This success is particularly noteworthy in contrast to reported approaches by other researchers utilizing electrospun nanofibers, such as PLA, where fiber and pore electrospun grafts enhance neovascularization, and they often lead to significant blood leakage and premature loss of mechanical properties . Our coating method, closing the pores without compromising mechanical integrity, marks a crucial advancement, ensuring both leak-free functionality and future enhanced neovascularization, positioning fabricated structure as promising candidates for large animal models and potentially overcoming the challenges faced in previous designs. These findings demonstrate the potential of fabricated scaffold design as a suitable candidate for cardiovascular applications. Its ability to withstand blood pressure and minimize leakage aligns closely with the requirements of vascular grafts, offering a promising solution that bridges the gap between synthetic materials and the mechanical performance of natural vessels.
