Abstract

To assess the impact of an assistant on the technical skills of the operator performing superficial femoral artery (SFA) angioplasty on the vascular intervention simulation trainer (VIST) simulator. Eight experts performed 2 SFA angioplasties each on the VIST. Four experts had an assistant available. Experts' video recordings were blindly evaluated using global and procedural rating scales. Experts with assistants scored higher than the controls in the first: global rating scale (47.8 ± 0.5 vs 33.5 ± 5.1, P = .01); procedural rating scale (94.3 ± 2.2 vs 89 ± 2.5, P = .02) and the second procedure: global rating scale (47.8 ± 0.5 vs 38 ± 7, P = .03); procedural rating scale (95.3 ± 0.5 vs 89.5 ± 2.4, P = .02). The presence of an assistant had a positive influence on the technical skills of the operator performing SFA angioplasty on the VIST simulator.
