## Abstract We describe a series of patients with suspected aortic stenosis who were noted to have a significant aortic valve gradient by Doppler echocardiography but only a minimal gradient during cardiac catheterization. Although the pressure recovery phenomenon partially explained this discrepan

Abstract
Sixtyβfive patients were studied for the presence of aortic insufficiency by auscultation, conventional M mode echocardiography (echo), rangeβgated 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.

## Abstract Pulsed Doppler echocardiography and digital Fourier analysis were utilized to examine flow distal to the aortic valve and to quantify aortic stenosis. A graphic index of parameters derived from velocity spectrum patterns generated by Fourier analysis was regressed against mean systolic
