Timing of Intervention in Aortic Stenosis

P Lancellotti, MA Vannan. Keywords: asymptomatic patients with severe aortic stenosis; treatment timing

ABSTRACT


Current guidelines require that in patients with severe aortic stenosis, symptoms related to the valvular disease be present for consideration of transcatheter aortic-valve replacement (TAVR) or surgical aortic-valve replacement.  In the absence of symptoms, only very severe aortic stenosis is an indication (class IIa) for intervention. Kang et al. now report in the Journal the results of a trial involving patients with asymptomatic, very severe aortic stenosis who were randomly assigned to surgical aortic-valve replacement or conservative care (clinical follow-up and observation). Outcomes (death during or within 30 days after surgery [operative mortality] or death from cardiovascular causes; death from . . .
