In cases where surgical repair is insufficient to return the heart to normal function, a patient may proceed to advanced heart failure, and a heart transplant may be required. Unfortunately, a finite number of available donor hearts are available. A mechanical circulatory support (MCS) device can be used to bridge the time between heart failure and reception of a donor heart. These MCS devices are typically constructed for the adult population. Accordingly, the size associated to the device is a limiting factor for small adults or pediatric patients who often have smaller thoracic measurements. While current eligibility criteria are based on correlative measurements, the aforementioned 3D visualization capabilities can be leveraged to accomplish patient-specific fit analysis.
The main objectives of the work presented in this dissertation were 1) to develop and evaluate an optimized process for 3D printing cardiovascular anatomy for surgical planning and medical education and 2) to develop and evaluate computational tools to assess MCS device fit in specific patients. The evaluations for objectives 1 and 2 were completed with a collection of qualitative and quantitative validations. These validations include case studies to illustrate meaningful, qualitative results as well as quantitative results from surgical outcomes. The latter results present the first quantitative supporting evidence, beyond anecdotal case studies, regarding the efficacy of 3D printing for pre-procedural planning; this data is suitable as pilot data for clinical trials. The products of this work were used to plan 200 cardiovascular procedures (including 79 cardiothoracic surgeries at Phoenix Children's Hospital), via 3D printed heart models and assess MCS device fit in 29 patients across 6 countries.
Ctrl+P is an online store for 3D printed items, founded by four members with experience in computer-aided design (CAD) and financial management. They initially started with a broader scope but later focused on designing custom pool racks for the pool community. They conducted customer discovery with over 634 ASU students and landed an ongoing business deal with Mill’s Modern Social, a pool hall and bar in Tempe. The team has already made a profit and aims to be revenue-earning by the end of the project. The financial plan includes potential expenses for website development, printer filament, and 3D printers. Ctrl+P's brand mission is to print products desired by customers that consult Ctrl+P. The long-term goal of the team is to continue to gain customers and expand the business to a larger customer base.
This thesis paper outlines the Ctrl+P print store business, an honors thesis project conducted through the Founder’s Lab program at Arizona State University. The project is an online store for 3D printed items, operated by a team of four students with backgrounds in engineering and finance. Three team members have experience in computer-aided design (CAD) and can design products to print and sell, while the fourth member is responsible for the financial side of the business. The project began with a broader scope but later focused on the niche community of pool. In the spring semester, the team conducted customer discovery with over 600 ASU students; and in the fall semester, reached out to several pool halls to facilitate feedback on designs of custom pool racks. The team currently has a pending business deal with Mill’s Modern Social, a pool hall and bar in Tempe. The team's goal was to be revenue-earning by the end of the project, and they have already made a profit as a business.
Ctrl+P is a start-up business created through the founder's lab class at W.P. Carey. Our group created a 3D print shop that specializes in making products, such as customizable key chains and prominent landmarks, as well as custom 3D printed solutions for local businesses and companies.
