Comparison of Early Surgical or Transcatheter Aortic Valve Replacement Versus Conservative Management in Low‐Flow, Low‐Gradient Aortic Stenosis Using Inverse Probability of Treatment Weighting: Results From the TOPAS Prospective Observational Cohort Study [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background No randomized comparison of early (ie, ≤3 months) aortic valve replacement (AVR) versus conservative management or of transcatheter AVR (TAVR) versus surgical AVR has been conducted in patients with low‐flow, low‐gradient (LFLG) aortic ...

Passive Leg Raise Stress Echocardiography in Severe Paradoxical Low-Flow, Low-Gradient Aortic Stenosis. [PDF]

, 2022
BACKGROUND Dobutamine stress echocardiography is used to increase transvalvular flow in patients with low-flow, low-gradient aortic stenosis (AS). Dobutamine fails to increase the stroke volume index (SVI) in one third of patients.

Low-Flow/Low-Gradient Aortic Stenosis [PDF]

Circulation, 2011
Aortic stenosis (AS) is 1 of the most common valve disorders encountered in clinical practice and 1 of the most frequent indications for valve replacement surgery. Decades of research and clinical experience have resulted in the development of guidelines that provide the clinician with an evidence-based approach to the management of patients with ...

True-severe Stenosis 1 in Paradoxical Low-flow Low-gradient Aortic Stenosis: Outcomes after Transcatheter Aortic Valve Replacement. [PDF]

, 2021
AIMS The ESC/EACTS guidelines propose criteria that determine the likelihood of true-severe aortic stenosis (AS). We aimed to investigate the impact of the guideline-based criteria of the likelihood of true-severe AS in patients with low-flow low ...

Low-flow, Low-gradient Severe Aortic Stenosis: A Review

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

Low-Flow Low-Gradient Aortic Stenosis [PDF]

Circulation: Cardiovascular Imaging, 2012
Aortic stenosis (AS) remains a common and important clinical entity and, when severe, is associated with significant morbidity and mortality. Fortunately, definitive surgical therapies have been developed that have significantly altered the natural history of this disease. The clinical challenge is to accurately assess AS severity and identify patients

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 ...
