Building a 3D Heart Library

Building a 3D Heart Library

Creating a Process

Through my interest in congenital cardiac MRI, I have been able to team up with Jump to start working on creating exact replica models of children’s hearts. We’ve been on this journey where we are creating processes that have never existed before, and the innovative part of the Jump lab is this mindset that if it doesn’t exist, we will create it.

It’s been very fun to be a part of this project in which we produce a 3D heart from 2D images. Over the past year we’ve been refining our process. We’ve had challenges, but also successes. We’ve now refined it down to where we can fairly quickly take a heart out of an MRI and put it into our hands.

For example, last week I had two requests for patients that already had MRIs for their actual heart models, and by the end of the week we had the models printed. It’s been a tool that our surgeons are coming to rely on. Even just this morning I was down in the OR taking a model model to the surgeon because he had a question prior to surgery.

The beauty of the whole project is that children with complex heart disease may have only of half of a heart to work with, so when you’re trying to figure out the optimal operation there’s no better way to do so than to actually see the heart and hold it in your hand before attempting the surgery.

Partnering with the NIH 3D Print Exchange

NIH 3D Print Exchange LogoWhile we are using these models for actual surgical planning – which I think is just a tremendous, incredible use for our patients – there’s also a lot of opportunities for sharing this information with the world in a type of library format. An issue that we’ve identified is that there aren’t anatomic models that describe congenital heart disease, or all the variations of tetralogy of fallot, truncus arteriosus, or total anomalous venous return as examples. It’s all been in pictures and textbooks. To be able to actually hold that model in your hand is a new kind of library – that is what we’re striving to achieve.

The logistics of how to create the architecture and be able to support having the library online was going to be a big hurdle. Luckily, the NIH 3D Print Exchange happened to come to life at the exact right time. We have been very impressed with their infrastructure, but more importantly their mindset. Speaking with Dr. Hurt at the NIH, it’s clear he understands the significance of taking something you’ve understood for years, printing it out, and holding it in your hands. This method can provide a whole new level of understanding. That’s exactly how we feel about these hearts.

For example, take something as simple as an Atrial Septal Defect (ASD) – something I’ve read about in textbook after textbook and have seen in thousands of echoes. When we printed out an ASD, and I was able to hold it in my hand, I learned something new. We’ve begun the process of taking these perfect examples of pathology, where we have great images, and creating 3D models that we’re now able to put on the NIH 3D Print Exchange that will allow anybody to go online, download the file, and print it out.

Establishing a Collaborative Effort

We hold ourselves to a very high QA standard, because we want people to learn and to use these models as training tools. Our next step is to elevate the project by working with a collaborative group of people and creating a peer review system that provides very accurate anatomic examples of congenital heart disease. We hope to take the benefit of the 3D modeling resources that we have available here at Jump and to make it available to anybody that’s willing to learn through the work the NIH is doing with the 3D Print Exchange.

Right now we have several hearts up on the website – two pathologic specimens that were designed for the library. Those were from patients with ideal images that demonstrated the specific anatomic detail. We have also included a brief description file on the website. Also on the Print Exchange are some of our research hearts. These hearts were designed to show certain elements that are useful in surgeries, but are not fully detailed. By having these hearts on the 3D Print exchange as we move forward, we will be able to reference them when we present at scientific meetings. They also provide a reference point if we decide to conduct research with those specific hearts. I think the work that the Print Exchange is doing is going to explode overnight at some point. There’s a lot of potential there, and while the project is still in its infancy, it contains tremendous molecular biology (more than what I care to know). We really see a lot of potential for the future of the NIH 3D Print Exchange and medical or anatomic libraries.

Now that we’ve opened this Pandora’s box we’re not getting out of it.

3D printing has certainly given an extra edge to medicine field. researchers, physicians and surgeons have added 3D printing service to create prosthetics, medicines, replicas of vital organs for practice surgeries and much more.  Even after so many innovations more research is taking place to create real vital organs through 3D printing that can be transplanted in the patients who need it. This will be a big thing and many lives can be saved in the future and especially those who die of not getting the organs on the right time.

Right now,  there are a handful of pathologic libraries. These libraries have developed over the years, but the majority of these hearts were from autopsies back 50 years ago and they’ve been handled and used over the years and they’re starting to fall apart.   armor games

I am trusting the same best exertion from you later on too. Actually your exploratory writing abilities has roused me. Burgess

Sarkari result is what most of the Indian students are finding these days for. sarkari result exams helps in giving all the sarkari jobs, sarkari exams and result information to aspiring students.
Students prefer giving govt exams for govt jobs rather than going for private jobs because the pay scale in govt jobs is good and also the it secures the life of a person because govt job assures job security.
So if you are thinking that due to busy schedule you might miss an important govt job notification then don't worry as we are here to help you out with that.

<p>The first section of the paper addresses settings and techniques, including the basic sequences used in paediatric CMR, safety, and sedation. In the second section, the indication, application, and clinical relevance of CMR in the most frequent CHD are discussed in detail. In the current era of data driven multimodality imaging, the strengths of CMR are compared with other imaging modalities. At the end of each chapter, a brief summary with expert consensus key points is provided. The recommendations provided are strongly clinically oriented. The paper addresses not only imagers performing CMR, but also clinical cardiologists who want to know which information can be obtained by CMR and how to integrate it in data-driven decision-making.

Nice. First thing im printing when i get the creality 3. Best Tree Care Service

As a science student, I've been very fascinated with such leaps in technologies that eventually go and help thousands of people and make their lives better. Just recently, a friend of mine from Australia mentioned how his colleague knows someone who got fitted with a prosthetic limb that completely changed his life for good. It is amazing how medicine and technology can go together so well and we're looking at such a hopeful future. Since I run a web design company in Mumbai, I'd love to build a website for a charitable cause completely for free (if someone wants it). After all, giving back to the society is very rewarding in itself.

This is very cool! :) 

Thanks for a great and intressting post. I read your website as often as possible, very impressed. Matkassar

A 3D heart, especially one that has actual medical use, is a great way to prove that 3D printing is a valuable technology, and not exclusive to hobbyists with too much spare time and money.

I like the information you shared.

Very unique and awesome lines.

The construction of 3D hearts seemed like the stuff of sci-fi only a decade ago. Now it's reality. Next stop should be mass market accessibility.

Creating a 3D Model of the heart is a great idea specially for doctors explaining the current heart situation of their patients.  With Outbound Lighting, the model will surely to very good.

Thanks for sharing I m wondering if anyone ever read about blue dragon river

I found skeet shooting – on StumbleUpon today and thought I’d check it out. I bookmarked it and will be back to check it out some more later.

Definitely imagine that that you said. Your favourite reason appeared to be on the web the easiest thing to be mindful of. I also want to share that you can now play Subway Surfers online game on your PC!

Technology is the answer and hope for future generations, love your idea of creating a library and also love your interest in helping children with heart conditions, here in Miami, FL our company concrete Miami is part of few events helping the community especially kids.

Great job!
