Low-Gradient aortic stenosis; the diagnostic dilemma

Heart Views, 2022
Low-gradient (LG) aortic valve stenosis (AS) constitutes a significant subset among patients with severe aortic stenosis. This entity represents one of the most challenging heart conditions when it comes to diagnosis and management, mainly because of the

Risk prediction in patients with classical low-flow, low-gradient aortic stenosis undergoing surgical intervention [PDF]

Frontiers in Cardiovascular Medicine, 2023
IntroductionClassical low-flow, low-gradient aortic stenosis (LFLG-AS) is an advanced stage of aortic stenosis, which has a poor prognosis with medical treatment and a high operative mortality after surgical aortic valve replacement (SAVR).

Clinical Outcomes in High‐Gradient, Classical Low‐Flow, Low‐Gradient, and Paradoxical Low‐Flow, Low‐Gradient Aortic Stenosis After Transcatheter Aortic Valve Implantation: A Report From the SwissTAVI Registry [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background In view of the rising global burden of severe symptomatic aortic stenosis, its early recognition and treatment is key. Although patients with classical low‐flow, low‐gradient (C‐LFLG) aortic stenosis have higher rates of death after ...

Prognostic Impact of Mitral Regurgitation Before and After Transcatheter Aortic Valve Replacement in Patients With Severe Low‐Flow, Low‐Gradient Aortic Stenosis [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background There is little evidence about the prognostic role of mitral regurgitation (MR) in patients with low‐flow, low‐gradient aortic stenosis undergoing transcatheter aortic valve replacement (TAVR).

Multimodality imaging methods and systemic biomarkers in classical low-flow low-gradient aortic stenosis: Key findings for risk stratification. [PDF]

Front Cardiovasc Med, 2023
Objectives The aim of the present study is to assess multimodality imaging findings according to systemic biomarkers, high-sensitivity troponin I (hsTnI) and B-type natriuretic peptide (BNP) levels, in low-flow, low-gradient aortic stenosis (LFLG-AS ...

Dobutamine stress echocardiography in low-gradient aortic stenosis [PDF]

European Heart Journal, 2023
AbstractBackgroundDobutamine 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%. However, DSE has mostly been tested in the setting of LVEF<35% and determination of AS severity has ...

Dobutamine stress echocardiography in paradoxical low-flow, low-gradient aortic stenosis with mitral regurgitation. [PDF]

Eur Heart J Case Rep, 2023
An 86-year-old man was referred to our hospital with heart failure. Transthoracic echocardiography (TTE) demonstrated paradoxical low-flow, low-gradient aortic stenosis (AS) (stroke volume index, 26.2 mL/m 2 ; aortic valve area calculated with the ...
