Abstract

Radial artery (RA) intima–media thickness (IMT) could be used to study short- and long-term structural vascular adaptation following transradial cardiac catheterization. We aimed at assessing the reliability and reproducibility of RA-IMT measurement. Using high-resolution ultrasound, we studied RA-IMT in 17 patients, who underwent transradial catheterization via the right RA 1 to 12 months before. Radial artery intima–media thickness was measured in both arms, with the left RA as control. Repeated measurements were performed by 2 examiners and offline analyses were performed by independent blinded interpreters. Radial artery intima–media thickness was highly reliable with an interclass correlation coefficient (ICC) of 0.911 [0.870-0.939], a high examiner (ICCexaminer 0.910 [0.883-0.931]), and interpreter agreement (ICCinterpreter 0.963 [0.954-0.971]). Intima–media thickness at the radial access site was significantly increased compared with the contralateral RA (0.30 ± 0.056 vs 0.41 ± 0.055 mm, P < .00001). Radial artery intima–media thickness can be measured reliably using high-resolution ultrasound. Initial data suggest that transradial catheterization leads to long-term structural adaption processes.
