VR and 3D Printing for Preop Planning of Left Ventricular Myxoma in a Child.

We report a highly rare case of a large left ventricular myxoma with left ventricular outflow tract obstruction in a previously healthy, asymptomatic 7-year-old male patient. For preoperative planning, we used end-diastolic computed tomography data to model the patient's cardiovascular structures and then generated a virtual reality model and a 3-dimensional-printed model. They helped the surgeon completely manage the details of the surgery. The mass was completely resected in one piece uneventfully. Histopathologic examination confirmed the diagnosis of myxoma. We believe that 3-dimensional technologies may be effective if the traditional modalities were insufficient in those rare, complex, and heterogeneous cases.
