Bioprosthetic Heart Valves: Impact of Implantation on Biomaterials
, 2013 Prosthetic heart valves are commonly used in the treatment of valvular heart disease. Mechanical valves are more durable than the bioprosthetic valves; however, the need for long-term anticoagulant therapy renders them unsuitable for some patient groups.

Fluid-structure interaction simulations of venous valves: a monolithic ALE method for large structural displacements [PDF]
arXiv, 2018 Venous valves are bicuspidal valves that ensure that blood in veins only flows back to the heart. To prevent retrograde blood flow, the two intraluminal leaflets meet in the center of the vein and occlude the vessel. In fluid-structure interaction (FSI) simulations of venous valves, the large structural displacements may lead to mesh deteriorations and
