title: Radiation doses in a newly founded Interventional Cardiology department.
abstract: Coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) radiation doses were investigated in a recently founded Interventional Cardiology (IC) department. The study includes 336 procedures (177 CAs and 159 PTCAs) carried out with a Philips digital flat detector monoplane system. Patient dose was measured in terms of kerma-area product (KAP) and cumulative dose. Using appropriate conversion factors, peak skin dose (PSD) and effective dose (E) were estimated. Median values of KAP (Gy cm(2)), PSD (mGy) and E (mSv) were: 34 478 and 6.1, respectively for CA and 80 885 and 14.4 for PTCA, within European and international reference levels. Only 1.5 % of patients received radiation dose over the 2 Gy threshold (PTCA procedures) for deterministic effects and none reported any skin effect. Radiation doses were within international standards and comparable with other radiological examinations. The percentage of the high-risk patients for radiation skin effects is extremely low.
