abstract

Every year, over 250,000 patients undergo heart valve implantation [1]. Approximately 55% of implanted prosthetic heart valves (PHV) are mechanical. Patients must undergo lifelong anticoagulant medication in order to alleviate the risk of thrombus formation. In order to understand the complex fluid dynamics underpinning problems such as thrombosis, detailed high-resolution quantitative information on the flow field in PHVs is essential [2]. High-resolution data is also needed for the validation of Computational Fluid Dynamics (CFD) studies.
