3D Printing of Cardiac Tumors

Cardiac tumors, which are rare cardiac diseases, can be classified into primary cardiac tumors and secondary cardiac tumors. In 2004, the WHO classified cardiac tumors into benign tumors, tumor-like lesions, and malignant tumors [1]. 75% of primary cardiac tumors are benign, and the other 25% are malignant tumors. According to previous reports, three-fourths of all cardiac tumors are benign tumors, nearly half of which are myxomas, with the other half being lipomas, papillary fibroelastoma, and rhabdomyomas; most malignant tumors were undifferentiated sarcomas, followed by angiosarcoma, rhabdomyosarcoma, lymphoma, and so on [2].
