Advanced 3D Cardiac Anatomy Models

The University of Minnesota’s Visible Heart Lab has partnered with Stratasys Direct to help medical professionals create realistic, intricately detailed 3D cardiac anatomy models for education, surgical planning, and clinical communication. Combining advanced medical expertise with industry-leading 3D printing technology, this collaboration demonstrates how additive manufacturing is transforming patient-centric approaches to healthcare.

High-resolution 3D printed cardiac models provide surgeons, educators, and clinical teams with accurate physical representations that enhance procedural planning, medical training, and anatomical visualization. Unlike traditional imaging alone, these tangible models offer a hands-on understanding of cardiovascular anatomy that improves spatial awareness, collaboration, and confidence across both educational and clinical environments.

Medical schools, simulation labs, hospitals, and surgical teams increasingly rely on 3D anatomical models to support everything from classroom instruction to pre-operative preparation. In addition to improving training and planning, these models also strengthen communication between physicians and patients by turning complex anatomy into clear visual and tactile references that simplify treatment discussions and improve understanding of care strategies.

Whether used for consultation, education, or surgical preparation, custom 3D cardiac anatomy models provide a practical and impactful tool for modern healthcare environments.

ME 4CH VHL file image for 3d printing

ME 4CH

This view offers a favorable acoustic window for visualizing the left atrium (LA), right atrium (RA), left ventricle (LV), right ventricle (RV), tricuspid valve, and mitral valve (A3A2-P2P1). It is an extensive view that facilitates the assessment of anatomy and function. It is particularly useful for evaluating primum atrial septal defects (ASD), ventricular septal defects (VSD), and abnormalities such as Ebstein anomaly.

ME 2CH VHL file image for 3d printing

ME 2CH

The ME 2CH view is suitable for assessing regional left ventricular (LV) function, specifically the anterior and inferior walls, as well as the function of the mitral valve. It is one of the four recommended views for utilizing color Doppler across the mitral valve. The structures visible in this view include the left atrium (LA), left ventricle (LV), coronary sinus, mitral valve (P3-A3A2A1), and left atrial appendage.

ME LAX VHL file image for 3d printing

ME LAX

The ME LAX view allows visualization of the left atrium (LA), left ventricle (LV), left ventricular outflow tract (LVOT), right ventricular outflow tract (RVOT), aortic valve, mitral valve (P2-A2), and proximal ascending aorta. It is particularly useful for assessing regional left ventricular function in the inferolateral and anteroseptal walls, as well as the function of the mitral and aortic valves. Additionally, it provides appropriate visualization of membranous ventricular septal defects (VSD), and ascending aortopathy.

ME AV SAX VHL file image for 3d printing

ME AV SAX

The ME AV SAX view provides a tri-leaflet view of the aortic valve, with the left, noncoronary, and right cusps visible in the posterior, right, and anterior parts of the ultrasound screen, respectively. This view also includes the right atrium (RA), left atrium (LA), superior interatrial septum, right ventricular outflow tract (RVOT), and pulmonary valves. It allows imaging of patent foramen ovale (PFO), atrial septal defects (ASD), as well as assessment of aortic and pulmonary valve function.

ME Mitral Comm VHL file image for 3d printing

ME Mitral Comm.

The ME Mitral Comm. view enables focused analysis of the mitral valve structures, including P3-A3A2A1-P1, papillary muscles, and chordae tendineae. The left atrium (LA), left ventricle (LV), and coronary sinus are also visualized in this view. The diagnostic information obtained from this view includes assessment of mitral valve function and regional left ventricular function in the anterior/anterolateral and inferior/inferolateral walls.

TG Mid Papillary SAX View VHL file image for 3d printing

TG Mid Papillary SAX view

The TG Mid Papillary SAX view offers diagnostic information regarding global left ventricular (LV) function, LV size, and volume status. It allows simultaneous visualization of the segments supplied by the left anterior descending (LAD), circumflex, and right coronary arteries, making it suitable for intraoperative monitoring of cardiac function. The structures visible in this view include the papillary muscles, left ventricle, and right ventricle.r and right ventricle.

ME Bicaval View VHL file image for 3d printing

ME bicaval view

The ME Bicaval view provides visualization of the left atrium (LA), right atrium (RA), right atrial appendage, interatrial septum, superior vena cava (SVC), and inferior vena cava (IVC). It offers valuable diagnostic information for detecting interatrial shunts, atrial septal defects (ASD), and confirming the position of intra-atrial catheters.

Deep TG 5CH VHL file image for 3d printing

Deep TG 5CH view

The Deep TG 5CH view allows alignment of the Doppler beam with the aortic valve to observe transaortic flow and analyze peak velocities. It also permits interrogation of mitral valve function.
