title: [Multicentric experience with the use of Sheathless 6.5 French-size catheter in coronary angioplasty for bifurcation lesions: feasibility and safety].
abstract: BACKGROUND
  Transradial intervention of coronary lesion is increasing in frequency and is associated with lower major vascular access site complications. However, the small size of the radial artery is a major limitation of this technique, especially for bifurcation lesions, because 6-French guiding catheters are necessary to optimize the technique. A Sheathless guiding catheter has recently been introduced, optimizing a large lumen with a small size.
  
  
  OBJECTIVE
  The aim of this study is to report our preliminary experience performing bifurcated transradial interventions using a 6.5 French Sheathless guide catheter.
  
  
  METHODS
  From March 2009 to February 2012 in three hospitals, 46 consecutive patients were enrolled in this study who underwent transradial approach (TRA) for percutaneous bifurcation coronary interventions using the 6.5 French Sheathless Eaucath guiding catheter system because of small radial artery caliber.
  
  
  RESULTS
  In this study, 46 patients were enrolled with mean age of 72.13 ± 16.41 years. The majority of patients were females with sex-ratio 0.53. Procedural success using the 6.5 French Sheathless guide catheter system was 100 % with no cases requiring conversion to a conventional guide and catheter system. During procedures, adjunctive devices used in this cohort included IVUS (2 patients), 35 bifurcated lesions were treated with a kissing-balloon technique in the group of 46 patients undergoing bifurcation PCIs, one patient required rotational atherectomy, thrombus-aspiration catheters had used in four patients, FFR-guided angiography in four patients. We report one case of chronic total occlusion bifurcated lesion successfully treated using this hydrophilic catheter. There were no radial artery site complications.
  
  
  CONCLUSIONS
  The treatment of coronary bifurcation lesions with 6.5 French Sheathless guiding catheter by transradial approach is feasible and appears safe in this multicenter study.
