RT Journal Article SR Electronic T1 When does asymptomatic aortic stenosis warrant surgery? Assessment techniques JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 271 OP 280 DO 10.3949/ccjm.83a.15069 VO 83 IS 4 A1 Cian P. McCarthy A1 Dermot Phelan A1 Brian Griffin YR 2016 UL http://www.ccjm.org/content/83/4/271.abstract AB Asymptomatic but hemodynamically severe aortic stenosis often poses a dilemma: should the aortic valve be replaced, or is watchful waiting acceptable? Patients with this condition are a diverse group with varying prognoses. Here, we review the guidelines for valve replacement in this situation and highlight the variables useful in establishing which patients should be considered for early intervention even if they have no symptoms.
