Abstract
The aim of this multicenter pilot study was to evaluate the acute safety and efficacy of the dexamethasone‐eluting stent (0.5 μg/mm2 of stent) implanted in patients with de novo single‐vessel disease. This study included 71 patients, 42% of whom had unstable angina pectoris. An appropriately sized BiodivYsio Matrix Lo stent loaded with a total dexamethasone dose of 0.5 μg/mm2 of stent was used. Technical device success rate was 95%. Six‐month MACE occurred in two patients (3.3%). Binary restenosis rate was 13.3%. Late loss was 0.45. Late loss and percent diameter stenosis were lower in the unstable angina pectoris patients compared to the stable patients (0.32 ± 0.39 vs. 0.60 ± 0.55 mm, P < 0.07, and 26.86 ± 14 vs. 38.40 ± 16%, P < 0.02). This study demonstrated the feasibility and safety of the implantation of a dexamethasone‐eluting stent and its effect on in‐stent neointimal hyperplasia. Catheter Cardiovasc Interv 2003;60:172–178.
