background pulmonary arterial hypertension (pah) is a serious complication of unrepaired congenital left-to-right shunts. the final consequence is right ventricular (rv) systolic dysfunction and reversal of shunt. objectives the aim of this study was to evaluate the clinical course and paraclinical findings in a group of patients with pah associated with congenital heart disease (pah-chd). we a...

background: the aim of the study is to determine the correlation between clinical and echocardiographic fi ndings and risk factors of patients with suspected acute pulmonary thromboembolism (pte) who underwent computed tomography pulmonary angiography (ctpa). materials and methods: in this cross-sectional study, 310 hospitalized patients aged >18 years with high clinical suspicion of pte referr...

This report describes the echocardiographic features seen in a case of bacterial endocarditis in which the aortic valve leaflets had been partially destroyed. The echocardiogram demonstrated unusual, disorganized echo patterns in the outflow tract of the left ventricle near the anterior leaflet of the mitral valve in diastole. These were shown to be continuous with similar disorganized echo pat...

The echocardiograms of two patients with sclerodermatous cardiac disease are described. In one patient the pattern was that of a congestive cardiomyopathy with ventricular dilatation and reduced wall motion. In the second patient the pattern was that of an infiltrative cardiomyopathy with thickened walls and reduced wall motion in the absence of ventricular dilatation. Echocardiographic studies...

This article addresses the current state of the art of technology in three-dimensional echocardiography as it applies to transducer design, beam forming, display, and quantification. Because three-dimensional echocardiography encompasses many technical and clinical areas, this article reviews its strengths and limitations and concludes with an analysis of what to use when.

Echocardiography has advanced significantly since its first clinical use. The move towards more accurate imaging and quantification has driven this advancement. In this review, we will briefly focus on three distinct but important recent advances, three-dimensional (3D) echocardiography, contrast echocardiography and myocardial tissue imaging. The basic principles of these techniques will be di...

Evolution of two-dimensional and color Doppler echocardiography identified the typical features of Endomyocardial Fibrosis (EMF) such as dense ventricular apical fibrosis, dysfunction of atrioventricular valve and sub-valvular apparatus and cavity dimensions. This is the tool used most for the diagnosis of EMF in areas where the disease is endemic in Africa. Today echocardiography is used as a ...

This study was undertaken to assess both the relation between echocardiographic measurement of left ventricular (LV) mass and commonly used electrocardiographic criteria for LV hypertrophy and the effect of the distance from the center of LV mass to the anterior chest wall on precordial voltage. Echocardiograms and standard 12-lead electrocardiograms were obtained on 100 persons, ages 3 to 79. ...

A 72-year-old man with calcific aortic stenosis and complete heart block was noted to have an intermittent diastolic murmur. Using combined echocardiography and phonocardiography, it was demonstrated that the murmur occurred while the mitral valve was closing. This suggested that antegrade flow across a closing mitral orifice is of etiologic importance in the production of the murmur. Atrial so...

background: determining the clinical significance of cardiac murmurs is widely considered in equine practice. pulmonary murmurs are commonly detected in athletic horses. echocardiography plays a leading role in assessment of these murmurs. objectives: echocardiographic evaluation of horses with pulmonary regurgitation and determining the importance of pulmonary valve murmurs. methods: a total n...
