Abstract/OtherAbstract:
Quantitative assessments of haemolysis, thromboembolism and endothelial damage are established using computational fluid dynamics and documented threshold values. The régime studied was steady forward (systolic) flow through a fully open Starr-Edwards model 1260 ball valve, in an aortic shaped chamber. Modelling was carried out using finite difference techniques for turbulent, Newtonian flow. Haemolysis was not predicted "in-bulk", but a haemolytic potential as high as 30% was suggested at prosthetic surfaces. Also a 10% thromboembolic potential and a 6% potential for endothelium damage were noted.
