Introduction: Detailed data stored by an ablation mapping system may be a valuable adjunctive training tool. This study was undertaken to assess whether procedural data from a cloud-based smart storage and data analytics system reflects differences between procedures involving fellows at different training stages. Methods: Data from atrial ablations involving a fellow in the first 3 months of year 1 (Y1) or year 2 (Y2) of an EP fellowship program were compared. Results: Mean contact force, catheter stability, ablation index and time between consecutive lesions were similar between Y2 vs. Y1. Y2 fellows performed 92.5% vs. 84.8% of cavotricuspid isthmus (CTI) lesions (P=0.4760), 67.5% vs. 61.8% of left pulmonary vein (PV) lesions (P=0.6795), and 72.1% vs. 63.4% of right PV lesions (P=0.5258) compared to Y1 fellows. Y2 fellows completed independent CTI isolation in 88.2% vs. 52.9% of cases compared to Y1 fellows (P=0.0570). In the 31 procedures where both PV and CTI ablations were performed, Y2 fellows completed the full procedure independently more often than Y1 fellows (40.0% vs. 6.3%, P=0.0373). Y2 fellows also had higher rates of independently achieving first pass PV isolation (17.4% vs. 0.0%, P=0.0497). Conclusion: Analysis of procedural data from a cloud-based smart storage system demonstrates that under careful supervision, procedural parameters at a lesion level, attainment of clinical endpoints and procedural safety are not affected by level of experience of trainee involved. Procedural data demonstrates increasing independence with progression through training and may be a valuable adjunct to training, allowing monitoring of technical skill development.
