simulator training in interventional cardiology (ST) is an educational tool that is rapidly spreading worldwide. The purpose of this study was to evaluate the advantages of ST in improving skills of beginners in interventional cardiology procedures, through a short training cycle.

we conducted a before-and-after quasi-experimental evaluative study in the simulation center of the Faculty of Medicine in Sfax. We involved cardiology residents at the beginning of their training in interventional cardiology. All the participants attended a 4-hour training course on a Cathi^®, high-fidelity simulator, after giving their consent. The primary endpoint was a significant improvement in performance and competence scores before and after the course. The secondary endpoint was the reduction in irradiation time and the time of the procedure.

thirteen learners participated in our study. The performance score improved by a median of 216.12% (ISQ = 285%). This improvement was significantly greater for learners who had never had access to the catheterisation room. The performance score ranged from a median of 31 (ISQ=40.5) to a median of 120 (ISQ=19.7), (p=0.001). The competence score for coronary angiography improved significantly, from a median of 16 (ISQ=18) to a median of 70 (ISQ=6), (p=0.001). The competence score for angioplasty improved significantly from a median of 10 (ISQ=17) to a median of 50 (ISQ=13.7), p=0.001. Procedure time of coronary angiography and angioplasty were significantly shortened from 12 min (ISQ=2) to 7 min (ISQ=1) after the simulation cycle (p=0.001), and from a median of 19 min to a median of 17 min after simulation, p=0.002.

despite a short-time simulation training, our pilot study demonstrates a significant improvement in the learners´ skills and performance, as well as a reduction in the time taken to carry out procedures and irradiation. This could eventually increase the number of procedures carried out daily in our cathlab and limit radiation exposure of staff and patients, while ensuring that the learners receive adequate training.
