Key result
Congenital aortic stenosis is linked to systolic interventricular septal vibrations absent in non-valvular heart enlargement.
Why the study?
Are systolic vibrations of the interventricular septum associated with congenital aortic valvular stenosis and its severity?
Observational (n=38)
Are systolic vibrations of the interventricular septum associated with congenital aortic valvular stenosis and its severity?
Systolic vibrations of the interventricular septum may serve as a physiological marker for the presence and severity of congenital aortic valvular stenosis.
May indicate septal vibrations as marker for congenital aortic stenosis severity; hypothesis-generating and requires prospective validation.
Systolic vibrations of interventricular septum are described in 30 patients with congenital aortic valvular stenosis. No such vibrations were found in 8 patients with similar enlargement of the heart but without valvular defects. The frequency and amplitude of vibrations seem to correlate with the severity of aortic valvular stenosis, degree of dilatation, hypertrophy and filling pressure of the left ventricle.

Vukas et al. (1981) conducted an observational in Congenital aortic valvular stenosis (n=38). Congenital aortic valvular stenosis vs. Similar enlargement of the heart without valvular defects was evaluated on Systolic vibrations of interventricular septum. Systolic vibrations of the interventricular septum were found in 30 patients with congenital aortic valvular stenosis but were absent in 8 patients with heart enlargement without valvular defects.
