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 ...

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.

Echocardiographic predictors of survival in low gradient aortic stenosis

The American Journal of Cardiology, 2000
Echocardiographic predictors of long-term survival for patients with low gradient aortic stenosis who undergo aortic valve replacement have not been previously reported. This study shows that patients with larger pre- and postoperative left ventricular volumes, a lower mean preoperative aortic pressure gradient, and failure of volumes to decrease and ...

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 ...

[Paradoxical low-flow low-gradient aortic stenosis].

Der Internist, 2016
In approximately one third of patients presenting with suspected severe aortic stenosis, there is a discrepancy between a severely reduced aortic valve opening area (
