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.

Surgical aortic valve replacement for low-gradient aortic stenosis

Journal of Cardiovascular Medicine, 2022
Low-gradient aortic stenosis is a challenging entity that needs accurate preoperative evaluation. For this high-risk patient population, ad hoc predictive scores are not available and profile risk is currently revealed by the EuroSCOREs.

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

Dilemma in the therapeutic management of low-gradient aortic stenosis

Current Opinion in Cardiology, 2017
Purpose of review : Grading of aortic stenosis is essential in aortic stenosis management patients. However, despite clear thresholds provided in the guidelines, up to 30% of patients have discordant grading of aortic stenosis. The management of patients

Imaging of Low-Gradient Severe Aortic Stenosis [PDF]

JACC: Cardiovascular Imaging, 2013
Although most patients with severe aortic stenosis (AS) have high peak velocity and mean transvalvular gradient, there is a subset of patients with low-flow, low-gradient severe AS (LGSAS).

Comprehensive assessment of the aortic valve in critically ill patients for the non-cardiologist. Part I: Aortic stenosis of the native valve

Anaesthesiology Intensive Therapy, 2021
Aortic stenosis (AS) causes left ventricular outflow obstruction. Severe AS has major haemodynamic implications in critically ill patients, in whom increased cardiac output and oxygen delivery are often required.

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.

Dobutamine Stress Echocardiography in Low-Gradient Aortic Stenosis [PDF]

European Heart Journal, 2023
Abstract Background Dobutamine stress echocardiography (DSE) is recommended by guidelines to distinguish between true-severe and pseudo-severe aortic stenosis (AS) in patients with low-gradients and left ventricular ejection fraction (LVEF) <50%.
