To evaluate the effect of cutting balloon (CB) angioplasty on the outcome of self-expanding coronary stent implantation, we compared the results of Radius stent implantation using two predilation strategies. Seventy de novo lesions in 70 patients (60 men) were included in the study. Stenting was performed after conventional angioplasty (n = 38, group 1) or CB angioplasty (n = 32, group 2). In-stent restenosis (ISR) rates of each group were 39 and 10% at 6-month follow-up (p = 0.02). Major adverse cardiac events occurred in 20 and 11%, respectively (p = 0.25). Multivariate analysis revealed that ISR was predicted only by lesion length ≥20 mm. In conclusion, CB angioplasty did not reduce ISR after Radius stent implantation, when other independent risk factors, such as lesion length, were taken into consideration.
