The main focus of Professor Reza Razavi’s research is imaging and biomedical engineering related to the cardiovascular disease.  One area of focus is cardiac MRI particularly in relation to congenital heart disease, electrophysiology and heart failure, image guided intervention, XMR (X-ray and MRI) guided cardiac catheterisation and methodological advances to move to faster 3-Dimensional cardiac imaging. His group was the first to perform MRI guided cardiac catheterisation in patients and more recently the first group to carry out entirely MR guided cardiovascular interventions.  In congenital heart disease he has developed techniques for three-dimensional imaging as well as physiological assessment using flow measurements. Using MR guided cardiac catheterisation his group has developed new techniques of measuring pulmonary vascular resistance and compliance. In the area of cardiac arrhythmias and heart failure and devices new biomarkers for therapy guidance and therapy assessment as well as multi-modal techniques for image guided intervention have been developed. Methodological developments in this area include advances in MR acquisition and reconstruction and processing as well as techniques for multi-modal imaging integration. More recent research areas include the use of biophysical computational models to better understand pathological mechanisms and help guide treatments and molecular imaging using newly developed molecular imaging markers both in animal and human models.
