Background: In patients with complex coronary anatomy, stent delivery can be challenging and result in procedural failure and complications. N2 - Objectives: To investigate the utility and safety of the GuideLiner "mother-and-child" catheter system during transradial and transfemoral percutaneous coronary intervention (PCI). T1 - Experience and complications associated with use of guide extension catheters in percutaneous coronary intervention A decline in device-associated complications over time may be attributed to operator learning curve, patient selection, and improvement in catheter design.",
#GUIDELINER SERIES#
Conclusions: In this consecutive series of GuideLiner supported PCI, the guide extension system enabled procedural success in the majority. Coronary dissection attributed to GuideLiner occurred in 3.3% (12/363) and became less frequent over the study period. Stent deformation associated with GuideLiner use occurred in 2.2% (8/363), with the incidence of this complication decreasing over device iterations. Procedural success resulting in successful device delivery with the GuideLiner catheter was 80.2%. Type C lesions were present in 78% of GuideLiner cases. 67.8, P<0.001) and had more multivessel disease (72% vs. Patients in the GuideLiner group were older (mean age 71.5 vs. Results: A total of 363 cases of GuideLiner-facilitated PCI were identified from 6,088 unique PCI procedures performed during this same time period. Patients who underwent PCI without GuideLiner use during the same time period were used as controls for comparison. Methods: Single center retrospective study of PCI utilizing the GuideLiner catheter between February 2010 and October 2014. The purpose of this study was to evaluate procedural success and safety in a series of GuideLiner-facilitated PCI. The GuideLiner is a coaxial guide extension system designed to enable deep vessel engagement and facilitate device delivery. A decline in device-associated complications over time may be attributed to operator learning curve, patient selection, and improvement in catheter design.Ībstract = "Objectives: To investigate the utility and safety of the GuideLiner catheter system during transradial and transfemoral percutaneous coronary intervention (PCI).
