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 …

Background—Recent studies and current clinical observations suggest that some patients
with severe aortic stenosis on the basis of aortic valve area may paradoxically have a …

Aims There is uncertainty in identifying patients with severe aortic stenosis (AS) with
preserved left ventricular (LV) ejection fraction, low flow, and low gradients (LFLG). Prior …

Background: Low mean transvalvular gradient (< 40 mm Hg) and small aortic valve area (<
1.0 cm2) in patients with aortic stenosis (AS) and preserved left ventricular ejection fraction …

Background—Retrospective studies have suggested that patients with a low transvalvular
gradient in the presence of an aortic valve area< 1.0 cm2 and normal ejection fraction may …

An important proportion of patients with aortic stenosis (AS) have a 'low-gradient'AS, ie a
small aortic valve area (AVA< 1.0 cm2) consistent with severe AS but a low mean …

Background—The optimal management of low-gradient “severe” aortic stenosis (mean
gradient< 40 mm Hg, indexed aortic valve area≤ 0.6 cm2/m2) with preserved left ventricular …

Background: Severe low-gradient, low-flow (LG/LF) aortic stenosis with preserved left
ventricular ejection fraction (EF) has been described as a more advanced form of aortic …

Low-flow, low-gradient (LF-LG) aortic stenosis (AS) may occur with depressed or preserved
left ventricular ejection fraction (LVEF), and both situations are among the most challenging …

Objective Low-gradient (LG) severe aortic stenosis (AS) and preserved EF with reduced
stroke volume are associated with an adverse prognosis, but the relationship of stroke …
