title: Randomized Comparison of a Biodegradable Polymer Ultrathin Strut Sirolimus-Eluting Stent With a Biodegradable Polymer Biolimus-Eluting Stent in Patients Treated With Percutaneous Coronary Intervention: The SORT OUT VII Trial.
abstract: Coronary drug-eluting stents with biodegradable polymers have been designed to improve safety and efficacy.
  
  
  
  The Scandinavian Organization for Randomized Trials With Clinical Outcome (SORT OUT) VII trial-a large-scale registry-based randomized, multicenter, single-blind, 2-arm, noninferiority trial-compared 2 biodegradable polymer drug-eluting stents: the thin-strut cobalt-chromium sirolimus-eluting Orsiro stent and the stainless steel biolimus-eluting Nobori stent in an all-comer patient population. The primary end point target lesion failure was a composite of cardiac death, myocardial infarction (not related to other than index lesion), or target lesion revascularization within 1 year, analyzed by intention to treat (noninferiority margin of 3.0%). Clinically driven event detection based on Danish registries was used. A total of 1261 patients were assigned to receive the sirolimus-eluting stent (1590 lesions) and 1264 patients to the biolimus-eluting stent (1588 lesions). At 1 year, the composite end point target lesion failure occurred in 48 patients (3.8%) in the sirolimus-eluting group and in 58 patients (4.6%) in the biolimus-eluting group (absolute risk difference, -0.78% [upper limit of 1-sided 95% confidence interval, 0.61%]; P<0.0001). Rates of definite stent thrombosis occurred in 5 (0.4%) of the sirolimus-eluting group compared with 15 (1.2%) biolimus-eluting stent-treated patients (rate ratio, 0.33; 95% confidence interval, 0.12-0.92; P=0.034), which largely was attributable to a lower risk of subacute definite stent thrombosis: 0.1% versus 0.6% (rate ratio, 0.12; 95% confidence interval, 0.02-1.00; P=0.05).
  
  
  
  The thin-strut sirolimus-eluting Orsiro stent was noninferior to the biolimus-eluting Nobori stent in unselected patients for target lesion failure at 1 year.
