Background <p>The aim of this study was to compare the efficacy outcomes of the traditional Judkins left and right catheters with those of the recently introduced Tiger catheter in female participants aged 65 years and older who underwent transradial coronary angiography.</p> Methods <p>A cohort of 160 female patients aged 65 and older who were scheduled for coronary angiography (CAG) were divided into two groups according to the use of Tiger (<i>n</i> = 80) or Judkins (<i>n</i> = 80) catheters for radial angiography at a ratio of 1:1, respectively. We analyzed the effectiveness of the Tiger and Judkins catheters, the incidence of catheter failure, contrast volume, CAG time, fluoroscopy time, dose–area product (in mGy/cm²), and the occurrence of radial spasm.</p> Results <p>The Judkins catheter group had a significantly longer processing time than the Tiger catheter group, with an equivalent level of radiation exposure. The duration of fluoroscopy was longer, and the amount of contrast medium used was higher, but the frequency of radial spasm was not significantly different.</p> Conclusion <p>The present investigation revealed that implementation of Tiger catheters for geriatric individuals with elevated frailty and female patients with more narrow radial artery diameters was associated with decreased overall procedure duration, contrast volume utilization, and fluoroscopy duration.</p>
