title: Usefulness and safety of a guide catheter extension system for the percutaneous treatment of complex coronary lesions by a transradial approach.
abstract: OBJECTIVE
  The aim of this study was to describe our initial experience with the GuideLiner® catheter (Vascular Solutions Inc.) in the transradial treatment of complex lesions.
  
  
  METHODS
  The clinical, angiographic and procedural data of percutaneous coronary interventions where GuideLiner was used during 2013 were collected. The transradial approach was used in all cases. The indication for its use, efficacy and periprocedural complications were determined. Sixteen consecutive procedures (in 15 patients; 12 males and 3 females) were evaluated. The indication for the use of GuideLiner was a difficulty to advance and properly position a stent through a tortuous and/or calcified artery despite using high-support guide catheters or other useful techniques.
  
  
  RESULTS
  Of the 16 angiographic procedures, 14 (87.5%) were successful (stent deployment in 13 cases and a drug-eluting balloon in 1 case). Unsuccessful cases were a chronic total occlusion and a diffusely diseased left anterior descendant artery. A type B dissection of a proximal left circumflex artery was the only periprocedural complication.
  
  
  CONCLUSIONS
  Use of the GuideLiner was an effective and safe technique for the percutaneous treatment of complex coronary lesions in which the adequate progress of angioplasty devices had failed. GuideLiner was particularly helpful when using the transradial approach. Only one minor complication was recorded.
