Transient ischemic dilatation in cardiac amyloidosis.

Myocardial perfusion abnormalities and altered myocardial blood flow have been described in cardiac amyloidosis. Transient ischemic dilatation (TID) on perfusion imaging has been seen in the presence of multivessel coronary artery disease (CAD), hypertrophic cardiomyopathy, significant LV systolic dysfunction and hypertensive cardiomyopathy. But to our knowledge this phenomenon has not been described in cardiac amyloidosis. We present a case of cardiac amyloidosis presenting with transient ischemic dilatation on myocardial perfusion imaging.
