OBJECTIVE Strain and strain rate imaging is currently the most popular echocardiographic technique that reveals subclinical myocardial damage. There are currently no available data on this imaging method with regard to assessing right ventricular involvement in anterior myocardial infarction. Therefore, we aimed to evaluate right ventricular regional functions using a derived strain and strain ...

OBJECTIVES This study sought to examine the changes in ventricular function of hypoplastic left heart syndrome (HLHS) between the first 2 stages of surgical palliation. BACKGROUND The mortality risk between first and second stages of surgical palliation in HLHS remains high. Right ventricular (RV) dysfunction predicts mortality. Postulated mechanisms include a maladaptive contraction pattern,...

BACKGROUND We describe a method for 3-/4D reconstruction of tissue Doppler data from three standard apical planes, post processing to derived data of strain rate/strain and parametric colour imaging of the data. The data can be displayed as M-mode arrays from all six walls, Bull's eye projection and a 3D surface figure that can be scrolled and rotated. Numerical data and waveforms can be re-ext...

conclusions echocardiography and 2d speckle tracking strain imaging shows improvements in left ventricular deformation indices in atrioventricular reentrant tachycardia (avrt) and atrioventricular nodal reentrant tachycardia (avnrt) patients for the mean systolic strain and strain rate at 24 hours and the three-month follow-up. in spite of the normal lvef, even during sinus rhythm, deformation ...

Cardiovascular magnetic resonance (MR) imaging can provide three-dimensional analysis of global and regional cardiac function with great accuracy and reproducibility. Quantitative assessment of regional function with cardiac MR imaging previously was limited by long acquisition times and time-consuming analysis. The use of steady-state free precession cine MR imaging substantially improves asse...

Imaging techniques have been widely implemented to study the dynamics of chip formation. They can offer a direct method and full field measurement cutting process, providing kinematic information formation process. In this article, state art imaging reported in literature has summarized analyzed. The applied mechanism, friction behavior, strain/strain rate, stress fields. Furthermore, surface i...
