Polycarbonate urethane and polyether urethane nonwovens as promising representatives of novel polymer heart valve materials were analysed regarding the susceptibility to calcification in comparison to porcine pericardium and polyamide 6. The applied method represents an accelerated calcification out of a metastable solution in short time with significant precipitates on the reference material. As our results show, urethane based nonwoven structures exhibit considerably lower susceptibility to calcification compared to pericardium as widely established material for leaflet design.
