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 …

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

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 …

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

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 …

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 …

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

Transesophageal echocardiography (TEE) was performed within 24 hours after cardiac
catheterization in 45 patients for assessment of native mitral valvular regurgitation. Color …

Background Quantitative Doppler echocardiography and proximal flow convergence
methods are validated techniques for quantifying mitral regurgitation. However, the clinical …

OBJECTIVE--To assess the usefulness of pulsed Doppler echocardiography as a method of
measuring the regurgitant fraction in patients with mitral regurgitation. PATIENTS AND …
