Collapse Viability Imaging

Purpose/ Objective

Cardiac MRI has been around for >2 decades, and yet its use is limited. This is due to knowledge gaps and available resources/expertise. By improving education, providers will understand the difference between the terms viability and functional recovery, and how cardiac MRI (late gadolinium enhancement imaging/low dose dobutamine testing) may help provide guidance in treatment of patients with obstructive coronary artery disease. Following this activity, learners will 1. Understand that CMR can define areas of scar, and thus non-viable myocardium 2. Understand that low dose dobutamine can help predict functional recovery of dysfunctional myocardial segments 3. Understand that revascularization or cardiac resynchronization therapy may not help patients who have large scar burden.
