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 …

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 …

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 …

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: 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 …

Background—Up to 30% of patients with severe aortic stenosis (SAS; indexed aortic valve
area< 0.6 cm2/m2) present with low transvalvular gradient despite a normal left ventricular …

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—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 …

Background—Among patients with severe aortic stenosis (AS) and preserved ejection
fraction, those with low gradient (LG) and reduced stroke volume may have an adverse …

Aims Low gradient severe aortic stenosis (AS) with preserved left ventricular ejection fraction
(LVEF) may be attributed to aortic valve area index (AVAi) underestimation due to the …
