Assessment of Local Dose Reference Values for Recanalization of Chronic Total Occlusions and Other Occlusions in a High-Volume Catheterization Center

A retrospective study of radiation dose measurements comparing different cath lab X‐ray systems in a sample population of patients undergoing percutaneous coronary intervention for chronic total occlusions

“…Maccia et al determined local DRL for CTO PCI in their large volume center. Irrespective of procedural approach, mean DAP was 25,200 cGycm 2 ; 75th percentile DAP was 35,000 cGycm 2 . Therefore, despite the relatively high DAP values of the older systems in our study, they are still lower than what is considered to be an acceptable radiation dose.…”

Reduction of radiation exposure during complex interventions for chronic total coronary occlusions: Implementing low dose radiation protocols without affecting procedural success rates

“…In a European study of recent procedures in 2013–2014, the average AK for CTO PCI was in a similar range as the US reports with 4.0 Gy . The authors derived radiation reference limits for antegrade CTO procedures of 1.8 Gy and a FT of 22 min, and 6.9 Gy with a FT of 82 min for retrograde procedures.…”

Influence of novel X‐ray imaging technology on radiation exposure during chronic total occlusion procedures

“…A longitudinal study from 2006 to 2011 focusing on temporal trends in radiation for CTO procedures documented a decline of AK but still reported a rather high average of 4.7 Gy . In a recent European study from 2013 to 2014, the average AK for CTO‐PCI was in a similar range as the United States reports at 4.0 Gy . The authors derived radiation reference limits for antegrade CTO procedures of 1.8 Gy and an FT of 22 min and 6.9 Gy with an FT of 82 min for retrograde procedures.…”
