Evaluation of the effect of mitral stenosis severity on the left ventricular systolic function using isovolumic myocardial acceleration.
BACKGROUND Isovolumic acceleration (IVA) is a new tissue Doppler parameter in the assessment of systolic function of both left and right ventricles. It remains unaffected with the changes in pre- and after-load within the physiological range. The aim of our study was to assess the effect of mitral stenosis degree, which is determined by echocardiography, on the left ventricular (LV) function us...
متن کاملLEFT VENTRICULAR DIASTOLIC ABNORMALITIES IN β-THALASSEMIA MAJOR WITH NORMAL SYSTOLIC FUNCTION
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 velocit...
متن کاملNormal Value of Left Ventricular End-Systolic Elastance in Infants and Children
Background: In certain conditions, there is a need for a specific and improved measure of cardiac performance. Routine methods for assessing left ventricular (LV) function are based on image-analysis or right heart monitoring which do not allow evaluation of ventriculo-arterial interaction. Chen et al presented a noninvasive method allowing measurement of end-systolic pressure–volume relation ...
متن کاملEffects of the intracoronary infusion of cocaine on left ventricular systolic and diastolic function in humans.
BACKGROUND In dogs, a large amount of intravenous cocaine causes a profound deterioration of left ventricular (LV) systolic function and an increase in LV end-diastolic pressure. This study was done to assess the influence of a high intracoronary cocaine concentration on LV systolic and diastolic function in humans. METHODS AND RESULTS In 20 patients (14 men and 6 women aged 39 to 72 years) r...
