CTICasesChagasic cardiomyopathy
Imaging findings
Cardiac MRI shows dilated cardiomyopathy with reduced left ventricular ejection fraction and extensive, non-ischemic late gadolinium enhancement in a subepicardial and mid-myocardial distribution involving the lateral, inferolateral, and septal walls.
Key takeaways
Chagas disease (Trypanosoma cruzi infection) can lead to chronic chagasic cardiomyopathy, presenting as dilated cardiomyopathy with extensive myocardial fibrosis. While some patients demonstrate classic apical aneurysms, others show non-specific non-ischemic myocardial scarring.
