Effectiveness of the implementation of a simple radiation reduction protocol in the catheterization laboratory

Abstract Background and purpose A reduction in radiation doses at the catheterization laboratory, maintaining the quality of procedures is essential. Our objective was to analyze the results of a simple radiation reduction protocol at a high-volume interventional cardiology unit. Methods We analyzed 1160 consecutive procedures: 580 performed before the implementation of the protocol and 580 after it. The protocol consisted in: the reduction of the number of ventriculographies and aortographies, the optimization of the collimation and the geometry of the X ray tube-patient-receptor, the use of low dose-rate fluoroscopy and the reduction of the number of cine sequences using the software “last fluoroscopy hold”. Results There were no significant differences in clinical baseline features or in the procedural characteristics with the exception of a higher percentage of radial approach (30.7% vs 69.6%; p  2 ; p  Conclusions With the implementation of a simple radiation reduction protocol, a 57% reduction of dose–area product was observed without a reduction in the quality or the complexity of procedures.
