Low flow low gradient aortic stenosis: clinical pathways [PDF]

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.

Transcatheter aortic valve implantation outcomes in patients with low flow low gradient aortic stenosis

Revista Portuguesa de Cardiologia, 2022
Background: Some studies suggest that patients with low flow low gradient (LF-LG) aortic stenosis (AS) may achieve worse results after undergoing transcatheter aortic valve implantation (TAVI).

Low-Gradient, Low Ejection Fraction Severe Aortic Stenosis: Still a Management Conundrum

Cardiovascular Innovations and Applications, 2018
The management of patients with severe symptomatic aortic stenosis and a high transvalvular gradient is straightforward. It requires aortic valve replacement. Management of aortic stenosis patients with low flow, low ejection fraction and low gradient is

Low-Flow, Low-Gradient, Normal Ejection Fraction Aortic Stenosis

Current Cardiology Reports, 2010
A substantial proportion of patients with severe aortic stenosis may paradoxically have low transvalvular flow and a low gradient, despite the presence of normal left ventricular (LV) ejection fraction. These patients are characterized by pronounced LV concentric remodeling with small LV cavity size, impaired LV filling, altered myocardial function ...

Cellular and extracellular proteomic profiling of paradoxical low-flow low-gradient aortic stenosis myocardium [PDF]

Frontiers in Cardiovascular Medicine
AimsPatients with severe aortic stenosis (AS), low transvalvular flow (LF) and low gradient (LG) with normal ejection fraction (EF)—are referred to as paradoxical LF-LG AS (PLF-LG).

Right Ventricular and Pulmonary Computed Tomography Assessments in Paradoxical Low-Flow Low-Gradient Aortic Stenosis Undergoing Transcatheter Aortic Valve Replacement [PDF]

Structural Heart, 2022
Background: Patients with paradoxical low-flow low-gradient aortic stenosis (pLFLG AS) have high mortality and a high degree of transcatheter aortic valve replacement (TAVR) futility.

Low-Flow, Low-Gradient Aortic Stenosis in Transthyretin Cardiac Amyloidosis: Diagnostic and Therapeutic Challenges—A Case Report [PDF]

Diagnostics
Background: In low-flow, low-gradient aortic stenosis (LFLG AS), restricted aortic valve opening may represent either fixed valvular obstruction or flow-dependent incomplete leaflet opening due to reduced forward flow.

Development of paradoxical low-flow, low-gradient severe aortic stenosis

Heart, 2015
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 that LFLG-sAS represents an end-stage point of sAS, but longitudinal information has not been described.
