Silvia Schievano

Schievano was an undergraduate student in engineering at the Polytechnic University of Milan.^{[citation needed]} She moved to the United Kingdom for her doctoral research, where she joined Great Ormond Street Hospital. Her research developed computational structure analysis for valved stent technologies.^[1]

Schievano was awarded a research fellowship by the Royal Academy of Engineering.^{[citation needed]} Schievano develops engineering methods for improving human health and disease. She has focused on strategies to enhance safety in first-in-man studies.^[8] She was made lead for the University College London Centre for Clinical Cardiovascular Engineering.^[9] Catheter aortic valve insertion is used in thousands of patients each year, but the replacement valve must be placed in a differently sized tract in each patient. Her early work involved the design of patient-specific tents that were based on the shape and size of people's hearts. These stents were designed using CT scans and finite element methods. She pioneered the use of platinum rhodium, a memory alloy that can be created in different sizes, which could self-expand upon reaching the implantation site, simplifying the surgical procedure. The flexibility of the shape-memory alloy made it more easy to move around the heart's arterial wall. She worked alongside Medtronic to assemble the new stents. Schievano also introduced the stereolithography and laser machines to the clinical procedure, allowing surgeons to practise using a transparent model before the operation begins. The stents developed by Schievano were much less traumatic than most cardiac surgery, and allowed patients to be walking within twenty four hours.^[10]

Schievano is developing new devices to treat children with congenital heart defects. She uses clinical data and computational modelling to assess the dysfunctional sites and promote device personalisation by stimulating implantation and biological interactions.^[11]
