Comparison of Guideliner versus Cuideplus catheter in complex percutaneous coronary interventions

摘要

The adequate back-up support of the guide catheter is a crucial step in complex percutaneous coronary interventions (PCI). GuideLiner catheter provides extra back-up support and coaxial guide engagement for stent delivery in complex PCI [1,2]. In a recent article of your journal, Tsukui et al. [3] compared device performance of the conventional guide extension catheter (GuideLiner, Vascular Solutions Inc., Minneapolis, MN) and the soft guide extension catheter (Guideplus, Nipro, Osaka, Japan). They have demonstrated that device unsuccessful rate was lower in the Guideplus catheter than in the GuideLiner catheter and therefore proposed that Guideplus catheter provided better performance as the guide extension catheter. We would like to provide some comments and contribution to this study.
