Estimation of Aortic Valve Calcium Score Based on Angiographic Phase Versus Reduction of Ionizing Radiation Dose in Computed Tomography [PDF]

Life, 2021
The aim of the study was to evaluate the estimation efficacy of aortic valve calcium score (AVCS) based on the multislice computed tomography (MSCT) angiographic phase. The evaluation of the reduced amount of ionizing radiation dose was performed because

Aortic Valve Calcium Score Is Associated With Acute Stroke in Transcatheter Aortic Valve Replacement Patients [PDF]

Journal of the Society for Cardiovascular Angiography & Interventions, 2022
Transcatheter aortic valve replacement (TAVR) is the treatment of choice for patients with severe aortic stenosis who are at a moderate or higher surgical risk. Stroke is a recognised and serious complication of TAVR, and it is important to identify patients at higher stroke risk.

Diagnostic role of aortic valve calcium scoring in various etiologies of aortic stenosis [PDF]

Scientific Reports, 2023
Most of the studies about aortic valve calcium (AVC) score in aortic stenosis (AS) were based on degenerative or bicuspid AS but not rheumatic AS. We aimed to study the diagnostic accuracy of AVC score to determine severe AS in various etiologies.

Opportunistic automated aortic valve calcification assessment in low-cost, screening CT calcium score exams [PDF]

Scientific Reports
Aortic valve stenosis (AS) is the most common valvular disease, with a growing impact in the aging population. AS can culminate in heart failure if left untreated.

Aortic Valve Calcium Score Spectrum Identifies Bimodal Outcomes for Transcatheter Aortic Valve Implantation: Insights From the AMTRAC Registry [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Degenerative calcification is the primary mechanism underlying severe aortic stenosis; however, some patients with hemodynamically severe aortic stenosis have low aortic valve calcium scores (AVCS), suggesting heterogeneous disease processes ...

Aortic Valve Calcium Scoring Using True and Virtual Non-Contrast Reconstructions on Photon-Counting CT with Differing Slice Increments: Impact on Calcium Severity Classifications [PDF]

Tomography
Background/Objectives: Aortic valve calcification is commonly evaluated using 3.0 mm true non-contrast (TNC) computed tomography (CT) images. This study evaluates the reproducibility of virtual non-contrast (VNC) reconstructions at different slice ...

Aortic valve calcium score in prediction of post-TAVI complications in an Egyptian cohort [PDF]

The Egyptian Journal of Radiology and Nuclear Medicine, 2022
Background Severe symptomatic aortic stenosis is a common disorder in the elderly and is associated with high morbidity and mortality rate. Traditionally, surgical aortic valve replacement has been considered the most effective treatment for advanced ...
