To report methodology and first-year results of a new educational project called "Televascular Games", which took place during COVID-19 pandemic. Complex aneurysmal aortic disease was discussed during a 2-hour competition webinar, according to three modalities. 1) Planning case competition (PCC): 2-4 pre-operative Computed Tomography Angiography (CTA) scans of an already performed selected case were submitted for the competition. CTA-scans were anonymously uploaded, without any reference to the center or the surgeon who performed the case. The competitor had to prepare a presentation of how he/she would have diagnosed, sized, planned, treated and followed up the case, of the medical therapy and of the bail-out maneuvers. 2) Challenging case competition (CCC): the competitor elaborates a presentation of an already treated case concerning an aortic topic and discusses sizing, planning, treatment, possible bail-out maneuvers and obtained results. For the CCC and PCC, the competitors with the best score were pre-selected to present and discuss their plan during the webinars. 3) Quiz competition (QZ): 2-6 angio-CTA scans of already performed selected aortic cases were submitted for the competition. A quiz with multiple-choice questions was answered by the competitors. The top four competitors were selected for the webinars and then they discussed the cases during the webinar. Finally, at the end of the case-discussion, the effective case resolution and follow-up were shown. A final winner was voted via televoting, based on six pre-established criteria. The project was endorsed by different National and International Societies. Between October-2020 and December-2021, there were 12 Italian and 1 international webinars with overall 1695 participants (mean 130, range:86-177). Competitors were 54 (mean age 27, range 22-38 years). Two editions were CCCs, two QZs, and nine PCCs. The reliability of the inter-observer sizing of competitors was k=.43 and k=.62 for the proximal and distal sealing measurements respectively and very good (k =.88-.95) in the evaluation of orientation of the vessels, presence of angulations, calcifications and thrombus. The sizing discrepancy resulted in a significant variability of the planning (k=.45). The project ranked 9.6 in a "10-point" rating scale by all the participants and competitors. The formula of gaming and collegial discussion of aortic cases herein reported has proved valid and attractive during COVID-19 pandemic period. The variability of the results on sizing and planning suggested to confer with a second opinion especially for less experienced surgeons.
