Résumé : | In order to assess the value of pulsed Doppler echocardiography in detection of valvular regurgitation, 63 patients were evaluated for aortic and/or mitral regurgitation using pulsed Doppler echocardiography and selective cineangiography. The Doppler study was considered as positive when a turbulent flow was detected below the aortic valve for aortic insufficiency and behind the mitral valve for mitral insufficiency on a graphic display (time interval histogram) when technically adequate and/or on an audiosignal. These results were compared with standard angiographie evaluation of the regurgitation: echocardiography had 94% sensitivity and the specificity rate was very high (87.5%) even for mild regurgitation. Thus, Doppler technique is highly specific and sensitive in detection of aortic and mitral regurgitation when both audiosignal and time-interval histogram are simultaneously performed. |
