Conflicts of Interest: The author has no conflicts of interest to declare. Although 3D-printed models did not add beneficial value for understanding simple CHD such as VSD, they significantly increased participants confidence and knowledge in complex CHD such as ToF. Furthermore, the 30-day readmission and 30-day mortality rates were lower with use of 3D-printed models when compared to the standard of care, although this did not reach statistical significance. In short, it's quick, affordable, and precise. This further confirms the advantages of 3D-printed physical models over traditional image visualizations for demonstrating complex cardiac lesions with a higher level of understanding.

Despite promising results available in the literature, traditional two-dimensional (2D) and three-dimensional (3D) visualization tools are still limited to a 2D screen, which affect realistic visualization of anatomical structures and pathologies of 3D datasets, and this is particularly apparent when dealing with complex pathologies. An emerging research direction in using 3D-printed models is to develop optimal scanning protocols with low radiation dose and acceptable image quality (46). Seventy-nine 3D models were specially used in the surgical planning of CHD cases. 3D-printed models have been further confirmed to be an effective tool in surgical planning of complex CHD patients, although prospective multicenter trials are needed to validate these findings.

Patient-specific coronary artery models were printed using soft and elastic TangoPlus material, while calcified plaques were printed with rigid VeroWhite material to represent calcification. Up until a couple of years ago, there were only a few hospitals doing 3D printing directly in the hospital.. Hopefully, it reduces morbidity and mortality, he said. 7 3D printing could also one day be used to make personalized treatments that combine multiple drugs into one pill, or a "polypill." 8 Additionally, researchers are using bioprin. Researchers have used 3D printers to create a knee meniscus, heart valve, spinal disk, other types of cartilage and bone, and an artificial ear.4,6,7 Cui and colleagues applied inkjet 3D printing technology to repair human articular cartilage.13 Wang et al used 3D bioprinting technology to deposit different cells within various biocompatible hydrogels to produce an artificial liver.13 Doctors at the University of Michigan published a case study in the New England Journal of Medicine reporting that use of a 3D printer and CT images of a patients airway enabled them to fabricate a precisely modeled, bioresorbable tracheal splint that was surgically implanted in a baby with tracheobronchomalacia.7 The baby recovered, and full resorption of the splint is expected to occur within three years.7, A number of biotech companies have focused on creating tissues and organs for medical research.7 It may be possible to rapidly screen new potential therapeutic drugs on patient tissue, greatly cutting research costs and time.1 Scientists at Organovo are developing strips of printed liver tissue for this purpose; soon, they expect the material will be advanced enough to use in screening new drug treatments.7 Other researchers are working on techniques to grow complete human organs that can be used for screening purposes during drug discovery.6 An organ created from a patients own stem cells could also be used to screen treatments to determine if a drug will be effective for that individual.3, Proof-of-concept studies regarding bioprinting have been performed successfully, but the organs that have been produced are miniature and relatively simple.1,9,10 They are also often avascular, aneural, alymphatic, thin, or hollow, and are nourished by the diffusion from host vasculature.1,6,9,10 However, when the thickness of the engineered tissue exceeds 150200 micro meters, it surpasses the limitation for oxygen diffusion between host and transplanted tissue.10 As a result, bioprinting complex 3D organs will require building precise multicellular structures with vascular network integration, which has not yet been done.6, Most organs needed for transplantation are thick and complex, such as the kidney, liver, and heart.11 Cells in these large organ structures cannot maintain their metabolic functions without vascularization, which is normally provided by blood vessels.13 Therefore, functional vasculature must be bioprinted into fabricated organs to supply the cells with oxygen/gas exchange, nutrients, growth factors, and waste-product removalall of which are needed for maturation during perfusion.10,13 Although the conventional tissue engineering approach is not now capable of creating complex vascularized organs, bioprinting shows promise in resolving this critical limitation.10 The precise placement of multiple cell types is required to fabricate thick and complex organs, and for the simultaneous construction of the integrated vascular or microvascular system that is critical for these organs to function.10, TIJ printers are considered to be the most promising for this use. The global rise of 3D printing during the COVID-19 pandemic Researchers make regenerative medicine - 3D Printing Industry The current COVID-19 crisis underscored the value of 3D-printing technology in addressing critical shortages in the medical product supply chain. One of the more immediate emerging trends is the use of 3D printing directly in hospitals, said Dr. Justin Ryan, a biomedical engineer and research scientist at Phoenix Childrens Hospitals Cardiac 3D Print Lab.
