MR evaluation of myocardial viability in chronic ischemic heart disease

Research output: Contribution to journalReview articlepeer-review


Chronic myrocardial ischemia is a major cause of cardiac injury, often leading to permanent dysfunction and mortality. However, in some cases, injured myocardium remains "viable": it will recover function if blood flow to it is improved. Identification of viable myocardium has prognostic and therapeutic implications in the management of chronic ischemic heart disease. Recent advances in imaging sequences for contrast-enhanced cardiac magnetic resonance (MR) imaging now aliow for identification of the characteristic delayed enhancement in scar tissue with high resolution. This offers several advantages in assessment of viability over stress echocardlographic and nuclear medicine techniques currently in use. These include the fact that MR imaging can be performed at rest and its ability to distinguish subendocardial from transmural scar.
