Nicolette S. Birbara, James Otton, Nalini Pather (School of Medical Sciences, Medicine)Introduction: Multiple surgical and interventional techniques are available to treat mitral valve (MV) disease. These treatments must be carefully adapted to patient-specific anatomy and pathology. While three-dimensional (3D) echocardiography has traditionally been used for mitral valve repair, cardiac CT provides several advantages, particularly with regards to 3D assessment and modelling. This study aimed to assess the value of 3D printing for MV surgical and interventional planning. Methods: Gated cardiac computed tomography (CT) and 3D transesophageal (TEE) echocardiography imaging data of four MV disease patients was used to produce patient-specific 3D printed models. A variety of 3D printing machines and methods were used including rigid, flexible and multi-material prints. Forty cardiac health professionals (CHPs) were surveyed on the perceived value of 3D models for surgical planning, following their evaluation of the 3D printed models for each patient. Results: Patient-specific 3D printed models were considered useful for surgical planning by CHPs, and were seen to provide a different perspective and additional information to imaging. Most CHPs surveyed indicated that
