The Zygote Solid 3D Heart Model is the most comprehensive and medically accurate 3D CAD model of the human heart. It is a highly accurate model created for use within all major engineering applications for finite element analysis, product design, and visualization. This carefully crafted model is based on human CT and MRI scans, and accurately defines key anatomical features including heart-chamber volumes and wall thickness with clean and efficient geometry.Solid Heart Model Anatomical Details Include:

"Here at Zoic the Zygote models have been an incredible and powerful asset for production. Specifically on "CSI" it has allowed for a nearly complete transition away from traditional prop building for all of our human anatomy shots. We use Zygote to digitally create the intricate and mysterious worlds of the human body. This results in allowing us and the writers to explore almost any area of the human body one can imagine."

Engineered heart tissues (EHTs) that are fabricated using human induced pluripotent stem cells (hiPSCs) have been considered as potential cardiac tissue substitutes in case of heart failure. In the present study, we have created hiPSC-derived cardiac organoids (hiPSC-COs) comprised of hiPSC-derived cardiomyocytes, human umbilical vein endothelial cells, and human fibroblasts. To produce a beating conduit for patients suffering from congenital heart diseases, we constructed scaffold-free tubular EHTs (T-EHTs) using hiPSC-COs and bio-3D printing with needle arrays. The bio-3D printed T-EHTs were cut open and transplanted around the abdominal aorta as well as the inferior vena cava (IVC) of NOG mice. The transplanted T-EHTs were covered with the omentum, and the abdomen was closed after completion of the procedure. Additionally, to compare the functionality of hiPSC-COs with that of T-EHTs, we transplanted the former around the aorta and IVC as well as injecting them into the subcutaneous tissue on the back of the mice. After 1 m of the transplantation procedures, we observed the beating of the T-EHTs in the mice. In histological analysis, the T-EHTs showed clear striation of the myocardium and vascularization compared to hiPSC-COs transplanted around the aorta or in subcutaneous tissue. Based on these results, bio-3D-printed T-EHTs exhibited a better maturation in vivo as compared to the hiPSC-COs. Therefore, these beating T-EHTs may form conduits for congenital heart disease patients, and T-EHT transplantation can form a treatment option in such cases.

I researched tutorials for how to print a 3D heart model from a CT or MRI scan. There are currently no tutorials for printing 3D hearts that takes you all the way from the DICOM files to the printer. This was quite a challenge and I still have a lot more work to do. This tutorial is only for an external 3D model of the heart. I have not found an easy way to create an accurate 3D model of the internal chambers/structures of the heart. I will continue to research this throughout the semester and repost when I discover a succinct way to accomplish this (any advice is greatly appreciated).

I delved into three different techniques which each utilized a different software. First, I investigated 3D slicer, which is an open sourced NIH sponsored 3D imaging software. Slicer is the equivalent of R in the statistics world, which means there is infinite potential, but it is also not very user friendly. Slicer has plugins that you can download which sound like they outline and make automatic traces of certain body parts. This would be the perfect platform for what I would like to accomplish. Osirix also has plugins you can download, but development would be much slower since it is not open source. Osirix is also only for Mac, this is a huge limitation of the tutorial. I will eventually discover a nice way to create a model with a PC as well.

The second way in which I know people are creating 3D models of the heart is by using Mimics, which is a privately owned software by Materialise ($$$). In this software, you make things similar to the ROIs that we will make in Osirix called masks. I do not have access to this software so I was not able to play around with it.

The most widely used software and arguably the most well known to practicing Radiologists is OsiriX. OsiriX has a free version available to the public which you can download here: -viewer.com/Downloads.html This is the software we will use for my tutorial, again Macs only.

3D printed heart models showing normal anatomy and pathology. (a) Normal heart model created from cardiac CT and is partitioned into three pieces allowing visualization of interventricular septum. (b) Repaired tetralogy of Fallot (ToF) from an adult patient. The model was created from cardiac magnetic resonance imaging (MRI) and separated into two pieces allowing for clear visualization of overriding aorta and pulmonary infundibular stenosis. (c) Unrepaired ToF heart model from an infant. The model was created from 3D echocardiographic images and partitioned into two pieces showing the ventricular septal defect (VSD). (d) Unrepaired ToF heart model from an infant with superior and inferior portions showing VSD and the aortic overriding in relation to the VSD.

Fluoroscopic documentation of balloon dilatation of valvular stenosis with the 3D printed heart model. (A): Balloon dilatation of a valvular aortic stenosis. The inflated balloon is positioned at the level of the aortic valve. The long guidewire is inserted via the descending aorta with its tip lying in the LV. (B): Balloon dilatation of a valvular pulmonary stenosis. The inflated balloon is positioned at the level of the pulmonary valve. The long guide wire is inserted via the inferior vena cava through the RA into the RV, with its tip lying in the right pulmonary artery.

Several studies have explored the feasibility of developing 3D printed heart and vascular models for CT dose optimization [81,82,83,84,85,86,87,88,89,90]. Abdullah et al. developed an organ-specific cardiac insert phantom for the investigation of cardiac CT scanning protocols. Although it does represent the novelty of the study design with the simulation of surrounding cardiac structures as well as contrast medium during cardiac CT scan (Figure 10), the study lacks personalized 3D printed anatomical structures [81]. Morup et al. tested four different materials (gelatin mixtures, pig hearts and EcoflexTM silicone) with the aim of determining the appropriate one to simulate human heart and vascular tissue properties. Their results showed that the contrast-filled Ecoflex TM silicone had a mean CT attenuation of 318 Hounsfield Units (HUs) which is close to the contrast enhancement CT attenuation in real patients (Figure 11), serving as a cost-effective model for CT protocol optimization [82]. 2ff7e9595c
