Material transport in the left ventricle with aortic valve regurgitation [PDF]
Physical Review Fluids, 3(11), 113101 (2018), 2018 This experimental in vitro work investigates material transport properties in a model left ventricle in the case of aortic regurgitation, a valvular disease characterized by a leaking aortic valve and consequently double-jet filling within the elastic left ventricular geometry.

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

Monaldi 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.

Aortic valve replacement with preserved aortic valve homografts
The Journal of Thoracic and Cardiovascular Surgery, 1974 A total of 229 patients underwent aortic valve replacement with a preserved aortic valve homograft during a 7½ year period. The operative mortality rate was 4.8 per cent. Statistical analysis of follow-up data indicated that, for patients who survived the first 30 days after surgery, the 4 year survival rate was 94 per cent and the 7 year survival was ...

Quality of life after aortic valve repair is similar to Ross patients and superior to mechanical valve replacement: A cross-sectional study [PDF]
, 2016 Background: In patients after aortic valve surgery, the quality of life is hypothesized to be influenced by the type of the valve procedure. A cross-sectional study on the postoperative quality of life was carried out in patients after aortic valve ...

European Heart Journal-Cardiovascular Imaging, 2017 Echocardiography is the key tool for the diagnosis and evaluation of aortic stenosis. Because clinical decision-making is based on the echocardiographic assessment of its severity, it is essential that standards are adopted to maintain accuracy and ...

Immersed boundary model of aortic heart valve dynamics with physiological driving and loading conditions [PDF]
Int J Numer Meth Biomed Eng, 28(3):317-345, 2012, 2017 The immersed boundary (IB) method is a mathematical and numerical framework for problems of fluid-structure interaction, treating the particular case in which an elastic structure is immersed in a viscous incompressible fluid. The IB approach to such problems is to describe the elasticity of the immersed structure in Lagrangian form, and to describe ...

Bicuspid aortic valve associated with aortic thrombotic occlusion
The 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.

A novel source of arterial valve cells linked to bicuspid aortic valve without raphe in mice
eLife, 2018 Abnormalities of the arterial valve leaflets, predominantly bicuspid aortic valve, are the commonest congenital malformations. Although many studies have investigated the development of the arterial valves, it has been assumed that, as with the ...

Advanced Functional Materials, EarlyView.Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...
