ABSTRACT
BACKGROUND:
Drug-coated balloon (DCB) is a device for treating patients with in-stent restenosis; however, there are scant data on its efficacy for stent edge restenosis (SER). This study aimed to investigate the clinical outcomes of DCB use for treating SER compared with new-generation drug-eluting stent (DES) implantation.METHOD:
From December 2013 to January 2019, patients who underwent DES implantation or DCB for SER were enrolled. Clinical outcomes were analyzed, and propensity score with matching was conducted. The primary outcome was target-vessel revascularization (TVR). The secondary outcomes were the incidence of all-cause mortality, major adverse cardiovascular events (MACE), and target lesion revascularization (TLR).RESULT:
A total of 291 patients with SER were included 160 were treated with DCB, and 131 with new-generation DES. DCB treatment for SER treatment was associated with a lower risk of TVR than DES [hazard ratio, 0.549; 95% confidence interval (CI), 0.339-0.891] at a median follow-up of 1080 days (interquartile range; 729-1080 days). Propensity score matching (PSM) was performed to adjust for baseline clinical and lesion characteristics. After PSM, no significant difference in the risk of TVR was observed (hazard ratio, 0.965; 95% CI, 0.523-1.781). Similarly, the risk for all-cause death (hazard ratio, 0.507; 95% CI, 0.093-2.770), MACE (hazard ratio 0.812; 95% CI, 0.451-1.462), and TLR (hazard ratio 0.962; 95% CI, 0.505-1.833) were comparable between the two groups.CONCLUSION:
DCB treatment efficacy for SER was similar to that of new-generation DES after PSM. DCB is a significant alternative to obtain comparable results with new-generation DES for the treatment of SER.
