Abstract

Restenosis prevention has been the 'holy grail' of contemporary interventional cardiology. Even though balloon angioplasty has become the standard treatment for ischemic syndromes, it is still plagued by a definite incidence of restenosis. This recidivism has prompted the search for newer, catheter-based modalities of treatment to address this issue. The proliferation of newer devices for intervention has increased the number of options for the interventional cardiology; however, until recently, none has had a significant impact on restenosis. The randomized trials (STRESS and BENESTENT) have both shown a significant reduction in angiographic restenosis with the Palmaz-Schatz stent in de novo coronary lesions. Nonrandomized trials suggest additional benefit in saphenous vein bypass grafts.
