Left ventricular hypertrophy due to aortic stenosis, hypertension and other forms of heart disease is associated with abnormalities of diastolic function. It is uncertain whether these changes are an inherent consequence of the hypertrophic process or represent additional pathologic factors. To investigate this issue, echocardiographic indexes of left ventricular early diastolic function in hig...

BACKGROUND To determine how the tissues that surround the heart affect diastolic and systolic function during the perinatal period, we studied the pressure-diameter relation of the left ventricle in partially delivered fetal lambs. METHODS AND RESULTS We anesthetized (1.5-2.0% halothane, balance O2) and ventilated six pregnant ewes (142-144 days of gestation) and then partially delivered each...

J Echocardiogr Vol.6, No.3, 2008 57 The concepts for the assessment of left ventricular (LV) diastolic function were established in the cardiac catheterization laboratory and necessitate the use of high fidelity pressure and conductance catheters. The most recent [1] set of criteria (Figure 1) for diagnosing diastolic heart failure (DHF) include the presence of increased LV filling pressures (m...

Changes in left ventricular systolic and diastolic function and outflow gradient were evaluated in patients with obstructive hypertrophic cardiomyopathy after intravenous acute treatment with verapamil (15 patients) and after six months of oral chronic treatment (11 patients). All patients had severe symptoms despite beta blockade, and the condition of all but two improved appreciably after chr...

BACKGROUND It is not known whether abnormalities of left ventricular diastolic function are influenced by the various cardiac geometric patterns in Nigerians with newly diagnosed systemic hypertension. OBJECTIVE To evaluate the relationship between the parameters of left ventricular diastolic function and the geometric patterns in this group of patients. METHODS Two-dimensional, guided M-mo...

s Objectives: The aim of this study is to show the effects of left ventricular hypertrophy and geometric patterns on the left ventricular diastolic function in patients with essential hypertension. In addition, it’s aimed to identify whether the diastolic dysfunction is associated with systolic dysfunction. Finally, to determine the occurrence of the diastolic dysfunction in hypertensive patien...

Ventricular function curves were constructed in 39 patients having coronary arteriography by plotting left ventricular end-diastolic pressure and stroke work index before, during, and immediately after atrial pacing. Similar curves were constructed from measurements obtained before and 3 minutes after a standard left ventricular angiogram. Both methods vary preload sufficiently to produce detec...

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...

coronary artery disease is one of the most common causes of mortality and morbidity across the world. its treatment includes medical treatment, coronary artery bypass graft (cabg) and percutaneous coronary intervention (pci). the purpose of this study was to investigate the effect of pci on echocardiographic findings of left ventricular (lv) systolic and diastolic function. 115 patients with co...
