Aortic stenosis is a common, potentially fatal condition that is set to become an increasing
public health burden. Once symptoms develop, there is an inexorable deterioration with a …

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: 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 …

2 Chin et al Novel Imaging in Aortic Stenosis aortic stenosis. 19 Unfortunately, this 4-point
score remains semiquantitative and limited by poor interobserver agreement …

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 Aortic valve stenosis (AS) is a progressive disease, but the impact of baseline
AS haemodynamic or anatomic severity on AS progression remains unclear. Methods In 149 …

Objective Among patients with severe aortic stenosis (sAS) and preserved LVEF, those with
low-flow, low-gradient sAS (LFLG-sAS) have an adverse prognosis. It has been proposed …

In 2007, we reported that a substantial proportion of patients with severe aortic stenosis may
have a low flow (LF)(ie, reduced stroke volume), and thus, often have a low transvalvular …

Background Whether the prognosis of paradoxical low-gradient severe aortic stenosis (PLG-
SAS), especially due to paradoxical low-flow low-gradient SAS (PLFLG-SAS), is malignant …

Opinion statement Aortic valve stenosis is characterized by indolent progression followed by
the late development of symptoms once left ventricular compensatory mechanisms fail. In …
