During my clinical training as a Cardiologist I became aware of the diversity of cardiovascular disease and that diversity in imaging is a necessary aim. Cardiovascular MRI’s ability to adapt itself to clinical questions, to expose signs of disease throughout its evolution, and to offer unique tools to evaluate therapeutic response has framed my interest in clinical research.

The CMCR program is a comprehensive clinical research program that is dedicated to the exploration of current and evolving MRI techniques at the 3 Tesla field strength. Its primary mandate is to identify and systematically evaluate the prognostic utility of myocardial tissue characterization and its therapeutic impact on invasive therapies, such as; cardiac resynchronization therapy (CRT), implantable cardiac defibrillators (ICD) and ventricular tachycardia (VT) ablation.

Myocardial scar arises when heart tissue is irreversibly injured. Just as the skin scars in response to cuts or burns our hearts scar following periods of low blood flow (myocardial infarction), inflammation (myocarditis) or surgical intervention (ie: for treatment of congenital heart disease). These scars alter how the heart functions, how it responds to therapy, and how electricity moves throughout the heart. The latter may predispose to life-threatening arrhythmias. CMR offers unprecedented visualization of myocardial scar using both 2 and 3-dimensional techniques. We exploit the higher signal from 3 Tesla MRI to view this scar at exceptionally high resolution.
