Background The prevalence and outcomes of the different subtypes of severe low‐gradient
aortic stenosis (AS) in routine clinical cardiology practice have not been well characterized …

Background There are currently no established prognostic models for “low-gradient” severe
aortic stenosis (AS), including those with low-flow, low-gradient (LFLG) or normal-flow, low …

Objectives To determine the risk of mortality and need for aortic valve replacement (AVR) in
patients with low-flow low-gradient (LFLG) aortic stenosis (AS). Methods A longitudinal …

Background Normal‐flow, low‐gradient severe aortic stenosis (NF‐LG‐SAS), defined by
aortic valve area< 1 cm2, mean gradient< 40 mm Hg, and indexed stroke volume> 35 …

Background The aim of the present study was to assess and compare the disease
progression of aortic stenosis (AS) subtypes from nonsevere to severe disease on the basis …

The most prevalent form of “low-gradient” aortic stenosis (AS) is characterized by the
concomitant presence of a small aortic valve area (< 1.0 cm2) and a low mean gradient (< …

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 …

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 …

Normal-flow low-gradient severe aortic stenosis (NF-LG-SAS), defined by an aortic valve
area (AVA)< 1 cm², mean pressure gradient (MPG)< 40 mm Hg and indexed stroke …

Surgery of aortic valve stenosis (AS) is often dependent on whether stenosis is considered
severe, as defined by aortic valve area (AVA) and/or mean pressure gradient (dPm) criteria …
