Abstract:
With the increasing use of cardiac MRI, several cases were described as "sawtooth cardiomyopathy" or "tiger heart". The pathological aspects of these rare forms of myocardial dysplasia, frequently assimilated to non-compaction of the left ventricle, and its prognostic implications remain unclear. We present a case of "sawtooth cardiomyopathy" in a patient with a transient ischemic attack. This article aims to determine, with the other clinical cases in the literature, the MRI and echocardiography criteria for the diagnosis of this cardiomyopathy. Sawtooth cardiomyopathy is probably under diagnosed and deserves to be better known.
