Sawtooth cardiomyopathy

Abstract

Sawtooth cardiomyopathy (STC) is a kind of left ventricular (LV) dysplasia which was falsely classified as a variant of LV noncompaction. Here, we report a young man case with presyncope and dyspnea during exercise. Echocardiographic and cardiac magnetic resonance features showed multiple ridge-like projections of compacted myocardium in the inferior and lateral wall which was compatible with diagnosis of STC.
