abstract = {Background: This study reports the first known application of 3-dimensional (3D) printing of cardiac tumors to preoperatively plan debulking in infants. 3D-printed cardiac tumor models were used to identify the spacial relationship between the tumors and coronary arteries as well as understand the depth and infiltration of the tumors.
Methods: Physical 3D cardiac tumor models of two children were obtained using medical imaging, image 3D rendering and modeling, and 3D printing. The hearts were 3D-printed in an opaque material while the tumors were made transparent to allow optimal visualization of the cardiovascular anatomy within the tumor. The surgical team used these models to plan exposure of the tumor, as well as, the extent of debulking.
Results: Patient 1 had a cardiac tumor arising from the anterior surface of the right ventricle causing significant right ventricular outflow tract obstruction and involving the right and left coronary artery courses. Patient 2 had a cardiac tumor arising from the left ventricle and extending beyond the left atrium compressing the airway preventing extubation, and surrounding the left coronary artery system. In both patients, 3D-printed models were used to maximize debulking and avoid injury to the coronaries.
Conclusions: 3D-printed cardiac tumor and anatomic models were effectively used to preoperatively plan two pediatric tumor debulkings. Both patients had tumors that were integrally involved with the coronary arteries. The 3D models helped devise a safe surgical strategy for maximal tumor debulking while protecting the coronary circulation.},
