Use of 3D Printing in Preoperative Planning and Training for Aortic Endovascular Repair and Aortic Valve Disease

Abstract

IntroductionThree-dimensional (3D) printing has become an affordable tool for assisting heart surgeons in the aorta endovascular field, both in surgical planning, education and training of residents and students. This technique permits the construction of physical prototypes from conventional medical images by converting the anatomical information into computer aided design (CAD) files.ObjectiveTo present the 3D printing feature on developing prototypes leading to improved aortic endovascular surgical planning, as well as transcatheter aortic valve implantation, and mainly enabling training of the surgical procedure to be performed on patient's specific condition.MethodsSix 3D printed real scale prototypes were built representing different aortic diseases, taken from real patients, to simulate the correction of the disease with endoprosthesis deployment.ResultsIn the hybrid room, the 3D prototypes were examined under fluoroscopy, making it possible to obtain images that clearly delimited the walls of the aorta and its details. The endovascular simulation was then able to be performed, by correctly positioning the endoprosthesis, followed by its deployment.ConclusionThe 3D printing allowed the construction of aortic diseases realistic prototypes, offering a 3D view from the two-dimensional image of computed tomography (CT) angiography, allowing better surgical planning and surgeon training in the specific case beforehand.

There Is a Great Future in Plastics: Personalized Approach to the Management of Hilar Cholangiocarcinoma Using a 3-D-Printed Liver Model

“…In recent years, 3-D printing technology has become more available to a broader audience due to the rapid growth of commercial 3-D printers and the growing experience with this technology (2). Use of 3-D printed models has been proposed in medicine as a useful tool in the fields of education, surgical training simulation, patient-doctor communication, diagnosis, and pathological classification (3)(4)(5). More specifically, 3-D printing facilitates the creation of accurate anatomical models in relatively simply, easing the planning of complex surgical procedures (6)(7)(8).…”

A scoping review to identify competencies for transcatheter cardiovascular procedures

“…The earliest identified sources of evidence were published in 2006 (Table 1). [27][28][29][30][31][32][33][34][35][36][37][38][39][40]42,[44][45][46][47][48][49] Since then, there has been a steady, although nonlinear, increase in the number of publications, particularly from 2016 to 2020, during which 60.6% (n ¼ 20) of identified records were published (Figure 3). Publication types consisted mainly of comparative studies (30.3%; n ¼ 10) and societal statements (24.2%; n ¼ 8) with a smaller proportion of surveys and opinion articles (both 15.2%; n ¼ 5).…”

3D Printing of Physical Organ Models: Recent Developments and Challenges

“…Cardiovascular field is one of the most common application fields of medical 3D printing. [ 52 ] 3D printing and bioprinting technologies provide important help for the treatment of congenital heart disease, [ 119 , 120 , 121 ] aortic aneurysm, [ 122 , 123 ] cardiac tumor [ 124 ] and other cardiovascular diseases, and have been introduced comprehensively in some studies. [ 125 , 126 ] As far as organ models are concerned, the common ones are the models of complete heart or parts of it, [ 4 ] as well as the models for some vascular diseases.…”
