title: The effects of drug-eluting stent polymer on measurement of strut thickness by optical coherence tomography: in-vitro comparison with bare-metal stent.
abstract: BACKGROUND
  Although measurement of stent strut by optical coherence tomography (OCT) is important as an index for evaluating incomplete stent apposition, the effects of drug-eluting stents (DES) polymer on it are unknown.
  
  
  RESULTS
  DES and bare-metal stents (BMS) as platforms of DES were implanted in an artificial artery. Thickness of stent strut, defined as a distance from inner surface of the strut to the adjacent surface of the tube, and thickness of high-signal band were measured by OCT. Each measurement of DES was significantly larger comparing with BMS.
  
  
  CONCLUSIONS
  This in-vitro study demonstrates that DES polymer may influence OCT measurement for the stent strut.
