Cineradiographic Studies of the Early Systolic Click in Aortic Valve Stenosis.

sul'0 consider that it originates in the aortic valve. Further recent studies have favored the valvular hypothesis.11' 12 WVe have recorded heart sounds simultaneously with hemodynamic and cineradiographic studies in a series of patients with aortic valvular stenosis in order to relate the early systolic sound to pressure changes and to movements of the aortic valve. The purpose of this paper is to present further evidence for the valvular origin of the early systolic click in aortic stenosis. Patients with valvular aortic stenosis can be classified by cineradiography on the basis of the mobility of the valve.13 14 There appears to be a continuous gradation from the
