title: The impact of intravascular ultrasound guidance during drug eluting stent implantation on angiographic outcomes.
abstract: OBJECTIVE
  Major limitation for the use of stent in the treatment of coronary artery disease is development of stent restenosis. The impact of intravascular ultrasound (IVUS) guidance during drug eluting stent (DES) implantation is presently not yet well established.
  
  
  METHODS
  For the present study, we included 30 patients who received DES with IVUS-guided stenting (Group A) and 30 patients receiving the DES without IVUS-guided stenting (Group B). The patients were evaluated for their ninth month control angiographies and were followed during two years for the development of relevant clinical events after the DES implantations. The angiographic and clinical results were compared between the groups.
  
  
  RESULTS
  After the percutaneous intervention, the minimal luminal diameter and net acute gain were significantly increased in Group A in respect to Group B (3.3 ± 0.34 vs. 2.8 ± 0.33, p < 0.01). Moreover, the rate for performing post-dilatation following stent implantation was higher in Group A than in Group B (p = 0.01). By contrast, stent restenosis rates were similar between the groups (p > 0.3).
  
  
  CONCLUSIONS
  The present results indicate that the use of IVUS for the implantation of DES can increase the success rate of the intervention. The IVUS guidance during DES implantation can be complementary percutaneous intervention, in particularly by detecting the situations that need for post-dilatation.
