Safety and efficacy of using Judkins left 3.5 guiding catheters for transradial right coronary artery intervention.

Abstract

There is limited data about the use of a Judkins left (JL) 3.5 guiding catheter for routine transradial right coronary artery (RCA) percutaneous coronary intervention (PCI). This study investigated the safety and efficacy of JL3.5 for RCA PCI. Patients with acute coronary syndrome (ACS) who underwent transradial RCA PCI between November 2019 and November 2020 at the Second Hospital of Shandong University were included. The study retrospectively compared JL 3.5 vs. other routine guiding catheters (GCs), including Judkins right (JR) 4.0 and Amplatz (left). Logistic multivariable analysis was used to analyze the factors associated with transradial RCA PCI success rate, in-hospital complications, and extra support. The study included 311 patients: 136 in the routine GC group and 175 in the JL 3.5 group. There were no significant differences between the two groups regarding in-hospital complications, extra support technics, or success. The multivariable analyses showed that coronary chronic total occlusion (CTO) was negatively associated with intervention success (OR = 0.06, 95% CI: 0.016-0.248, p < 0.001) but positively with extra support (OR = 8.74, 95% CI: 1.518-50.293, p = 0.015). Tortuosity was associated with extra support (OR = 16.50, 95% CI: 3.324-81.589, p = 0.001). In the JL 3.5 group, the left ventricular ejection fraction (OR = 1.11, 95% CI: 1.03-1.20, p = 0.006), CTO (OR = 0.07, 95% CI: 0.008-0.515, p = 0.009), and tortuosity (OR = 0.17, 95% CI: 0.03-0.95, p = 0.043) were independently associated with intervention success. JL 3.5 appears to be as safe and effective as the JR 4.0 and Amplatz (left) catheters for RCA PCI. When using the JL 3.5 catheter for RCA PCI, heart function, CTO, and tortuosity should be considered.
