Abstract:
Percutaneous coronary interventions (PCI) are the mainstay for treatment of advanced coronary disease. A majority of PCI involve deployment of a stent in the affected vascular segment. This chapter introduces the concept of using stents as a platform for delivering gene therapies to the vasculature with the overarching aim of mitigating in-stent restenosis (ISR), late stent thrombosis (LST), and neoatherosclerosis (NA), a triad of delayed complications that reduce the overall success rate of PCI. The chapter provides a detailed methodology for coatless reversible attachment of adenoviral (Ad) and adeno-associated viral (AAV) vectors to the metal stent struts along with representative in vitro and in vivo results.
