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 …

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 …

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 …

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 …

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 …

Eighty consecutive patients who underwent both left ventriculography and single-plane
transesophageal echocardiography with Doppler color flow mapping were studied to …

To test the role of recently developed biplane transesophageal color Doppler
echocardiography in the assessment of severity of mitral regurgitation, we examined 51 …

Color Doppler echocardiography does not provide adequate information about the severity
of mitral regurgitation in patients with eccentric mitral regurgitation. We have developed a …

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 …

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 …
