Significance and distribution of aortic valve calcium score before TAVI [PDF]

European Heart Journal, 2022
Abstract Introduction Aortic valve calcium scoring by multislice computed tomography (MSCT) is an alternative load independent assessment of aortic stenosis severity. Recent studies have further demonstrated that aortic valve calcification load is related to adverse outcomes during and after ...

Artificial intelligence for aortic valve calcium score quantification by echocardiography [PDF]

Abstract Background Aortic valve calcification (AVC), as measured by gold-standard computed tomography (CT) Agatston score, provides an anatomic assessment of aortic stenosis (AS) severity and is a key predictor of AS progression and need for valve replacement.

Cholesterol efflux promoting function of high-density lipoproteins in calcific aortic valve stenosis

Atherosclerosis Plus, 2021
Background and aims: Cholesterol efflux capacity is a functional property of high-density lipoproteins (HDL) reflecting the efficiency of the atheroprotective reverse cholesterol transport process in humans.

Computed Tomography Aortic Valve Calcium Scoring in Patients With Aortic Stenosis [PDF]

Circulation: Cardiovascular Imaging, 2018
Background— Computed tomography aortic valve calcium scoring (CT-AVC) holds promise for the assessment of patients with aortic stenosis (AS). We sought to establish the clinical utility of CT-AVC in an international multicenter cohort of patients. Methods and Results—

Calcium Load in the Aortic Valve, Aortic Root, and Left Ventricular Outflow Tract and the Risk for a Periprocedural Stroke

Structural Heart, 2022
Background: Periprocedural stroke during transcatheter aortic valve implantation is a rare but devastating complication. The calcified aortic valve is the most likely source of the emboli in a periprocedural stroke.

Calcium score of the aortic valve as a predictor of aortic stenosis severity

European Heart Journal - Cardiovascular Imaging, 2021
Abstract Funding Acknowledgements Type of funding sources: None. Background The calcium score of the aortic valve (CaScAoV) is now recommended as a supporting tool to assist in the grading of aortic stenosis (AS) severity when ...

Aortic Valve Calcium Score Is Associated With Coronary Calcified Plaque Burden

International Heart Journal, 2013
The aim of this study was to investigate the association between the aortic valve calcium score (AVCS) and the coronary plaque burden using 64-slice multi-detector computed tomography (MDCT). Calcification of the aortic valve without significant aortic stenosis itself has been suggested to be a marker of atherosclerosis.

Calcium Identification and Scoring Based on Echocardiography. An Exploratory Study on Aortic Valve Stenosis [PDF]

Journal of Personalized Medicine, 2021
Currently, an echocardiography expert is needed to identify calcium in the aortic valve, and a cardiac CT-Scan image is needed for calcium quantification. When performing a CT-scan, the patient is subject to radiation, and therefore the number of CT-scans that can be performed should be limited, restricting the patient’s monitoring.
