Clinical assessment of myocardial ischemia based on visually-assessed wall motion scoring from echocardiography is semiquantitative, operator dependent, and heavily weighted by operator experience and expertise. Cardiac motion estimation methods such as tissue Doppler imaging, used to assess myocardial muscle velocity, provides quantitative parameters such as the strain-rate and strain derived ...

OBJECTIVE This study was designed to assess right ventricular systolic and diastolic function and its relationship with grade of hepatosteatosis (HS) in non-alcoholic fatty liver disease (NAFLD) patients using conventional and tissue Doppler echocardiography. METHODS NAFLD was diagnosed in 32 individuals (15 males, 17 females; 59% were grade I HS, 41% grade II-III HS) by means of ultrasonogra...

the turkmen horse is one of the oldest and purest breeds in the world. there is no information with regards to the normal echocardiographic parameters of this horse regarding to cardiac diseases. pulsed-wave (pw) doppler echocardiography was performed on 42 clinically normal 3- to 15-year-old racing turkmen horses. there were 26 stallions and 16 mares. the left ventricular isovolumetric contrac...

Echocardiography is pivotal in the diagnosis and management of the shocked patient. Important characteristics in the setting of shock are that it is non-invasive and can be rapidly applied.In the acute situation a basic study often yields immediate results allowing for the initiation of therapy, while a follow-up advanced study brings the advantage of further refining the diagnosis and providin...

The value of transesophageal pulsed Doppler echocardiography (PDE) was studied in six patients with competent mitral valve and in 12 patients with angiographically proved mild to moderately severe mitral regurgitation. The results were compared with those from the standard transthoracic method of investigation. The advantages of the esophageal over the transthoracic approach in the detection of...

Background Doppler echocardiography-based techniques are routinely used to assess the heart and ventricular function by measuring blood flow and cardiac tissue velocity profiles. While these measures may similarly be obtained by phase contrast MRI, each require separate acquisitions and subsequent analysis to accommodate for vastly different velocities and therefore velocity encoding (VENC) val...

Doppler echocardiography (DE) is known to be a valuable tool for detecting subclinical forms of valvular regurgitation (VRJ in theacutephase of rheumatic fever (RF). Previous studies have mostly dealt with the acute phase problem with only short-term follow-up. In this study, 24 children between 4-15 years of age (mean age II.X±2.7 years) with RF without clinically diagnosed carditis (most ...
