Advanced Techniques: Use of Drug-Eluting Stents

Cardiologists who perform PTCA procedures at Strong Memorial Hospital use drug-eluting stents in appropriate patient situations.

Restenosis (renarrowing or reblockage) of an opened coronary artery after percutaneous transluminal coronary angioplasty (PTCA) with a bare-metal stent (a tiny, expandable metal coil that is inserted into the newly opened area of the artery to help keep the artery from narrowing or closing again) occurs at rates of up to 30% in some groups of patients. This restenosis may require one or more additional procedures to reopen the artery (The New England Journal of Medicine, October 2, 2003: 349(14); 1315-1323).

The use of drug-eluting stents (stents containing medication that helps prevent restenosis by gradually releasing the medication over time) has been shown to decrease restenosis after PTCA and stent placement, as well as to decrease the need for additional procedures to reopen an artery (Journal of the American College of Cardiology, February 18, 2004: 43(4); 507-512).
