Echocardiographic assessment of left ventricular function.
The concept of "normalized velocity" has been applied in this study to the echocardiographic (echo) assessment of left ventricular (LV) function in 87 patients. The following normalized velocities were calculated from the ultrasound recording of LV wall motion: 1) the mean circumferential fiber shortening rate (mean VCF), 2) the mean normalized posterior wall velocity (Vpw), and 3) the mean nor...
متن کاملEchocardiographic Assessment of Left Ventricular Diastolic Function
J Echocardiogr Vol.6, No.3, 2008 57 The concepts for the assessment of left ventricular (LV) diastolic function were established in the cardiac catheterization laboratory and necessitate the use of high fidelity pressure and conductance catheters. The most recent [1] set of criteria (Figure 1) for diagnosing diastolic heart failure (DHF) include the presence of increased LV filling pressures (m...
متن کاملPrognostic implications of qualitative assessment of left ventricular function compared to simple routine quantitative echocardiography.
OBJECTIVE To compare the prognostic value of qualitative estimates of left ventricular function with that of routine simple quantitative indices used in echocardiography. DESIGN Retrospective follow up study. SETTING University hospital. PATIENTS The records of 2,964 patients who had undergone echocardiography and who could be traced on the family health services register were examined; 9...
متن کاملQuantitative assessment of left ventricular diastolic stiffness in man.
An approach to the quantitative assessment of left ventricular (LV) diastolic stiffness in man has been developed utilizing strip-chart recordings of simultaneous ultrasonic LV dimensions, LV pressure, and electrocardiogram (ECG). In 23 patients without regional abnormalities of contraction, LV pressure, and LV internal diameter (D = distance between endocardial surfaces of LV posterior wall an...
متن کاملQuantitative cardiac MR assessment of left ventricular diastology
Background Cardiac MR (CMR) is the accepted gold standard for the assessment of myocardial scar and biventricular systolic function. Bright blood cine imaging with phase-contrast mitral inflow assessment has shown promise for the evaluation of left ventricular (LV) diastology. The purpose of this study is to evaluate the accuracy of LV diastolic function grading by CMR, using Doppler echocardio...
