title: Outcome of patients treated by a novel thin-strut cobalt-chromium stent in the drug-eluting stent era: Results of the SKICE (Skylor in real world practice) registry.
abstract: OBJECTIVE
  To investigate the outcome of patients undergoing percutaneous coronary interventions (PCI) with implantation of a new thin-strut cobalt-chromium bare-metal-stent (BMS) in the drug-eluting-stent (DES) era.
  
  
  BACKGROUND
  Despite the contemporary penetration of DES in the clinical practice, a relevant percentage of patients are still treated by BMS. Data on clinical outcome of novel BMSs are lacking.
  
  
  METHODS
  This is a single-centre-registry enrolling patients treated by Skylor stent implantation. During the study, the criteria for BMS selection adopted at our institution ("internal" criteria) were as follows: (1) limited compliance to prolonged double antiplatelet therapy, (2) ST-elevation myocardial infarction (STEMI) or saphenous vein grafts (SVG) interventions, and (3) in the absence of these conditions, noncomplex (no bifurcations, no chronic total occlusions) lesions considered at low restenosis risk on the basis of arbitrary angiographic criteria (short lesions, large vessels). Primary and secondary end-points were respectively major adverse cardiovascular events (MACE) and target vessel failure (TVF) up to 9-month.
  
  
  RESULTS
  A total of 150 patients were treated with Skylor stent on 169 lesions. At 9-month follow-up, MACE occurred in 12 patients (8.0%) and TVF in 21 lesions (12.4%). By multivariable analysis, the predictors of MACE were Euroscore>or=9 and ejection fraction < 30% while the predictors of TVF were the absence of the angiographic criteria of low restenosis risk and ejection fraction < 30%.
  
  
  CONCLUSIONS
  In the DES era, the use of a last-generation BMS in patients with limited compliance to double antiplatelet therapy, STEMI or SVG interventions, and noncomplex angiographic lesions may be associated with acceptable clinical outcome.
