Stress echocardiography in aortic stenosis

Journal of Clinical and Preventive Cardiology, 2019
In apparently asymptomatic severe aortic stenosis (AS) group, stress echocardiography objectively identifies symptomatic, high-risk AS patients requiring early aortic valve replacement (AVR).

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).

Aortic pulse wave velocity and its relationship with transaortic flow and gradients in patients with severe aortic stenosis undergoing aortic valve replacement

Indian Heart Journal, 2020
Background: Low-flow, low-gradient severe aortic stenosis (LFLGAS) is a common clinical entity and is associated with poor prognosis. Increased left ventricular (LV) afterload is one of the mechanisms contributing to low LV stroke volume index (SVi) in ...

Protected complex percutaneous coronary intervention and transcatheter aortic valve replacement using extracorporeal membrane oxygenation in a high-risk frail patient: a case report

Journal of Medical Case Reports, 2020
Background Transcatheter aortic valve replacement has become a routine procedure for patients with severe symptomatic aortic stenosis at increased surgical risk. Not much is known about using prophylactic support with venoarterial extracorporeal membrane

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

Predictors of Mortality and Symptomatic Outcome of Patients With Low‐Flow Severe Aortic Stenosis Undergoing Transcatheter Aortic Valve Replacement

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
BackgroundImpaired left ventricular (LV) ejection fraction is a common finding in patients with aortic stenosis and serves as a predictor of morbidity and mortality after transcatheter aortic valve replacement.

Management of low-gradient aortic stenosis [PDF]

Cor et Vasa, 2017
U nezanedbatelne casti nemocných s významnou aortalni stenozou je prokazan nizký transvalvularni aortalni gradient. V klinicke praxi rozeznavame tři hlavni subtypy aortalni stenozy s nizkým gradientem: 1. klasický typ s nizkou ejekcni frakci leve komory, 2. paradoxni typ se zachovanou ejekcni frakci leve komory a 3.

Low “gradient”, low flow aortic stenosis [PDF]

Heart, 2006
Aortic stenosis is thought to have a long, asymptomatic latent phase during which the risk of sudden death is low. In fact symptoms can be revealed by treadmill exercise in a large proportion of apparently asymptomatic patients.1 Patients may limit exercise to avoid symptoms or may fail to recognise the presence of exertional breathlessness or ascribe ...
