Clinical outcomes of bicuspid versus tricuspid aortic valve stenosis after transcatheter aortic valve replacement with self-expandable valves

BMC Cardiovascular Disorders, 2022
Background There is a lack of available data on specific prognostic comparisons between transcatheter aortic valve replacement (TAVR) using self-expandable valves (SEV) in patients with stenotic Type 0, Type 1 bicuspid aortic valve (BAV) and tricuspid ...

How to use the aortic valve calcium score to improve the results of transcatheter aortic valve implantation with a self-expanding prosthesis

Archives of Cardiovascular Diseases, 2022
In recent years, transcatheter aortic valve implantation (TAVI) without predilation (direct TAVI) has become the preferred method for implanting TAVI prostheses. Appropriate patient selection is important to avoid suboptimal outcomes and associated complications.To evaluate whether aortic valve calcification measured with computed tomography predicts ...

Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

Advanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

A study on the prevalence, distribution and related factors of heart valve calcification using coronary CT angiography

International Journal of Cardiology: Heart & Vasculature, 2020
Background: The concept of active atherosclerotic disease has been accepted for heart valve calcification (HVC). We investigated prevalence, distribution and related factors of HVC in patients who had undergone coronary CT angiography (CCTA).

Assessment of Calcium Score Cutoff Point for Clinically Significant Aortic Stenosis on Lung Cancer Screening Program Low-Dose Computed Tomography—A Cross-Sectional Analysis

Diagnostics, 2023
Low-dose computed tomography (LDCT) is predominantly applied in lung cancer screening programs. Tobacco smoking is the main risk factor for developing lung cancer but is also common for cardiovascular diseases, including aortic stenosis (AS ...

Prediction of aortic valve calcium score in echocardiography through AI [PDF]

Eur Heart J Digit Health
Abstract Background A key mechanism and major predictor in the progression of aortic stenosis (AS) is the aortic valve calcification (AVC). Computed tomography (CT) aortic valve Agatston calcium score (AVCS) remains the gold standard for quantifying AVC.

Insulin resistance and subclinical abnormalities of global and regional left ventricular function in patients with aortic valve sclerosis [PDF]

, 2014
BACKGROUND: Insulin resistance, as a key mediator of metabolic syndrome, is thought to be associated with pathogenesis of calcific aortic valve disease and altered left ventricular (LV) function and structure.

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

Advanced Healthcare Materials, EarlyView.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...
