Evaluation of Left Ventricular Systolic and Diastolic Global Function: Peak Positive and Negative Myocardial Velocity Gradients in M‐Mode Doppler Tissue Imaging

Abstract

Peak positive and negative MVG are sensitive and load-insensitive indicators of left ventricular function.

Early cardiac morphologic and functional changes in neurofibromatosis type 1 hypertensives: an echocardiographic and tissue Doppler study

“…This finding is in agreement with previous studies demonstrating a significant reduction in those velocities in hypertensive patients with normal global function by conventional parameters compared with healthy subjects [21]. Since S m is significantly correlated with dP/dT [21,25], the presence of a significant decline in myocardial systolic velocity in NF1 hypertensives, when compared with normotensives, could be of great value in the long-term follow-up of those patients since life expectancy in NF1 is conditioned not only by malignancy but also by hypertension [8,9,24].…”

Quantitative assessment of systolic and diastolic ventricular function with tissue Doppler imaging after Fontan type of operation

“…Tissue Doppler imaging (TDI) is a new echocardiographic technique that records myocardial velocities during the cardiac cycle [12][13][14]. Both the systolic and diastolic velocities can be recorded quantitatively by TDI and thereby provide a new way of assessing ventricular function.…”

The Evaluation of Left Ventricular Systolic and Diastolic Functions in Patients With Friedreich Ataxia A Pulse Tissue Doppler Study

“…23) Mori, et al showed that MVG parameters in the short-axis direction were more sensitive than mitral annulus velocity in patients with Duchenne's progressive muscular dystrophy. 24) However, MVG is affected by regional left ventricular wall motion and is especially useful in assessing myocardial tissue characteris- tics.…”
