Abstract/OtherAbstract:
This paper reports a safe, noninvasive and accurate method for estimating aortic regurgitation. It is possible to detect some quantitative features of the disease from the velocity information obtained from the common carotid artery with the bi-directional velocimeter (model F1) developed by the authors. The diastolic murmur over the aortic region is a quantitative feature of the disease. With the theory of quantification I, both qualitative and quantitative variables were processed. A prediction formula was obtained to assess the degree of aortic regurgitation. The results of such predictions in 15 normal subjects and 25 patients are given. All the patients underwent retrograde aortography or operation to provide comparison with the ultrasonic measurements.
