low flow low gradient aortic stenosis diagnosis

Low-flowlow-gradient LFLG AS with low ejection fraction is defined as a combination of aortic valve area AVA gradient. N 2007 we reported that a substantial proportion of patients with severe aortic stenosis may have alowﬂow lf ie reduced stroke volume and thus often have a low transvalvular pressure.
