Bicuspid aortic valve associated with aortic thrombotic occlusion

open access: yesThe Egyptian Journal of Internal Medicine, 2016
The bicuspid aortic valve is associated with disorders of the aortic wall, including coarctation of the aorta and aortic dissection. The histologic abnormality underlying aortic complications in bicuspid aortic valve is cystic medial necrosis.

Osteoprotegerin inhibits aortic valve calcification and preserves valve function in hypercholesterolemic mice. [PDF]

open access: yesPLoS ONE, 2013
There are no rigorously confirmed effective medical therapies for calcific aortic stenosis. Hypercholesterolemic Ldlr (-/-) Apob (100/100) mice develop calcific aortic stenosis and valvular cardiomyopathy in old age.

Including Aortic Valve Morphology in Computational Fluid Dynamics Simulations: Initial Findings and Application to Aortic Coarctation [PDF]

open access: yes, 2012
Computational fluid dynamics (CFD) simulations quantifying thoracic aortic flow patterns have not included disturbances from the aortic valve (AoV). 80% of patients with aortic coarctation (CoA) have a bicuspid aortic valve (BAV) which may cause adverse ...

Cell Calcification Models and Their Implications for Medicine and Biomaterial Research

open access: yesAdvanced Healthcare Materials, EarlyView.
Calcification, is the process by which the tissues containing minerals are formed, occurring during normal physiological processes, or in pathological conditions. Here, it is aimed to give a comprehensive overview of the range of cell models available, and the approaches taken by these models, highlighting when and how methodological divergences arise,

Programmable Compliance in Small‐Diameter Vascular Grafts by Design of Melt‐Electrowritten Scaffold Architectures for In Situ Tissue Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
Small‐diameter vascular grafts with compliance tunable by design are fabricated via melt electrowriting. By controlling the winding angle of intertwined helical fibers, grafts with compliances matching those of human vessels, from veins to arteries, are realized. This holds the potential of avoiding a compliance mismatch, which has been identified as a

Redo aortic valve replacement vs valve-in-valve trans-catheter aortic valve implantation: a UK propensity-matched analysis

open access: yesMonaldi Archives for Chest Disease, 2023
This study sought to compare the morbidity and mortality of redo aortic valve replacement (redo-AVR) versus valve-in-valve trans-catheter aortic valve implantation (valve-in-valve TAVI) for patients with a failing bioprosthetic valve.

The Heart of a Horse: 3‐D Echocardiographic Analysis of the Equine Aortic Valve [PDF]

open access: yes, 2019
Aortic regurgitation (AR) can be a normal function of aging or a disease in younger horses. Symptoms range from no outward signs to decreased performance to sudden cardiac arrest.

Qualitative grading of aortic regurgitation: a pilot study comparing CMR 4D flow and echocardiography. [PDF]

open access: yes, 2015
Over the past 10 years there has been intense research in the development of volumetric visualization of intracardiac flow by cardiac magnetic resonance (CMR).This volumetric time resolved technique called CMR 4D flow imaging has several advantages over ...
