Aortic valve calcium volume as measured by native versus contrast-enhanced computer tomography and the implications for the diagnosis of severe aortic stenosis in TAVR patients with low-gradient aortic stenosis. [PDF]

Egypt Heart J, 2022
Most of TAVR centers evaluate the calcium score in contrast-enhanced (ce) CT. We compared in this study between different methodologies to measure calcium score. We studied also the difference between patients with low-gradient (LG) and high-gradient (HG)

Low-flow, Low-gradient Severe Aortic Stenosis: A Review [PDF]

Heart International, 2023
Aortic stenosis (AS) is a common valve pathology experienced by patients worldwide. There are limited population-based studies assessing its prevalence; however, epidemiological studies emphasize that the burden of disease is growing. Recognizing AS relies on accurate clinical assessment and diagnostic investigations. Patients who develop severe AS are

Concomitant mitral regurgitation in patients with low-gradient aortic stenosis: an analysis from the German Aortic Valve Registry. [PDF]

Clin Res Cardiol, 2022
Patients with severe aortic stenosis (AS) frequently presented mitral regurgitation (MR), which may interfere with the standard echocardiographic measurements of mean pressure gradient (MPG), flow velocity, and aortic valve area (AVA).

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.

A Novel Echocardiographic Parameter to Confirm Low-Gradient Aortic Stenosis Severity [PDF]

JACC: Advances
Background: In patients with low-gradient (LG) aortic stenosis (AS), confirming disease severity and indication of intervention often requires dobutamine stress echocardiography (DSE) or aortic valve calcium scoring by computed tomography.

How to deal with low-flow low-gradient aortic stenosis and reduced left ventricle ejection fraction: from literature review to tips for clinical practice. [PDF]

Heart Fail Rev, 2022
Low-flow low-gradient aortic stenosis (LFLG AS) with reduced left ventricle ejection fraction (LVEF) is still a diagnostic and therapeutic challenge. The aim of this paper is to review the latest evidences about the assessment of the valvular disease ...

P289 Aortic valve resistance risk-stratifies low-gradient aortic stenosis [PDF]

European Heart Journal - Cardiovascular Imaging, 2020
Abstract Background Grading the severity of aortic stenosis (AS) is challenging, since there is a discrepancy between aortic valve area (AVA) and mean pressure gradient (mPG). Arotic valve resistance (RES) has been proposed as a usuful descriptor of AS severity, but it is not commonly used for ...
