title: Preliminary observations on interventricular septum vibrations: an echocardiographic sign in aortic valvular stenosis.
abstract: In previous experimental and clinical studies on aortic valvular stenosis it has been suggested that in addition to the degree of stenosis, other factors, such as the pathoanatomy of the valve and turbulence-induced vibrations, might be of importance. Using echocardiography, vibrations of the interventricular septum were demonstrated in six consecutive patients with congenital aortic stenosis. In comparable normal subjects no such vibrations could be seen. The clinical significance of ventricular wall vibrations has not yet been established.
