Abstract:
BACKGROUND AND OBJECTIVES: Since 1987, coronary stents have changed the pattern of practice of interventional cardiology, by reducing the complications and improving the clinical outcomes. However, coronary stent restenosis still remains a significant clinical problem in the field of interventional cardiology. The aim of this trial was to compare the clinical efficacy of a rotational atherectomy (ROTA), with that of a plain old balloon angioplasty (POBA), in patients with coronary stent restenosis. SUBJECTS AND METHODS: One hundred and three patients (men 80, 58.4+/-10.3 years of age), diagnosed with coronary stent restenosis, at Chonnam National University Hospital, between January 1999 and December 2000, were analyzed. The clinical end-points were the occurrence of major adverse cardiac events (MACE): death, myocardial infarction and target lesion revascularization (TLR) during the one-year clinical follow-up. RESULTS: The baseline clinical and angiographic characteristics were similar between the two groups. Before the percutaneous coronary intervention (PCI), the diameter of stenosis of the POBA and ROTA groups were 81.9+/-14.0 and 82.9+/-10.0%, respectively, which decreased to 25.5+/-15 and 22.7+/-12% after treatment. At the one-year clinical follow-up, the TLR rates were 7.0 and 6.3% in the POBA and ROTA groups, respectively. The MACE results were not different between the two groups (7.0 and 9.4% in the POBA and ROTA groups, respectively). CONCLUSION: There was no significant long-term clinical benefit of a rotational atherectomy prior to a POBA, compared with a POBA alone, for the treatment of coronary stent restenosis.
