Answer

Intracoronary stents have the following features:

  • Stents differ with respect to composition (eg, cobalt chromium or platinum chromium), architectural design, delivery system and the drug delivered
  • Drug-eluting stents (DESs) have demonstrated significant reductions in restenosis and target-lesion revascularization rates, with further reduction with the second-generation DESs (compared with first-generation DESs or bare-metal stents [BMSs])
  • In the United States, the commercially available DESs are second-generation models that elute everolimus and zotarolimus
  • Both stents with bioabsorbable polymer and fully bioresorbable scaffolds have been approved by the FDA and are available for commercial use in the United States
  • Stents are conventionally placed after balloon predilation, but in selected coronary lesions, direct stenting may lead to better outcomes
