Aortic Stenosis and Cardiac Amyloidosis: JACC Review Topic of the Week.

Journal of the American College of Cardiology, 2019
The prevalence of calcific aortic stenosis (AS) and of cardiac amyloidosis (CA) increases with age, and their association is not uncommon in the elderly.

Computational Modeling Meets 3D Bioprinting: Emerging Synergies in Cardiovascular Disease Modeling

Advanced Healthcare Materials, EarlyView.
Emerging advances in three‐dimensional bioprinting and computational modeling are reshaping cardiovascular (CV) research by enabling more realistic, patient‐specific tissue platforms. This review surveys cutting‐edge approaches that merge biomimetic CV constructs with computational simulations to overcome the limitations of traditional models, improve ...

Successful percutaneous balloon dilatation of supravalvular aortic membrane

Heart Views, 2019
Supravalvular aortic stenosis is the least common type of left ventricular outflow tract obstruction. Primary balloon dilatation of membranous supravalvular aortic stenosis was performed in a 10-year-old male child with a remarkable reduction in systolic

Lipoprotein(a) and Oxidized Phospholipids Promote Valve Calcification in Patients With Aortic Stenosis

Journal of the American College of Cardiology, 2019
Background Lipoprotein(a) [Lp(a)], a major carrier of oxidized phospholipids (OxPL), is associated with an increased incidence of aortic stenosis (AS).

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 ...

Monocyte subsets, stanford-A acute aortic dissection, and carotid srtery stenosis. new evidences [PDF]

, 2019
Monocytes are a heterogeneous cell population distinguished into three subsets with distinctive phenotypic and functional properties: "classical" (CD14++CD16-), "intermediate" (CD14++CD16+), and "nonclassical" (CD14+CD16++).

Supravalvular Aortic Stenosis [PDF]

Circulation, 1958
A case of supravalvular aortic stenosis is described. The diagnosis was suspected from pressure curves obtained at retrograde catheterization of the left ventricle. At operation a circular narrowing of the aorta 2 cm. above the valvular ring was seen. No attempt at surgical correction was made; the patient died at the end of the operation.

Imaging and Impact of Myocardial Fibrosis in Aortic Stenosis

JACC Cardiovascular Imaging, 2019
Aortic stenosis is characterized both by progressive valve narrowing and the left ventricular remodeling response that ensues. The only effective treatment is aortic valve replacement, which is usually recommended in patients with severe stenosis and ...

Elastomeric Micro‐Balloons for Remote Control of Cerebral Blood Flow and Real‐Time In vivo Imaging of Rodent Brain Response to Hypoperfusion

Advanced Materials, EarlyView.
This study reports the fabrication of MRI‐compatible elastomeric micro‐balloons via a multi‐step bubble casting process, where the monolithic elastomeric wall is selectively stiffened for reversible and controlled inflation and elasticity, depending on the target vessels for graded occlusion of cerebral arteries.

Galectin-3 as a novel biotarget in cardiovascular alterations associated to development of severe aortic stenosis

Anales del Sistema Sanitario de Navarra, 2019
Aortic stenosis is one of the most common heart valve diseases, as well as one of the most common causes of heart failure in the elderly. Currently, there are no medical therapies to prevent or slow the progression of the disease.
