The Guideliner Catheter: a Useful Tool in the Armamentarium of the Interventional Cardiologist.

Regardless of the clinical setting, a good back-up represents one of the most important conditions to ensure guidewire andballoon advancement and stent delivery. As a “mother and child” system, the Guideliner catheter (Vascular Solutions Inc.,Minneapolis, MN, USA) provides an extension to the guide catheter with better coaxial alignment and stability. We reporttwo didactic cases showing the usefulness of the Guideliner device in everyday catheterization laboratory practice. Thefirst case was a primary percutaneous coronary intervention (PCI) in a 71-year-old diabetic man admitted for inferior STelevationmyocardial infarction, related to tight proximal stenosis in a dominant tortuous and calcified left circumflex. Thesecond case was an elective PCI in a 76-year-old man admitted for stable angina (Canadian Cardiovascular Society [CCS]class III), related to focal intra-stent restenosis of a saphenous venous graft to the left anterior descending. In both cases, theGuideliner catheter provided a good back-up insuring the success of PCI and drug-eluting stents implantation, with a goodin-hospital outcome.
