Abstract

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 per cent) were missed by auscultation. Echo missed 20 (41 per cent), and Doppler missed seven (14 per cent). Only two (4 per cent) 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.
