ICC Distinguished Lecture: Zahra Motamed, McMaster University


As part of its Distinguished Lecturer Series, the Institute of Computing and Cybersystems will present a virtual talk by Zahra Motamed, McMaster University, on October 7, 2022, at 3:00 p.m.

At McMaster University, Motamed directs the Cardiovascular Research Group and is a Professor in the Department of Mechanical Engineering. She holds associate faculty memberships in the Department of Computing and Software, the School of Biomedical Engineering, and the School of Computational Science and Engineering. She is a member of the Thrombosis & Atherosclerosis Research Institute (TaARI) and McMaster Institute for Research on Aging (MIRA).

Moreover, Dr. Motamed is a research affiliate faculty member at the Institute for Medical Engineering & Science and Harvard-MIT Biomedical Engineering Center at MIT (Cambridge, USA). Her research interests are mainly in the areas of translational and basic cardiovascular mechanics to develop long-needed quantitative diagnostic, predictive, and intervention-optimization tools for cardiovascular diseases to support personalized interventions and clinical decision making. A major part of her work has been dedicated to development and validation of advanced multi-scale computational-mechanics and imaging-based algorithms for patient-specific modelling of cardiovascular system with the following objectives:

Title of presentation: The critical role of diagnostic, monitoring, and predictive tools in patients with valvular disease and TAVR

Abstract: The main functions of the cardiovascular system are to transport, control and maintain blood flow in the entire body. Abnormal hemodynamics greatly alters this tranquil picture, leading to initiation and progression of disease. These abnormalities are often manifested by disturbed fluid dynamics (local hemodynamics), and in many cases by an increase in the heart workload (global hemodynamics). Hemodynamics quantification can be greatly useful for accurate and early diagnosis but we still lack proper diagnostic methods for many cardiovascular diseases because the hemodynamics analysis methods that can be used as engines of new diagnostic tools are not well developed yet. Furthermore, as most interventions intend to recover the healthy condition, the ability to monitor and predict hemodynamics following particular interventions can have significant impacts on saving lives. Despite remarkable advances in medical imaging, imaging on its own is not predictive. Predictive methods are rare. They are extensions of diagnostic methods, enabling prediction of effects of interventions, allowing timely and personalized interventions, and helping critical clinical decision making about life-threatening risks based on quantitative data. Dr. Motamed and her team has developed innovative non-invasive image-based patient-specific diagnostic, monitoring and predictive computational-mechanics framework for patients with valvular disease and TAVR. Currently, none of the above metrics can be obtained noninvasively in patients and when invasive procedures are undertaken, the collected metrics cannot be by any means as complete as the results that Motamed lab’s framework provides.
