relation between parameters of myocardial mechanics and ventricular arterial coupling: a three-dimensional speckle-tracking study in healthy adults
objectives our aim was to study the relation between vac and the parameters of myocardial mechanics using three-dimensional speckle-tracking echocardiography (3dste). patients and methods we studied 68 normal participants (mean age, 35 ± 12.2 y; 36 [53%] males). vac was measured by the ratio of arterial elastance (ea) to ventricular elastance (ees). the peak systolic value of longitudinal strai...
متن کاملAge-Related Changes in Left Ventricular Torsion as Assessed by 2-Dimensional Ultrasound Speckle Tracking Imaging
Background and Objectives: The newly developed 2-dimensional ultrasound speckle tracking imaging (2D-STI) has enabled researchers to assess the changes of left ventricular (LV) rotation and torsion. The aims of the present study are to establish normal values and to examine the effect of advancing age on left ventricular torsion. Subjects and Methods: We enrolled 182 healthy persons in this stu...
متن کاملAge- and gender-related normal left ventricular deformation assessed by cardiovascular magnetic resonance feature tracking
BACKGROUND Assessment of left (LV) ventricular function is one of the most important tasks of cardiovascular magnetic resonance (CMR). Impairment of LV deformation is a strong predictor of cardiovascular outcome in various cardiac diseases like ischemic heart disease or cardiomyopathies. The aim of the study was to provide reference values for myocardial deformation derived from the CMR feature...
متن کاملleft ventricular function after arterial switch operation as assessed by two-dimensional speckle-tracking echocardiography in patients with simple transposition of the great arteries
background: the late postoperative course for children with transposition of the great arteries (tga) with an intact ventricular septum (ivs) is very important because the coronary arteries may be at risk of damage during arterial switch operation (aso). we sought to investigate left ventricular function in patients with tga/ivs by echocardiography. methods: from march 2011 to december 2012, t...

by 2D-STE, and investigated the effect of cardiovascular risk factors on LA-LV-arterial coupling.1 In their multivariate linear regression analysis, peak early diastolic LV longitudinal strain rate (SR-LVe) and E/e’/S-LAs were independent predictors related to abdominal aortic stiffness in patients with cardiovascular risk factors. On the other hand, only age contributed to abdominal aortic sti...
