Moderate upsizing to a 25 mm artificial aortic valve improves haemodynamics without adverse flow effects, but 27 mm upsizing increases stress and thrombosis risk.
Does upsizing artificial aortic valves impact haemodynamic performance and thrombosis risk in a computational model?
In a computational model, moderate upsizing of artificial aortic valves to 25 mm optimizes haemodynamics, but excessive upsizing to 27 mm may increase thrombosis risk.
Absolute Event Rate: 0% vs 0%
Moderate upsizing to a 25 mm valve improves haemodynamic performance without introducing adverse flow effects, while further upsizing to 27 mm increases stress and turbulence, raising thrombosis risk.
