Summary

This work describes the design and manufacture of a miniaturised, autoclavable synthetic vascular graft intended for coronary artery bypass grafting (CABG) applications where autologous vessels are unavailable. The graft combines elastin-like recombinamers hydrogel with native silk fibroin textile to achieve mechanical properties equivalent to autografts whilst supporting biological integration through endothelial monolayer formation. Successful in vitro anastomosis to human vessels demonstrates clinical implantation potential and suggests the construct could reduce morbidity by obviating the need for a second surgical harvest site.

UK applicability

If successfully translated to clinical practice, such a graft could benefit UK patients with coronary artery disease by reducing surgical morbidity and expanding graft options when autologous vessels are unsuitable. However, the study is at the laboratory stage and does not yet demonstrate in vivo efficacy or long-term patency in UK or other clinical populations.

Key measures

Mechanical performance (suture retention, compliance), luminal patency, morphological homogeneity, endothelial cell monolayer formation, in vitro anastomosis success, compliance to ISO 7198 guideline

Outcomes reported

The study evaluated mechanical performance, morphological characteristics, and biological integration of a miniaturised synthetic vascular graft composed of elastin-like recombinamers hydrogel and silk fibroin textile. The graft demonstrated suture retention and compliance comparable to autografts, supported endothelial monolayer formation, and achieved successful in vitro anastomosis to human vessel tissue.
