• Comparison of the device performance between the conventional guide extension catheter and the soft guide extension catheter

    Abstract

    Background

    The guide extension catheter is frequently used in current percutaneous coronary intervention, and the GuideLiner (Vascular Solutions Inc., Minneapolis, MN) has been the standard guide extension catheter. Recently, the Guideplus (Nipro, Osaka, Japan) has emerged as a new guide extension catheter. The aim of the present study was to compare device performance between the Guideplus and GuideLiner.

    Methods

    We compared the purpose of guide extension catheter and the device unsuccessful rate between the Guideplus and GuideLiner. We classified the purpose of guide extension catheter into 4 categories: (1) to advance devices into the target lesion, (2) to engage guide catheter into the ostium, (3) to support the small profile balloon crossing the CTO or 99% stenosis that the microcatheter could not cross, and (4) others.

    Results

    Ninety-two lesions were classified as the Guideplus group, whereas 103 lesions were classified as the GuideLiner group. The purpose of guide extension catheter was significantly different between the 2 groups ( < 0.001). The Guideplus was frequently used to support the small profile balloon crossing the CTO or 99% stenosis (20.7%), whereas the GuideLiner was not used (0%). The device unsuccessful rate was significantly less in the Guideplus (8.7%) than in the GuideLiner (20.4%) ( = 0.022).

    Conclusions

    The purpose of guide extension catheter was significantly different between the Guideplus and GuideLiner. The Guideplus was more frequently used to support the small profile balloon crossing the CTO or 99% stenosis. The device unsuccessful rate was less in the Guideplus, which may suggest the better performance as the guide extension catheter.

    Highlights

     

    • The guide extension catheter is frequently used in current percutaneous coronary interventions.
    • The GuideLiner has been the standard, whereas the Guideplus has emerged as a new guide extension catheter.
    • The device unsuccessful rate was less in the Guideplus, which may suggest the better performance.
