Abstract

BACKGROUND

Myocardial Infarction is one of the leading causes of mortality and is associated with high morbidity. Morbidity can be significantly reduced by early identification and characterization of the scar lesion into viable or non-viable by Cardiac MRI. After an acute Myocardial Infarction, determining infarct size helps to stratify patient risk and determines the extent of salvageable myocardium.

Though ECHO can demonstrate regional wall motion abnormalities, it can miss infarct in sub-endocardium and normo-kinetic myocardium.

On the other hand, MRI can asses myocardial fibrosis, sub-endocardial infarct and offers unparallel tissue characterization

AIMS AND OBJECTIVES

To differentiate normal myocardium from abnormal myocardium
To demonstrate alterations in signal intensity and tissue characteristics of acute Myocardial infarction
To define regional wall motion abnormalities, site, extent and complications of previous myocardial infarction

RESULTS

We present our experience of cardiac viability study in 75 patients with anginal symptoms and LV Dysfunction due to Coronary Artery disease. These patients had viable and non-viable scars involving different coronary artery territories on Cardiac MRI.

CONCLUSION

Viability assessment by Cardiac MRI can accurately detect sub-endocardial infarct and dysfunctional yet viable myocardium in a patient with Coronary Artery disease .

Viability scanning distinguishes non-viable scar from viable myocardium. While Infarcted myocardium shows delayed contrast enhancement, Ischemic myocardium lacks contrast enhancement because of intact sarcolemal membrane.
