Pulmonary expanded polytetrafluoroethylene valved conduits showed sufficient opening and sinus size-dependent suppression of turbulent flow, potentially improving durability.
Does the presence and size of a sinus improve hydrodynamic performance in pulmonary expanded polytetrafluoroethylene valved conduits in vitro?
The inclusion of a sinus in pulmonary ePTFE valved conduits suppresses turbulent flow in vitro, which may improve durability depending on the sinus size.
Absolute Event Rate: 0% vs 0%
All models exhibited sufficient opening and acceptable Reynolds shear stress values. The sinus contributed to suppression of turbulent flow, which may lead to improvement of conduit durability, but its effect was dependent on the sinus size.
