Successful transapical aortic valve replacement in a patient with a previous mechanical mitral valve replacement.

30 Oct 2009 In this case we illustrate our experience with transapical minimal invasive aortic valve replacement in a patient who previously underwent mitral valve replacement. The implantation did not interfere with the existing prosthesis and could even be ... Read more...

Mechanical strain and the aortic valve: influence on fibroblasts, extracellular matrix, and potential stenosis.

30 Oct 2009 BACKGROUND: Mechanical strain may affect aortic valve cusp, leading to an altered extracellular matrix ultrastructure and eventually aortic stenosis. The aim of this study was to evaluate the affect of these potential relationships on human tissue. ... Read more...

Transcatheter aortic valve implantation in patients with very high risk for conventional aortic valve replacement.

30 Oct 2009 BACKGROUND: We sought to determine whether transcatheter aortic valve implantation is a reasonable treatment option in patients with a very or extremely high risk for conventional aortic valve replacement, presenting with a logistic EuroSCORE ... Read more...

Technical information about 'Aortic Valve Stenosis'

Definition: A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
