3D printing technology more and more applications in the field of cardiology. Following last year several top three hospitals in Shanghai to apply it to the left atrial appendage occlusion, Beijing Fu Wai Hospital successfully apply it to other areas of treatment of congenital heart disease.

Recently, Fu Wai Hospital, led by Professor Zheng Hong Interventional Radiology, interventional surgical team to one of its "inferior vena atrial septal defect" in patients with occlusion success, breaking the lower chamber atrial septal defects can not do interventional therapy taboo, many congenital heart disease patients from the pain of thoracotomy surgery. Professor Zheng Hong's secret weapon is the 3D printing technology.

3D printing technology a few years ago has been applied in the field of medical devices, it can generate direct organ structure, print out the three-dimensional model, doctors judge, implement complex surgery. Patient's heart surgery is very complex, doctors need to be selected for models of medical devices. Before surgery, the patient's heart print model, doctors can have patients on cardiac structure in a more accurate determination, research, choosing to be placed PDA occluder, coupled with technical skill can greatly enhance the success rate of treatment, so many of the original surgery impossible becomes possible. Currently, 3D printing technology is mainly used in cardiology, structural heart disease, especially for complex congenital heart disease diagnosis and treatment play an unexpected role in promoting, 3D printing technology makes many diseases (especially structural heart disease) entering personalized treatment that is "private custom" era.

According to the reporter, since 2009 Professor Zheng Hong began to focus on the development of 3D printing technology, since 2012, has been completed and particularity complex congenital heart disease, heart disease and other cardiovascular LAA model making 16 cases times, according to the digital images and 3D printing model design, apply for and obtain congenital heart disease and new LAA occluder, such as patents 3, respectively, in November 2013 and September 2014 to complete the country's first "3D Print Advisor dismount Rockwell Fallot surgery After aortic sinus aneurysm intervention therapy "and" 3DP technical guidance using PDA occluder ASD cases treatment of cavity success ", the latter through the Beijing Scientific and Technical Information of the new investigation demonstrate the world's first.

As China's "Thirteen Five national strategic research program focused on the task" -3D printing technology in mind one of the drafters Diseases application and strategic planning, Professor Zheng Hong believes, should reinforce the printing of the first and second levels of basic 3D, mind applications of 3D printing technology Diseases established cardiovascular disease, especially digital model library of structural heart disease, compensate for the lack of an autopsy source of defects, the establishment of the library to bring precision and the best for each patient's treatment programs, but also to become surgical and interventional physicians learn about a variety of subjects such as cardiovascular malformations provide real "entity specimen" and training tools. In addition, the complexity of the digital model of structural heart disease and Internet technology, it can make telemedicine technology to a higher level, so that diagnosis and treatment of cardiovascular disease has become more easy and convenient.

Zheng noted that the highest level of 3D printing technology is through the cells and tissues of human organs 3D printing to create alternatives, such as active and functional blood vessels, heart valves and other tissues and even organs. As cell and tissue third dimension of 3D printing, China should set up their own superiority team, and developed research progress in this area closely follow, through a variety of channels to obtain the latest technology to study, visit, exchange and cooperation, through the learning, improving and innovation to achieve more with less purpose
