Technological advances in tissue Doppler imaging echocardiography

Heart, 2008
Tissue Doppler imaging is a recently introduced echocardiographic tool for measuring myocardial velocities. In this article the physical principles and different myocardial velocity imaging modalities are discussed. Examples of practical applications and clinical use of this non-invasive imaging technique are provided.

Tissue Doppler imaging in rheumatic carditis

Cardiology in the Young, 2008
AbstractObjectiveOur study was undertaken to assess cardiac functions by tissue Doppler echocardiography in patient with primary episode of rheumatic carditis.MethodsWe divided 82 patients with rheumatic carditis were divided in two groups; 50 patients with mild and 32 patients with mitral regurgitation of grade two or more.

Tissue Doppler imaging in the normal fetus

International Journal of Cardiology, 1999
Tissue Doppler imaging is a new non-invasive method that derives measurements of relaxation velocities directly from the myocardium. This approach to studying myocardial velocities offers the potential for quantitative assessment of diastolic ventricular function. Data on myocardial tissue velocities in normal fetuses have not been established.

Application of Tissue Doppler Imaging in Cardiology

Cardiology, 2004
Tissue Doppler imaging (TDI) is a new echocardiographic technique employing the Doppler principle to measure the velocity of myocardial segments and other cardiac structures. It is well suited for the measurement of long-axis ventricular function. Impairment of longitudinal myocardial fiber motion is a sensitive marker of early myocardial dysfunction ...

Pulsed doppler tissue imaging in dystrophinopathic cardiomyopathy

Journal of the American Society of Echocardiography, 2002
Cardiac dysfunction is a primary feature in patients and female carriers of Becker muscular dystrophy (BMD). Conventional echocardiography and pulsed Doppler tissue imaging (DTI) were performed in 28 patients with BMD, in 20 female carriers, and in 38 control participants (20 men and 18 women). Left ventricular ejection fraction (LVEF) was lower in BMD

Tissue Doppler imaging and the quantification of myocardial function

The International Journal of Cardiac Imaging, 1998
Tissue Doppler imaging (TDI) has recently been introduced in clinical echocardiography. Most widely used are tissue velocity maps, in which the velocity of moving tissue is calculated relative to the transducer from the Doppler shift and displayed as colour-encoded velocity maps in either M-mode or two-dimensional image formats (Doppler velocity mode).

Tissue Doppler Imaging Reproducibility during Exercise

International Journal of Sports Medicine, 2008
Tissue Doppler imaging (TDI) is an echocardiographic technique used during exercising to improve the accuracy of a cardiovascular diagnostic. The validity of TDI requires its reproducibility, which has never been challenged during moderate to maximal intensity exercising. The present study was specifically designed to assess the transmitral Doppler and

Doppler tissue imaging of the heart in secondary amyloidosis

Advances in Therapy, 2005
Secondary amyloidosis (SA) affects cardiac texture and function by interstitial fibrosis. Doppler tissue imaging (DTI) may quantify heart function through the assessment of myocardial velocities. Echocardiographic findings of early cardiac amyloidosis (CA) without heart failure (HF) caused by SA were determined both by standard methods and DTI.

Cardiac Tissue Doppler Imaging in Sports Medicine

Sports Medicine, 2007
The differentiation of training-induced cardiac adaptations from pathological conditions is a key issue in sports cardiology. As morphological features do not allow for a clear delineation of early stages of relevant pathologies, the echocardiographic evaluation of left ventricular function is the technique of first choice in this regard.

[Doppler tissue imaging in myocardial infarction].

Minerva cardioangiologica, 2001
The Doppler Tissue Imaging (DTI) is a recent Doppler method that allows to measure the velocities of myocardial walls. Thus, DTI may analyse myocardial contraction and give a quantitative evaluation of systolic and diastolic function. The aim of the study is to appraise the myocardial contraction of the left ventricle in patients with a recent ...
