Abstract [en]

Background. Although transradial access (TRA) is being increasingly used in interventional cardiology, there are concerns about a possible increase in radiation exposure (RE) as compared to transfemoral access (TFA). Methods. In this retrospective study, we aimed to compare RE during coronary angiography and percutaneous coronary intervention (PCI) according to the vascular access route (TRA vs TFA). We included all procedures performed in our laboratory, in which RE data (dose area product, cGy.cm(2)) were available, from May 2009 to May 2013. Both multiple linear regression analysis and propensity score matching were performed in order to compare RE between TRA and TFA after adjusting for clinical and procedural confounders. Results. DAP values were available for 1396 procedures; TRA rate was 82.6%. TRA patients were younger, less frequently female, and had higher body mass index as compared to TFA patients; the rates of PCI, ad hoc PCI, bypass angiography, thrombus aspiration, and primary angioplasty, as well as the number of stents implanted, fluoroscopy time, and contrast dose were significantly higher in TFA. Median DAP value was significantly higher in TFA than in TRA (9670 cGy.cm(2) vs 7635 cGy.cm(2); P<.01). After adjusting for clinical and procedural confounders, vascular access was not found to be an independent predictor of RE at multiple regression analysis; this was also confirmed by stratified comparison of DAP values by quintiles of propensity score. Conclusion. After adjusting for clinical and procedural confounders, TRA was not found to be associated with increased RE as compared to TFA in an experienced TRA center.
