✦ Synopsis

The accuracy of duplex pulsed Doppler echocardiography (d-PDE) for detecting mitral regurgitation was evaluated in 35 patients undergoing d-PDE, cardiac auscultation, and left ventriculography . With three transducer positions, the overall d-PDE sensitivity was 958, specificity was loo%, positive predictive value was loo%, negative predictive value was 949, and diagnostic accuracy was 9 7 9 compared with ventriculography. This technique was superior to auscultation (sensitivity 74%, specificity 94%, positive predictive value 93%, negative predictive value 758, diagnostic accuracy 838). No false-positive d-PDE results occurred, but discordant falsenegative results occurred frequently among the three transducer positions. If discordant negative results are considered to be false negatives, then d-PDE is both sensitive and specific when mitral regurgitation is defined as systolic spectral broadening in any one transducer position.
