A correlation between long-term in vitro dynamic calcification and abnormal flow patterns past bioprosthetic heart valves

In this paper, a long-term in vitro dynamic calcification of three porcine aortic heart valves was investigated using a combined approach that involved accelerated wear testing of the valves in the rapid calcification solution, hydrodynamic assessment of the progressive change of effective orifice area (EOA) along with the transaortic pressure gradient, and quantitative visualization of the flow. ...ViVitro Labs Inc. for providing access to their facility and equipment for this study.
