Doctors with the Second Affiliated Hospital of Nanchang University in east China's Jiangxi Province have used 3D printing technology to assist a cardiovascular surgery. They have successfully performed a transcatheter aortic valve replacement (TAVR) surgery on a 73-year-old male patient with the help of the technology. The doctors used 3D printing technology to simulate the surgery before making the final plan. The technology could also help doctors design more personalized treatment solutions.
