Myocardial viability in preserved or mildly impaired left ventricular function prior to revascularization - findings from a 3 year experience

Background Viability testing prior to revascularization in ischaemic cardiomyopathy has courted controversy in the literature over recent years. Viability assessment prior to revascularization at our institution is largely requested for patients with severely impaired left ventricles (LV). This study however aims to review the outcomes of the patients with preserved or mildly impaired LV function who underwent cardiac magnetic resonance imaging (CMR) for viability assessment during consideration for revascularization and to evaluate its use in this group.
