Technical success and long-term experience of a novel radial guide-catheter shape: the JCLRAD.

ABSTRACT

Objectives: Percutaneous coronary intervention (PCI) via the transradial route has been widely adopted over the transfemoral route, but guide catheter selection remains limited. We present our experience with a novel guide catheter design, the Judkin's Curve Left- Radial (JCLRAD, Medtronic), which is optimized for transradial PCI to the left coronary system. Methods: Sequential patients who underwent PCI using the JCLRAD catheter over a 3-year period (October 1, 2017 to November 1, 2020) were included in the analysis. Prospectively collected data were extracted from the institutional NCDR CathPCI registry with supplemental medical record review to collect clinical and procedural data. Results: PCI was performed in 2347 patients and 4070 lesions using the JCLRAD guide catheter. The mean age was 65.5 ± 11.7 years, and 72.1% of the population were male; 52.5% of patients presented with acute coronary syndrome. The lesion complexity was high (66.7% Class B2/C by ACCAHA classification) with a 7% use of atherectomy. Procedural success was 99.6% with no identified cases of iatrogenic catheter-induced coronary dissection. Conclusions: In this single-center retrospective study, the use of the JCLRAD was associated with a high success rate and low rates of complications, including no guide catheter-induced dissection in a cohort of patients with complex coronary anatomy. This is the first-reported large clinical experience with this novel radial left coronary system guide catheter.
