“We created a personalized model of the left ventricle, to simulate the implantation of prosthetic heart valves – printed using the 3DGence ONE printer”
Professor Zbigniew Religa’s Cardiac Surgery Development Foundation has been established in Zabrze in 1991, to introduce the latest methods and live-saving techniques for when the heart is compromised, into clinical practice. The Foundation also supports cardiac surgery and promotes health activities. They focus primarily on conducting and funding researches and innovations related to the treatment of heart disease, especially in medical, pharmaceutical, biological, mathematical and physical fields.
In order to save time and money, the Professor Zbigniew Religa’s Foundation uses a 3DGence ONE 3D printer, which allows them to prototype, develop and support new treatments.
Personalized (recreated from image data of a patient) model of a left ventricular, created to simulate the implantation of an artificial heart valve prosthesis in transcatheter mitral (TAVI) to a patient with need of high-risk surgery. The flexible, composite 3D model of the left ventricle is used during simulation of the operation process.
The model was cast from flexible silicone of mechanical properties, similar to those of the heart. The form was printed on 3DGence ONE printer with PLA filament.
Model manufacturing time:
- Segmentation of images obtained with CT and 3D model development – 7 days
- Form elements printout – two days
- Model casting – one day
- Finishing the model – 3 days
Benefits of using 3D printing technology
In cardiac surgery, creating personalized 3D printed models plays an important role in perioperative operations planning and simulating surgical operations for patients with a unique anatomy. Using a 3D printer is now the cheapest and quickest way to create models, which support treatment of cardiovascular diseases. The 3D models are widely used in treatment of congenital and acquired heart defects for patients with high operation risk and for supporting new medical treatments.
Thanks to the quick hotend exchange mechanism of 3DGence ONE, the components were printed with an accuracy of 0.1 mm.
