Use of three-dimensional models to assist in the resection of malignant cardiac tumors

The application of three-dimensional (3D) printing enables the creation of material objects from digital images by depositing layers of plastic material into 3D structures and can be used for training, education, and surgical planning. We report two patients with large complex cardiac tumors where 3D technology was utilized to analyze the tumor size, location, and extension more precisely, allowing better preoperative planning and decision making.
