Assessment of myocardial viability is an important step in the evaluation of patients with heart failure. In patients with obstructive coronary artery disease (CAD) and left ventricular impairment, extensive dysfunctional but viable myocardium is associated with poor prognosis, which can be reversed by appropriate intervention . A number of non-invasive imaging procedures have been developed to prospectively characterise dysfunctional but viable myocardium and identify markers of functional recovery. The role of viability testing in identifying those patients in whom the benefit from coronary revascularisation outweighs the risk associated to intervention has been documented in many studies [1, 2].
