The evolving approach to the evaluation of low-gradient aortic stenosis

Cardiovascular Revascularization Medicine, 2019
Severe aortic stenosis (AS) is typically identified by a low valve area (≤1.0 cm2) and high mean gradient (≥40 mm Hg). A subset of patients are found to have a less than severe mean gradient (

Prognostic value of transvalvular flow rate in patients with low‐gradient severe aortic stenosis: A dobutamine stress echocardiography study

Echocardiography, 2023
There are limited data on the clinical relevance of transvalvular flow rate (Qmean) at rest (Qrest) and at peak stress (Qstress) during dobutamine stress echocardiography (DSE) in patients with low‐gradient severe aortic stenosis (LG‐SAS).

Low gradient aortic stenosis: Assessment, treatment, and outcome

Catheterization and Cardiovascular Interventions, 2008
AbstractAortic stenosis is a commonly encountered valvular disorder in the treatment of cardiovascular disease. Generally, symptomatic patients who undergo valve replacement experience a vast reduction in symptoms and a great improvement in survival. A subset of symptomatic patients in whom management is less clear are those with a small transvalvular ...

True-severe Stenosis 1 in Paradoxical Low-flow Low-gradient Aortic Stenosis: Outcomes after Transcatheter Aortic Valve Replacement.

European Heart Journal - Quality of Care and Clinical Outcomes, 2021
AIMS The ESC/EACTS guidelines propose criteria that determine the likelihood of true-severe aortic stenosis (AS). We aimed to investigate the impact of the guideline-based criteria of the likelihood of true-severe AS in patients with low-flow low ...

Low Gradient Aortic Stenosis: Role of Echocardiography

Current Cardiovascular Imaging Reports, 2019
The purpose of this paper is to review the current role of echocardiography in the evaluation of patients with low gradient severe aortic stenosis (LG severe AS). Discordant grading of AS severity, in which a small aortic valve area coexists with a small gradient, can result in diagnostic and therapeutic dilemmas.

Diagnosis and management of low-flow, low-gradient aortic stenosis

Current Opinion in Cardiology, 2020
Purpose of review The severity of low-flow, low-gradient aortic stenosis cases continue to be misunderstood because of challenging diagnosis, and treatment remains complex. We discuss current diagnostic and treatment modalities for low-flow, low-gradient aortic stenosis. Recent findings

Low gradient, low ejection fraction aortic stenosis

Current Treatment Options in Cardiovascular Medicine, 2003
Low gradient aortic stenosis can be caused by critical aortic stenosis causing left ventricular impairment or by more moderate aortic stenosis coexisting with another cause of left ventricular impairment. The main challenges are to differentiate these two states and then to determine whether the left ventricle is likely to recover after aortic valve ...
