Congenital heart diseases causing significant hemodynamic and functional consequences require surgical repair. Understanding of the precise surgical anatomy is often challenging and can be inadequate or wrong. Modern high resolution imaging techniques and 3D printing technology allow 3D printing of the replicas of the patient's heart for precise understanding of the complex anatomy, hands-on simulation of surgical and interventional procedures, and morphology teaching of the medical professionals and patients.

Objective: Although simulation-based education is now commonly utilized in medicine, its use in the instruction of congenital heart disease remains limited. The objective of this study is to evaluate whether heart models created with three-dimensional printing technology can be effectively incorporated into a simulation-based congenital heart disease and critical care training curriculum for pediatric resident physicians.

Design: Utilizing heart models created with a three-dimensional printer, pediatric residents participated in a 60-minute simulation seminar with three consecutive components: (1) didactic instruction on ventricular septal defect anatomy; (2) didactic/simulation-based instruction on echocardiographic imaging of ventricular septal defects and anatomical teaching/operative simulation of ventricular septal defect repair; (3) simulation-based instruction on postoperative critical care management of ventricular septal defects.

Background: The current educational approach for teaching congenital heart disease (CHD) anatomy to students involves instructional tools and techniques that have significant limitations. This study sought to assess the feasibility of utilizing present-day three-dimensional (3D) printing technology to create high-fidelity synthetic heart models with ventricular septal defect (VSD) lesions and applying these models to a novel, simulation-based educational curriculum for premedical and medical students.

Methods: Archived, de-identified magnetic resonance images of five common VSD subtypes were obtained.

Transcatheter creation and enlargement of interatrial defects (IAD) may improve hemodynamics; however, procedural outcomes have not been well defined. Hospital records were reviewed for children who underwent percutaneous procedures to create and enlarge an IAD and were grouped as follows: (1) right and (2) left heart obstructive lesions, (3) left atrial (LA) decompression during left heart assist, (4) failing Fontan circulation, and (5) miscellaneous. Forty-five children (mean age, 3.
