Coronary artery stents were first developed in the 1980s and are now placed in most percutaneous coronary interventions (PCIs). Interventional cardiologists have a wide choice of stents for implantation. The choices range from bare-metal stents (BMSs) and drug-eluting stents (DESs) (Table 144-1) that are widely used in contemporary practice to new stents, such as DESs with novel coatings, biodegradable stents, DESs with biodegradable polymers, DESs that are polymer free, dedicated bifurcation stents, and self-expanding stents. A number of DESs are currently undergoing study or are available outside the United States (Table 144-2).
