The element assisting CarnaLife Holo is 3D printing, which allows doctors, patients and other stakeholders to thoroughly understand each case.

The synergy of HoloLens glasses combined with 3D printing was first experienced by Polish doctors:

1. Balloon pulmonary angioplasty

Patient-specific models were developed for doctors from European Health Centre in Otwock. It was a first case in the world where balloon pulmonary angioplasty was assisted with 3D printing and augmented reality. Models of arteries were printed in 1:1 and 1:2 scale. Specific segments of vessels were distinguished by printing them in different colors to allow team of Prof. Kurzyna very precise visualization and catheter navigation.

Models were printed with polylactic acid on a desktop FDM printer.

2. Left atrial appendage occlusion

A series of personalized 3D-printed models were used in planning left atrial appendage occlusion in Krakow and Warsaw, Poland. They were created based on computed tomography images, routinely acquired when patients are qualified to this type of procedure. Printed heart parts – mainly left atrium with the appendage and connected vessels – allow doctors not only to evaluate the morphology of patient’s cardiac structures, but also to precisely plan the procedure, including choosing the proper device size.
