Detection of mitral regurgitation by Doppler ultrasound. A comparison with left ventricular angiography.


Sixty-four patients with various heart diseases were evaluated for mitral regurgitation (MR) by left ventricular angiography and pulsed Doppler ultrasound within 2-3 days. Adequate Doppler recordings were obtained from 60 patients. The sensitivity of Doppler in detecting MR was 94%, specificity 90% and predictive value for a positive and a negative Doppler… (More)
