Lung transplantation is a well-established life-extending treatment for patients with CF and end-stage lung disease. The operative mortality is low and CF patients have a significant early survival benefit after lung transplantation. Satisfying long-term results can be achieved in this young and severely ill group of patients.

The Delphi methodology allowed for international consensus on a new procedure specific global rating scale for assessment of competence in EVAR. The resulting scale, EndoVascular Aortic Repair Assessment of Technical Expertise (EVARATE), represents key elements in the procedure. EVARATE constitutes an assessment tool for providing structured feedback to endovascular operators in training.

This paper presents the initial validity evidence for a novel procedure specific assessment tool, EVARATE, for operator competence in endovascular aortic repair investigated in a simulated setting. The assessment tool can be used to provide structured formative feedback to trainees.

This study presents a standardised and objective assessment tool of competence in vessel analysis and stent graft selection for endovascular aortic repair. This was supported by strong validity evidence with good internal consistency and discriminatory ability. The tool may be used to facilitate training and certification of future endovascular specialists.
