AIM: To evaluate patient radiation exposure for Diagnostic Coronary Angiography (DCA) and Percutaneous Cardiac Intervention (PCI) performed by different operators.
METHODS AND RESULTS: Retrospective (n = 160) and prospective (n = 62) data for DCA (n = 179) and PCI (n = 43) examinations performed by interventional cardiologists (n = 3) using the same imaging equipment were reviewed. The operator with consistently low diagnostic reference levels (DRLs) was interviewed for their personal perceptions upon operator training. Retrospective Median [IQR] DAP was 18.8 [11.8-31.6] and 50.7 [35.3-85.6] Gy.cm2 for DCA and PCI, respectively. Prospective Median [IQR] DAP for DCA and PCI was 7.9 [5.2-10.6] and 15.9 [10.0-17.7] Gy.cm2, respectively. DRLs were within Irish and European DRLs; however, significant inter-operator variability (p < .001) was identified.
CONCLUSION: Radiation exposure in Interventional cardiology is highly operator dependent; further research is warranted in standardization of operator training with evolving technologies.
