“…Designers often focus on using hydrodynamic features and hemolysis to evaluate the blood pump performance during optimization design, but lack awareness of other important blood component damage, such as device‐induced platelet activation, which is an important factor for thrombosis formation in patients supported with blood pump. Chang et al 16 analyzed the effect of different shroud coverage on blood damage in a centrifugal blood pump and found that less shroud coverage resulted in better improvements in hemolysis. Wu et al 17 studied the influence of blade top clearance on hemolysis and hydraulic performance in a semi‐open centrifugal blood pump and obtained an optimum blade top clearance.…”

“…In addition, according to the MIH (9.87 ± 0.93 [mean ± SD]) results predicted by CFD, the hemolysis performance of the RDBP was excellent. A similar computational study of centrifugal pumps using the same hemolysis model generated MIH values in the range of 1350–1810; this comparison is encouraging 46 . In the future, rotor design for the RDBP can be even further optimized to achieve better hemolytic performance.…”

“…Taskin et al 29 investigated the effect of closed and semi‐open impellers on the hemolysis performance of blood pumps. Chang et al 30 investigated the effect of different shroud coverage ratios on the hemolysis performance of blood pumps. While, these studies did not investigate the effect of the presence or absence of shroud or coverage on the thrombotic potential of the blood pump.…”
