Figure 6: Development of the median distribution of fluoroscopy times of all participants (n=11) in three training rounds
The median fluoroscopy time could be reduced from 218 seconds in the beginning to 104 seconds at the end of the third training round. Attention needs to be paid to the fact that the 1st and 2nd round were performed on the model of a healthy heart whereas the same steps were performed on a model with valvular pulmonary stenosis in the 3rd round. Thus, the last round contained an additional difficulty because the wire and catheter had to be steered past the obstacle of the pulmonary valve stenosis. Nevertheless, a significant difference, i.e., decrease of fluoroscopy time, among these three rounds could be shown. (Sign test: *p<0,05, ***p<0,001).
