Abstract: Objectives : The aim of this case match study was to compare the outcome of patients with paradoxical low-flow (left ventricular ejection fraction [LVEF] =50% but stroke volume index <35 ml/m2), low-gradient (mean gradient [MG] <40 mm Hg), a priori severe (aortic valve area [AVA] =1.0 cm2) aortic stenosis (AS) (PLG-SAS group) with that of patients with a severe AS (AVA =1.0 cm2) and consistent high-gradient (MG =40 mm Hg) (HG-SAS group) and with that of patients with a moderate AS (AVA >1.0 cm2 and MG <40 mm Hg) (MAS group).
