“…The 3D model clearly depicted very complex spatial relationships among the hypoplastic right ventricle outflow tract, the central shunt, cardiac surgeons and cardiologists, printed heart models map out an exact, real 3D cardiovascular anatomy. The use of 3D models enhances physicians' understanding of the complex anatomy, so these models are valuable for perioperative planning and intraoperative orientation [9][10][11]. Because of this, the use of models can avoid improvisation, save intraoperative time, and improve the chances of a better outcome [2].…”

A b s t r a c t Background and aim:To evaluate the accuracy of the three-dimensional (3D) printing of cardiovascular structures. To explore whether utilisation of 3D printed heart replicas can improve surgical and catheter interventional planning in patients with complex congenital heart defects. Methods:Between December 2014 and November 2015 we fabricated eight cardiovascular models based on computed tomography data in patients with complex spatial anatomical relationships of cardiovascular structures. A Bland-Altman analysis was used to assess the accuracy of 3D printing by comparing dimension measurements at analogous anatomical locations between the printed models and digital imagery data, as well as between printed models and in vivo surgical findings. The contribution of 3D printed heart models for perioperative planning improvement was evaluated in the four most representative patients. Results:Bland-Altman analysis confirmed the high accuracy of 3D cardiovascular printing. Each printed model offered an improved spatial anatomical orientation of cardiovascular structures.Conclusions: Current 3D printers can produce authentic copies of patients` cardiovascular systems from computed tomography data. The use of 3D printed models can facilitate surgical or catheter interventional procedures in patients with complex congenital heart defects due to better preoperative planning and intraoperative orientation.

“…13 Up to now, most proposals for heart operation applications linked to the use of rapid prototyping technologies in combination with medical imaging information was designed for preoperative studies and for planning surgical operations. 1,15,22,30,40 However, this combination of technologies may also turn out to be decisive in promoting their industrial expansion. This has become apparent in recent years in areas such as oral and maxillofacial surgery.…”

Development of Personalized Annuloplasty Rings: Combination of CT Images and CAD-CAM Tools

Although the use of personalized annuloplasty rings manufactured for each patient according to the size and morphology of their valve complex could be beneficial for the treatment of mitral insufficiency, this possibility has been limited for reasons of time-lines and costs as well as for design and manufacturing difficulties, as has been the case with other personalized implant and prosthetic developments. However, the present quality of medical image capture equipment together with the benefits to be had from computer-aided design and manufacturing technologies (CAD-CAM) and the capabilities furnished by rapid prototyping technologies, present new opportunities for a personalized response to the development of implants and prostheses, the social impact of which could turn out to be highly positive. This paper sets out a personalized development of an annuloplasty ring based on the combined use of information from medical imaging, from CAD-CAM design programs and prototype manufacture using rapid prototyping technologies.
