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 output, low gradient aortic stenosis [PDF]

Heart, 2003
![Graphic][1] We recently investigated a 47 year old man with increasing dyspnoea of effort (New York Heart Association functional class IV) who had undergone homograft aortic valve replacement seven years previously. At cardiac catheterisation, the epicardial coronary arteries were angiographically normal.

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 ...

Aortic valve chordae tendineae: A rare cause of aortic stenosis

Radiology Case Reports, 2023
We describe a rare case of severe low-flow, low-gradient aortic stenosis due to a calcified aortic valve chordae tendineae. The chordae was captured on cardiac computed tomography (CT) using advanced 3-dimensional image reconstruction to reveal the ...

The Flow Rate in Patients With Low-Gradient Aortic Stenosis. [PDF]

Cureus
 The decision to assess the severity and determine the ideal timing of intervention for low-gradient aortic stenosis poses a greater challenge. Recently, a novel method for determining the flow status of patients with aortic stenosis has been introduced, utilizing flow rate measurements.

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.

Stress echocardiography in aortic stenosis

Journal of Clinical and Preventive Cardiology, 2019
In apparently asymptomatic severe aortic stenosis (AS) group, stress echocardiography objectively identifies symptomatic, high-risk AS patients requiring early aortic valve replacement (AVR).

Transcatheter aortic valve implantation outcomes in patients with low flow low gradient aortic stenosis

Revista Portuguesa de Cardiologia, 2022
Background: Some studies suggest that patients with low flow low gradient (LF-LG) aortic stenosis (AS) may achieve worse results after undergoing transcatheter aortic valve implantation (TAVI).
