Wax cores were painted with six layers of elastic silicone and melted, yielding phantoms that were consecutively fixed in a mounting with and without a thoracic wall. Simulation included: proximal and distal aortic arch clamping, incision of its lesser curvature, extended end-to-end anastomosis with 7-0 suture. A head-mounted camera video recording enabled anastomosis time and mean one suture bite time evaluation. Leakage assessment was done by a water test.<\/jats:p><\/jats:sec><jats:sec id=\"S104795111900266X_as3\"><jats:title>Results:<\/jats:title><jats:p>Two residents performed nine simulations each. Last four runs were performed with thoracic wall attached. All phantoms performed well, enabling tissue-like handling and cutting, excellent suture retention, and satisfactory elasticity. Median anastomosis times were 22\u203233\u2033 and 24\u203247\u2033 for phantoms without and with thoracic wall (p = not significant (NS)). Median times needed to pass suture through one side of anastomosis and regrasp needle were, respectively, 9\u2033 and 13\u2033 (p &lt; 0.001). Median total number of leakages per phantom equalled 2 for both difficulty levels. There were no significant inter-resident differences in all assessed parameters.<\/jats:p><\/jats:sec><jats:sec id=\"S104795111900266X_as4\"><jats:title>Conclusions:<\/jats:title><jats:p>This medium-fidelity aortic coarctation repair trainer showed its feasibility in replication of major critical steps of the real operation.
