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).

Catheter-Induced Postextrasystolic Potentiation in the Assessment of Severity of Low-Gradient Aortic Valve Stenosis

Circulation. Cardiovascular Interventions, 2023
Background: Deciphering which patients with low-gradient aortic valve disease have severe stenosis can be difficult. We aimed to correlate the postextrasystolic potentiation (PESP) with dobutamine stress echocardiography and multidetector computed ...

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 ...

Low flow low gradient aortic stenosis: clinical pathways

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.

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

Possible predicative role of electrical risk score on transcatheter aortic valve replacement outcomes in older patients. preliminary data [PDF]

, 2018
Background:Transcatheter aortic valve replacement (TAVR) is an effective procedure capable to change the natural history of the degenerative aortic valve stenosis.

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.
