Clinical and Procedural Characteristics Associated With Higher Radiation Exposure During Percutaneous Coronary Interventions and Coronary Angiography

Abstract

Background-We aim to study the clinical and procedural characteristics associated with higher radiation exposure in patients undergoing percutaneous coronary interventions (PCIs) and coronary angiography. .001) were associated with the highest radiation exposure. After adjusting for procedural complexity, radial access route was not associated with increased radiation exposure (β=1.00; CI, 0.98-1.03; P=0.67). Conclusions-In the largest study population to assess radiation exposure, we found that high body mass index, history of coronary artery bypass graft surgery, number of treated lesions, and chronic total occlusions were associated with the highest patient radiation exposure. Radial access site was not associated with higher radiation exposure when compared with femoral approach. (Circ Cardiovasc Interv. 2013;6:501-506.)

Rotational atherectomy through the radial artery is associated with similar procedural success when compared with the transfemoral route

“…The evidence for this remains controversial, and more recent studies have suggested that there is no difference in radiation exposure between radial and femoral cases, when performed by experienced radial operators [17]. Although fluoroscopy time and radiation dose were both numerically higher in the transradial group, we did not find a statistically significant difference in fluoroscopy time or radiation dose between the two groups.…”

Impact of Center Experience on Patient Radiation Exposure During Transradial Coronary Angiography and Percutaneous Intervention: A Patient‐Level, International, Collaborative, Multi‐Center Analysis

“…Furthermore, the predictors of radiation exposure remain far more complex than simply the access site alone. Indeed, recent analyses have suggested that increasing body mass index, history of coronary artery bypass grafting, increasing number of treated lesions, and chronic‐total occlusions were associated with increased radiation exposure . Others invoke patient sex, lesion complexity, lesion location, and the performing physician as also contributing to subsequent radiation exposure .…”

“…Accordingly, minimizing both patient and the catheterization staffs’ radiation exposure remains a priority. The TR approach is assumed to result in a higher radiation exposure than its TF equivalent, but this continues to be the subject of considerable debate . As the TR approach becomes more commonly adopted, so too do concerns over a subsequent risk of increased radiation exposure.…”

Value of Image Fusion in Coronary Angiography for the Detection of Coronary Artery Bypass Grafts

“…Coronary angiography in patients with CABG not only lasts longer, but also leads to higher irradiation and nephrotoxicity than coronary angiography in patients without CABG . In addition, the CABG population is certainly more fragile and at a higher risk of complications related to more comorbidities, such as polyvascular diseases, elderly, overweight, and kidney failure.…”
