A build-up of fatty substances in the coronary arteries may reduce blood supply to the heart, causing coronary artery disease. To restore blood flow, a drug-eluting stent can be inserted into a coronary artery during percutaneous coronary intervention (PCI).
Drug-eluting stents are made from metal and coated with an antiproliferative drug. These vary between stents. In some stents the drug is applied on a durable or absorbable polymer, whereas others are polymer free. Each drug-eluting stent has an instructions for use (IFU) document that includes the indications for which the device can be used. The indications for use vary and may specify subpopulations or lesion types. They often specify the size of vessels the stent can be used for. Some stents can be purchased for use in specific cases because they are indicated for a particular subpopulation or lesion type, or because they have certain design features.
This assessment included 29 drug-eluting stents (table 1) available through the NHS Supply Chain. Each stent had valid CE certification as a class 3 implantable device.
