Abstract Objective To investigate the feasibility and safety of using a single Ikari guiding catheter for transradial coronary angiography(CAG) and percutaneous coronary intervention(PCI) in patients with ST elevation myocardial infarc-tion (STEMI). Methods Patients with STEMI underwent emergent CAG and primary PCI via a single Ikari guiding catheter (Ikari group, n=56) or underwent CAG via Tiger catheter and primary PCI via guiding catheters (control group, n=63). Catheterization- to- angiography time,angiographic time, door- to- balloon (DTB) time, cathlab door- to- bal oon (CTB) time, procedure time and fluoroscopy time were analyzed. Results Radial artery cannulation was successful in al patients. There was no significant difference between two groups in catheterization- to- angiography time and angio-graphic time(P>0.05). Contrast consumption, DTB time, CTB time, procedure time and fluoroscopy time were significantly lower in Ikari group than in control group (P<0.01 or 0.05). Conclusion A single Ikari guiding catheter is feasible and safe for CAG and Primary PCI in patients with STEMI, which may shorten DTB time, CTB time, procedure time and fluo-roscopy time and reduce contrast consumption.
