Figure 2. Example of a patient in the undetermined form of Chagas disease with delayed enhancement on cardiac magnetic resonance and abnormal diastolic function.

Short axis delayed enhanced CMR images (panels A & B) showing focal linear hyperenhancement in the basal inferolateral segment (red arrows). Panels C and D depict Doppler mitral inflow and myocardial tissue velocity imaging pattern consistent with impaired diastolic dysfunction in the same patient.
