The following 3 echocardiographic findings are indicative of severe aortic stenosis:

  • An echo-dense aortic valve with no cusp motion (may be unreliable in congenital or rheumatic valvular stenosis)

  • A decrease in the maximal aortic cusp separation (< 8 mm in the adult)

  • The presence of otherwise unexplained LV hypertrophy
