The MeDiTATe project will be present at the 14th European LS-DYNA Conference, which will be held in Baden-Baden, Germany on October 18 and 19, 2023.

In this occasion, Eirini Kardampiki (ESR 12) will be presenting the results of her activities with an oral presentation whose title is “Reduced Order Model for enhanced EVAR Planning and navigation guidance”. The work is also authored by Monica Emendi (ESR 11) and other authors from the MEDITATE project including Marco Evangelos Biancolini, Principal Investigator of the MeDiTATe project.

An abstract describing their joint work is as follows: The pre-operative planning and navigation guidance of endovascular aneurysm repair (EVAR) are challenged by the abdominal aortic deformation caused by the insertion of a stiff guidewire during the procedure. Currently, clinicians operate with the support of imaging fusion techniques but still there is a mismatch between the pre-operative CT and the intra-operative aortic configuration. Thus, the use of contrast agent is needed to visualize the vessels. High-fidelity Finite Element simulations can predict the aortic wall deformations, but they are time-demanding, thus not compliant with the clinical timeframe. To tackle this limitation, we developed a parametric Reduced Order Model which predicts the aortic motion in function of seven critical parameters. The accuracy of the proposed ROM was found to be sufficient compared to the resolution of the currently used imaging technologies. The ROM response was provided within some second, showing potential of being employed pre- and intra-operatively.”
