in order to identify left ventricular diastolic function in patients with betathalassemia major and normal systolic function by noninvasive m-mode and doppler echocardiography, an analytic study was designed in a university hospital in sari. we have studied 44 patients (23 men and 21 women), mean age 15.48±2.16 (range 12 to 20) and 43 age and sex matched control subjects. peak flow velocity in ...

BACKGROUND Contemporary understanding of exercise-induced cardiac remodeling is based on cross-sectional data and relatively short duration longitudinal studies. Temporal progression of exercise-induced cardiac remodeling remains incompletely understood. METHODS AND RESULTS A longitudinal repeated-measures study design using 2-dimensional and speckle-tracking echocardiography was used to exam...

abstract background prevention of myocardial siderosis is a key step to reduce rate of mortality in thalassemic patients. our objective was to study association between echocardiography parameters and serum ferritin level in patients with major thalassemia. materials and methods sixty-six patients with major thalassemia were studied in amir kabir hospital, arak, iran. serum ferritin levels were...

A 38-year-old man was admitted with coingestive heart failure due to infective endocarditis. Echocardiography with color Doppler imaging revealed severe aortic regurgitation, mitral valve premature closure and diastolic mitral regurgitation. The flow of the diastolic mitral regurgitation was directed to the posterior wall of the left atrium through just behind the posterior mitral leaflet. The ...

OBJECTIVES To determine normal values for variables of left ventricular diastolic function in children measured by Doppler echocardiography and their relations to body surface area (BSA). BACKGROUND There is increasing interest in echocardiographic assessment of left ventricular diastolic function in children but normal data for children are limited. METHODS Assessment of left ventricular d...

background: cardiac rehabilitation is known as a powerful non-pharmacological approach for improving functional capacity, and left ventricular systolic function; however, some limited data have suggested an attenuation of the decline in diastolic function with this program. this study investigated the effect of high intensity aerobic exercise following coronary artery bypass surgery (cabg) on d...

OBJECTIVE The relationship of mitral annular (MA) kinetics to left ventricular (LV) and left atrial (LA) function before and after mitral valve (MV) repair has not been well studied. Here we sought to provide comprehensive analysis that relates to MA motions, and LA and LV diastolic function post MV repair. METHODS Three-dimensional analyses of mitral annular motion, LA function, and LV volum...
