Optimization of myocardial deformation imaging in term and preterm infants.
AIMS Myocardial deformation imaging is now used to assess regional ventricular function in infants but their small size presents particular technical challenges. We therefore investigated the determinants of reproducibility of myocardial longitudinal strain (ε) in term and preterm infants, in order to determine optimal technical settings. METHODS AND RESULTS Repeated longitudinal ε measuremen...
متن کاملVelocity and deformation imaging for the assessment of myocardial dysfunction.
Recent developments in echocardiographic imaging technology and processing enabled the quantification of myocardial motion and deformation in a clinical setting. Echocardiographic strain (-rate) imaging provides a relatively easy way to study myocardial deformation. However, although (local) deformation is clearly linked to cardiac (dys-) function, it is important to understand how this informa...
متن کاملImpact of infarct transmurality on layer-specific impairment of myocardial function: a myocardial deformation imaging study.
AIMS To evaluate deformation parameters of an endocardial, mid-myocardial, and epicardial myocardial layer in different transmurality of myocardial infarction and assess whether layer-specific deformation analysis allows definition of infarct transmurality. METHODS AND RESULTS Fifty-six patients (mean age 55 +/- 9 years, 38 men) with chronic ischaemic left ventricular (LV) dysfunction underwe...
متن کاملTranslation of Methdology used in Human Myocardial Imaging to a Sheep Model of Acute Myocardial Infarction
Background: Pre-clinical investigation of stem cells for repairing damaged myocardium predominantly used rodents, however large animals have cardiac circulation closely resembling the human heart. The aim of this study was to evaluate whether SPECT/CT myocardial perfusion imaging (MPI) could be used for assessing sheep myocardium following an acute myocardial infarction (MI) and response to int...
متن کاملmyocardial deformation indices in patients with significant aortic regurgitation: a strain rate imaging study
conclusions our results demonstrated the ability of pw-tdi and s/sr modalities in detection of the early subclinical abnormalities in asymptomatic patients with significant chronic ar. results ar group had significantly increased lv end systolic and end diastolic volumes, interventricular septum and posterior wall thickness compared to controls. in ar, sm and em of septal wall, sm of lateral wa...
