Percutaneous transluminal coronary angioplasty with stenting has now become one of the cornerstones of treatment for coronary artery disease. The use of third-generation drug-eluting stents (DES) is currently the preferred method of treatment for different indications in patients with coronary artery disease. Self-expanding stents are routinely used in peripheral arterial disease, like external iliac and femoropopliteal percutaneous interventions. Self-expanding stents have been in use since the beginning of PCI. Although the first stent deployed was of the self-expanding variety, namely the Wallstent, balloon-expandable stents have become the stents of choice in the coronary arteries. The role of self-expanding stents in modern PCI is continuously evolving. This review discusses the utility of self-expanding stents in the treatment of specific subsets of coronary lesions.
