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...

Objective- to determine the range of systolic times intervals using Pulsed-wave Doppler and m-mode echocardiography in normal, healthy Great Dane dogs. Design- Descriptive study. Animals- Thirty healthy Great Dane dogs. Procedures- This study examined 30 clinically healthy Great Dane dogs by the twodimensional, M-mode and Pulsed-wave Doppler echocardiography. The dogs were awake and unsedated. ...

doppler ultrasound can provide important information about vascular problems through the analysis of blood flow wave-form. the purpose of this study was obtaining the normal images of color doppler and estimation of blood flow velocity parameters of femoral artery in rabbits. left and right femoral arteries of 8 healthy adult new zealand rabbits were evaluated. color and spectral doppler images...

INTRODUCTION AND OBJECTIVES To analyze the profile of left atrial wall velocities by pulsed wave tissue Doppler imaging, and to compare the relationship between these observations and the transmitral and pulmonary vein flow velocities obtained by conventional pulsed Doppler echocardiography. PATIENTS AND METHOD We studied 90 patients (50 women and 40 men, mean age 48 [22] years). Pulsed tissu...

AIMS This study applies pulsed wave Doppler tissue imaging and colour Doppler tissue imaging to study changes in atrial function with ageing. We tested the following hypotheses: (1) pulsed wave Doppler tissue imaging can detect global changes of left atrial function associated with ageing similar to standard echocardiographic methods, (2) colour Doppler tissue imaging can reproducibly detect re...

Twenty patients with ventricular septal rupture after myocardial infarction were investigated by cross sectional echocardiography with integrated pulsed and continuous wave Doppler and colour flow mapping. Confirmatory cardiac catheterisation was performed in 12 patients. Eighteen patients had surgical repair with inspection of the defect. Six patients in whom recurrent ventricular septal ruptu...

Doubly committed subarterial (supracristal) Residual VSD (by color and pulsed-wave Doppler and with contrast), although small leaks are acceptable at the borders of the patch. Residual or new aortic insufficiency compared with prebypass findings. RVOT obstruction or pulmonary regurgitation. Minimal PI may be acceptable. Muscular, Apical, Inlet Residual VSD (by color and pulsed-wave Doppler and ...

In the 1980s, the development of Doppler echocardiography, especially pulsed wave Doppler techniques, provided significant progress in determining cardiac flow volumes. The pulsed wave Doppler method is based on a simple mathematical principle, which multiplies a flow area by its velocity during the flow time (velocity–time integral) to estimate a flow volume. This Doppler method assumes a spat...

t a fi d T t p n r r l fi w N of Diagnostic and Interventional Imaging, to an emerging technique: ultrasound elastography. This issue provides the readers with information necessary to understand this new modality on the eve of its clinical expansion. Analogies with the development of pulsed wave and color Doppler modes are important, especially for techniques providing two-dimensional color-co...
