“…Virtual reality simulation has evolved to allow incorporation of patient-specific computed tomography (CT) and magnetic resonance Digital Imaging and Communications in Medicine data into computer-based simulation devices such as the ANGIO Mentor (Simbionix, Airport City, Israel), facilitating case simulations based on real anatomy and procedure-specific rehearsals. 9,10 Threedimensional reconstructions of three real patients' cases, each representing a different level of anatomic complexity 8 as proposed in the anatomic scoring system developed by Macdonald et al, 7 were created using Simbionix PROcedure Rehearsal Studio software (Simbionix USA Corp, Cleveland, Ohio). The anatomic scoring system was developed using a survey and describes 12 different anatomic features including arch configuration, target vessel and tortuosity, and vessel calcification.…”

Objective: Video motion analysis (VMA) uses fluoroscopic sequences to derive information on catheter and guidewire movement and is able to calculate two-dimensional catheter tip path length (PL) on the basis of frame-by-frame pixel coordinates. The objective of this study was to evaluate the effect of anatomic complexity on the efficiency of completion of defined stages of simulated carotid artery stenting as measured by VMA.Methods: Twenty interventionists each performed a standardized easy, medium, and difficult carotid artery stenting case in random order on an ANGIO Mentor (Simbionix, Airport City, Israel) simulator. Videos of all procedures were analyzed using VMA software, and performance was expressed in terms of two-dimensional guidewire tip trajectory distance (PL). Comparisons of PL were used to identify differences in cannulation performance of the participants between the three cases of varying difficulty. The procedure was subdivided into four procedural phases: arch navigation, common carotid artery (CCA) cannulation, external carotid manipulation, and carotid lesion crossing. Comparisons of PL were used to identify differences in performance between the three cases of varying difficulty for each of the procedural phases.Results: There were significant differences in PL in relation to anatomic complexity, with a stepwise increase in PL from easy to difficult cases: easy, median of 5000 pixels (interquartile range, 4075-5403 pixels); intermediate, 9059 (5974-14,553) pixels; difficult, 17,373 (11,495-26,594) pixels (P < .001). Similarly, during CCA cannulation, there was a stepwise increase in PL from easy to difficult cases: easy, 749 (603-1403) pixels; intermediate, 3274 (1544-8142) pixels; difficult, 8845 (5954-15,768) pixels (P < .001). There were no observed differences across the groups of anatomic difficulty for the phases of arch navigation, external carotid manipulation, and carotid lesion crossing.Conclusions: Increasing anatomic complexity leads to significant increases in PL of endovascular tools, in particular during CCA cannulation. This increase in tool movement may have a bearing on clinical outcome.

“…39e43 Reports of using specialists as novices are, however, few. 35,44 The novice group in this study was comprised of consultants in radiology or vascular surgery with endovascular experience, ensuring a high baseline capability leading to a stricter pass/fail standard than if "true beginners" were used. Future implications EVAR, and planning and sizing, has traditionally been taught through the classical mastereapprentice approach without a predefined criterion for competency.…”
