Care of patients with apparently asymptomatic severe aortic valve stenosis.

Although most asymptomatic patients with aortic stenosis (AS) have an excellent prognosis with observation only, some patients with severely stenotic aortic valves in the absence of symptoms may benefit from early intervention. In this article, we will review the literature on the use of varied imaging modalities, clinical factors, and biomarker testing to risk stratify such patients. Additionally, we will review the role of medical therapy to modify the course in AS.
