Stent-assisted coil embolization (SACE) is widely accepted for the endovascular treatment of wide-neck or complex cerebral aneurysms. Dr. Kenichi Kono and his team at the Showa University Fujigaoka Hospital of Kanagawa in Japan have assessed and compared the hemodynamic effect of stent struts and straightening of vessels. They tested out the effects of stent placement on reducing flow velocity in sidewall cerebral aneurysms with the goal of reducing recanalization rates. Thanks to this groundbreaking study, Dr. Kono was the Global Mimics Innovation Award winner in 2015.
Despite careful planning, the complex dimensions of the left atrial appendage (LAA) and its variable morphology can result in procedural failure. To make their pre-operative planning even more thorough, a team of Australian physicians from the Victor Chang Cardiac Research Institute in Sydney turned to medical 3D Printing. The team created an exact replica of a patient's heart while planning a LAA closure procedure with a Boston Scientific Watchman™ device.
What do donor hearts and 3D Printing have in common? The answer to this is the University of Minnesota’s Visible Heart® Lab. Not content with simply teaching their students with 2D images, the team at the lab has moved their academic approach to a whole new level: 3D models of real human hearts. Imagine being able to train as a surgeon with a complete, tangible heart model, as opposed to learning off paper! And imagine acquiring the skills to make 3D models for any operation you might perform throughout your career? Here’s how Materialise enables the Visible Heart Lab’s unique approach to teaching, education and research.
Interview with Werner Budts, MD, PhD - Cardiologist at University Hospitals Leuven, Belgium Prof. Werner Budts can be considered one of the primary advocates on the implementation of 3D Printing in cardiology. For quite some time, he has been turning his digital image data into printable 3D models, using his own desktop 3D printer. The Materialise team visited him to discuss his vision about Medical 3D Printing in hospitals.
37-year-old Sneha Cipriano discovered she had a large renal artery aneurysm located near the back of her right kidney. This type of aneurysm is extremely rare and is usually found in young women who have had multiple pregnancies. As large aneurysms are more in danger of rupturing, and as a ruptured aneurysm can be life-threatening, it was important to repair it with a surgical graft as soon as possible. However, the position of the aneurysm on the split of the renal artery meant that operating on it with minimal risk would be quite difficult.
At the Hospital for Sick Children in Toronto, Canada, the cardiovascular surgery division led by Dr. Glen Van Arsdell is using 3D-printed models to train new surgeons before they perform complex pediatric surgery. This solution resolves a dire need for proper training and practice, which is often limited to practicing on organ donations or animals.
Fuwai Hospital in Beijing is China’s largest hospital devoted exclusively to the diagnosis and treatment of cardiovascular diseases. Amongst other facilities, the hospital houses 962 beds, 19 OR’s, 11 cath labs and 2 hybrid-operation rooms. Besides, the institution is becoming the top 3D Printing center nationwide for complex cardiovascular applications. This year, Fuwai hospital will perform live cases for PICS-CSI Asia, the leading conference about congenital, structural and valvar interventions. In order to prepare for a complex Transcatheter Aortic Valve Implantation (TAVI) case, Dr. Yongjian Wu, Interventional Cardiologist and Head of Cardiology at Fuwai, relied on the expertise of Materialise and validated process.
An interesting application of 3D Printing & visualization software is disease modeling. For example, the development of aortic aneurysms, life-threatening dilations of the aorta, is affected by a wide range of environmental and genetic factors. Therefore, aortic aneurysms are difficult to study clinically and experimentally. A team of researchers at the University of Rochester, New York, including Dr. Ankur Chandra, Associate Professor of surgery and biomedical engineering and a practicing vascular surgeon himself, took the challenge.
