Standard echocardiography versus handheld echocardiography for the detection of subclinical rheumatic heart disease: A systematic review
… needed in many endemic areas. Recently, handheld echocardiography has become widely available with a variety of clinical uses. If shown to be sufficiently accurate, use of these handheld devices could potentially expand access to echocardiographic screening in RHD endemic areas. The research …

Volumetric Acoustic Radiation Force Impulse Imaging Using Intracardiac Echocardiography
<p>Intracardiac echocardiography (ICE) based elastography methods have the potential to be useful for a number of clinical purposes including monitoring of ablation lesion formation and myocardial substrate characterization. However, 2-D field-of-view ICE catheters currently in use in the clinic …

Impact of basic transthoracic echocardiography at district hospital level
The use and demand of echocardiography has increased worldwide. In developed countries, this has not been translated into improved access outside tertiary centres. Previous studies have favoured the appropriate use of echocardiography over its clinical impact, limiting generalisability to resource …

The role of contemporary echocardiography in the management of heart failure
… morbidity, hospitalisation and death. Echocardiography is often used in HF patients because it provides important aetiological, diagnostic and prognostic information to assist physician management at moderate cost. This thesis has explored contemporary echocardiographic techniques for …

Three-dimensional echocardiography for the assessment of congenital and acquired heart disease
… two-dimensional and Doppler blood-flow echocardiography are the standard imaging approaches in the assessment of heart disease they do not provide anatomic reconstructions in a form that resembles the cardiac morphology as visualized by the surgeon.

Determinants of left ventricular mass as measured by Doppler echocardiography in pre-adolescents
… in left ventricular mass as measured by Doppler echocardiography in children. Fourteen boys (10.3 ± 0.3 years of age) and 1 1 girls (10.5 ± 0.4 years of age) participated in the study. Height and weight were measured, and relative body fat was determined from the measurement of skinfold thickness …

Quantitative Hydrodynamics Analysis of Left Ventricular Diastolic Dysfunction using Color M-Mode Echocardiography
… caused by this disease. Color M-mode (CMM) echocardiography is a technique that is commonly used in the diagnosis of Left Ventricular Diastolic Dysfunction (LVDD) and is used as the image modality in this work. The motivation for the current work is a hypothesized change in the mechanism …

Quantification of cardiac structure and function using transthoracic echocardiography in term women with HIV
… to quantify haemodynamics using transthoracic echocardiography (TTE) in term pregnant women with HIV on antiretroviral (ARV) treatment and compare the data with term healthy women in the same population. Method: After ethics approval and written consent, 30 consecutive term HIV positive women …

The diagnostic ability of pediatric transthoracic echocardiography in the current era : a segmental appraisal
Transthoracic echocardiography (TTE) plays a crucial role in the care of pediatric patients with heart disease. However, despite numerus recent technological advances, there has been little re-assessment of its accuracy. We sought to systematically assess the diagnostic accuracy of pediatric TTE in …

Comparison of echocardiography and computed tomography for characterization of cardiac clots in cats with heart disease
… cats most commonly secondary to heart disease. Echocardiography is the reference standard to evaluate for presence of a clot or its precursor known as spontaneous echocardiographic contrast (SEC or “smoke”) within the left atrium and left auricle. In humans, trans-esophageal echocardiography …

Determination of cardiac output across a range of values in horses by M-mode echocardiography and thermodilution
Determinations of cardiac output (CO) by M-mode echocardio-graphy were compared with simultaneous determinations by thermodilution in 2 conscious and 5 anesthetized horses. A range of cardiac outputs was induced by use of a pharmacological protocol (dopamine, 4 ug/kg/min, dobutamine, 4 ug/kg/min, …

The Impact of Prolonged Strenuous Exercise on Right Ventricular Structure and Function: Insights from Novel Echocardiography and Electrocardiography
The body of evidence investigating post-exercise changes in left (LV) and right ventricular (RV) structure and function, commonly referred to as exercise induced cardiac fatigue (EICF), demonstrates a reduction in both systolic and diastolic function. RV dilatation and reduced LV filling are also …

Characterization of Cardiomyopathy in a Mouse Model of Duchenne Muscular Dystrophy (DMD) Using Echocardiography, DCE-CT, and PET-FDG
… tomography-fluorodeoxyglucose (PET-FDG), echocardiography, and traditional histology to longitudinally assess disease progression and degree of cardiomyopathy in a murine model of DMD (mdx:utrn-/-). No significant changes were observed in the blood flow, blood volume, or cardiac volume …

The impact of point-of-care transthoracic echocardiography on management of patients presenting for emergency surgery in a resource-limited setting
… the impact of routine preoperative transthoracic echocardiography on perioperative management. Design: A prospective before- and after-study of adult patients presenting for emergency, non-cardiac, non-obstetric surgery. Setting: The study was performed at an academic hospital in Cape Town, South …
