Simulative operation on congenital heart disease using rubber-like urethane stereolithographic biomodels based on 3D datasets of multislice computed tomography☆

Abstract

Stereolithographic biomodelling is a promising technique for the preoperative practice and simulation of individual surgery. This technique would be useful in the planning of novel and innovative surgical procedures of congenital heart disease.

3D heart model printing for preparation of percutaneous structural interventions: description of the technology and case report

“…The technique of percutaneous mitral annuloplasty described above is still in the early stages of development, and therefore no comparisons to procedures done without the use of 3D models for planning have been performed. Currently, 3D printers are just becoming widely available at more affordable cost, and the use of 3D printed models in medicine is expected to rapidly increase [14][15][16]. CONCLUsIONs 3D heart printing may be a helpful tool for percutaneous structural interventions for facilitating preoperative planning, adjustment of procedural tools, and intraoperative supervision of the target structures.…”

“…In the paper by Jacobs et al [15], RP models were used to plan the resection of an LV aneurysm and right ventricular tumour. In another study, heart models made from a rubber-like urethane allowed simulation of a surgical operation [16].…”

Rapid Prototyping for Training Purposes in Cardiovascular Surgery

“…They are particularly useful to visualize patient's heart with complex structural problems, such as congenital defects and aneurysms (Kellenberger, Yoo et al 2007;Ou, Celermajer et al 2007;Spevak, Johnson et al 2008). However, incongruities between real anatomical structures and interpretation of virtual reconstructed threedimensional (3D) images still remain (Shiraishi, Yamagishi et al 2010). This drives surgeons to realize solid replicas of hearts with structural defects, which would convey better and more tangible information about spatial relationships between heart structures.…”

“…The model was used for the development of new endovascular techniques for repair of abdominal aortic aneurysm (Lermusiaux, Leroux et al 2001). Shiraishi et al used ultraviolet laser beam to polymerize a selectively photosensitive polymeric liquid plastic solution to produce models used for simulative operations on congenital heart disease (Shiraishi, Yamagishi et al 2010) Other than Stereolithography there are other rapid prototyping systems such as Laser Sintering methods, which are based on small particles of metal, plastic or glass that are fused by a high power laser. As well, there is Fused Deposition methods that extrude small beads of fused thermoplastic materials that immediately attach to the below layer.…”

Three-Dimensional Printing in Cardiovascular Disease: Verification of Diagnostic Accuracy of 3D Printed Models

“…[1][2][3][4][5][6][7][8][9] Furthermore, 3D printed realistic models have been shown to play an important role in pre-surgical planning and simulation of complex cardiovascular disease, in both adult and pediatric patients through clear illustration of cardiac pathologies and facilitation of the simulation. [13][14][15][16][17] Before 3D printed models are recommended for routine clinical applications, it is important to ensure the accuracy of 3D printed models. This is especially important for dealing with cardiovascular disease due to the complexity of cardiovascular anatomy and a variety of cardiovascular diseases, which requires high precision of 3D printed models.…”
