Clinical exam findings useful for ruling in aortic stenosis include slow carotid artery upstroke, reduced carotid artery volume, maximal murmur intensity at the second right intercostal space, and reduced intensity of the second heart sound. On the other hand, the absence of a murmur over the right clavicle can help rule out the condition (JAMA. 1997;277:564-571; J Gen Intern Med. 1998;13:699-704).
Treatment for mild cases is symptomatic. Intense physical activity should be limited. More severe cases require surgical repair. A minority of cases will present with acquired von Willebrand disease that benefits from aortic valve replacement.
