Pulsed Doppler echocardiography was employed to detect disturbed or turbulent flow
diagnostic of aortic or mitral regurgitation. Sensitivity, specificity, diagnostic accuracy, and …

In order to assess the sensitivity and specificity of the range-gated pulsed Doppler
echocardiogram for the detection of aortic regurgitation, a study with use of this technique …

This study was undertaken to assess the contribution of Doppler echocardiography to the
quantification of aortic valve regurgitation. Ultrasound examination was performed by …

Continuous-wave Doppler echocardiography was used to examine the aortic regurgitant
flow velocity pattern in 32 patients with aortic regurgitation (AR) and 10 patients without AR …

Sensitivity and specificity of detection of mitral regurgitation was assessed by range-gated
Doppler echocardiography. The degree of mitral regurgitation was also estimated by the …

The aortic regurgitant fraction was estimated noninvasively in 20 patients with aortic
regurgitation from systolic aortic and pulmonary volume flow determined by duplex Doppler …

Measurements of mitral and aortic valve flows were obtained with two-dimensional Doppler
echocardiography in 25 patients with isolated mitral (n= 19) or aortic (n= 6) regurgitation and …

The value of Doppler echocardiography for the non-invasive diagnosis of mitral regurgitation
was studied blindly in 161 consecutive invasively investigated adult patients. Regurgitation …

The purpose of this study was to evaluate the ability of continuous wave Doppler ultrasound
recordings to reflect the magnitude and hemodynamic effects of aortic regurgitation. Forty …

Doppler echocardiography is useful for detecting aortic regurgitation (AR). To determine if
the presence of retrograde holodiastolic flow in the abdominal aorta can be used to assess …
