Imaging of Explanted Mechanical Heart Valves
Microscopy and Microanalysis, 1998 Abstract Prosthetic mechanical heart valves (MHVs) made from pyrolytic carbon (PYC) are a highly successful biomaterial application due to their excellent durability and clinically adequate blood compatibility. Their thromboresistance has been attributed to a combination of hemodynamics, material inertness, and surface properties which ...

Effect of cyclic deformation on xenogeneic heart valve biomaterials.
PLoS ONE, 2019 Glutaraldehyde-fixed bovine pericardium is currently the most popular biomaterial utilized in the creation of bioprosthetic heart valves. However, recent studies indicate that glutaraldehyde fixation results in calcification and structural valve ...

klf2a couples mechanotransduction and zebrafish valve morphogenesis through fibronectin synthesis
Nature Communications, 2016 In the developing heart, blood flow transmits mechanical signals to progenitor cells that ultimately leads to valve formation. Here, the authors identify the origin of the valve progenitor cells and fibronectin1bas a transcriptional target of the ...

Transvalvular mitral regurgitation following mitral valve replacement a diagnostic dilemma
Annals of Cardiac Anaesthesia, 2015 After mitral valve replacement with a prosthetic valve, the valve should be competent and there should not be any residual prosthetic valve regurgitation. Transvalvular residual prosthetic valve regurgitation are difficult to diagnose and quantify.
