Aortoseptal angulation and left ventricular hypertrophy pattern: an echocardiographic study in patients with aortic valvular stenosis.

We studied 15 patients with valvular aortic stenosis (mean age 63 +/- 14 [SD] years) with M-mode, two-dimensional, and Doppler echocardiography to evaluate the influence of aortoseptal angulation on left ventricular changes. The diastolic aortoseptal angle averaged 118 degrees +/- 4 degrees in 10 patients (group I) and 96 degrees +/- 17 degrees in five patients (group II) (p less than 0.05).
