Three-dimensional (3-D) printed anatomic models created from a patient’s computed tomography (CT), magnetic resonance imaging (MRI) or 3-D ultrasound imaging datasets are seeing increasing use for procedural planning and hands-on clinical education. Some cardiovascular centers have created their own 3-D printing labs to enable on-demand printing of complex anatomy not only for planning and device sizing, but also to practice dry runs and aid procedural navigation. An emerging trend is the use of new 3-D computer modeling software to enable virtual device implantations for improved patient selection, to reduce complications, and enable faster development of novel transcatheter devices and procedural techniques.Â
