Three-Dimensional Printing Applications in Percutaneous Structural Heart Interventions

Cardiovascular 3-dimensional printing refers to the fabrication of patients’ specific cardiac anatomic replicas based on volumetric imaging data sets obtained by echocardiography, computed tomography, or magnetic resonance imaging. It enables advanced visualization and enhanced anatomic and sometimes hemodynamic understanding and also improves procedural planning and allows interventional simulation. Also, it is helpful in communication with patients and trainees. These key advantages have led to its broad use in the field of cardiology ranging from congenital to vascular and valvular disease, particularly in structural heart interventions, where many emerging technologies are being developed and tested. This review summarizes the process of 3-dimensional printing and the workflow from imaging acquisition to model generation and discusses the cardiac applications of 3-dimensional printing focusing on its use in percutaneous structural interventions, where procedural planning now commonly relies on 3-dimensional printed models.

Background: The emerging Three-dimensional (3D) modelling improves intraoperative visualization, management, and analysis of available imaging data, the 3D form of available image, provides the surgeon with a better comprehension of the geometry, size, and exact relationship between target and normal tissue. The role of 3D modelling in orthopedic pelvic and hip surgical planning is brought to focus.Methods: The Medline database was searched using the keywords 3D printing, three dimensional printing, 3 dimensional printing and the results were screened for pelvis and hip surgery related full text articles. The duplicates and non-related articles were removed.Results: The articles were used to build a review with focus on Acetabulum, Pelvis, Hip and sacrum. We found that the role of 3D printing is non-negligible. The advances made with the help of 3D printing are wonderful and promising. The use of 3D saw its application in many fields. But the orthopedic surgery to our observance has benefitted the most till now.Conclusions: With the advances in the technology it is needed to make the 3D modelling easier, quicker, accurate, cost effective and reliable to help implement its deeper use in orthopedics. The authors believe that the 3D printing is an enormous help for the orthopedic surgeons which will only lead to positive outcomes.

Abstract Background: Three-dimensional printing is increasingly utilised for congenital heart defect procedural planning. CT or MR datasets are typically used for printing, but similar datasets can be obtained from three-dimensional rotational angiography. We sought to assess the feasibility and accuracy of printing three-dimensional models of CHD from rotational angiography datasets. Methods: Retrospective review of CHD catheterisations using rotational angiography was performed, and patient and procedural details were collected. Imaging data from rotational angiography were segmented, cleaned, and printed with polylactic acid on a Dremel® 3D Idea Builder (Dremel, Mount Prospect, IL, USA). Printing time and materials’ costs were captured. CT scans of printed models were compared objectively to the original virtual models. Two independent, non-interventional paediatric cardiologists provided subjective ratings of the quality and accuracy of the printed models. Results: Rotational angiography data from 15 catheterisations on vascular structures were printed. Median print time was 3.83 hours, and material costs were $2.84. The CT scans of the printed models highly matched with the original digital models (root mean square for Hausdorff distance 0.013 ± 0.003 mesh units). Independent reviewers correctly described 80 and 87% of the models (p = 0.334) and reported high quality and accuracy (5 versus 5, p = NS; κ = 0.615). Conclusion: Imaging data from rotational angiography can be converted into accurate three-dimensional-printed models of CHD. The cost of printing the models was negligible, but the print time was prohibitive for real-time use. As the speed of three-dimensional printing technology increases, novel future applications may allow for printing patient-specific devices based on rotational angiography datasets.

Background and Aims: Additive manufacturing or three-dimensional printing is a novel production methodology for producing patient-specific models, medical aids, tools, and implants. However, the clinical impact of this technology is unknown. In this study, we sought to characterize the clinical adoption of medical additive manufacturing in Finland in 2016–2017. We focused on non-dental usage at university hospitals. Materials and Methods: A questionnaire containing five questions was sent by email to all operative, radiologic, and oncologic departments of all university hospitals in Finland. Respondents who reported extensive use of medical additive manufacturing were contacted with additional, personalized questions. Results: Of the 115 questionnaires sent, 58 received answers. Of the responders, 41% identified as non-users, including all general/gastrointestinal (GI) and vascular surgeons, urologists, and gynecologists; 23% identified as experimenters or previous users; and 36% identified as heavy users. Usage was concentrated around the head area by various specialties (neurosurgical, craniomaxillofacial, ear, nose and throat diseases (ENT), plastic surgery). Applications included repair of cranial vault defects and malformations, surgical oncology, trauma, and cleft palate reconstruction. Some routine usage was also reported in orthopedics. In addition to these patient-specific uses, we identified several off-the-shelf medical components that were produced by additive manufacturing, while some important patient-specific components were produced by traditional methodologies such as milling. Conclusion: During 2016–2017, medical additive manufacturing in Finland was routinely used at university hospitals for several applications in the head area. Outside of this area, usage was much less common. Future research should include all patient-specific products created by a computer-aided design/manufacture workflow from imaging data, instead of concentrating on the production methodology.

Abstract The purpose of this study was to develop and demonstrate a novel imaging platform that post-processes volumetric imaging data (e.g. Computed Tomography (CT) or Magnetic Resonance angiography) to provide holographic visualization for pre-procedural treatment planning of a morphologically complex brain aneurysm. Digital CT images were segmented, using the Materialise Mimics software, into three-dimensional digital models that were imported into a prototype application for the Microsoft HoloLens. Feedback from testing the prototype indicated potential for augmented reality to assist an interventionalist in spatial understanding and depth perception of spatially complex anatomy and could increase confidence in pre-procedural planning. Future studies will be conducted with additional cases to further validate the utility of the platform in surgical planning decisions and to expand the platform for patient/resident education, telemedicine, and intra-operative use.

BackgroundThere is a significant learning curve when teaching ultrasonography to medical trainees; task trainers can help learners to bridge this gap and develop their skills. Three-dimensional printing technology has the potential to be a great tool in the development of such simulators. ObjectiveThis scoping review aimed to identify what 3D-printed models have been used in ultrasound education to date, how they were created and the pros and limitations involved.DesignResearchers searched three online databases to identify 3D-printed ultrasound models used in medical education.ResultsTwelve suitable publications were identified for inclusion in this review. The models from included articles simulated largely low frequency and/or high stakes events, with many models simulating needle guidance procedures. Most models were created by using patient imaging data and a computer-aided design software to print structures directly or print casting molds. The benefits of 3D-printed educational trainers are their low cost, reproducibility, patient specificity and accuracy. The current limitations of this technology are upfront investments and a lack of optimisation of materials.ConclusionsThe use of 3D-printed ultrasound task trainers is in its infancy, and more research is needed to determine whether or not this technology will benefit medical learners in the future.
