Abuzid W, Abunassar J, Leis JA, et al. Radiation Safety In The Cardiac Catheterization Lab: A Time Series Quality Improvement Initiative. Cardiovasc Revasc Med. Jul-Aug 2017;18(5S1):S22-S26.

This study sought to reduce the frequency of radiation exposure, for PCI procedures, above 1.5Gy in labs utilizing a Phillips system at our local institution by 40%, over a 12-month period. There was a significant reduction (91%, p<0.05) in the frequency of radiation exposure above 1.5Gy after utilizing a novel software (AlluraClarity©) in a new Phillips lab. Process measures of use of collimation (95.0% to 98.0%), use of magnification (20.0% to 14.0%) and completion of online modules (62%) helped track implementation.

Abdelaal E, Plourde G, MacHaalany J, et al. Effectiveness of Low Rate Fluoroscopy at Reducing Operator and Patient Radiation Dose During Transradial Coronary Angiography and Interventions. JACC Cardiovasc Interv. 2014 May;7(5):567-74.

In this study, we aimed to evaluate the efficacy of low rate fluoroscopy at 7.5 frames/s (FPS) compared with conventional 15 FPS, in reducing operator and patient radiation dose during TRA diagnostic coronary angiography (DCA) and percutaneous coronary interventions (PCI).

Aarsnes A, Dahle G, Fosse E, et al. EVALUATION OF OCCUPATIONAL RADIATION DOSE IN TRANSCATHETER AORTIC VALVE IMPLANTATION. Radiat Prot Dosimetry. 2018 Apr 1;179(1):9-17.

In transcatheter aortic valve implantation, the operators’ positions and use of radiation shielding are particularly related to the entry choice on the patient’s heart. This study evaluates how occupational doses depend on operator positioning during transfemoral and transaortal access. Occupational dosimetric readings were collected with electronic dosemeters on two cardiothoracic surgeons and one cardiologist during 31 procedures. The findings were significantly higher body doses and eye lens doses to the surgeons during transaortal access compared to transfemoral access.
