Background Recent studies have shown that many instrument and physiological factors limit
the ability of color Doppler total jet area within the receiving chamber to predict the severity …

BACKGROUND The ability of transesophageal color Doppler echocardiography to provide
high-resolution images of both cardiac structure and blood flow in real time is advantageous …

This study was performed to test the hypothesis that measurements of jet area by Doppler
color flow imaging can predict the angiographic severity and hemodynamic consequences …

Objectives. To determine the influence of jet eccentricity and mechanism of mitral
regurgitation, we examined 1) the relation between jet extent and severity of mitral …

Objectives. This study was designed to assess the most accurate and reproducible methods
to quantitate mitral regurgitation by color flow trarasthoracic and transesophageal …

BACKGROUND In clinical color Doppler examinations, mitral regurgitant jets are often
observed to impinge on the left atrial wall immediately beyond the mitral valve. In …

Early studies using Doppler color flow imaging have suggested that measurement of the
regurgitant jet area provides information regarding the severity of valvular insufficiency. This …

Doppler evaluation of mitral regurgitation remains difficult; thus, a head-to-head comparison
of the diagnostic accuracy of Doppler methods was undertaken. Fifty patients with native …

Objective To compare the proximal convergence method for quantification of mitral
regurgitation with findings on concomitant left ventriculography. Material and Methods In 41 …

Assessment of the severity of mitral regurgitation (MR) by Doppler color flow mapping is
limited by dependence of jet area on hemodynamic and technical variables. The width of the …
