TAVI in patients with low-flow low-gradient aortic stenosis-short-term and long-term outcomes. [PDF]

Clin Res Cardiol, 2022
The study objective was to characterize different groups of low-flow low-gradient (LFLG) aortic stenosis (AS) and determine short-term outcomes and long-term mortality according to Valve Academic Research Consortium-3 (VARC-3) endpoint definitions ...

Cellular and extracellular proteomic profiling of paradoxical low-flow low-gradient aortic stenosis myocardium. [PDF]

Front Cardiovasc Med
Aims Patients with severe aortic stenosis (AS), low transvalvular flow (LF) and low gradient (LG) with normal ejection fraction (EF)—are referred to as paradoxical LF-LG AS (PLF-LG). PLF-LG patients develop more advanced heart failure symptoms and have a

Right ventricular dysfunction and impaired right ventricular-pulmonary arterial coupling in paradoxical low-flow, low-gradient aortic stenosis. [PDF]

Eur J Heart Fail
Paradoxical low‐flow, low‐gradient aortic stenosis (pLFLG AS) may represent a diagnostic challenge, and its pathophysiology is complex. While left ventricular (LV) systolic function is preserved, right ventricular dysfunction (RVD) and consecutive LV ...

Left Ventricle Biomechanics of Low-Flow, Low-Gradient Aortic Stenosis: A Patient-Specific Computational Model. [PDF]

Front Physiol, 2022
This study aimed to create an imaging-derived patient-specific computational model of low-flow, low-gradient (LFLG) aortic stenosis (AS) to obtain biomechanics data about the left ventricle.

Prognostic and therapeutic implications of a low aortic valve calcium score in patients with low-gradient aortic stenosis. [PDF]

Eur Heart J Cardiovasc Imaging
Aims Low-gradient (LG) aortic stenosis (AS) poses a diagnostic challenge. Aortic valve calcium score (AVCS) assessment has emerged as a complementary diagnostic method when echocardiography provides discordant results.

Risk prediction in patients with low-flow, low-gradient aortic stenosis and reduced ejection fraction undergoing TAVI. [PDF]

Open Heart, 2022
Objective Patients with low-flow, low-gradient aortic stenosis (LFLG AS) and reduced left ventricular ejection fraction (LVEF) are known to suffer from poor prognosis after transcatheter aortic valve implantation (TAVI).

Early and mid-term outcome of patients with low-flow-low-gradient aortic stenosis treated with newer-generation transcatheter aortic valves. [PDF]

Front Cardiovasc Med, 2022
Patients with non-paradoxical low-flow–low-gradient (LFLG) aortic stenosis (AS) are at increased surgical risk, and thus, they may particularly benefit from transcatheter aortic valve replacement (TAVR).

Front Cardiovasc Med, 2022
Objectives To determine the risk of mortality and need for aortic valve replacement (AVR) in patients with low-flow low-gradient (LFLG) aortic stenosis (AS).

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.

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

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 ...
