The GuideLiner catheter (Vascular Solutions, Minneapolis, MN) is a novel, rapid exchange catheter that allows deep vessel intubation. We describe 21 patients in whom the GuideLiner catheter [7 French (F) in 76% and 6F in 24%] was used to facilitate equipment delivery (n = 14) or vessel engagement (n = 7). Pressure dampening after GuideLiner catheter insertion was observed in 12 patients (57%). The procedure was successfully completed in 19 patients (90%) and one patient developed acute vessel closure, likely due to dissection. The GuideLiner catheter can facilitate complex coronary interventions but should be used with caution to minimize the risk for vessel injury.
