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...

turkmen horse is one of the oldest and purest breeds in the world, but there is no information on doppler echocardiographic parameters in this horse. in the present study, pulsed-wave (pw) doppler echocardiography was performed on 42 clinically normal 3- to 15-year-old racing turkmen horses. no cardiac disease was detected with two-dimensional (2-d) real-time, m-mode, and colour flow mapping. d...

We report the cases of 2 patients who presented with clinical and echocardiographic evidence of cardiac tamponade. Therapeutic echocardiographic-guided pericardiocentesis yielded bloody fluid. In both patients, Definity perflutren lipid microspheres were used for echocardiographic contrast, which helped to assess the needle's location. To the best of our knowledge, this is the 1st reported use ...

OBJECTIVES The purpose of this study was to investigate the prognostic value of global longitudinal strain (GLS) in heart failure with reduced ejection fraction (HFrEF) patients in relation to all-cause mortality. BACKGROUND Measurement of myocardial deformation by 2-dimensional speckle tracking echocardiography, specifically GLS, may be superior to conventional echocardiographic parameters, ...

Endocardial border detection is a crucial step for the quantitative analysis of overall and regional left ventricular function from echocardiographic images. Echocardiographic contrast agents with transpulmonary passage are being used increasingly in clinical practice for left ventricular cavity opacification. We investigate the feasibility of using pulse coupled neural networks to identify the...

BACKGROUND With the advent of three-dimensional (3D) printers and high-resolution cardiac imaging, rapid prototype constructions of congenital cardiac defects are now possible. Typically, source images for these models derive from higher resolution, cross-sectional cardiac imaging, such as cardiac magnetic resonance imaging or computed tomography. These imaging methods may involve intravenous c...

S ignificant acute hemodynamic changes occur in pilots upon transient exposure to high gravity forces (+G,).’ It is not well established, however, whether frequent repeated exposure to high values (up to 9) of acceleration stress may induce structural cardiovascular changes. A French study’ performed among 32 pilots flying high +G, revealed a statistically significant increase in left atria1 di...

surgery or autopsy. Unusual echocardiographic findings early in the course of the disease in a patient we studied recently led us to suspect the diagnosis of a ruptured left coronary cusp. When these were noted to correlate with clinical deterioration, immediate cardiac catheterization and aortic valve replacement was undertaken. The echocardiographic features of aortic valve endocarditis have ...

We studied 130 patients undergoing percutaneous balloon mitral valvotomy. The relation between valvular morphology according to a previously described echocardiographic scoring system and hemodynamic outcome expressed as qualitative ("good" and suboptimal) and as absolute change in valve area was analyzed. The relative importance of the individual components of this echocardiographic score (val...
