3D PRINTING CONFERENCE INNOVATION,
MODELLING, APPLICATION & IMPLEMENTATION
Objectives: To print 3D models of children hearts affected
with complex congenital heart defects. To assess the accuracy
of 3D printing by comparison of printed heart models with in
vivo findings described by surgeons. To investigate the ideal
form of printing in different types of congenital heart defects
and to analyse the potential benefits of printed heart models
use in surgical planning in pediatric cardiology.
Methods: Between December 2014 and March 2017,
we printed 20 heart models for patients with congenital
hearts defects. Initial data of heart anatomy came from CT
images. A Bland-Altman analysis was used to evaluate the
accuracy of 3D printing by comparing of cardiovascular
proportions between models and in vivo surgical findings.
The contribution of 3D printed heart models use for surgical
planning improvement was analysed in all 20 patients.
Results: We successfully printed heart models in all 20
patients. The Bland-Altman analysis confirmed high accuracy
of 3D heart printing. We printed the “cast types” of models,
representing the “real” lumens of cardiovascular lumens, in
16 patients. The “meat-like types” of models, representing
the “real” walls of cardiac chambers, were printed in specific
demand to image the real size of defects in ventricular
septum, in 4 patients. All heart models provided us valuable
preoperative information of congenital heart defects 3D
anatomy.
Conclusions: 3D printers can be effectively used for exact
printing of heart models of children suffering from complex
congenital heart defects. Different types of models can be
printed depending on indication. The use of printed heart
models have a potential to improve preoperative planning in
these patients.
Speaker Biography
Peter Olejnik MD, PhD is clinical deputy chief of Pediatric Cardiology Clinic of Comenius
University Medical School in Bratislava. He trained in pediatrics at the Slovak Medical
University of Bratislava and pediatric cardiology at the Comenius University of
Bratislava, where he also obtained academic title “PhD”. He has been practicing since
2004, all 13 years in Bratislava, Slovakia, at the Department of Pediatric Cardiology of
National Institute of Cardiovascular Diseases of Slovak Republic. His practise specializes
in the care of children with congenital heart defects and interests include modern
imaging methods in pediatric cardiology, I.e. computed tomography imaging and
magnetic resonance imaging. He is focused on 3D printed heart models for children
suffering with complex congenital heart defects.
