Can computed tomography demonstrate ischemic fatty metaplasia in the left ventricle following myocardial infarction?
Computed tomography can identify fatty metaplasia in left ventricular scars following myocardial infarction, which should be recognized as an alternative etiology to arrhythmogenic right ventricular dysplasia.
Replacement of myocardium by fat, particularly of the right ventricle, is often diagnosed as arrhythmogenic right ventricular dysplasia. At autopsy, however, 68% of scars associated with chronic ischemic heart disease have shown fatty metaplasia in the scar. Four patients with a past history of previous myocardial infarctions and computed tomography demonstration of fatty change in left ventricular regions of hypokinesis and infarction are presented. It is proposed that these findings represent ischemic fatty metaplasia, an alternative etiology of fatty tissue replacing myocardium.
Winer-Muram et al. (Thu,) conducted a case report in Previous myocardial infarctions with fatty change in left ventricular regions (n=4). Computed tomography was evaluated on Ischemic fatty metaplasia. Computed tomography demonstrated fatty change in left ventricular regions of hypokinesis and infarction in 4 patients with previous myocardial infarctions, representing ischemic fatty metaplasia.
