Cardiac magnetic resonance provides detailed functional and structural evaluation of Chagas cardiomyopathy, allowing for the detection of myocardial fibrosis and assessment of arrhythmic risk.
This review emphasizes the evolving role of cardiac magnetic resonance imaging as a crucial tool for overcoming the diagnostic challenges of Chagas cardiomyopathy.
May aid arrhythmic risk stratification in Chagas cardiomyopathy; leaves open need for prospective validation before practice change.
Chagas disease comprises a poorly understood and studied clinical scenario, and the Chagas cardiomyopathy is the more representative field of these difficulties. Different from other cardiomyopathies, there is a discrepancy between its severity and poor prognosis and the low efficiency specific diagnostic and therapeutic available tools. Recently, cardiac magnetic resonance has evolved as an important cardiologic method of detailed and accurate myocardial evaluation. It has already been proved as a valuable test for cardiac functional and structural analysis. Considering the vast area that must be studied and researched regarding this cardiomyopathy, cardiac magnetic resonance is being considered an important recent tool for this purpose. The current use of this imaging method for Chagas cardiomyopathy is reviewed. For the proper image interpretation, the relevant pathophysiological aspects are remembered and the natural history of the Chagas disease is briefly reviewed.

Falchetto et al. (2015) conducted a review in Chagas cardiomyopathy. Cardiac Magnetic Resonance (CMR) was evaluated. Cardiac magnetic resonance provides detailed functional and structural evaluation of Chagas cardiomyopathy, allowing for the detection of myocardial fibrosis and assessment of arrhythmic risk.
