Surgical correction of mitral valve (MV) disease requires detailed knowledge of patient-specific MV anatomy. While the use of three-dimensional (3D) modeling and printing in MV assessment has undergone early clinical evaluation, the precision and usefulness of this technology needs validation. This study aimed to validate 3D modeling and printing technology for MV surgical planning. A prototype method for MV 3 D modelling and printing from computed tomography (CT) scans was developed using the Mimics Innovation Suite software package (Materialise NV, Leuven, Belgium). MV models were printed using four 3D printing methods and validated using an iterative closest point algorithm to assess precision. Cardiac CT and 3D echocardiography imaging data of four MV disease patients was used to produce patient-specific 3D printed models, and 12 clinicians were surveyed on the perceived value of 3D models for preoperative planning. A prototype method for MV 3D modelling and printing was developed from CT scans of a plastinated human heart. The prototype demonstrated submillimeter precision for all four 3 D printing methods used. A Mann-Whitney U test showed a significant difference (P < 0.05) in precision between these methods, with stereolithography being the most precise and polyjet being the least precise. Patient-specific 3D printed models, particularly in flexible print material, were considered useful for preoperative planning by clinicians. This study suggests that 3D modelling and printing using patient-specific data could serve as a useful clinical tool, with enormous potential for both patient morbidity and the future of surgical training.

Conference13th Annual Meeting of the Australian and New Zealand Association of Clinical Anatomists - ANZACA 2016
Abbreviated titleArtful Anatomy
OtherThe ANU Medical School in Canberra, Australia, welcomed 102 attendees from 10 countries to the 13th Annual ANZACA Meeting. A range of activities were organized relevant to the conference’s theme“Artful Anatomy,” including keynote presentations and workshops delivered by Dr Sarah Simblet (Ruskin School of Art at the University of Oxford, UK); and an Art and Anatomy Symposium delivered by ANZACA members from four different Australian and New Zealand institutions who shared the diverse approaches by which they integrate anatomy and art. Attendees were invited to an “Anatomy and Art Tour” at the National Gallery of Australia followed by a Welcome Cocktail Reception in the beautiful National Gallery of Australia Sculpture Garden. An exhibition of artistic works exploring human anatomy, created by ANU students and Vice Chancellor’s College Artist Fellows, was on display during the conference. Additional keynote presentations, and workshops were delivered by Prof Richard Drake(Cleveland Clinic Lerner College of Medicine of Case Western Reserve University, Cleveland, OH), and Assoc Prof Beth Beckmann (Centre of Higher Education, Learning and Teaching, ANU, Canberra, Australia).The conference program was composed of 24 oral and 41 poster presentations. In addition, ANZACA members contributed to a “Sharing Educational Innovations – Rapid Fire” session that provided an opportunity to share and discuss elements of their educational practice.The Conference Dinner was held at the National Museum of Australia overlooking Lake Burley Griffin. The conference organisers were sup-ported by a capable team of volunteer ANU Medical School students and alumni, who ensured that the conference ran smoothly.
