Key result
A PEEK-g-PMPC mechanical valve demonstrated no thrombus formation compared to an untreated PEEK valve in a short-term (<26 h) porcine aortic valve replacement model.
Why the study?
It remained unclear whether material-related features could provide a practical level of thromboresistance to mechanical heart valves to reduce thromboembolism and anticoagulation requirements.
Does a PEEK-g-PMPC mechanical heart valve prevent thrombus formation compared to an untreated PEEK valve in a porcine aortic valve replacement model without anticoagulation?

May reduce thrombosis in mechanical valves without anticoagulation; hypothesis-generating and requires human trials before clinical consideration.
Does a PEEK-g-PMPC mechanical heart valve prevent thrombus formation compared to an untreated PEEK valve in a porcine aortic valve replacement model without anticoagulation?
A PMPC-grafted PEEK mechanical heart valve demonstrated improved short-term thromboresistance without anticoagulation in a porcine model, though fibrous fouling remains an issue.
Kambe et al. (2019) studied aortic valve replacement (porcine model). PEEK-g-PMPC mechanical heart valve vs. untreated PEEK valve was evaluated on thrombus formation. A PEEK-g-PMPC mechanical valve demonstrated no thrombus formation compared to an untreated PEEK valve in a short-term (<26 h) porcine aortic valve replacement model.
