A transcutaneous Doppler velocity probe was used to record phasic carotid artery flow in 12 patients with hypertrophic subaortic stenosis. In contrast to the normal Doppler flow pattern of a single large orthograde systolic wave, all patients demonstrated a distinctively abnormal flow profile. A sharp wave of rapid, early systolic flow was followed by an abrupt decrease of flow in midsystole with a slower phase of late systolic flow. In 4 of the 12 patients the distinctively abnormal Doppler flow pattern was found in the absence of the characteristic sharp percussion and low tidal wave carotid pulse contour often present in hypertrophic subaortic stenosis. The Doppler recording of phasic carotid flow seems valid for the clinical evaluation of this disease, since the abnormal abrupt decrease in midsystolic flow was not found in the study of 94 patients presenting with other cardiovascular disease.
