Velocity Contours in Iso-Surfaces for The Re-Stenosed Pulmonary Artery

The entrance lenght parts of the inlet and outlet sections are only used for calculation process.

Wall Shear Stress

Pediatric re-stenosed pulmonary artery model is depicted with marked points of unstable wall shear stress (WSS) which brings about the thinner layers by platelets. This means the loss of smooth muscle cells and remodeling risk. Sudden bends and tapering in the geometry induces high velocity gradients and high wall shear stress.

Carol Malnati

“- I wanted to be someone that encouraged young women to get involved in math, science, and engineering.”

Today, she’s doing just that.

As a product development engineer in the Medtronic cardiovascular division, Carol has been doing what she loves for more than 25 years. She provided critical technical expertise for the company’s first implantable cardioverter defibrillator and continues to collaborate with engineering teams and physicians to find new ways of doing things.

But on top of her day job, she has taken on another commitment – overseeing the Women in Science and Engineering (WISE) Initiative at the company.

Beginning in the spring of 2017, Medtronic introduced another opportunity that taps into an often overlooked talent pool.  Careers 2.0 is a “returnship” program designed to provide paid internships for female engineers looking to get back into STEM-related careers. Research suggests close to 25 percent of women in engineering careers leave the industry by age 30, citing work culture or family commitments.

“This is a way to bring these talented women back into our technical and managerial ranks,” says Carol. “We are very excited about providing this amazing pool of talent an opportunity at Medtronic.”

“Overall, I want to inspire women,” says Carol. “Whatever your passion is; clean air, fighting hunger, or improving healthcare. Behind the biggest challenges of humanity, there’s an engineer working to find a solution.”

Surgical Planning and 3D Printed Hearts

Alistair Phillips, MD, who is the Co-Chair for the American College of Cardiology, Surgeons Section tells about some of the impacts he has personally experienced using 3D printing in surgical settings as his participation in the 3DHEART program:

“The clinical trial is particularly exciting as it targets specific cases in which understanding of the anatomy will greatly enhance the surgical approach. A 3D printed replica of a patient’s heart will be created as part of the inclusion criteria to be in the study.Using 3D printing gave a better understanding of the Hybrid procedure, and allowed us to perform pulmonary valve replacement with a minimally invasive approach avoiding conventional method that required open-heart surgery. After coming to Cedars-Sinai we refined the pre-ventricular approach by utilizing a 3D printed models of patients’ hearts. We were able to simulate the implant into the right ventricular outflow tract.

Every surgeon is different. The education, experience, aptitudes, and attitude we bring to each equally nuanced and varied patient span an almost limitless spectrum and inform how we may utilize 3D printing for the benefit of our patients. The elegance of 3D printing is that it can create the individualized tools spanning this spectrum.

That said, however, what is not negotiable is the veracity of the models that we are receiving. Various materials and their corresponding colouring or rigidity may serve different functions in the hands of different surgeons, but ultimately we must have the utmost confidence in the fidelity of the models we are utilizing for pre-surgical planning. The more realistic the model is both in anatomical and textural preciousness will greatly enhance the application.

In all honesty, I would advise each hospital to start by really understanding the value proposition 3D printing offers across all specialities and, the culture of their institution. The best way to get answers to these very nebulous, complicated, nuanced directives is by retaining an outside vendor to provide as much of the services as possible, from the proverbial soup to nuts.

The excitement around the 3DHEART clinical trial is so great because it is the first organized, large-scale attempt to collect evidence of the efficacies of 3D printing in the practice of medicine and delivery of healthcare, not only in terms of optimized patient outcomes but also with respect to lower costs. If we can get reimbursement for 3D models, it is without a doubt a game-changer in terms of the practice of medicine, and a life-changer for many of our patients.”
