The Intervention Centre at Oslo University Hospital have been focusing on visualization of preoperative models and surgery planning using the Microsoft HoloLens. The TruHeart research project builds on the completed HoloViz project and focuses on preoperative planning using the TruHeart application for HoloLens. 

In the area of cardiothoracic surgery, visualization through HoloLens provides easier, cheaper and faster access to 3D experience, making it applicable to a lot of clinical scenarios. For complex congenital cardiac anomalies like Pulmonary Atresia with Ventricular Septal Defect and Major Aortopulmonary Collateral Arteries (PA/VSD/MAPCAS) and complex Double-outlet right ventricle (DORV) in paediatric heart, it is essential to understand the exact 3D anatomy before surgery. This is currently achieved through 3D printed models that cost 1500 euros per print, on which a cut is made to see the inner anatomy. Cutting in a hologram makes it cheaper and easier to study the inner anatomy.

Main goal

The main objective of the TruHeart project is to create a 3D planning tool for medical professionals to study the inner anatomy of the heart, manipulate the 3D model of the organ, and to conduct necessary measurements before treatment to find the optimal treatment method. The functionality of the application allows for expanding the use of TruHeart to other cardiac anomalies.
