The New Eng land Jour nal of Medicine pertrophy, and an aortic-valve area of less than 0.6 cm 2 or an aortic-valve index no higher than 0.6 cm 2 per square meter of body-surface area). 2 However, none of these echocardiographic findings have demonstrated the predictive power that Rosenhek et al. report for the degree of valvular calcification and the increase in aortic-jet velocity. Their results add to the existing evidence that an absence of symptoms is an insufficient reason to delay aortic-valve replacement in certain cases. The findings also shed light on the matter of which patients should be considered for early surgery.
