Cardiovascular diseases include all types of cerebrovascular diseases. It refers to the general term of hemorrhagic or ischemic diseases of heart, brain and whole body caused by hypertension, hyperlipidemia, atherosclerosis and other diseases, ranking first in the causes of death in the world. It is a serious threat to human health. Therefore, it is very important for the early detection and treatment of cardiovascular diseases. It is urgent to study new diagnosis and treatment methods. The emergence of 3D printing technology undoubtedly brings great convenience to clinical treatment.
3D printer is widely used in vascular surgery with its advantages of precision and convenience. In the process of printing 3D model, it generally includes three stages: model acquisition, 3D printing and post-processing. At present, the printing methods commonly used in the medical field, including
- direct 3D printing
- selective laser sintering (SLS)
- fused deposition modeling (FDM)
- stereo lithography
- biological printing
- inkjet printing
Application of 3D printing technology in cardiovascular disease
- High precision, accurate diagnosis
At present, the diagnosis and preoperative planning of cardiovascular diseases mainly rely on CTA, MRI and other imaging technologies. As we all know, the imageology results are often two-dimensional, which is not conducive to communication between doctors and patients. However, The 3D printing model based on image technology can make the examination more precise, and even show the anatomical structure and subtle lesions in the cardiovascular system, so that clinicians can observe the lesions from different perspectives, and diagnose them accurately.
- 3Dmodels, best operation strategy
3D printing model can also help clinicians to choose the best operation strategy and predict various possible problems during the operation. At the same time, 3D printing model can improve operation scheme, help to reduce radiation exposure, increase operation efficiency and ensure patient safety. Anwar (3D Printing is a Transformative Technology in Congenital Heart Disease[J]) pointed out that there are two main forms of 3D printing heart model: blood pool model and hollow heart model. The blood pool model refers to the display of the blood pool in the heart cavity and blood vessels by 3D printers. This model is usually used to contrast CT or MRI, and make clinicians. Hollow heart model refers to the display of heart muscle and blood vessel wall by the grid around the blood pool, which can display the intracardiac anatomy in detail.
3. Stimulation, planning, feasibility
At present, one of the latest technologies is to use 3D printers for preoperative planning. Before cardiovascular surgery, the model made by 3D printing technology can transform the imaging results into simulated real vascular, which is more conducive for doctors to make operation evaluations and plans. In 2018, Moore used 3D printing technology to establish a 3D model of blood vessels for 7-day-old newborns with interrupted aortic arch (IAA) and patent ductus arteriosus (PDA), which made it clear that the surgeons could anastomose the aorta with the space, successfully completed the operation and proved the feasibility of 3D printing preoperative planning.
Nowadays, 3D printing technology has been paid more and more attention inclinic because of its advantages of high precision, fast production speed and on-demand production. With the development of imaging technology and material science and technology, the accuracy and bionic degree of 3D printing of cardiovascular system will be improved continuously, which will provide strong support for the preparation of new bionic materials.
