Introduction: Fluoroscopic real-time visualization of the catheters may be needed during electrophysiological studies and catheter ablations. Radiation can cause health damage in a stochastic way as well, the cause-effect relations cannot always be determined. Lately serious efforts have been done to reduce the fluoroscopy time and dose, as required by the ALARA (as low as reasonably achievable) concept. In the literature, the radiation time and radiation dose vary among different clinical centers.
Aim: Our aim was to compare the mean fluoroscopic time used during electrophysiological procedures nowadays and before 2014.
Method: We collected and compared the fluoroscopy times registered between 06 October 2016 and 10 January 2017. and 18 October 2013 and 16 December 2013 at the Heart and Vascular Center of Semmelweis University.
Results: We observed a significantly lower mean fluoroscopy time in the case of atrial fibrillation, atrial flutter, AVRT, AVNRT, PVC ablation and electophysiological studies compared to the procedures before 2014 (5,57 vs. 13,9 min p<0,0001; 2,24 vs. 6,41 min p=0,0078; 3,32 vs. 7,74 min p=0,0211; 1,7 vs. 5,16 min p<0,0001; 2,17 vs. 5,83 min p=0,0006; 0,68 vs. 1,43 min p=0,0378).
Conclusion: Over three years with the use of ALARA priciples we obtained a significantly lower mean fluoroscopy time during electrophysiologiacal studies and catheter ablations, which is impressive compared with the international literature.
