Three-Dimensional Printed Cardiac Models for Focused Cardiac Ultrasound Instruction.

Utilizing 3D heart models in an FCU workshop format results in similar skill acquisition and knowledge retention as traditional didactics. The 3D heart models are relatively inexpensive, portable, and reusable, enabling learners to practice repeatedly and at flexible intervals. The reduction in ongoing expenses and the ability to teach large groups may decrease training costs as well as the need for local faculty expertise.
