Elevated cyclic stretch alters matrix remodeling in aortic valve cusps: implications for degenerative aortic valve disease.

Matrix metalloproteinases (MMPs) and cathepsins are proteolytic enzymes that are upregulated in diseased aortic valve cusps. The objective of this study was to investigate whether elevated cyclic stretch causes an increased expression and activity of these proteolytic enzymes in the valve cusp. Circumferentially oriented fresh porcine aortic valve cusp sections were stretched to 10% (physiologi...

Cause of degenerative disease of the trileaflet aortic valve.

Risk factors for both atherosclerotic aortic wall disease and degenerative disease of the trileaflet aortic valve are very similar if not identical. This correlation grows even stronger as the person advances in years. Because of this, it is the prevailing view that sclerosis of the trileaflet aortic valve, unless previously affected by septic or rheumatic endocarditis, is a disease similar in ...

Severe Aortic Regurgitation in Degenerative Bioprosthetic Aortic Homograft Treated by Valve in Valve

Bioprosthetic valves are increasingly used in patients with aortic valve stenosis. In comparison with mechanical valves, these valves have a lower risk of thromboembolism and no need for anticoagulation [1,2]. However, the durability is limited; the best current valves are expected to degenerate in 10 to 20 years, resulting in stenosis or regurgitation or combined pathology. Surgical aortic val...

C-reactive protein in degenerative aortic valve stenosis

Degenerative aortic valve stenosis includes a range of disorder severity from mild leaflet thickening without valve obstruction, "aortic sclerosis", to severe calcified aortic stenosis. It is a slowly progressive active process of valve modification similar to atherosclerosis for cardiovascular risk factors, lipoprotein deposition, chronic inflammation, and calcification. Systemic signs of infl...
