Three-Dimensional Printing for Planning of Structural Heart Interventions

: Three-dimensional (3D) printing is a process leading to the creation of a physical 3D model used for teaching, patient education, device evaluation, and procedural planning. 3D printed models of patient-specific anatomy can be generated from 3D transesophageal, cardiac MRI, or cardiac computed tomographic datasets. This article discusses the potential advantages of 3D printing, reviews the different modalities to acquire a 3D dataset, and highlights the application of 3D printing to enhance patient screening and procedural planning in structural heart intervention.
