapid diagnosis and early risk stratification of patients presenting with acute myocardial infarction (AMI) is important. In experimental setting ultrasonic strain rate (SR) and strain (S) have been shown to identify changes in deformation predictive of ischemia. We sought to evaluate and compare regional myocardial function at “the risk zone” (ARZ) supplied by the culprit coron...
متن کاملVolumetric quantification of global and regional left ventricular function from real-time three-dimensional echocardiographic images.
BACKGROUND Real-time 3D echocardiographic (RT3DE) data sets contain dynamic volumetric information on cardiac function. However, quantification of left ventricular (LV) function from 3D echocardiographic data is performed on cut-planes extracted from the 3D data sets and thus does not fully exploit the volumetric information. Accordingly, we developed a volumetric analysis technique aimed at qu...
متن کاملQuantitation of Regional Cardiac Function by Two-dimensional Echocardiography
Regional differences in wall motion and wall thickening were quantitated in the normal left ventricle using two-dimensional echocardiography (2-D echo). Using a computer-aided system, the left ventricle was subdivided in a standardized manner into 40 segments of five 2-D echo short-axis cross sections from the mitral valve level to the low left ventricle or apex. Measurements of sectional and s...
متن کاملMyocardial strain by Doppler echocardiography. Validation of a new method to quantify regional myocardial function.
BACKGROUND Myocardial strain is a measure of regional deformation, and by definition, negative strain means shortening and positive strain, elongation. This study investigates whether myocardial strain can be measured by Doppler echocardiography as the time integral of regional velocity gradients, using sonomicrometry as reference method. METHODS AND RESULTS In 13 anesthetized dogs, myocardia...
