RESUMEN
BACKGROUND: Saw-tooth cardiomyopathy (STC) is an unusual type of left ventricular dysplasia. To our knowledge, six cases have been reported in the literature. Two new cases are presented with a review of all the case reports that have been published. CASE SUMMARY: Two patients with STC were examined. The first one was a 69-year-old woman with shortness of breath on mild exertion and chest pain, and the second was a 49-year-old man with a history of myocardial infarction who required stent implantation and is now asymptomatic. Both patients revealed findings of STC in the cardiac computed tomography (CT). DISCUSSION: When analysing the cases and comparing them to the ones reported in the literature; STC is a generally benign heart disease, although the clinical spectrum can range from asymptomatic to heart failure. Imaging studies such as cardiac magnetic resonance and cardiac CT are essential for the diagnosis.
