Tissue Doppler imaging in cardiac sarcoidosis [PDF]

European Heart Journal - Cardiovascular Imaging, 2008
A middle-aged African lady, who presented with ventricular tachycardias, mitral valve regurgitation and congestive heart failure, was diagnosed with cardiac sarcoidosis. Tissue Doppler imaging demonstrated abnormalities suggestive of myocardial scar, which was confirmed by contrast-enhanced cardiac magnetic resonance.

Hypercholesterolemia and Myocardial function evaluated via Tissue Doppler Imaging

Cardiovascular Ultrasound, 2009
Objective To establish a link between hypercholesterolemia and myocardial dysfunction. Background Heart failure is a complex disease involving changes in systolic and diastolic function.

Quantification of left ventricular longitudinal strain, strain rate, velocity and displacement in healthy horses by 2-dimensional speckle tracking [PDF]

, 2011
Background: The quantification of equine left ventricular (LV) function is generally limited to short-axis M-mode measurements. However, LV deformation is 3-dimensional (3D) and consists of longitudinal shortening, circumferential shortening, and radial ...

Right ventricular function assessment in single LAD lesion patients using strain and strain rate imaging

Alexandria Journal of Medicine, 2016
Background: Strain and strain rate imaging is currently the most popular echocardiographic technique that reveals subclinical myocardial damage, and data are not available on this imaging method with regard to assessing right ventricular involvement in ...

Interpretation of Annular Tissue Doppler Imaging [PDF]

Korean Circulation Journal, 2011
Refer to the page 137-142 Diastolic dysfunction has become a more predominant form of heart failure (HF) than systolic dysfunction in the community. However, diastolic dysfunction is not always related to HF. Diastolic HF is defined as HF with preserved left ventricular (LV) systolic function, usually a LV ejection fraction (EF) of more than 50%, in

Tissue Doppler echocardiography and biventricular pacing in heart failure: Patient selection, procedural guidance, follow-up, quantification of success

Cardiovascular Ultrasound, 2004
Asynchronous myocardial contraction in heart failure is associated with poor prognosis. Resynchronization can be achieved by biventricular pacing (BVP), which leads to clinical improvement and reverse remodeling. However, there is a substantial subset of
