Low-Gradient aortic stenosis; the diagnostic dilemma

Heart Views, 2022
Low-gradient (LG) aortic valve stenosis (AS) constitutes a significant subset among patients with severe aortic stenosis. This entity represents one of the most challenging heart conditions when it comes to diagnosis and management, mainly because of the

Clinical Outcomes in High‐Gradient, Classical Low‐Flow, Low‐Gradient, and Paradoxical Low‐Flow, Low‐Gradient Aortic Stenosis After Transcatheter Aortic Valve Implantation: A Report From the SwissTAVI Registry [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background In view of the rising global burden of severe symptomatic aortic stenosis, its early recognition and treatment is key. Although patients with classical low‐flow, low‐gradient (C‐LFLG) aortic stenosis have higher rates of death after ...

Prognostic Impact of Mitral Regurgitation Before and After Transcatheter Aortic Valve Replacement in Patients With Severe Low‐Flow, Low‐Gradient Aortic Stenosis [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background There is little evidence about the prognostic role of mitral regurgitation (MR) in patients with low‐flow, low‐gradient aortic stenosis undergoing transcatheter aortic valve replacement (TAVR).

Risk prediction in patients with classical low-flow, low-gradient aortic stenosis undergoing surgical intervention [PDF]

Frontiers in Cardiovascular Medicine, 2023
IntroductionClassical low-flow, low-gradient aortic stenosis (LFLG-AS) is an advanced stage of aortic stenosis, which has a poor prognosis with medical treatment and a high operative mortality after surgical aortic valve replacement (SAVR).

Pseudo-discordance mimicking low-flow low-gradient aortic stenosis in transcatheter aortic valve replacement patients with severe symptomatic aortic stenosis [PDF]

Cardiology Journal, 2023
BACKGROUND: While the combination of a small aortic valve area (AVA) and low mean gradient is frequently labeled ‘low-flow low-gradient aortic stenosis (AS)’, there are two potential causes for this finding: underestimation of mean gradient and ...

Outcomes and Predictors of Flow Improvement After Transcatheter Aortic Valve Replacement in Patients With Low-Flow Low-Gradient Aortic Stenosis [PDF]

Structural Heart
Background: Flow is known to typically improve after transcatheter aortic valve replacement (TAVR); however, the characteristics correlating with improvement are still unclear.

Low flow low gradient aortic stenosis: clinical pathways

Indian Heart Journal, 2014
Aortic stenosis patients with severe LV dysfunction and low cardiac output present with relatively low transvalvular gradients. It is difficult to distinguish them from aortic sclerosis and LV dysfunction with low cardiac output.

A Novel Echocardiographic Parameter to Confirm Low-Gradient Aortic Stenosis Severity [PDF]

JACC: Advances
Background: In patients with low-gradient (LG) aortic stenosis (AS), confirming disease severity and indication of intervention often requires dobutamine stress echocardiography (DSE) or aortic valve calcium scoring by computed tomography.
