Abstract

Percutaneous coronary interventions (PCI) of coronary chronic total occlusions (CTO) increase the risk of high radiation exposure for both the patient and the cardiologist. This study evaluated the maximum dose to the patients’ skin (MSD) and the exposure of the cardiologists during CTO-PCI. Moreover, the efficiency of radioprotective drapes to reduce cardiologist exposure was assessed. Patient dose was measured during 31 procedures; dose to the cardiologist’s extremities were measured during 65 procedures, among which 31 were performed with radioprotective drapes. The MSD was high (median: 1254 mGy; max: 6528 mGy), and higher than 2 Gy for 33% of the patients. The dose to the cardiologists’ extremities per procedure was also of concern (median: 25–465 μSv), particularly to the left eye (median: 68 μSv; max: 187 μSv). Radioprotective drapes reduced the exposure to physician’s upper limbs and eyes; especially to the left side (from −28 to −49%).
