The combination of auscultation and pulse Doppler echocardiography is a highly sensitive noninvasive method for detecting aortic insufficiency.

Auscultation plus Doppler may improve noninvasive aortic insufficiency detection; leaves open whether it warrants prospective validation or practice change.
Sixty-five patients were studied for the presence of aortic insufficiency by auscultation, conventional M mode echocardiography (echo), range-gated pulse Doppler flowmeter (Doppler), and supravalvular aortic angiography. Aortic insufficiency was demonstrated angiographically in 49 patients, of which eight (16%) were missed by auscultation. Echo missed 20 (41%), and Doppler missed seven (14%). Only two (4%) were missed by auscultation and Doppler combined. All methods were highly specific, but the combination of auscultation and Doppler was the most sensitive noninvasive method for detecting aortic insufficiency.
