3D printing techniques improve surgical outcomes for cardiac tumors in patients with IgG4-RD

Three-dimensional (3D) reconstruction and printing significantly improve the surgical planning and treatment of complex cardiac tumors, including those associated with IgG4-related disease (IgG4-RD), according to a study.

A report involving a patient with IgG4-RD affecting the heart showcases the utility of 3D printing in managing rare cardiac masses. The patient underwent ECG-gated cardiac computed tomography angiography (CCTA), which revealed the complexity and large size of their mass and their proximity to vital cardiac structures.

To facilitate optimal surgical planning, a 3D model was created. Total surgical resection was performed without complications, and no signs of recurrence were observed at the 12-month follow-up.
