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).

Balloon‐Expandable Versus Self‐Expanding Prostheses for Transcatheter Treatment of Patients With Low‐Flow, Low‐Gradient Aortic Stenosis [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background The use of balloon‐expandable valves (BEVs) or self‐expanding valves (SEVs) for transcatheter aortic valve replacement (TAVR) in patients with low‐flow, low‐gradient aortic stenosis (LFLG‐AS) has been poorly investigated.

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 ...

Long‐Term Outcomes of Transcatheter Aortic Valve Replacement in Low‐Flow Low‐Gradient Aortic Stenosis: A Reconstructed Time‐to‐Event and Multivariate Meta‐Analysis [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background There are uncertainties regarding long‐term outcomes of low‐flow, low‐gradient (LFLG) severe aortic stenosis (AS) following transcatheter aortic valve replacement (TAVR). This study investigates long‐term outcomes of TAVR for high‐gradient (HG)

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).

Outcomes and Predictors of Flow Improvement After Transcatheter Aortic Valve Replacement in Patients With Low-Flow Low-Gradient Aortic Stenosis [PDF]

Structural Heart
Background: Flow is known to typically improve after transcatheter aortic valve replacement (TAVR); however, the characteristics correlating with improvement are still unclear.
