Transcatheter aortic-valve replacement for inoperable severe aortic stenosis. [PDF]

, 2012
BACKGROUND: Transcatheter aortic-valve replacement (TAVR) is the recommended therapy for patients with severe aortic stenosis who are not suitable candidates for surgery. The outcomes beyond 1 year in such patients are not known.

Reclassification of aortic stenosis by fusion of echocardiography and computed tomography in low-gradient aortic stenosis [PDF]

Netherlands Heart Journal, 2020
Abstract Background The integration of computed tomography (CT)-derived left ventricular outflow tract area into the echocardiography-derived continuity equation results in the reclassification of a significant proportion of patients with severe aortic stenosis (AS) into moderate AS based on aortic valve area indexed to ...

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.

Pseudo-discordance mimicking low-flow low-gradient aortic stenosis in transcatheter aortic valve replacement patients with severe symptomatic aortic stenosis

Cardiology Journal, 2023
BACKGROUND: While the combination of a small aortic valve area (AVA) and low mean gradient is frequently labeled ‘low-flow low-gradient aortic stenosis (AS)’, there are two potential causes for this finding: underestimation of mean gradient and ...

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 ...

Investigation of physiological pulsatile flow in a model arterial stenosis using large-eddy and direct numerical simulations [PDF]

, 2012
Physiologicalpulsatileflow in a 3D model of arterialstenosis is investigated by using largeeddysimulation (LES) technique. The computational domain chosen is a simple channel with a biological type stenosis formed eccentrically on the top wall.

Post-stenotic aortic dilatation. [PDF]

, 2006
Aortic stenosis is the most common valvular heart disease affecting up to 4% of the elderly population. It can be associated with dilatation of the ascending aorta and subsequent dissection.

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.

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
