 Coronary stents are the default devices for the treatment of coronary artery disease in percutaneous coronary intervention PCI according to existing guidelines. However, thrombosis and restenosis are still the main limitations of current permanent metallic stents. In contrast to Bare Metal Stents BMSs, Drug Eluting Stents DESs have a reduced restenosis rate due to the presence of antiproliferative agents in the coating layer of the stent surface and reduced rate of repeat revascularisation. However, late and very late stent thrombosis remains the limitation of DES in spite of prolonged dual antiplatelet therapy.Bioabsorbable scaffolds have been introduced to overcome limitations of permanent metallic stents.
