3D printing technology-based diagnosis and therapeutic pattern in complex congenital heart disease: single center experience in 40 patients

Abstract

Objective To evaluate the value of three-dimensional(3D) printing technique in the diagnosis and treatment of complex congenital heart disease(CHD). Methods From March 2016 to February 2018, 40 patients with complex CHD underwent heart CT scanning. The CT images were imported to Standard Template Library(STL) files after 3D reconstruction and then exported for 3D printing. The 3D printed models were then used for decision making and navigation during surgery. Results Thirty patients were indicated for surgical operation. Three patients underwent single ventricular repair, and biventricular repair were operated on 27 patients. The 3D printed models were quite in accordance with the actual anatomical findings in all the patients. And all the procedures carried on were exactly same as planned based on 3D printed model. Conclusion The 3D printing may help improve the diagnosis and treatment level in complex CHD. Key words: 3D printing; Congenital heart disease
