ORIGINAL ARTICLE Clinical outcomes in non-surgically managed patients

Objective The management of asymptomatic severe and very severe aortic stenosis (AS) remains unestablished. This study aimed to investigate the clinical outcomes of severe versus very severe AS patients. Design A single centre, retrospective cohort study. Patients and Methods The study retrospectively reviewed 108 conservatively treated patients with severe AS (a maximal jet velocity $4.0 m/s, or mean aortic pressure gradient (MPG) $40 mm Hg, or an aortic valve area (AVA) <1.0 cm2) and 58 patients with very severe AS (a maximal jet velocity $5.0 m/s, or MPG $50 mm Hg or an AVA <0.6 cm2). Clinical outcomes were compared between the two groups, considering the existence of symptoms
