Comparison of 12-month angiographic outcomes between repeat drug-eluting stent implantation and drug-coated balloon treatment for restenotic lesion caused by stent fracture

摘要: We aimed to compare the angiographic outcomes between repeat drug-eluting stent (DES) implantation and drug-coated balloon (DCB) treatment for restenotic lesion caused by fracture (SF). The of SF after DES has not been well evaluated. From April 2007 2015, 9320 lesions were implanted with a during percutaneous coronary intervention in our hospital; those, 815 (8.7%) showed restenosis on follow-up angiogram. study subjects 47 consecutive patients 69 treated target revascularization (TLR); 27 45 TLR (either cobalt–chromium or platinum–chromium everolimus-eluting zotarolimus-eluting stent; group), 20 24 DCB (DCB group) TLR. 12-month cumulative incidence predictors was Restenosis re-restenosis defined as % diameter stenosis > 50% complete partial separation strut assessed plain fluoroscopy. Baseline characteristics similar groups. binary rate group 44.4% 37.5% (p = 0.58) 43.9% 31.9% (p = 0.31), respectively. On multivariate analysis, vessel hinge movement an independent predictor (p = 0.02, hazard ratio: 6.54, 95% confidence interval 1.30–32.8). high both After treating implantation, mechanical stress leads further interventional treatment, regardless type device used.
