Abstract:
BACKGROUND: We have no information about the safety and effectiveness when we perform overdilating a sirolimuseluting stent(SES) with high pressure. In some specific animal model, the study reported overdilatation of SES with high pressure resulted in increase of restenosis. The aim of this study was to evaluate the safety and effectiveness of overdilatation of SES with high pressure. METHODS: 97 patients underwent PCI using SES between August 2003 and July 2005 were divided into two group(high pressure group, low pressure group), stents were implanted with high pressure(>18 atm) and low pressure(<12 atm). We compared between the two group of safety of stents, major adverse cardiac events(MACE), rate of restenosis, late loss. RESULTS: In high pressure group, there are more type C lesion(51% vs 38%, p<0.01). There were no significant differences between the two groups regarding MACE(12.8% vs 17.2%, p=0.78), in-stent restenosis rate(2.6 % vs 5.2%, p=0.65). There are small increasing of late loss in high pressure group, but no statistically significant difference(0.30 vs 0.15, p=0.05). CONCLUSION: Implantation of SES overdilated with high pressure is able to be performed safely to obtain wider inner lumen of stents.
