Assessment of transesophageal pulsed Doppler echocardiography in the detection of mitral regurgitation.

Assessment of pulsed Doppler echocardiography in detection and quantification of aortic and mitral regurgitation.

Pulsed Doppler echocardiography was employed to detect disturbed or turbulent flow diagnostic of aortic or mitral regurgitation. Sensitivity, specificity, diagnostic accuracy, and predictive value were assessed by the independent interpretation and comparison of aortic root angiograms (91 patients) and left ventriculograms (94 patients) to the time interval histogram display of the pulsed Doppl...

Quantitative Assessment of Mitral Regurgitation: Comparison Between Three-dimensional Transesophageal Echocardiography and Magnetic Resonance Imaging Running Title: Shanks et al: Mitral regurgitation quantification: 3D TEE vs. MRI

Assessment of Severit of Mitral Regurgitation by Measuring Regurgitant Jet Width at Its Origin With Transesophageal Doppler Color Flow Imaging

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 for many clinical purposes. This study was performed to determine the utility of the regurgitant jet width at its origin measured by transesophageal Doppler color flow imaging in the assessment of severity of mitral reg...

Detection and estimation of the degree of mitral regurgitation by range-gated pulsed doppler echocardiography.

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 depth and width of the regurgitant jet detected with Doppler and compared with that assessed by left ventriculography. Of 47 patients with an adequate Doppler study, 24 had no mitral regurgitation by ventriculography....

Cardiac Valve Prostheses

To determine the value of transesophageal ultrasound in the assessment of cardiac valve prostheses, 14 patients with clinically suspected mitral prosthesis malfunction were studied by transthoracic and transesophageal two-dimensional imaging as well as by color Doppler flow velocity mapping (color Doppler). Patients underwent left ventricular angiography (n = 13), surgery (n =11), or both angio...
