Kallinikou Z, Puricel SG, Ryckx N, et al. Radiation Exposure of the Operator During Coronary Interventions (from the RADIO Study). Am J Cardiol. 2016 Jul 15;188(2):188-194.

We sought to compare operator radiation exposure during procedures using right femoral access (RFA), right radial access (RRA), and left radial access (LRA) during coronary angiography (CA) and percutaneous coronary intervention (PCI). There were no significant differences in DAP among the 3 access sites. FT was similar for the 3 groups (RFA 7 ± 7, RRA 5 ± 5, LRA 6 ± 5 minutes, RFA vs RRA: p = 1, RFA vs LRA: p = 0.16, RRA vs LRA: p = 0.52).
