OBJECTIVE Cardiac failure due to iron overload remains the most common cause of death in patients with beta-thalassemia major. This study aimed to evaluate myocardial function in children with beta-thalassemia major using standard echocardiography technique and strain rate imaging. MATERIALS AND METHODS Conventional echocardiographic analysis, tissue velocity imaging, and strain/strain rate i...

Meeting abstracts Aims Type-1 diabetes mellitus (T1DM) is among the most common chronic diseases in children. Serious long-term complications include both ultra-morphologic and functional cardiac impairment. Whether these pathologic proce...

OBJECTIVE In patients with aortic stenosis (AS), the left ventricular (LV) geometry changes due to the increased LV afterload. However, subclinical myocardial dysfunction can develop despite a normal LV ejection fraction (EF). This study was an investigation of subclinical LV systolic dysfunction in patients with severe AS with a normal LV EF using a strain imaging method, speckle-tracking echo...

conclusions despite the widespread use of 2d lvef and its good agreement with ventriculography, strain analysis seems to be more reliable as a quantitative tool for ventricular assessment. results the lvef values obtained by the two methods of ventriculography and echocardiography were not significantly different. the highest correlation regarding the echocardiographic lvef was obtained in the ...

AIMS The present study aims to compare the change of left ventricular deformation during dobutamine stress echocardiography (DSE) with the reference standard of invasive myocardial fractional flow reserve (FFR) to assess the haemodynamic significance of intermediate coronary lesions. METHODS AND RESULTS In 30 patients with an intermediate coronary artery stenosis in one epicardial coronary ar...

BACKGROUND The utility of longitudinal, circumferential, and radial strain and strain rate in determining prognosis in chronic heart failure is not well established. METHODS AND RESULTS In 416 patients with chronic systolic heart failure, we performed speckle-tracking analyses of left ventricular longitudinal, circumferential, and radial strain and strain rate on archived echocardiography ima...
