Abstract:
65 years old) with in-stent restenosis were randomly divided into two groups: cutting balloon(38 cases) and conventional balloon angioplasty(31 cases) group. Quantitative coronary angiography(QCA) and intravascular ultrasound(IVUS) were underwent before and immediately after the balloon inflation. Within 6-months clinical and angiographic follow-up, clinical improvements and QCA results were recorded. himary end points included myocardial infarction, coronary artery bypass graft(CABG) and revascularization. Results The procedural success rate was 100% in both groups. One patient in cutting balloon experienced dissection in the site distal to stent. Average follow-up time was (6.7?0.3) months. The angiographic stenosis rates at the 3- and 6-month in cutting balloon group were markedly lower than that in conventional balloon group(15% and 38% vs 18% and 43%, respectivelly, P
