Left Atrial Strain Value Versus Tissue Doppler Echocardiography and the Left Atrium Volume Index in the Evaluation of Left Ventricular Diastolic Function in Patients with Chronic Kidney Disease [PDF]

Clinics and Practice
Background: In heart failure with preserved ejection fraction (HFpEF) and decreased ejection fraction (HFrEF), LA strain, an indicator of the filling and discharge of the left atrium (LA), was recently identified as a sign of diastolic dysfunction.

Basics of tissue doppler revisited

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2017
Tissue Doppler imaging (TDI) records velocities of myocardial tissue. Routinely longitudinal velocities of medial and lateral mitral annulus and lateral tricuspid annulus are evaluated in apical four chamber view.

Measurement of particle flux in a static matrix with suppressed influence of optical properties, using low coherence interferometry [PDF]

, 2010
Perfusion measurements using conventional laser Doppler techniques are affected by the variations in tissue optical properties. Differences in absorption and scattering will induce different path lengths and consequently will alter the probability that a

Doppler tissue imaging [PDF]

ACC Current Journal Review, 1996
Summary Doppler tissue imaging is a novel means of imaging that interrogates high amplitude, low velocity echoes in the range of tissue and myocardial motion. In addition to providing a qualitative aid in edge detection and wall motion analysis, quantitative interrogation of myocardial velocities may provide insights into normal and abnormal systolic

Tissue Doppler Imaging

Journal of the American College of Cardiology, 2007
In der vorliegenden Arbeit wurden Strain und Strain Rate zum ersten Mal in der Veterinärmedizin bei einer großen Population von Hunden eingesetzt. Beide Methoden sind, wie das TVI, Techniken des Gewebedopplers. Dieser basiert auf dem gleichen Prinzip wie der Blutflussdoppler.

Evaluation of Left Ventricular Function in Patients with Systemic Lupus Erythematosus: Association of Tissue Doppler and Strain Imaging with Disease Activity

Journal of Clinical and Preventive Cardiology, 2020
Background: Systemic lupus erythematosus (SLE) is a connective tissue disorder with cardiovascular involvement associated with high morbidity and mortality. Routine echocardiography often misses early myocardial involvement.
