Why the study?
Does the ATS Open Pivot Valve compared to the St. Jude Regent Valve improve hemodynamic and thrombogenic performance in a computational fluid dynamics model?

A computational model demonstrates that differences in hinge mechanisms between the ATS and SJM mechanical heart valves lead to different potentials for platelet activation during the regurgitation phase.
No takes yet. Share an insight, caveat, or question.
May suggest lower thrombogenicity for ATS valve; computational findings leave clinical relevance open.
Dumont et al. (2007) studied this question.
