AS-134 Radiation Doses to Patient in Coronary Interventions in a Hospital in Thailand

Bi-plane and single plane angiography: a study to compare contrast usage and radiation doses for adult cardiac patients in diagnostic studies

“…Radiation exposure has cumulative stochastic adverse effects including cancer risks 1,4,7 and minimising the radiation exposure of patients and staff is a high priority in angiography procedures. 1,2,[4][5][6][7] Bi-plane angiography can be beneficial in many other types of cardiac procedures, including electrophysiology, percutaneous coronary intervention of complex lesions, particularly chronic total occlusions and also structural cardiac intervention, and complex procedures. 15 However, for patients with no identified renal impairment this study demonstrates that for diagnostic coronary angiography, it may be preferable to perform diagnostic angiogram studies in single-plane mode to reduce the overall radiation dose to the patient and staff.…”

“…Other variables studied in the literature which are not included in this study are clinician experience 4,6 and procedural complexity (measured in number of catheters used). 2,4,7 There were a variety of users between rooms 1 and 2 over the duration of the study, with varying amounts of experience. Unfortunately, no specific data were available to take different users into account on this study.…”
