Purposes for inclusion of various specialties within clinician group

Party	Purpose for inclusion in feedback	How would three-dimensional (3D) modelling be useful to this party?
Researcher	Strong cardiovascular background but likely limited experience with cardiac imaging and congenital heart disease.	Appreciation of anatomy across different congenital coronary artery diseases; potential use of models in future research.
Cardiac surgeon	Experienced with cardiac anatomy, pathology and imaging; specific focus on potential use of models for preoperative assessment.	Understanding specific visuospatial anatomy abnormality; preoperative planning and practice.
Radiologist/imaging expert	Extremely experienced with imaging; assessing whether 3D models improve/complement appreciation from CT alone.	Visuospatial appreciation of abnormality in addition to what they see on scans.
Cardiologist	Experienced with cardiac anatomy, pathology and imaging; assessing whether models can improve/complement understanding.	Use for complex cases with difficult coronary anatomy; support management decisions based on measurable dimensions.
