title: Exercise stress testing in asymptomatic severe aortic stenosis.
abstract: Aortic valve replacement is the accepted therapy for patients with severe symptomatic aortic stenosis (AS). However, the timing of surgery in asymptomatic patients is less well defined, as some -- but not all -- asymptomatic patients are at increased risk. Exercise stress testing is an attractive means to assess risk in such patients, as it is readily available, standardized, physiological, and presents a controlled environment in which to assess whether patients truly are asymptomatic. This review summarizes existing literature and current guideline recommendations addressing exercise testing in asymptomatic patients with AS, and provides a recommendation for its use in a subset of patients.
