Left ventricular diastolic function in children measured by Doppler echocardiography: normal values and relation with growth.

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...

The influence of Asthma on Right Ventricular Systolic and Diastolic Function in Children according to Tissue Doppler Echocardiography

Introduction:Asthma is the most common chronic inflammatory condition affecting the lower airways among children. Asthma may influence right ventricular (RV) function and patients may develop right ventricular hypertrophy, pulmonary hypertension and cor pulmonale. The main objective of this study is to determine RV dysfunction in asymptomatic asthmatic children as detected by ti...

LEFT 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...

Evaluation of Right Ventricular Function by Tissue Doppler Echocardiography in Asthmatic Children

BackgroundAsthma is the most chronic inflammatory disorder of the airways in children and asthmatic patients can experience cardiac dysfunction, pulmonary hypertension and finally cor pulmonale later in life. We aimed to investigate Right Ventricular (RV) functions in asthmatic children by conventional and tissue Doppler echocardiography (TDE).Materials and Methods Pulmonary function tests, con...

Changes in left ventricular stroke volume measured by Doppler echocardiography.

Cardiac stroke volume was measured simultaneously by Doppler echocardiography and thermodilution in 20 patients with coronary artery disease. Stroke volume as determined by ultrasound was calculated from the area of the aortic orifice and the flow velocity just distal to the aortic cusps. The recordings were made twice at rest. Ten patients were given dobutamine (2.5 and 5.0 micrograms/kg/min) ...
