What are the dose-area product and peak skin dose for patients undergoing coronary angiography and percutaneous coronary intervention?
Radiation doses during PCI are significantly higher than diagnostic CA, occasionally exceeding thresholds for skin erythema, highlighting the need for periodic monitoring.
PCI was associated with markedly higher radiation doses than coronary angiography, occasionally exceeding erythema thresholds; leaves open optimal monitoring strategies pending prospective data.
The objective of this study was to evaluate dose-area product (DAP) and peak skin dose (PSD) for coronary angiography (CA) and percutaneous coronary intervention (PCI). The DAP and PSD of 300 randomly selected patients who were referred to CA and/or PCI, over a period of 3 months were recorded and analyzed. The mean DAP of 32 Gy cm2 and mean PSD of 412 mGy for CA were lower than 118 Gy cm2 and 857 mGy, respectively, for PCI. The DAP range of 2-84 Gy cm2 for CA and 12-378 mGy for PCI were also established. The maximum value of PSD for PCI procedures reached above the 2 Gy threshold for erythema. However, these values are similar to those available in literature. Periodic surveys may be required to monitor and/or reduce radiation doses in coronary interventional procedures.
