 Percutaneous coronary intervention PCI with drug-eluting stent DES implantation currently represents the dominant treatment strategy in patients undergoing catheter intervention. However, effective neointimal suppression occurs at the cost of a systematic delay in arterial healing in comparison with after bare metal stenting. This underlies a small but significant increased risk of stent thrombosis after DES implantation in comparison with bare metal stent implantation as well as a possible excess of in-stent neoatheroma formation. To address this issue recent technological advances have focused on bioresorbable polymer coatings and the development of stents with fully resorbable backbones.
