Multimodality Imaging for Discordant Low-Gradient Aortic Stenosis: Assessing the Valve and the Myocardium [PDF]

Frontiers in Cardiovascular Medicine, 2020
Aortic stenosis (AS) is a disease of the valve and the myocardium. A correct assessment of the valve disease severity is key to define the need for aortic valve replacement (AVR), but a better understanding of the myocardial consequences of the increased

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.

Reclassification of aortic stenosis by fusion of echocardiography and computed tomography in low-gradient aortic stenosis. [PDF]

Neth Heart J, 2022
Abstract Background The integration of computed tomography (CT)-derived left ventricular outflow tract area into the echocardiography-derived continuity equation results in the reclassification of a significant proportion of patients with severe aortic stenosis (AS) into moderate AS based on aortic valve area indexed to ...

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 ...

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.

Dobutamine Stress Echocardiography in Low-Gradient Aortic Stenosis

European Heart Journal, 2023
Abstract Background Dobutamine 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%.

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).
